The Effects of Sleep Deprivation on Brain and Behavior

by S.L.

Sleep deprivation is a commonplace occurrence in modern culture. Every day there seems to be twice as much work and half as much time to complete it in. This results in either extended periods of wakefulness or a decrease in sleep over an extended period of time. While some people may like to believe that they can train their bodies to not require as much sleep as they once did this belief is false (1). Sleep is needed to regenerate certain parts of the body, especially the brain, so that it may continue to function optimally. After periods of extended wakefulness or reduced sleep neurons may begin to malfunction, visibly effecting a person's behavior. Some organs, such as muscles, are able to regenerate even when a person is not sleeping so long as they are resting. This could involve lying awake but relaxed within a quite environment. Even though cognitive functions might not seem necessary in this scenario the brain, especially the cerebral cortex, is not able to rest but rather remains semi-alert in a state of "quiet readiness" (2). Certain stages of sleep are needed for the regeneration of neurons within the cerebral cortex while other stages of sleep seem to be used for forming new memories and generating new synaptic connections. The effects of sleep deprivation on behavior have been tested with relation to the presence of activity in different sections of the cerebral cortex.

The temporal lobe of the cerebral cortex is associated with the processing of language. During verbal learning tests on subjects who are fully rested functional magnetic resonance imaging scans show that this area of the brain is very active. However, in sleep deprived subjects there is no activity within this region (3), (4), (5). The effects of this inactivity can be observed by the slurred speech in subjects who have gone for prolonged periods with no sleep (6).

Even severely sleep deprived people are still able to perform to some degree on a verbal learning test. This implies that some other area of the brain must become active to compensate for the loss of temporal lobe functioning. In fact, activity can be seen in the parietal lobe that is not present during verbal learning tests using rested subjects (5). Greater activity within this region corresponded to better performance by subjects in research studies (7). Still, sleep deprived people do not perform as well on these tests as do fully rested subjects (3), (4). One possible reason for the poorer performance after missing sleep, aside from unregenerated neurons, could be the fact that since the parietal lobe is not usually used to performing tasks such as these it is not as adept at carrying them out. Therefore, when control switches from the temporal lobe to the parietal lobe some speed and accuracy is naturally lost. Interestingly, sleep deprived subjects have been shown to have better short-term memory abilities than their well-rested counterparts (6). Since memory is associated with this region of the cerebral cortex the fact that it is already active in sleep deprived people could make it easier for new synapses to be created, thus forming new short-term memories more easily.

While activity is seen within the parietal lobes of rested people as they think through math problems no corresponding activity is visible within the brains of sleep-deprived subjects. Also, no new area of the brain becomes active while the sleep deprived people work on math problems. Since sleep deprived people can still complete math problems, albeit with less speed and accuracy than a well-rested individual, this data implies that a region of the brain already in use is used for this task (1).

The frontal lobe is the most fascinating section of the brain with relation to sleep deprivation. Its functions are associated with speech as well as novel and creative thinking (5). Sleep deprived test subjects have difficulties thinking of imaginative words or ideas. Instead, they tend to choose repetitious words or clichéd phrases. Also, a sleep-deprived individual is less able to deliver a statement well. The subject may show signs of slurred speech, stuttering, speaking in a monotone voice, or speaking at a slower pace than usual (6). Subjects in research studies also have a more difficult time reacting well to unpredicted rapid changes. Sleep deprived people do not have the speed or creative abilities to cope with making quick but logical decisions, nor do they have the ability to implement them well. Studies have demonstrated that a lack of sleep impairs one's ability to simultaneously focus on several different related tasks, reducing the speed as well as the efficiency of one's actions (8). A person may be able to react to a complex scenario when suddenly presented with it but, similar to the verbal tests, the subject will most likely pick an unoriginal solution. If presented with a similar situation multiple times with slight variations in the information presented the subject chooses the same solution, even though it might not be as applicable to the new senario (9).

Part of the frontal lobe, the prefrontal cortex, has several functions specifically coupled with it. Judgment, impulse control, attention, and visual association have all been related to this region of the cerebral cortex (8). A recent study has shown that the prefrontal cortex, usually the most active area of the brain in rested individuals, becomes more active as a person remains awake for long periods of time (3), (4). This region regenerates during the first stage of sleep, giving a person the ability to feel somewhat refreshed after only a short nap (5). The length of the first stage of sleep cycle is somewhat dependant upon how long the person had previously been awake. The longer the period of wakefulness, the longer the brain remains in the first stage of sleep. When the brain enters into the REM stage of sleep the prefrontal cortex is active once more.

The implications of this data seem to be fairly important in supporting the location of the I-function within the brain. The prefrontal cortex is active whenever a person is awake, no matter how little sleep they have had. Also, this area is active while dreaming. Since the individual is aware of him or herself during both of these instances, but is not aware during the stages of sleep when the prefrontal cortex is shut down, it seems logical that the I-function is located within this region. This indicates that the I-function is what is resting and regenerating during the first stage of sleep. It would be interesting to study prefrontal cortex activity while a person is conscious, but unaware of his or her actions, due to an influence such as drugs or alcohol. According to the results of the sleep deprivation studies little or no activity should be seen in the prefrontal cortex at anytime when the individual is unaware of his or herself.

One of the symptoms of prolonged sleep deprivation is hallucinations (10). This could also be related to the I-function since it is the system that integrates the input from all other areas of the brain. If the neurons composing the I-function become too taxed then the picture in the head that the I-function produces may be more dissimilar from reality than usual. The neurons, under pressure to continue functioning but unable to perform optimally, create an image useful enough for a person to see most of his or her surroundings. Metabolic activity in the prefrontal cortex can drop as much as eleven percent after a person has missed sleep for only twenty four hours (8). As a person loses more sleep or continues to receive less-than-adequate amounts of sleep the neurons become even more taxed and the I-function may begin to generate even less coherent images possibly resulting in temporary insanity.

Another piece of evidence supporting the location of the I-function is that mammals have REM sleep whereas cold-blooded animals do not and mammals have a neocortex, located within the prefrontal cortex, while cold-blooded animals do not. REM sleep stimulates areas of the brain used for learning and memory (10). When a person is taught a new skill his or her performance does not improve until he or she receives at least eight hours of sleep (11). An extended period of sleep ensures that the brain will be able to complete the full sleep cycle, including REM sleep. The necessity of sleep for learning could be due to the fact that sleep increases the production of proteins while reducing the rate at which they are broken down (10). Proteins are used to regenerate the neurons within the brain. Without them new synapses may not be able to be formed, thus limiting the amount of information a sleep-deprived individual can maintain.

One of the possible side effects of a continued lack of sleep is death. Usually this is the result of the fact that the immune system is weakened without sleep. The number of white blood cells within the body decreases, as does the activity of the remaining white blood cells. The body also decreases the amount of growth hormone produced (8). The ability of the body to metabolize sugar declines, turning sugar into fat. One study stated that people who sleep less than four hours per night are three times more likely to die within the next six years (11). Although the longest a human has remained awake was eleven days rats that are continually deprived of sleep die within two to five weeks, generally due to their severely weakened immune system (10), (11), (12).

In a way sleep deprivation studies help us to study the relationship between the brain and behavior in a very unique way by observing how a person's behavior changes as the brain shuts down. By taking images of the brain showing where activity is located it is possible to correlate the behavior exhibited by a subject with his or her brain patterns. Just like a person cannot jog for three continuous days a person's brain cannot operate without rest breaks. Since different regions of the brain rest during different stages of the sleep cycle, sleep cannot be cut short. In fact, if the brain does not receive a break it will soon begin to shut down for periods of microsleep. This is essentially several seconds of actual sleep; delta waves that interrupt the regular EEG of an awake person thereby impairing his or her continuity of cognitive function. Microsleep generally happens directly before performance failure occurs (8). Without sleep our brains deteriorate, and if the argument that brain=behavior is true, then our behavior will also suffer accordingly.

I have a comment and concern with sleep deprivation. Several of my friends actually stay up and get only 3 hours of sleep then go to school and work. They say that they recieve somewhat of a "buzz" as if they smoked a small amount of weed or drank alchohol. Is this anything that has been heard of before?

