## Sleep Cycle Planning

A complete sleep cycle lasts approximately 90 minutes and includes light sleep, deep sleep, and REM sleep.

**Ideal Wake Time = Bedtime + Fall Asleep Time + (90 min x Cycles)**

### Recommended Sleep Cycles

| Cycles | Sleep Duration | Best For |
|---|---|---|
| 4 | 6 hours | Minimum rest |
| 5 | 7.5 hours | Most adults |
| 6 | 9 hours | Recovery, teens |

Waking at the end of a cycle (during light sleep) makes you feel more alert than waking mid-cycle.
