Document Summary
Why do we sleep: recuperative theory, sleep repairs the wear and tear done to our bodies while awake, circadian theories, sleep evolved to encourage inactivity during unproductive and dangerous parts of the day. Effects of sleep deprivation: no change in performance on physical tasks, no change in basic intellectual ability, decreased performance on tasks that require alertness and vigilance (attention, impaired concentration. Irritability: the brain may need sws to recover daily activities but the body does. In rats : every time rat gets into rem sleep, plate starts spinning and they fall in water if don"t wake up, the experimental rat dies in several days. In humans : minimal to no effects on performance, but tere seems to be a need to catch up on rem sleep because. , onset to rem becomes quicker and subjects experience quicker and subjects experience longer bouts of rem.