11/06/2005, from a Reader on the Web

i know for a fact that you can go for more then 11 days with out sleep because i went 4 weeks playing computer games on a bet and won but i would never try it again the last 2 weeks it was hard to tell real from not and the stress has caused me some memory loss

11/09/2005, from a Reader on the Web

Just an suggest a sleep deprived person uses a different portion of the brain for activities such as speech than a rested individual. I have noticed that at times of my own sleep deprivation it's almost as though my subconscious thought processes have been re-routed through my speech centre...or at very least through my "top-of-mind" thought centre. (Please excuse my lack of technical terminology...I'm not especially well researched in this area.) For example I may find myself aware of the fact that I'm short of breath...and subsequently need to remind myself to breathe...or blink...and sometimes find myself verbalising these stream-of-consciousness processes. Perhaps more concerning are those times I have found myself verbalising these processes while driving...along with the other driving-related requirements (ie. indicate now, clutch and brake, left-hand down a bit...) Any thoughts? Has this been observed elswhere or was it something I imagined in my sleep-deprived state? Darren

11/17/2005, from a Reader on the Web

My Colleges and I are begining an independant sleep deprivation study, our goal is to remain awake anywhere from ninety-six to one hundrend sixty-eight hours. We were wondering when the Hallucinations occur\what they entail, and how great the effects are on behavior\health before continuing. Thus far, two of us have been designated to conduct this experiment, and the other two stationed to observe. The two that are being deprived of sleep have been awake for 25 hours, 40 minuets, 45 seconds and still going. Any advise?

12/12/2005, from a Reader on the Web

This is in response to the question posted on 10/15/2005 on the page /bb/neuro/neuro01/web3/Ledoux.html: Yes, I believe this effect would happen in case of moderate sleep deprivation. Serotonin, the neurotransmitter which is used up during the sleep cycles, is partially responsible for mood balance. The longer a person sleeps, the more serotnin gets used up in the brain, resulting in somewhat of a depressed state of mind - the lethargy we feel if we sleep, say, 14 hours straight. (Antidepressant drugs such as Prozac work by inhibiting the excessive consumption of serotonin in the brain.) The reverse of this is when we don't get enough sleep, there is a slight excess of serotonin in the brain, resulting in the "buzz" you mentioned. It's tired hyperactivity, not really an energetic state.

12/16/2005, from a Reader on the Web

I think the "buzz" associated with not sleeping has to do with the hallucinations that being to affect the brain after long bouts with no sleep. I suffer from insomnia occasionally and after a long day at work I am definitly not right in the head.

my mom works most nights from 9:45 pm until 7:30 am. by the time she gets home i am about to go to school so i dont see her during the day. when i am at school she is takind medical classes untill about 2:30 pm. she tries to take a nap until i get home at around 3:30 pm. She hardley eats and she comlains aout gaining weight but no more than 20 lbs. today she threw up. i asked her are u ok. she said its fine ive been doin this for a few months now. "mom , why didnt you tell me?" i said. she replied, " u dont need to kno, its just a fact of survival now." i told her she needs to go see the doctor. she refuses, shes a busy woman. I read somewhere that if u have a serious case of sleep deprevation, then u are able to die within the next 6 years. I love my mom to death and i am starting to get worried , she hardly sleeps and when she does it is for short amounts of time. please email me back and tell me if there is anything i can advise to my mom. I care about her so much and!
i dont want her to be hurt or sick. I would greatly appriciate it. Thank you ... Ty, 31 January 2006


Does lack of sleep increase your appetite? ... Jenna McLaughlin, 5 February 2006


I have a hard time sleeping sometimes, I am guessing insomnia I dont know for sure. I am a student and also work a very physically demanding job. I have found that I can barely work some days and others I have an incredible amount of enerrgy. I have also realized I suffer bouts of depression and was wondering if this is related to the lack of sleep I suffer from. I also at times break down from what I beleive is stress. Could the lack of sleep cause more stress or even make the already present stress even more, for lack of a better word, stressful? Thank you ... Nathaniel Kiser, 17 February 2006


I have suffered from some sort of sleep disorder all of my life. I can sometimes get 2-3 hours a night, usually I do not sleep at all. This lasts for weeks, sometimes months, at a time. I recently completed a sleep study. The test showed that I have leg movements at 60-70x per hour, while the normal rate is 10-15x, when I am actually asleep. However, my brain activity is rapid and constant, as opposed to being stimulated by the leg activity. Doctor's questions seemed to indicate a suspicion of bi-polar disorder, but no other symptoms are present. I was prescribed Requip for the restless legs, but had no success with it.

I experience some mild exhaustion during the day, but never to the point of needing a nap. I have taken the Epworth test and my final score was 1. I do not feel impaired; actually I am quite energetic. I work out 3-4x a week, do not intake caffeine, sugar or any other stimulants. The longest I have gone without any sleep at all is 5 days, then got flu-like symptoms and slept for about 8 hours-a sleep marathon, so to speak. Then back to the same routine.

I am deeply concerned about the long term effects on my body. I am a 37 year old female with no serious health problems to speak of. I have tried numerous sleep aids, ranging from herbal alternatives, over the counter medicines to hard core prescription medications (ex: 800 mg of Seroquel). Shockingly, none of them have helped my sleeplessness. It is almost like I just simply do not have an "off" button.

If there is anyone out there who might be able to shed some light on this problem, or anyone who may be suffering from the same symptoms, I would certainly welcome any commentary and/or suggestions ... BZ, 21 February 2006


I am currently serving in the US Army. I can guaruntee you that i only get around 2 to 4 hours of sleep a night. I work all day and basically all night. I train for war. There are short periods i guess you would call it microsleep, that occur to me when i am driving a humvee. i pass out for i guess 5 seconds which seems like 5 minutes. i do have trouble thinking of solutions and most of the time my words are kind of slurred. Sometimes i cannot stay focus on any task and just sit on a chair staring into the great unknown. Everyone in the army works extremely hard everyday and everynight going without sleep for 3 or 4 days.. probably only getting 2 to 4 hours asleep a night. i feel dead inside. when i am given a task to do and i find it difficult to do that task. i am extremely frustrated and angry and i feel like yelling and screaming at the top of my lungs and then passing out for all eternity. You should do a study of sleep deprivation in the Army. I think you tests would be more accurate than using civilians. the army is said in the army regulation books that we are suppose to get 4 non-consecutive hours of sleep a day. that is bs. you should tell the army that our soldiers need more sleep time. everyday i am angry at not getting enough sleep. i'll stp typing now ... Sean, 26 February 2006


just from my own experience I can tell you that I have not slept more than 2 hours in over a week now...due to stress and a terrible the past I have often used it as a means to acheive a certain level of consciousness for spiritual reasons. But this week has begun to feel like torture. Today I have distressing pinched nerves in my neck, and excruciating pain all along my spine. I cannot get into a position that doesn't hurt. I cannot lift anything or move freely. It is beginning to effect my speech...a few days ago I noticed an increase in irratability but was able to get a handle on it today...however there are some benefits I would like to share: my subconsious is definitely much more accessible. I have noticed a heightened feeling that I am channelling other people's thoughts in chat rooms, and can tell what they are thinking before they say it in person. A huge amount of insight has been dumped on me that I hope I do not forget. Last night, while laying in the dark for about 6 straight hours just contemplating....I had revelations about the rune & corresponding Norse mythology that I had picked out randomly the hour before during a bath. It was incredibly complex and simple at the same time for me to get a firm grasp on its' archetypical meaning, how it applies to me, my particular situation; as well as to ancient man and also other mythologies (i.e., Christian). I really enjoyed this insight as a lot of new knowledge came to me that had escaped me previously. So it has its advantages. Now that I have had that experience, I went to purchase a better mattress and some Nyquil so that I may sleep at least 6-7 hrs. sometime today or tonight, whenever the conditions in my household permit. At this point my subconscious is telling me that there will be health risks if I don't. I have learned to listen to it.

Thanks for letting me share that ... Lou Anne Cavin, 27 February 2006


This was pretty informing thank you. I am doing an open ended investigation in biology on sleep deprivation. Im going to be the experimentation though. Just wondering where I should set my limits for my lack of sleep, I\'ve made sure I have no exams when I do it =P. And I was wondering if this like, was a problem because of the hormones and the insufficient time to like recharge them. So, what hormones they are and what they do. Im gonna go research that now hehe. Thanks. Bye ... Amy, 1 March 2006


Everyone says you can't make up lost sleep. Is this true? ... Reader on the web, 3 March 2006


If I stay up all night and study I seem to do better on tests than when I study in incrimates. Why is that or am I just imagining it?

