About Sleep Cycles
Sleep occurs in cycles of approximately 90 minutes, consisting of different stages including light sleep, deep sleep, and REM sleep. Waking up at the end of a complete sleep cycle helps you feel more rested and alert.
The time it takes to fall asleep varies from person to person. The default 14 minutes is a common average, but you should adjust this based on your own experience.
Remember that individual sleep needs vary based on age, activity level, and health conditions. This tool provides general recommendations and should not replace professional medical advice.
