Document Summary
Lack of sleep: sleep deprivation for 100 hours or morae leads to hallucinations, paranoia, and bizarre behaviors. 200 hours = microsleeps, sleep disturbances predicted all cause mortality over the next. Even just six nights of poor sleep in a row can impair normal metabolic and hormonal functioning and over time chronic sleep deprivation = less pain tolerance. Higher risk for accidents, can cause difficulty with studying = more irritability and mistakes. Teens are more likely to drive drowsy and fall asleep. Age 20 is the most likely age to fall asleep at the wheel. There is about 19% memory deficit in sleep-deprived individuals = most people are walking around at only 80% of our potential. Lack of sleep affects cognitive functions much like alcohol: 17-19 hours without sleep = cognitive functioning is at the level of someone with a bac of 0. 05.