Secondly I have migraines. I first got them 5 years ago when I was only getting 4-5 hours of sleep. I've been getting 8 hours of sleep for the past 4 years. Why haven't my migraines subsided?

Thank you ... Beth, 3 March 2006


I thought id just add some of my experiences of sleep deprivation and hope it helps this site and anyone with their research.

normally after the first 24 hours i begin to fell as would be expected 'stupid'. in the sense i tend to vier of track of whatever i was doing and easily loose focus. speech is still fine although it may take me a few secoonds more than usual to think of what im actually going to say or do. this cant often lead to me being paused and just stood there in a total blank for 10 seconds or so. after 48 hours aside from being tired logic seems to go out the window. simple tasks become hard to do without concotraing very hard for as something like putting a shoe on.often whilst doing this i can do much like i did before and just stare blankly wondering what i as doing before i carry on again. coming up to the third day which is the most ive been awake, lead me into sort of a dream world where i could doze off standing up and walking. conversations were hard to understand due to the amount of concontration needed. i was pretty much in my own world, so to speak. from the outside i looked as if i were inder sedativews or something with an open mouth and just blank thinking. very simple thoughts ran through my head and life seemed simple to me. thoughts of the weel ahead or anything like that came to mind. just the simple task i have to do in the next hour or so. towards the end of the 3 days even eating became a complicated task and required full concontration. having DESCENT conversation was near impossibe.

as for what was mentioned earlier about a 'buzz' after smoking weed and mixed with lack of sleep. i can describe it as the same as sleep deprivation, but its how you view the effect of it on yourself... you can view it as fun and just another way to be not in the right state of mind , as is the point of most drugs and alcohol.

as a matter of fact im actually going without sleep now, not quite 24 hours but long enough for me.. im going to bed!

hope this was of some help ... Dom, 7 March 2007


i have a severe sleep disorder. i have been going on maybe 8 hours sleep every 2 weeks for the last 6 months. And before that i was sleeping maybe a good 8 hours a week and this has been going on for 4 years almost. can anybody beat this. surely if i am out there and do this other people are too. i am surprised i still am even here ...

As part of a bizarre school project, myself and a group of mates are attempting a sleep deprevation experiment later on in the year(i fell upon your website as part of my researsh stage). The idea is to see who will last the longest without sleep (with a slab of beer at the end to the winner, thats to keep them motivated). i would like it very much to hear from you with an idea of what to expect and also some info of previous experiments done from the past.

How does Al Herpin fit into all this? He reportedly suffered from total insomnia. Did his brain learn to recover, or simply move activity to another portion of the brain without sleep? Did he suffer a long but slow degradation of memory? Sorry I can't find any good mention of him on the net, or provide any more information on the net on him than this: (look at 5.

Your article by SL on sleep deprivation really has helped me. I am a semi-retired radio broadcaster who recently began working a couple hours a day hosting early morning radio programming and doing occasional news anchor duties in order to keep my fingers in the business. I have not yet been able to develop some consistent sleep hours, so I may have 6 or 7 hours of nighttime sleep and other times get only 4 or 5 hours, followed by short afternoon naps, then usually crashing for a major late morning nap at some time during the week.

I noticed that my speech on the air is effected. Yesterday, "inexplicably," I didn\'t finish a word while doing the morning host gig...while I don't remember the word in question, it was something like "spoken" which I pronounced "spokuh," not finishing it with the "n" sound. And on the same day, while doing the news, on too-many newscasts I mispronounced at least one word in a way that just didn\'t add up. From time to time, its possible to mispronounce a word while on the air, but it seemed like there was a disconnect between the split second that I read the word on the copy in front of me and the time the word came out of my mouth. It was a totally different feeling psychologically, than a "normal" on-air mispronounciation. And then a week or two ago, when I had to make a routine "timing" decision whether I had time to do a planned story before the commercial or if I had to make a quick switch to a shorter, unplanned story (this decision had to be made while I was in the newscast reading the copy but thinking ahead to how much time I had left) felt like I was clueless as to what to do. Though this is routine, my thinking was definitely impaired.

All this is to say that Ms. L's article has really helped me understand what sleep deprivation has been doing to my brain. It seems to effect (or is the word "affect") my "thinking" more dramatically than my physicality (though I find myself working out at the gym less than my usually disciplined 5 or 6 day a week workout schedule.) Please thank Ms. L for her article for me. I really need to work much harder on getting to bed around 8 p.m. on most nights, and factoring in a better scheduling around the nights when I have obligations that take me to 11 p.m. ...

It is like when the section of brain that is most active for specific function gets used to the less state of optimal transfer and next section starts cache for function switching over something "bottlenecks" "lags" or slows down, this seems detrimental to length of time used to render descernable output, but may also be slowly acessing the old or first active section and new same time maybe gaining wider length or more less used in that specific routeing of functions process. I find it harder to speak simply, needing more complicated explanations to gain the feeling of "defintion or quoitent correct" nodding head in understanding. Lol the line between actual relevant transfer of understandable "coherant" information v.s. giggity giggity spam blah babble grows <--SMALLER? umm Me thinks the brain on the verge of using all portions due to extreme lengths of slack time (sleep) maybe inherantly affecting perception of reality in a more or less indifferent state i.e. self realization of irrelavance of time to entirety of all existence.Numbers obviously become more dominate rates of optimal language due to universally understood medium words letters are relayed less efficently because of the wide format of interchangeable strings user can understand easier different language regardless of font type etc if relavant numeriacal equivalent is present i.e. health=100 10=*&&*% health=110 or health=90... health could be string in any format of chacters symbols etc but cannot =present amount of self or numbers?

When sleep deprived and using parts of the brain that are not normally used is it possible or been researched that a new telepathic sense can be awakened, for the past few years iv lost a lot of sleep and in the past year iv had 4 or 5 very detailed dreams that came true and theres no way they were coincadence.

Was looking at site to see link between Bipolar Disorder and Sleep deprivation. I am studying to be a psychiatrist. It is interesting to note that many "manic" Bipolar episodes are preceded usually by 2 or more days of no sleep at all or a period of severely deficient sleep patterns. Also note that Bipolar depression is often preceded and associated with oversleeping? Is this (Bipolar) a real mental illness, or is it often "created" and thrown at individuals showing symptoms of temporary insanity or sadness due to oversleep or undersleep respectiveley? I beleive at the least the "real deal" behind many "Bipolar Disorder" most especially mania is extended periods of sleep deficiency or no sleep at all, all of which go against the brains natural ability in mantaining stable levels of serotonin...good sleeping lifestyle practices should be the prescription in many cases rather than throwing Mood-Stabilizers, Anti-Psychotics and other Bipolar Meds at people who are! nothing more than severely sleep deprived or oversleeping ...

CeeCee, 23 September 2006



I don't have anything to comment on but I want to know whether the body temperature of a person increases if the person has slept only for 3 hours at night or even lesser. Or it depends on the time period when he/she has gone to sleep or the temperature or weather of the place. Also does the immunity of the person also reduce due to loss of REM sleep? ... Gayetri Ramachandran, 22 October 2006


I think I'm sleep deprived. I work a condensed work week 4 - 10 hour days. I've been doing this for about 2 years now. I drive 1.5 hours 3 of the 4 days to start work at 6am and end at 4:30pm. I have a three year old who co-sleeps with my wife and I. I usually try to go to bed around 9-10pm to get 6 or 7 hours of sleep before the drive. What usually happens is that my daughter tosses and turns or my wife usually ends up working until midnight, my daughter won't go to sleep easily without both of us there. By the time I get into a really good sleep it's around 12:30am - 1am, during the night my daughter repeatedly kicks off the covers in her sleep. I usually wake up several times a night to cover her back up. Then the alarm clock goes off at 4 in the morning, I shower, shave eat breakfast and then commute to work. I've been experiencing some behavioural problems such as MicroSleeping while driving, or at work, inability to concentrate, focus or staring off into space. When people talk to me I usually hear about the first three words and then drift off into la-la land as my eyes glaze over and drift away from whomever is talking to me. Last Friday at work I tried to explain what I was doing to my boss and couldn't spit it out! I ended up grunting and pointing like a caveman! This lasted about 40 seconds and he looked at me very strangely until I was finally able to spit it out in short sentences.

