Frequently Asked Questions

Why 90-minute sleep cycles?▼
A full sleep cycle lasts about 90 minutes. Waking at the end of a cycle feels easier than mid-cycle, which is why this calculator works in 90-minute blocks.
How much sleep do adults need?▼
Most adults need 7-9 hours per night. This calculator targets 5-6 complete cycles (7.5-9 hours) by default.
