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 begins with signals from an area at the base of the brain called the pons (see figure 2 ). These signals travel to a brain region called the thalamus, which relays them to the cerebral cortex â the outer layer of the brain that is responsible for learning, thinking, and organizing information.