I think my work is suffering from lack of sleep, my wife notices that I'm listless and zombie-like when I get home. This in turn is affecting my marriage. So with both my marriage and job at stake is there any recommendations that you can suggest.

I would be entirley grateful ... Matt Strawbridge, 22 October 2006



Recently,I happened to come across a fact that getting less than 6hrs of sleep per night actually leads us to diabetes and obesity.Infact,when a person wakes up in a sleep deprived state ,there's a growing drive for high carb foods(in the morning).Moreover,production of insulin in the pancreas is also inhibited in this state.Usually I end up getting just 4-5 hrs of sleep per night and if by chance,I get to sleep some 45mins in the public bus on my way to college.Sometimes I experience slurred language,inability to focus and feeling sleepy all the time.Meanwhile,in the weekend I sleep for around 8-11 hrs and this drives me too lazy and decreased energy.And then the life goes on ... John Kane, 8 November 2006



hello im a middleschooler who todally dosnt agree w/ having to wake up sooo early. ive also read that us teenagers should get more sleep than we do so i think that they should give us more time to sleep, on school days and we should at least try to go to sleep earlier ... Jay Bruner, 14 November 2006


I have also noticed the 'buzz' effect of sleep deprivation, it was kinda pleasant, and I think it's similar to a kind of psychosis, you feel slightly removed from reality, as if having taken a mental painkiller.

Also, I have noticed when sleep-deprived, that it is easy to drift off into a kind of daze, and in these times it's easy to get into a stream-of-consciousness rant about varied unrelated subjects. I would have expected this to be a cause of increased functioning in language/creative ideas parts of the brain, because it seems like more thoughts can escape from your unconscious into the conscious, but your research suggests otherwise.

Another effect of sleep deprivation that I have felt is that when sleep deprived, the body's tollerance for alcohol, (and probably other drugs), is much lowered, so a small amount of alcohol will have more effect on you when you're very tired.

Remember this is all from personal experience and shouldn't be considered empirical/true. Everything I have mentioned is only fit for stimulating ideas ... Mombius Hibachi, 19 November 2006



I have done a great deal of sleep deprivation related training in the military, under the mistaken belief that through practice you can get good at it. Afte around 15 years of service I had a seizure, and all the blood vessels in my left eye popped amongs some other unpleasant effects like forgetting my name. The nuerologist told me there was a good chance that this was caused by a life of repeated bouts of sleep deprivation (after I was tested for a myraid of other things like low blood sugar, and epilepsy). Is there anything that I can do to lessen the effects of sleep deprivation? My job kind of requires that I stay up for long hours in order to survive, and be able to carry out my duties ... Nordeen, 9 December 2006


Its really nice to read people's experiences in life.

please keep on adding guyz....its really interesting to read about what happened to your life style when you got deprived of sleep ... Mr. Yelmar, 27 December 2006


your list for SYMPTOMS of sleep loss leads one to believe you'll just feel "sleepy".

Doctors KNOW about the PSYCHOSIS you can get from it, so you should INCLUDE this on your site.

These symptoms include:

-hallucinations (visual, tactile, smell, taste)
-hearing "voices", most of which or MENTAL VOICES
-total loss of judgement
-false memories
-believing things that aren't true
-following "commands" (when the mental voices tell you to do something)
-"movies" playing in your head where "mental voices & chaaracters" appear & play a "storyline" (like a movie would), which can last for seconds, hours, days, or weeks. and you may BELIEVE it to be REALLY occurring.

please post this so people will KNOW what it is that's happening to them, & people will know WHY they shouldn't sleep deprive themselves ... Dudbubbin, 1 January 2007



For a project i stayed up for 37 hours and i never reached the point where i got hillucinations and actually i didn't really experience any really terrible side effects. I did experience the typical side effects such as headaches, slowed movements and thoughts, but after a span of time i felt normal but around hour 36 i could really feel the drag towards sleep. This article has really helped me with an essay that i have to write for this project and i will be sure to use it as a reference. Hope my input can help you in some way ...

I seem to have woken up to the idea that the symptoms of sleep deprivation can easily be misdiagnosed or misunderstood by others, and,then theres the posibility that the sufferer may believe he or she has other unrelated problems. In my case i began to think that i was autistic to some degree, and as a result i embarked on a course to find out. To cut the story short, i came to a point where it was obvious that prelonged periods of sleep deprivation over a span of some 20-25 years have gradually turned me into a completely different person. I have no motivation to do even the things i've always enjoyed and tasks that require ones undivided attention seems to be too much to handle. I made a lot of mistakes typing this dialogue and had to continually make amends to the text, which to me proof is that disorientation is a key symptom. On a daily basis i wander about the work place not able to do whatever job i've been given, even to the point where i have packed up for the day and gone home. Other days are different to the extent that i suffer a kind of panic attack but afterwards i seem to be fine for a while, but definitely a lot more sluggish. I may be suffering from depression too but i've not looked into that side of the matter as yet.

I was tired when i typed this and it was a chore. I hope its of some help, better still will it result in something that will help me! ... H. Rojewski, 22 January 2007



I start hallucinating after about 3 days of no sleep. I see people everywhere that ive never seen before. They just appear out of the walls and ceilings. All i have to do is stare at a solid object for a few seconds. Sure enough people will start coming through and they usually float up towards the ceiling. Also dark rooms are just full of people floating around and walking through. Once i get some sleep i dont see these things at all. The longer i stay up the more clear and intense these experiences become. I used to take large amounts of Dextromethorphan and would experience these types of things. But i havent touched Dxm in years. Could this be some form of permanent brain damage? ... Jay Grigsby, 4 February 2007

I really hope there is someone out there who can help me with this problem.Some three years ago I was struck down with a nasty dose of Chronic Bronchitis, during that period of illness there was a period of thirteen days when I hardly got a wink of sleep due to continually coughing.I felt dissorientated couldn't think straight and was basically quite poorly. Also in that period I did something Quite uncharateristic of me, I sent an email to a work coleague stating that my presant wife shouted at me because of my incesant coughing and that she would get annoyed if I had not cooked her meal by the time she arrived home from work. I remember saying more or less the same thing to my mother some fifteen years ago when I was married to and alcoholic wife. My presant wife read the email which caused me even more traumer and her daughter will not let the subject drop. Could there be a connection here because I cannot explain why I did such a thing, I love my wife dearly and wouldn't do anything knowingly to hurt her. at the time of the illness I was 63 yrs of age ...

hi... I was wondering about sleep deprivation verses major depression. I've been diagnosed with major depression but I have also had a lot of sleep deprivation. i go back and forth between being deprived of sleep and sleeping for really long periods of time. could my sleep deprivation be the reason for my depression? and if so, why wouldn't my psychologist and psychiatrist have caught that because I've described my sleep patterns to them both. are there other factors in diagnosing major depression that I'm missing? from what i can tell, sleep deprivation has a lot to do with behavior malfunction, speech problems, etc., which are symtoms of depression. anyway, I would really like your advice if possible. thank you for the article - it was fascinating ... Anna, 1 October 2007



I'm 14 and i just had a hallicination the other night but i can't recall what it was, but previous hallicinations i remmember. One hallucination was I was the size of an ant in a forrest at night but i also was a hungry chameleon and was trying to eat myself, no joke. I recall that got out of bed cause i felt odd, so i just went to the bathroom, and while i was on the toilet i felt scared, i got up exited the bathroom and i found myself freaking out, my sister was trying to calm me down. Her point of veiw was she came out to go to the bathroom and she saw me standing there looking at the ground, and she said my name and i started to freak out and said there was a worm on my head, but i thought she asked me if there was a worm on my head and i just went with it, so i start saying "There is a worm on my head get it off!" which i don't remmember, also another was a little more calm but still as stressful, it was black every where and i was as if standing on glass, there were old ruin looking columns every where and i had to choose the one REAL column or the whole universe would cease to exist. I also have ones with strange feelings where my mind thinks in a totally different way that i can't explain, One there was bright light all around me and two pitch black wholes on either side of me, in each whole there was a small Imp, and both kept on coming up at the same time trying to pull me in their hole and split me apart, another was the calmest one, There was a frame arch and i was standing in it, there was a light bulb at the top pointing down, (like on the inside) and i was floating through space and breathing. When i hallucinate my mind thinks TOTALLY different, and anything can make me feel like i'm about to die, another was (i know "Don't watch so much TV." wasn't the case though) it was the same setting as the imp dream was, but i was awake, each Dragon Ball Z villain had a hole 3 villains were there, but they were standing above their hole, and i had to go Super Saiyan or they would kill me but there was a chance i would die if i went Super Saiyan, i was 9 at the time, also random things will remind me of my dreams or hallucinations, such as when i was writing this i was going to write "fourteen" instead of 14 but i thought i had a typo and didn't know how to spell fourteen even though it was correct and i got the Sleep Deprivation "feeling" almost remmembering the hallucination i had last night (but i couldn't). So if anyone can explain my type of Sleep Deprivation or anyone that has similar problems or hallucinations or anyone that knows and has experiance the type of "Feeling" or different type of thinking, please contact me ...

