What is rest? - ANS A condition in which the body is in a decreased state of activity, results in
feeling refreshed.

How do we wake up? - ANS The RAS is activated with stimuli from the cerebral cortex and from
peripheral sensory organs.
Stimuli - noise, alarm clock, etc.

Brainstem - ANS -RAS and bulbar synchronizing region - both located in the brainstem and
work together to
control the cyclic nature of sleep.

-Hypothalamus - ANS Control center for sleeping and waking. Injury causes altered sleep
patterns.

NREM - stages 1-4 - ANS Stage 1 & 2: 55% of sleep, light sleep.
-Stage 3 & 4: 20% of sleep, deepest states.
-Vitals are decreased, essential for physiological restoration and growth.

REM - ANS -Almost paralyzed, vitals are increased

Stage 1 sleep - ANS -Very light, only a few minutes long. VS & metabolism begin to decrease,
awakens easily, feels
relaxed and drowsy.

Stage 2 sleep - ANS -Deeper sleep, 10-20 minutes long. VS & metabolism continues to

Factors affecting sleep - ANS -Developmental considerations, motivation (want to stay awake,
party), culture - bedtime rituals,
lifestyle and habits (working night shift, physical activity and exercise).
-Exercise will increase fatigue and promote REM & NREM. Exercise within 2-3 hours of
Sleep can hinder effective sleep.

constitutes most of the sleep cycle. Place
infant on back to sleep.
-Toddler: naps during the day, moves from crib to bed, starts to resist going to bed.
