sleep
25 hour cycle guided by environment (light and temperature) and biology (genetics)
2 types of sleep

80% of the time
heart rate, breathing, bp slowing down
REM: 20% of the time heart rate, breathing, bp speeding up dreaming sleep paralysis

transition from wakefulness to sleep
1-7 min
theta waves (low amp + low frequency)
somewhat aware of surroundings
stage 2 of sleep

body begins to slow down
more difficult to wake
beginning of sleep spindles
stage 3 of sleep
delta waves
body continues to slow down
stage 4 of sleep

secretion of growth hormone that helps brain development
difficult to wake
REM sleep
dream
muscles paralyzed
heightened brain activity and breathing
insomnia
lack of sleep and/or inability to stay asleep
sleep apnea
stop breathing while sleeping and wake up constantly or don’t wake up; CPAP machine pushes O2 into lungs
correlation with obesity and high bp
somnambulism
sleep walking
somniloquy
