Additionally, school feeding programs are increasingly being viewed as a potential safety net and as a social support measure that helps keep children in school.
The first REM sleep period usually occurs about 70 to 90 minutes after we fall asleep. A complete sleep cycle takes 90 to 110 minutes on average. The first sleep cycles each night contain relatively short REM periods and long periods of deep sleep.
Dreams (or nightmares) occur during REM sleep. REM sleep is associated with desynchronized and fast brain waves, loss of muscle tone, and suspension of homeostasis. NREM is considered to be deep sleep (the deepest part of NREM is called slow wave sleep); it shows no prominent eye movement or muscle paralysis.
