Is 4 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. 4 hours is in the band the panel marks not recommended.

What the panels say about 4 hours for teenagers

4 hours is well under the 8–10 hours recommended for teenagers aged 14-17 years; the NSF panel lists it as 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 4 hours is outside that range too.

That is 4 hours short of the bottom of the range. For children the figure includes naps, and the panel's ranges are wide on purpose — individual needs vary with growth and activity.

One hour less (3 h) would be not recommended; one hour more (5 h) would be not recommended. Making up the 4-hour gap means a bedtime 4 hours earlier for the same alarm.

In cycles

4 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.
