자주 묻는 질문

What is a sleep cycle and why is it important?

A sleep cycle is the repetition of REM and non-REM sleep stages, lasting about 90 minutes. Waking up at the end of a cycle can make you feel more rested.

The results don't seem accurate for me. Why is that?

The calculator uses average sleep cycle lengths. Individual variations exist, so observe your sleep patterns for a few days to find what works best.

Does this calculator account for naps?

No, this calculator is designed for nighttime sleep. Naps can affect sleep cycles, so prioritize getting enough sleep at night.
