💡 About Sleep Cycles
During sleep, your body goes through sleep cycles that typically last around 90 minutes each. Each cycle includes stages of light sleep, deep sleep, and REM sleep.
Waking up in the middle of a sleep cycle can leave you feeling groggy and tired, even if you've slept for a long time. This calculator helps you time your sleep so you wake up at the end of a cycle, feeling more refreshed! ✨
Recommended sleep: Adults typically need 4-6 complete sleep cycles (6-9 hours) per night for optimal health.
