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.
During REM sleep, your brain and body are energized and dreaming occurs. REM is thought to be involved in the process of storing memories, learning, and balancing your mood, although the exact mechanisms are not well understood. REM sleep begins in response to signals sent to and from different regions of the brain.
