Is 5 hours of sleep enough for a teenager? (14-17 years)

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

Short answer

No

Teenagers aged 14-17 years are recommended 8–10 hours per 24 h. 5 hours is in the band the panel marks not recommended.

What the panels say about 5 hours for teenagers

For teenagers (14-17 years), 5 hours is below both the recommended 8–10 hours and the wider "may be appropriate" band — the panel marks it not recommended. The American Academy of Sleep Medicine's pediatric consensus gives 8–10 hours for this group (AASM uses ages 13-18 years), so 5 hours is outside that range too.

That is 3 hours 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 (4 h) would be not recommended; one hour more (6 h) would be not recommended. Making up the 3-hour gap means a bedtime 3 hours earlier for the same alarm.

In cycles

5 hours is roughly 3 sleep cycles at the 90-minute adult average (4 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.
