Sleep needs by age (hours)

How much sleep you need changes sharply across life: a newborn sleeps almost twice as long as an adult. The ranges below follow the National Sleep Foundation (NSF) and the American Academy of Sleep Medicine (AASM) and are the healthy total across a 24-hour day, including naps for young children. Consistent timing matters as much as the number of hours.

Notes

Frequently asked questions

How much sleep do adults need?
Adults aged 26–64 need about 7–9 hours a night; most do best on 7–8. People 65 and older often manage well on 7–8, with lighter and more fragmented sleep.
How much sleep does a 14-year-old need?
Teenagers aged 14–17 need 8–10 hours. Early school starts and screen time leave many teens short, which affects mood, focus and growth.
Do naps count toward daily sleep needs?
Yes — for babies, toddlers and preschoolers the daily total includes naps. For adults, a short nap is extra rest, not a replacement for a full night.
Is it okay to sleep much longer at weekends?
A little catch-up helps after a short week, but a wildly shifting weekend schedule can disturb your body clock. Steady sleep and wake times all week are healthier.
