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, or rapid eye movement sleep, occurs toward the end of each cycle and is typically the stage for our most lucid dreams. Conversely, non-REM sleep is generally lighter and dreamless, save for a few fragmentary images here and there.
