Sleep Optimization Tips
Sleep Cycle Science
Each sleep cycle lasts ~90 minutes. Waking up at the end of a complete cycle helps you feel more refreshed.
Optimal Sleep Duration
Most adults need 5-6 complete cycles (7.5-9 hours) for optimal rest and cognitive function.
Fall Asleep Time
This calculator accounts for ~15 minutes to fall asleep. Create a relaxing bedtime routine to optimize this.
Consistency Matters
Try to maintain consistent sleep and wake times, even on weekends, for better sleep quality.
