Set a Bedtime for School Wake-Ups
Work back from the school alarm to a consistent, cycle-friendly bedtime.
💡 Sleep happens in ~90-minute cycles. Waking at the end of a cycle (rather than mid-cycle) helps you feel refreshed instead of groggy. Most adults do best with 5–6 cycles (7.5–9 hours), plus ~15 minutes to drift off.
Kids tips
Enter the school wake-up time to find bedtimes that give a full night of complete cycles.
School-age kids need more sleep than adults — aim for the longer (6-cycle) options.
A consistent bedtime, even on weekends, keeps the body clock steady and mornings easier.