Hi my name is femi, i am 15 years old and i live in essex, U.K. Althuogh i haven't carried out any research on this issue, but what i think is that the human brain is designed in away that everything you do is to a set out programme in your head, so when you sleep your brain recollects the days events and thats why you have things known as dreams. Then theres an unconsious state during the sleep were your brain works in credibly hard to programme the next day. Thats why you feel very tired and heavy even when you haven't done anything hard, this is very evident i.e those who sleep more do anything better than those who do not ... Femi, 30 October 2007

sleep deprived

I suffer from ptsd from Iraq. I hardly ever sleep the longest I have went without sleep is over a month. It seems like I am immune to sleeping pills. I have no problems functioning day to day without sleep and was wondering if this was normal or not. It seems like the less I sleep the more energy I have but at times it drives me bonkers any advice?

Father-Son argument

Hi i am a 13 year old. My dad and i recently got in an argument over sleep, he thought that there is a difference between going to bed at 8 pm and waking up at 8 am, and going to bed at 11 pm and waking up at 11 am. I think this is crazy, you get the same amount of sleep. Who is right???

Serendip Visitor's picture


i think that there is no difference between sleeping at 8 pm and waking up at 8 am or sleeping a 12 am and waking up at 12 pm. As long as you get at least eight hours of sleep its all good. As a thirteen year old sleep doesnt matter to me cause i just like being online talking to friends and i have the energy for it and its the same thing with you i guess. Right? sleeping is sleeping and you really only need 6-8 hours of sleep. Kay bye, ~Yuni Mendoza~ <----- thats my name

Reply to Tomas Jones

Sorry to say this but your dad is right. As a rough rule of thumb sleep before midnight is much more useful than sleep after, the reasons for this are all quite long and complicated.
Going to bed late and waking up late wont kill you though and 12 hours sleep is waayy too much, even for a 13 year old.

I can tell you one thing

I can tell you one thing about the hours that you sleep. I have 5 kids and when I let them stay up late they sleep late so they get their normal hours of sleep, but each of them is horribly cranky the next day EVERY time because they are obviously tired even though they will never admit it. It doesn't make sense, but that's how it works.

not getting enough the sleep we need makes us crazy

I am absolutely agree with you. I think not getting enough the sleep we need makes us crazy. It is hard to do better work and activities under sleep disorder suffer.
Many peoples experienced sleep disorder but not many of them realized that sleep disorder is dangerous for health. Stay away from chemical pills and use natural method to get a sleep is the best way. Regards.

finding solutions to sleep deprivation problems

I seem to have suffered from sleep deprivation since high school but did not investigate the issue until I was in my late twenties. Some of the symptoms that others have described here have been true for me as well. Especially difficulty focusing, reacting quickly verbally, and remembering the details that make a day run smoothly. I used exercise, continual activity, and stressful situations to give me the boost I found I needed throughout the day to feel more alert. (Ironically it seems as though constant change and stress may be a major contributing factor to the deterioration of the quality of my sleep.) About seven years ago I went to get tested for ADD which lead me to a doctor that was familiar with Dr. Amen work and correlations between ADD and diet among other things. Although I didn't end up testing positive for ADD much of the same nutrition therapy worked for me. I had developed extremely tight muscles around my back, neck, and jaw that apparently affected how I rested, even breathed at night. I know that exercise during the day was the only method I had found up to that point that helped me to breath more deeply. I was prescribed an increased dose of magnesium to relax my muscles (w/calcium to ensure no bone loss), and then L-Tyrosine, and 5-HTP (I won't suggest how much since all of these are available at the vitamin store yet should be discussed with a specialist when tailoring to your own diet). Within two days of starting on the Magnesium I felt entirely different upon waking, not groggy and sick, but bright and refreshed, and as though I was a kid again waking on Christmas morning! After two weeks I started to recall things, what people describe as short term memory, remembering where you left your keys etc. I hadn't had a flash of insight/memory in years but that started to return. Of course there are all sorts of complications involved with sustained sleep deprivation since the frontal lobes are important to all kinds of cognition. I'm happy to say though that seven years down the road I'm accomplishing the dreams that seemed out of reach at the time, like starting my own business, and I'm sleeping wonderfully! I feel truly grateful for the help that I've received. It's the happy ending to a difficult journey!

Been there done that, !!! WARNING !!! to all

I work a very physically demanding, time consuming job, I work no less than 15 hours a day at the least and average 17 to 18 on a daily basis. I have suffered the worst effects of sleep deprivation and in no way presume to have mastered the natural need for sleep, the fact of the mater is I get payed extremely well in exchange, it was a calculated risk, and a reasonable sacrifice for me at the time.
for the last 3 months I averaged 5 hours of sleep at most and in several occasions managed some back to back all nighters. I only come home on the weekends and the first night I slept an excess of 16 hours but seriously doubt it made up for much of my sleep debt. I first realized the seriousness of this lifestyle's effects on my health when i went 2 weeks suffering from the same cold whose symptoms just seemed to fade and come back eventually to go away o its own, irritability rose to an alarming rate and came with extreme ease, practically anything that could would tip me over, my emotions where all over he place and the fact that I knew the cause of my problems seemed to mater very little, hallucinations I came to realize aren't all they were hyped up to be, they seemed more like a cruel haze where your imagination runs rampant and manifests it self in a more pronounced manner, Personally most times I could distinguish real from not and it just seems like my imagination suggests itself more aggressively and superimposes its importance over my perspective point of view, rather than trick or confuse my senses it just seems to force me to drift away in a fuzz of doubt and detachment from the immediate situation and train of thought, sorry but no flying pink elephants, not that I was shooting for that or anything, on one occasion I did come to fear for my mental health as on this instance as I tried to fall asleep I experienced terrible auditory hallucinations, disturbing sounds of my thoughts and others manifested into voices, as if someone left the TV on and people where just going on and on talking, I cant remember If i could distinguish what exactly I was hearing but it really put me in a bad place I even got up and walked around to see if I was dreaming or awake, I felt Fragile for the first time in a very long time. furthermore my irritability only rose when my ability to communicate these issues to my wife or friends became impossible due to the affected speech that came out slurred and somewhat incoherent, the words I chose didn't quite fit and no substitutes came to mind immediately further frustrating and infuriating me obliterating any possibility for communication, I knew what I was going through but even reassuring myself was a struggle as i had to word out everything in order for me to understand myself, CRAZY, "LOL" if I was confronted with an issue I'd suffer a sort of systematic collapse where it almost felt like an autopilot switch had been engaged and I just functioned without conscious knowledge of my decisions over my actions, in other words, Basically I acted without prior understanding of the decision to act, I would perform certain tasks without even thinking about the process required to achieve the desired outcome Scary i know but in my opinion not as dangerous as it sounds as I could still decide with some effort what activities to take part in and which were simply too dangerous to even attempt, driving was no exception as I continuously would nod or doze off during even the shortest of trips, on one occasion i fell completely asleep while traveling at 60mph on the freeway, I was behind a Tow truck with a long flatbed, I was about 5 car lengths behind him when it started coming over me almost like passing out, the last thing I remember was me slowly but surely accelerating towards the tow truck in front of me then as I lost myself in the darkness I could swear to you I even had a micro dream or some sort of day dream hallucination at the same time this ever increasingly alarming feeling overwhelmed me to awake from that daze AND as I come to I'm only inches under that flatbed, 'lucky he didn't slow down or i'm sure I would have struck him, immediately I freaked out in panic but without any aggressive reactions I proceeded to retreat my foot off the gas pedal and lengthened again the gap between us and got off the free way immediately after and drove onto the back of a gas station and slept for about 3 hours right there in the back seat of my car. Ultimately The Slurred speech, loss of memory and control, alarming irritability, debilitating attention deficit, the inability to express myself coherently enough to explain myself and the very obvious effects this lifestyle was having on my otherwise excellent health has helped me understand what is meant by Health over Wealth, As i now have greatly improved my quality of life in exchange for an insignificant pay cut, The peace of mind I and my loved ones now enjoy is well worth every penny.I just hope this serves as a warning to others so they don't go as far as I did before realizing the severity of the situation, they might not be so lucky.

