Understanding Sleep Cycles

Sleep Cycles

A full sleep cycle lasts about 90 minutes and includes both REM and non-REM sleep stages.

Optimal Sleep

Most adults need 5-6 complete sleep cycles per night (7.5-9 hours) for optimal health.

Wake Up Refreshed

Waking up at the end of a sleep cycle helps you feel more refreshed and alert.
