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.
- REM sleep occurs in bursts totalling about 2 hours a night, usually beginning about 90 minutes after falling asleep. - Dreams, once thought to occur only during REM sleep, also occur (but to a lesser extent) in non-REM sleep phases.
