Purely Life's picture

Lack of sleep can have disastrous consequences.

Without adequate rest, the brain's ability to function quickly deteriorates. The brain works harder to counteract sleep deprivation effects, but operates less effectively: concentration levels drop, and memory becomes impaired.
Similarly, the brain's ability to problem solve is greatly impaired. Decision-making abilities are compromised, and the brain falls into rigid thought patterns that make it difficult to generate new problem-solving ideas. Insufficient rest can also cause people to have hallucinations. Other typical effects of sleep deprivation include:

depression
heart disease
hypertension
irritability
slower reaction times
slurred speech
tremors
