Why Sleep Cycles Matter
Understanding your sleep patterns can significantly improve your energy levels
Sleep Cycles
Sleep occurs in cycles of approximately 90 minutes each. Waking up at the end of a complete cycle helps you feel more rested.
REM & Deep Sleep
Each cycle includes both REM (dream) sleep and non-REM sleep, which has three stages from light to deep sleep.
Optimal Duration
Most adults need 5-6 complete sleep cycles (7.5-9 hours) per night for optimal rest and cognitive function.
