Sleep Cycle Calculator
Calculate ideal bedtimes and wake-up times aligned with human 90-minute REM sleep cycles to wake up feeling refreshed.
How It Is Calculated
Humans sleep in 90-minute cycles alternating between light sleep, deep sleep, and REM. Waking at the end of a cycle avoids grogginess.

Understanding the Sleep Cycle Calculator
Waking up in the middle of a deep sleep cycle triggers sleep inertia, leaving you feeling exhausted and groggy throughout the morning. Aligning your alarm with the completion of a full 90-minute cycle ensures effortless waking.
