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.
After REM sleep, the individual returns to stage 1 of light sleep and begins a new cycle. As the night progresses, individuals spend increasingly more time in REM sleep and correspondingly less time in deep sleep. How long is a sleep cycle? The first sleep cycle takes about 90 minutes. After that, they average between 100 to 120 minutes.
