Sleep cycles Each night we go though sleep cycles each approx 90 mins and consists of falling asleep, then REM and then deep sleep, which is a deep restorative state. We then fall back in REM and then light sleep. These cycles continue through the night. The only thing within our control is sleep onset. The rest should follow on naturally.
