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.
The richer, more compelling, or just plain odd dreams seem to occur during the REM cycle, and it's this stage of sleep that the body seems to seek. If you lose a half hour of REM sleep one night, you'll likely make up for with 35% more REM time the next night, a phenomenon known as REM rebound.
