# Sleep

## Summary
Most adults need 7 or more hours of sleep a night (CDC: 7–9 for ages 61–64, 7–8 for 65+), and needs are higher for children and teens. Regular schedules and a quiet, cool, screen-free bedroom help; ongoing sleep problems are worth raising with a clinician.

> **General information, not medical advice. See a clinician about your own situation; in an emergency call 911 (US).**
