Kako izračunati Sleep
Što je Sleep?
The sleep calculator uses the science of sleep cycles to recommend optimal bedtimes. During sleep the brain cycles through stages roughly every 90 minutes: light sleep, deep sleep (slow-wave), and REM (Rapid Eye Movement). Waking mid-cycle causes grogginess; waking at the end of a cycle feels natural and refreshed.

- 1Average sleep cycle = 90 minutes (can range 80–120 min)
- 2Average time to fall asleep = 14 minutes
- 3Bedtime = Wake time − (cycles × 90 min) − 14 min
- 45–6 cycles = 7.5–9 hours — the recommended range for adults
- 54 cycles (6 hours) is the minimum to maintain cognitive function
