sleep - -the natural shift of physiologic and neurologic activity; intended
to be restorative
-time spent in REM per night - -~25%
-time spent in N2 per night - -~50%
-N1/NREM1 - -period between wakefulness and light sleep (falling
asleep)
-NREM2 - -light sleep, accounts for about half of all sleep
-NREM3 and 4 - -deep sleep without dreaming
-REM - -sleep stage where vivid dreaming occurs
-physiological changes during NREM1 - -HR & RR decrease, muscles
relax; usually about 15 minutes
-physiological changes during NREM2 - -HR & RR decrease further and
steady, eye movement stops, body temperature drops, brain produces
"sleep spindles"; lasts about 25 minutes/cycle
-physiological changes during NREM3+4 - -deepest sleep state, lowest
HR & RR, no eye movement, delta brain waves present, tissue repair
and growth occurs, immune system strengthens
-physiological changes during REM - -rapid eye movement, primary
dream stage, paralysis, brain activity increases, HR & RR increase, brain
tissue and cognitive function restoration occurs
-sleep for newborns - -sleep about 16hr/day, no circadian rhythm for
first 4 weeks, enter REM immediately
-sleep for infants - -sleep 15hr/day, 1/3 is REM
-sleep for toddlers - -average 11-13hr/day, nighttime fears and
nightmares become common, need routines/schedules
