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.
Stage R is referred to as REM sleep or ârapid eye movementâ sleep. The first REM sleep episode generally occurs after 90-110 minutes of sleep, cycling about every 90 minutes thereafter. REM sleep periods tend to be longer later in the night. Our heart and breathing rates increase and become irregular.
