Is 7 hours of sleep enough for a teenager? (14-17 years)

Updated October 3, 2026 · Sources: NSF panel 2015 · AASM 2016/2015

Short answer

Maybe

Teenagers aged 14-17 years are recommended 8–10 hours per 24 h. 7 hours is outside it, in the band the panel calls "may be appropriate for some".

What the panels say about 7 hours for teenagers

7 hours is outside the recommended 8–10 hours for teenagers (14-17 years), but the NSF panel lists it as "may be appropriate" — a range some individuals do fine on, not a target. The American Academy of Sleep Medicine's pediatric consensus gives 8–10 hours for this group (AASM uses ages 13-18 years), so 7 hours is outside that range too.

That is 1 hour short of the bottom of the range. The ranges include daytime naps for under-fives, and both panels stress that a child's needs change month to month.

One hour less (6 h) would be not recommended; one hour more (8 h) would be within the range. Making up the 1-hour gap means a bedtime 1 hour earlier for the same alarm.

In cycles

7 hours is roughly 5 sleep cycles at the 90-minute adult average (7 h 30 min); cycles run 70–120 minutes, so treat the count as approximate. For a school-morning bedtime, count back from the alarm with the bedtime pages and add the extra hours this group needs.
