- risk of heart disease
- increased reaction time
- decreased accuracy
- tremors
- aches
- growth suppression

- decreased temperature
sleep conserves energy or keeps use safe from predators but little research supports these ideas
adaptive function
sleep is necessary for cognitive functions and memory formation
cognitive function
darting eye movements during sleep that have brain waves that are similar to brain waves during wakefulness; deep sleep
REM sleep
sleep stages 1-3, not deep sleep
Non-REM sleep
dreams are electrical brain impulses that pull random thoughts and imagery from our memories
activation-synthesis theory
during REM sleep, the unconscious part of the brain is busy processing procedural memory
continual-activation theory
dreaming repeatedly simulates potential threatening events, thus enhancing the mechanisms required for efficient threat avoidance
threat-simulation theory
dreaming discharges emotional arousals that haven’t been expressed during the day
expectation-fulfillment theory
Why don’t we remember dreams?
Our hippocampus sleeps while we are sleeping.
How do we get that sense of deja vu?
The hippocampus malfunctions and indicates familiarity of a situation that you haven’t actually encountered.
