What Is a Sleep Cycle?
A sleep cycle is a complete progression through different stages of sleep, including light sleep, deep sleep, and REM sleep. On average, one sleep cycle lasts about 90 minutes. Waking up at the end of a sleep cycle helps you feel refreshed, energetic, and alert.
How the Sleep Cycle Calculator Works
This Sleep Cycle Calculator uses scientific sleep cycle timing to calculate the best times to fall asleep based on your desired wake-up time. It assumes an average of 15 minutes to fall asleep and calculates multiple 90-minute cycles backward.
Why Sleep Cycles Matter
Waking up in the middle of a sleep cycle often causes grogginess and fatigue, commonly known as sleep inertia. Aligning your sleep with natural cycles improves concentration, memory, mood, and overall health.