Glad I read your comment on sleep's picture

Yea, been there, and done that too

I consider myself to be a healthy person, but for the past possibly 5 months. I haven't been getting enough sleep, due to my 2 year old waking up in the middle of the night, and staying awake, until the next afternoon, before he would go back to sleep. He continued to do this for almost a month. And, I started to notice that I was possibly seeing things that couldn't be explained, because I do consider myself to be rational thinking person that knows reality from the "unreal." LOL! But, yet, I kept having crazy hullucinations thinking that I saw something, but in reality I really didn't, and couldn't explain it. Because the last time I checked, I didn't have any sycic abilities. LOL! And, after reading your comments about what you had went through from lack of sleep. I now understand that, yes. I'm normall. I just need to get some rest. LOL!
However, for the past 3 weeks that's what I've been doing. I go to bed now insteead of staying up late to get some studing done or write a paper. I've finally got my son going back to sleep at normal hours and staying asleep all night long.
And, in retrospect of everything, since I've been getting the much needed rest that I've been depriving myself of; I've noticed that my behavior is more normal and not grippy all the time. I noticed that I'm more alert, when preforming task around the house. I noticed that I can concentrait better, when I do partake in my online classes.
And, the biggest kicker for me is: that when I do become sleep deprived, I have seizuers a result of not getting enough sleep. I average about 2 to 3 a year, due to my not getting sleep. I didn't think that they were the reason that I was having them, until I started noticing that I'm not having them until I'm really...really, sleep deprived. And, I will also inform you that I had never had seizuer before in my life, until I was 32 years old. And, the first one that I had had. I was really sleep deprived due to my 1st son keeping me up late. After the first one, I didn't have another one for like another 2 or 3 years. And, when I did, I noticed yet again that I was really, really sleep deprived and wasn't getting enough sleep. After a while I stated to intake the fact that it seemed as if I wasn't having these seizures, until I've gone long peirods of time without sleep. And sure enough, one day I did a search on the net to see what causes seizure, since I had never had one until I was 31 years old and I'm 37 not. And, I did fid an article on line that stated that lack of rest can cause seizures. And, I said to myself. I be damned. My theory as to why I was having seizures was right. IT's becasue I'm staying up to late and going long periods of time without sleep.
I will admite that I might still spend a few nights not getting the much needed rest that I need. But, now, I try to make it a habbit to get that 7 to hours of rest, if possible, due to the effect that it may have on my health.

Zizi's picture

I agree with this but how

I agree with this but how about the Uberman sleep schedule? It is possible to train the body to go into REM state as soon as sleep occurs, which gives ample time for the brain to become fully rested. The only thing I have been wondering about is whether wounds and injuries heal slower and if there might be complications arising from it.

My Newest Experiment

I have currently gone 33 hours without sleep on purpose. Why? Because its all a part of my experiment. In this experiment, I will go little over 60 hours without sleep in order to hallucinate naturally. I'm doing this so I can get ideas for my novel. So far, I'm a bit irritable (but that's normal for me because I'm irritable everyday of my life), I'm having weird cravings for junk food (mostly chocolate), and I'm not tired. I had weird visions a few hours ago, which I belive is normal during sleep deprivation. I'm able to stay awake by listening to rock music (mainly Beatles and Jack Off Jill) and also by thinking about my novel. Hopefully I don't fall into a coma.

Are you saying you can't sleep?

Interested in your experiment

I am very curious on how your experiment turns out, as I am also doing an experiment on which I will not sleep for 72 hours. How can I contact you? It would be good if we can compare our experience to conclude a more accurate result. On the side note, I experienced a very very tiny amount of weight during the 61 hours that I have been awake. I am using a digital weight scale to measure my weight more accurately, it seems that calories burned is happening into my body more and more as I stay awake. Did this also happen to you?

Reply to Anna October 1,2007

I'm not sure you will get this reply, but I wanted to share with you what I recently learned while researching for my sleep deprivation essay. I must stress, I am not a doctor, but have studied this topic by reading a large number of peer reviewed articles, so I offer you some ideas I have taken from my research. Not only are the symptoms of depression and sleep deprivation strikingly similar, but the structures in your brain actually (strangely) change in nearly the same ways as well. I also learned that anti depressants tended to help both types of patients. If you are like me and prefer not taking medication, there a couple of alternatives. If you can get more sleep, your symptoms should abate. Becoming active might also help. I usually lift weights or go running. If I physically exhaust myself I am able to sleep. On the other hand, sitting around watching TV makes it more difficult to fall asleep. Also, a good diet should help. No junk food & lots of fresh fruits & veggies. Good luck!!

The problem is that, relatively speaking, everyone is different. The things you mention are common things that can help the average person with minor issues, but there are hundreds of factors that affect different people in different ways.

my husband is not sleeping well

My husband as been having trouble sleeping he works the 2nd shift and they changed their hours from 2pm til 10:30pm to 4pm til 12:30am this has started to drastically affect his way of thinking although his thoughts seem to go back further he had never voiced them this is my 2nd marriage and I have a daughter who is 37 and after a long period of no sleep he voiced some very inappropriate things and now that they have been said my daughter doesn't even want to come around he has made her scared and he was suppose to be a father figure for her but in his mind he thought she was sending him sexual signals that he needed to know whether they were true or not and now our whole life together is in deep jeopardy I'm not sure this thing is fixable with my daughter cause what he ask her has just destroyed their relationship in her eyes which has left me in the middle and if what he said to her is true than he has also destroyed our relationship in just one statement if you can help me to shed some light at the end of this dark tunnel we are in I would sure appreciate it.

If nothing has changed yet,

If nothing has changed yet, someone need to convince your husband to make some changes in his life, whether it is finding a new job or sticking to some kind of sleep schedule. Right now everyone is suffering from how he is choosing to life his life and it's not fair to anyone and will not improve until he makes a serious commitment to change.

Chronic Insomnia & Sleep Deprivation

I have been reading all of the comments after the article, and learned some interesting facts about my condition.. mostly; how my insomnia, anxiety and bad dreams may all be connected. I recently went before a judge for SS disability due to anxiety, back pain..etc, and have had even less sleep as of late because I cant stop thinking about that day (telling strangers about my problems),so in the last month I have averaged about 2-3 sometimes 4 sleepless nights per week. I have had memory loss, violent and vivid bad dreams, daytime hallucinations and poor judgement (plus many other symptoms shared with you all). I feel horrible even more now that I just found out that I stole jewelry from my mother and cant remember any of it. Since 1999, I have suffered from chronic insomnia and it has taken its toll on me physically as well as emotionally. Chloral Hydrate used to help, but other sleep meds like ambien, rozerem, etc..cause me to sleepwalk/talk,making it even more difficult getting to, and staying asleep (waking up running into the wall!). My family doesnt believe me and assumes that I am on meth or other drugs that are keeping me awake, and I guess I would think that way too if I hadn't lived with this problem for so long. While I was reading this rather long page, I found myself nodding out,eyes dropping and such.. so I know that I am extremely tired but also know as soon as I lay down and try to fall asleep I will be wide awake, seeing and hearing people in the shadows. I grab an hour or so here and there whenever I can,but I've learned now that by putting too much pressure on myself to go to bed at night will make it even harder for me to get there(real sleep). That last little bit may help others who have the same mind-racing problem. One day I will get over this, I hope. Thanks to Sarah Ledoux, and everyone for making me feel like I'm not the only one who deals with this disorder, and that I am NOT crazy, just deprived. Yours sleepy, Andrew. age-29

Andrew - the single biggest

Andrew - the single biggest problem people posting on here have in common is lack of proper medical attention. Have you seen a sleep specialist? I know a thing or two about this because your symptoms due to lack of sleep are similar to mine with plenty of sleep thanks to Idiopathic Hypersomnia, which I have been battling all my life. Anyone can feel free to email me at

Medical Attention

I have being seeing my primary care physician for over 15 years, he was once a child psychologist and is about the only person I trust talking to about my problems. He never forgets to ask how my sleep has been and we have tried many different medications, some have worked but eased off their helping in time, while others didn't work at all or did the opposite of its indications. To this day I don't see why so many people use stimulants to stay awake, as it is so hard for me, and the affects are detrimental to ones health in so many ways. I prefer a natural good nights sleep without meds, but its so bad at times that I just want to be hit over the head and knocked out! Like I said in my post, the easiest way for me to get any rest is to sleep whenever I am tired, be it during the day or as soon as the feeling hits me..this takes the pressure off trying to go to bed only at night, I only wished it worked all of the time!

