Waking up at the end of a sleep cycle helps you feel more refreshed, alert, and ready to take on the day by preventing sleep inertia.
Recommended Bedtime:
15:00
This calculation assumes a standard sleep cycle duration of 90 minutes. We subtract the total duration of your selected cycles from your desired wake-up time to find the optimal moment to fall asleep.
Explain that sleep consists of 90-minute intervals of light, deep, and REM sleep.
Formula: Bedtime = WakeTime - (Cycles × 90min)
Bedtime = WakeTime - (Cycles × 90min)
Example: Waking up at 6:30 AM with 5 cycles.
Waking up mid-cycle causes grogginess, whereas waking at the end feels natural.
Most adults feel best after 5 or 6 complete cycles per night.
