💤 About Sleep Cycles
A sleep cycle lasts about 90 minutes. It usually takes around 15 minutes to fall asleep.
- Deep sleep helps physical recovery.
- REM sleep supports memory, learning, and dreaming.
- Waking at the end of a sleep cycle may help you feel more refreshed.
Note:
The sleep-cycle numbers shown here are based on
an approximate 90-minute sleep cycle. However,
sleep cycles—especially in newborns and children—
are not fixed at 90 minutes and can vary
considerably from those of adults.