Hallucinations ,Bad Dreams & Lack of Sleep

I am an 18 year old student. I just completed my A-levels.After reading the comments here i realised there are many people with the same problem but all seem to be adults and they have the problem due to work and rarely personal problems. At this age i have gone through so much that i cant sleep well. I hallucinate alot. I dont know whether to give it a name of hallucination or just my imaginations. But i am one of the depressed people. I got bad grades even flunked in some. My family is very unhappy of me because i did some really bad things that were against our rules. I belong from A muslim family but we are open minded people. I have enjoyed life so much patying and hanging out with friends that i forgot my limits. My parents caught me. I feel extremely guilty. I even made my parents cry. This feeling of guilt and remorse and continous depression has turned me into a lifeless person.
My family lives in Pakistan but my parents have kept me here alone in Saudi Arabia to keep me away from my company and habbits. I have never spent such a dull life and now when i have to i feel like a prisoner. For past two months i have been crying alot. Day and night i cried, i was depressed, extremely lonely all of a sudden, i used to stare at walls and look at pictures of my lovely brothers and cry as i missed them i missed the funny life i had with my family and friends. Now when ever i go to bed at night i stare in the darkness of the room and recall my past and cry, i imagine beautiful situations with my friends, i imagine having a glamourous life wearing fashionable clothes as i used too once , i have made imgainary friends, named them and i talk to them i feel stupid sometimes but it helps me. I actually have nightmares at night and such bad dreams that i wake up sweating heavily. I even hallucinate in daytime.I try reading a book but cant i imagine going on holidays with friends i imagine soo much that i cant put it to words. I watch tv alot, i use facebook and envy how much ahead my friends have gone whereas my life has come to a complete standstill. I havent even told my best friend about my result and i miss talking to her so much :( Life has come to full stop i dont know what to do i have no activity at all. I regret doing things which i have done in my past, i regret when i recall how my parents cried, i regret even living. Sadly i even tried to commit suicide 3 times. I dont know whats my problem but i am irritated, depressed, i hallucinate, i'm sleep deprived, i cry alot and i have headaches. But by reading the posts here i realised many people are in deep shit its just not me. And it feels really good to share things with people who are complete strangers and Thanks to Mr.Andrew .
Yours Khadija Chughtai :)

Andrew 's picture

Thank you!

Dear Khadija, I hate to hear that you are suffering from sleep disorders at such a young age, since mine started around the same time when I turned over 10 years now. Sleep when you can, when you are tired and take that pressure off of yourself at night. It works sometime and we really need sleep, for those who say things like "get yourself physically exhausted, read a book to get your mind tired and just go to sleep! Its not that hard to do!"
Its so much easier said than done when your own mind and body work against you at night(or any other time we need rest). If it were that simple, do people really think I would continue with this horrible problem? No way, I just want healthy natural sleep..but it seems so far away to get it! I have also attempted suicide a few times, and the last one almost did me in a few years ago.. I was revived after going under for nearly 2 minutes. Please don't try that again, I know how hard it can be because I think about doing so at least 10x per day..the depression, back pain, anxiety and insomnia can make us think that death will become the sleep one finally and desperately needs. Feels weird saying not to do that to someone else(hypocritical maybe,lol), but from experience, it's far worse waking up to everyones disappointment in you,than it is dealing and coping with our problems..Truth is; if we make it out of the abyss, the reward will be the simple satisfaction of knowing you can make it through anything that comes along! Good luck, get some sleep! I know I need some!

Consolation from someone you dont know feels like a blessing!

Dear Andrew thankyou so much for your heart-felt reply. It made me cry even because only those who have gone through the same experience can only understand the really meaning of the pain and agony we go through. I try my best to sleep and stay happy but sometimes life breaks you down so low that theres no retreating back but sharing with people who underwent the same situation gives so much relief..i pray that may you get the inner peace and serenity you deserve and as you have advised me not to do it again i hope that you yourslef have revived to normal self. please dont try taking your life again as it is too precious to be wasted in this way. Every problem has a solution though at times you feel like you are at a dead end but "hope" is something that has kept many alive and we should also have ray of hope inside us that someday God will listen to us and get us out of this mess and relish us with inner peace and happiness. Thanks alot for your consolation it meant alot for me ,weird as it may sound that it means alot to me from someone else but knowing that you have gone through something similar i understand it. May you get all the happiness and love you deserve. You too get lots of sleep and always remember that after every dark night there is a bright morning awaiting for us...:)

i find it funny on the article that it said u cant go without sleep for like 2 weeks. I basically went without sleep for approx 10 years.. the only time i probably slept was when i was unconscious due to sleep meds or drunk. which was mayb a couple of weeks. it is a scary thing, and would not want anyone to go through it. i try not to go on meds, but when i look at it now.. i prob should of gone on meds.. my life was terrible at the time..It is a weird thing.. u know u are not depressed cuz of life, but you dont want to do anytthing cuz u r so tired. u are always thinking it will go away, but it never does.. i think its an illness, in your brain. more of an obsession.. there needs to be more studies done on this..

Chronically sleep deprived's picture

Long term sleep deprivation + extreme bouts of insomnia

I have been an insomniac since I was 6 years old and have been diagnosed with Idiopathic Insomnia. Most sleeping medications do not work for me and the few that do fulfill their function in a different capacity than they were designed for... While they don't put me to sleep they keep me asleep for a long time, but only if I'm severely sleep deprived. Over the last couple years my bouts of insomnia have been getting progressively worse starting with 91 hours no sleep to now being 144 hrs or more before I can go to sleep. Interestingly while I used to get sick after these bouts (pneumonia or other kinds of infections) now I don't despite them being longer. In addition the physical side effects of the lack of sleep (nausea, aches, ect.) have been less noticeable. On the flip side it seems like the mental effects have gotten worse, or I have built up a worse sleep debt. While alcohol is as ineffective as sleeping medications, my sleep specialist told me recently that the buildup of adenosine in my brain, in addition the the other havocs sleep deprivation wreaks on the brain, has made it so I'm functioning as if continually drunk, though I still function at least as well as other people. I'm the kind of person that never studies and remembers almost everything and can learn effortlessly and do complicated math problems in my head (they seem simple to me) but since this even worse sleep deprivation my thoughts feel slow and I find myself doing things I even identify at the time as being stupid (e.g. getting back together with an ex). I never feel well rested anymore and a lot of the times it seems like I'm viewing the world through a fog, not to mention the perpetual headaches. Recently I had my first "major" sleep deprivation hallucination (any others I've had were nothing more that lines not being straight, or phantom sounds that were clearly, or on one occasion music that played whenever it was quiet), which is certainly not pleasant, since now I'm concerned about what else may or may not be a hallucination.

