Is 9 hours of sleep enough for a teenager? (14-17 years)
Updated October 3, 2026 · Sources: NSF panel 2015 · AASM 2016/2015
Short answer
Yes
Teenagers aged 14-17 years are recommended 8–10 hours per 24 h. 9 hours is inside that range.

What the panels say about 9 hours for teenagers
For teenagers (14-17 years), 9 hours sits inside the 8–10 hour range the National Sleep Foundation panel recommends. The American Academy of Sleep Medicine's pediatric consensus gives 8–10 hours for this group (AASM uses ages 13-18 years), so 9 hours also passes by that measure.
It is in the middle 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 (8 h) would be still within the range; one hour more (10 h) would be within the range. Holding this on school nights and weeknights alike matters more than the exact figure.
In cycles
9 hours is roughly 6 sleep cycles at the 90-minute adult average (9 h); 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.
