What are Sleep Cycles?

Sleep cycles are the natural patterns our body goes through during sleep, typically lasting 90-110 minutes each. A complete sleep cycle consists of four stages:

  • Stage 1 (N1): Light sleep, 5-10 minutes
  • Stage 2 (N2): Deeper sleep, 20-30 minutes
  • Stage 3 (N3): Deep sleep, 20-40 minutes
  • REM sleep: Dream stage, 10-60 minutes

Most adults need 4-6 complete sleep cycles (6-9 hours) per night for optimal health and functioning. The SleepUps calculator helps you align your sleep schedule with these natural cycles.
