circadian rhythm
daily rythmic activity cycle based on 24hour intervals
Stage 1 of sleep
- very light sleep, if not disturbed person will move onto 2nd stage
- muscle contractions (Hypnic Myoclonia) occur and are preceeded by the feeling of falling
Stage 2 of sleep
- person starts to think of images but no visions are seen with your eyes
- if undistrubed, drift off into stage 3
Stage 3 of sleep
- deeper sleep, muscled are relaxed, and HR is slowed down, BP is falling, breathing is steady and even
- hard to be woken up
Stage 4 of sleep
- dreaming stage
- deepest sleep of all stages
- person usually only wakes if there is a sudden loud noise.
- BP, HR, and brain speed up
when does sleep walking, night terrors, and bed wetting occur
stages 3 &4 of sleep
stage 5 (REM sleep)
- if awakened now..most dreams will be remembered
- REM slows as person wakes
- adults have 3-5 periods of REM a night
- REM is about 90% of time
- brain and eyes move fast
percenatge of time in each sleep stage
- 50% in stage 2 sleep
- 20% in REM
- 30% in other stages
- infants spend 50% in REM
sleep cycles
- 90-110 minutes each cycle
- first cycle of night is short REM periods and long deep sleep periods
- as night progresses–REM increases and deep sleep decreases
- by morning–all sleep is either stage 1 or 2 or REM
Sleep disruptions
-if REM is disturbed, our bodies don’t follow normal sleep cycles next time around–we slip directly into REM until we catch up
sleep needs/ different ages
- infants 18-20 hrs/day
- babies-16 hrs/day
- teens-9hrs/day
- adults 7-8hrs/day

heavy smokers and alcohol use sleep issues
- alcohol deprives person on REM sleep
- smokers often decrease REM sleep because wake every 3-4 hrs from nicotin withdrawal
sleep apnea
-interruption of breathing during sleep
-often associated with obesity, enlarged tonsils, decreased muscle tone due to aging
-airflow obstructed for 10-60 sec while person struggles to breath due to suction collapsing wind pipe
blood oxygen levels fall= person awakes
-person is always sleepy=possible personality change/ depression
sleep apnea risks
- morning headaches, decline in mental functions, disinterest in sex, increased BP, irregular heart beat, increased risk of stroke or MI
- increased risk of MVA’s and sudden respiratory arrest during sleep
how to help sleep apnea
- lose weight, sleep on back, or surgery to remove obstruction
- CPAP (continuous positive airway pressure device) while sleeping
- never take sedatives or sleeping pills
Restless leg syndrome
- hereditary disorder causing unpleasant crawling, prickling, or tingling of legs and feet
- causes person to wake often with urge to move feet
- often associated with anemia, pregnancy, and diabetes