On the plus side there is hope for individuals with idiopathic insomnia, many of whom find traditional sleeping medications, even hypnotics and benzodiazepines, to be ineffective. This comes in the form of the chemical Orexin which was discovered to be the "wakefulness" chemical and may be responsible for idiopathic insomnia and its sufferers resistance to sleeping medications. A company (not sure which) is currently working on the phase II trial for the drug and hopefully it will be on the market soon (I'm signed up for the phase III trial which collects data for the FDA so I'll probably post again when the phase III starts, and probably with more information as well). If it is then maybe I, and others like me such as many people on this forum, will be able to sleep easily in the future. For those who don't understand sleep deprivation its like your brain was dipped in molasses and while you can still have incredible ideas, e.g. I can only write well from a literary standpoint when sleep deprived, the feeling is infinitely unpleasant even without the nasty physical side effects that also start to show up 3 or 4 days in.

lil help and a bit of my thought

i have been going through a very similar thing as you not as long with the distances between sleep my norm sleep cycle is every 48 to 72 before my 2 hr rest for my body. ur brain wants you too accept its schedule but if you can keep ur sleep no matter what just to 2 hrs max you can switch ur brain to actually listen to ur thoughts instead of deceiving you to think its thoughts are yours and start will follow you as long as you keep it from regenerating its conscious thoughts.. may not make sense at first but if have any questions email me ill try to help.

the world will never understand me lol but who cares i understand and i truthfully am the only one that needs to understand my thoughts anyway.
== so tired of being a zombie + time to go into my shell + finally grow my wings ==
Night terrors ? yeah tf right ... when will they tell you who i really am?
== Reality is weak so it compensates for its lack of worth with worldly desires that you only perceive through a process known as sanity but digger a little deeper go inside sanity
find who you are and actually go insane and see life for what it is...

Paranoia= survival keep and listen to it for once .

Have you tried Xyrem or

Have you tried Xyrem or discussed it with your sleep specialist? I wonder if anyone has ever dug into the statistics of the average IQ of people with Idiopathic Insomnia and Idiopathic Hypersomnia because there seems to be a high percentage of very capable but messed up people in our positions.

Multiple Sleep Disorders

I suffer from multiple sleep disorders that culminate in sleep deprivation. First I guess I've suffered from sleep apnea for many years but was recently identified 4 years ago or so. Couldn't use CPAPs due to continued air leakage with all the face masks. So now I use a mouthpiece which seems to work fine. Still diagnosed with sleep hypopnea. The real problem I see though is... in all the sleep studies I've had, five in all, I never reached sleep levels 3 or 4. I just go into 1 then 2 for awhile and pop back awake quite often then zoom on down to REM for a bit a couple times a night and awake fully from that then can go directly back to REM then back to 2 to 1 or just back to fully awake. But never, I mean NEVER do I reach the restorative levels of 3 or 4. I really wonder what that will do to me over the long term. Actually, I see what it is doing to me over the long term. I've become disabled from my high creativity, pressure job. My brain is in a fog most of the time. I was taking those mini naps when driving when I was working which was not a good thing. Now suffer from bipolar syndrome. I take loads of naps but never feel rested. Am gaining weight although some days I hardly eat anything.

Just wanted to throw this one out there to see if anyone else has a similar sort of sleep study and has found some way of dealing with it.

Jordheim's picture

I assume you see a sleep

I assume you see a sleep specialist? What has he/she suggested?

I have been fighting Idiopathic Hypersomnia most of my life and have tried just about everything. I am not disabled too, and have lost my family because of it.

Give me more info, and google "xyrem"

it is rediculously expensive, but if your problem is your lack of stages 3 and 4 it might be your ticket.

Just saw the sleep doctor...

I just saw my sleep doctor/pulmonologist and had a serious discussion about my sleep situation. Unfortunately it's sounding like what I've got now is about as good as it's gonna get due to the other drugs I'm currently one. He did discuss xyrem among others. Due to the propensity towards sleep apnea it would not be recommended . . . may never wake up. He believes the anti depressants are the culprits to my not achieving good sleep. I'm bipolar and on Effexor XR and topomax to assist the Effexor.

So this is as good as it's gonna get. The rest is up to me with exercise and weight loss I guess.

Thanks for your quick response and ideas! I appreciate it!

Jordheim's picture

There are ALWAYS other

There are ALWAYS other angles. What other antidepressants have you tried? Have you tried switching the time of day you take it? It will have a slight energizing effect but when that comes varies from person to person. I tried effexor for a while but went back to good old prozac. My daughter takes lexapro at bedtime and it helps her get to sleep.

7 days/nights no sleep

I woke up one day, and didn't go to sleep for the next 7 nights. I cleaned and did craft and watched night tv, - I did not feel even remotely tired. On day 7, I saw the Dr because I was worried I might have a heart attack or something, I was feeling no ill effects apart from worrying how long I could go without dying.
Dr prescribed me an antipsychotic.. it knocked me out like a rock and I was back to normal sleep from the next day (I only took 1 tablet).

Sleep deprivation.

Some simple rules for those of you not able to sleep as you wish.

1. Stop worrying that you never will be able to sleep. You will..

2. You brain doesn't break, it just works differently from when getting your sleep.

3. Those of you thinking you're awake longer periods, weeks etc. Look at the article, notice 'micro sleep', also realize that at times you won't notice that you have slept.

4. Sh* happens, you can get a sleeping disorder from any of a zillion things. When you have it as a lifestyle, then you have learnt to cope with it. I have, and so will you..

5. What really phucks your sleep up is you getting scared that you won't. Stress and insomnia are bad companion's. Accept that you have it, and adapt.

6. Normally you will be able to function reasonably well without sleep, up to, let's say, three days. After that :) You will sleep, assuming you're not on drugs of course.

7. And 'medicines' Ahh, they are a last resort, and before that you already have given in to panic, right :)

D o n t medicate sleep, the sleep you get when doing so is n o t the one you get normally, so the aftereffects from a prolonged 'medication' may well put you in a worse state than 'waiting it out'..

When you learn to accept it you will be able to handle it too. The article seems very good to me, and all sleep deprivations are a little unique in that nobody is the absolute same :) even though there are common symptoms for us all.

Yoron, Wow. I'm


Wow. I'm speechless. Where did you acquire all of this "knowledge"?

Usually it bothers me when people bash the comments of other people, but when someone posts the most rediculous comment in history i think it may be justified because what you have written is not only stupid, it is an insult to people that have real sleep disorders.

Your having been through a period of mild sleep deprivation, or maybe you did a High School report on it, or whatever, doesn't exactly put you in a position to tell others that there problems aren't real.

I am a hard core workaholic but now officially disabled because of my sleep deprivation even after over 20 years of travelling the country to see some of the best sleep specialists. My problems aren't something that will go away by ignoring them, and neither are others'.

RE: Shyam

Melatonin natural sleep aid that is completely safe. At least I don't think it has any side effects in normal dosages. If you have a CVS or Walgreens nearby, stop in and ask a pharmacist what a good dosage would be and if he can think of any concerns.

SUNDER's picture


If an adult gets 7hrs sleep in 24 hrs from 0400 hrs-1100hrs, for a protracted period, would that qualify for being 'sleep-deprived'? If not,would there be any other ill effects?

Although 8 hours of sleep may

Although 8 hours of sleep may be ideal,7 hours is considered to be enough sleep for most adults.

I go through bouts of insomnia

I had a very bad case a few years ago where I was getting almost no sleep at night, and still going to school, and work. One day my mother came home early from work which was quite unusual, we talked for almost 45 minutes until we had to leave for an appointment I had. I turned around toward my front door to get the car started, but then remembered something I wanted to tell my mother so I turned back around and called out to her. She was gone. Completely disappeared. All the lights in the house were off and I didn't hear anything from any room. I did a quick search of the house calling her, but I got no answer. Finally when I gave up, I assumed I was crazy. I was so devastated that my brain was actually starting to fail that I almost cried. Then suddenly she came out of her darkened room saying she had forgotten something. One of the worst insomnia cases I have ever had.

Sleep Deprivation

I found this article quite interesting as I often spend nights awake, probably due to my lack of routine and waking late in the day at irregular times however I find when I have a lack of sleep, my creativity (especially in writing) is very interesting. I hesitate to say it is heightened but the intricacy of my language (academically) is much more common. I would usually use simple language but I find complex literature much more gratifying. Another point is when I've had no sleep I find it easier to interact with other people and start a pleasant conversation, always having a positive feel and I notice I am perhaps more approachable and passive towards other peoples mistakes.

Unfortunately the mood quickly ends and I become sluggish and tired like you have explained and I call this a 'crash'.

I would be interested to know your thoughts on this.

Thanks very much!

Hope you can help.

I am writing a story and my main character is an insomniac. Currently she sleeps 9 hours a week. I was wondering how badly that would effect her and if I might need to give her a bit more time to sleep. Any information would be much appreciated. Also, she is very studious and bright and she does not exercise at all except she runs a lot (6 hours five days a week)
