If You Wake Up at 9:30 AM, This Is When You Should Go to Bed
Five working bedtimes pegged to your 9:30 AM alarm — pick whichever gets you four to six full cycles.
Why these times?
Sleep runs in 90-minute cycles, and what makes you feel rested isn't just hours — it's where in that cycle your alarm goes off. Wake between cycles and you feel surprisingly fine. Wake mid-cycle and a full eight hours can feel like four. The bedtimes below land you between cycles for a 9:30 AM alarm, factoring in roughly 14 minutes to fall asleep.
Bedtimes for 9:30 AM
| Cycles | Go to bed at | Hours of sleep |
|---|---|---|
| 4 | 3:16 AM | 6h |
| 5 | 1:46 AM | 7.5h |
| 6 | 12:16 AM | 9h |
Which one to pick
Waking up here often signals a Bear or Wolf chronotype. Don't fight it — five or six cycles from the corresponding bedtime is what your body actually wants. Forcing earlier just creates social jet lag.
