Is 8 hours of sleep enough for a school-age child? (6-13 years)

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

Short answer

Maybe

School-age childs aged 6-13 years are recommended 9–11 hours per 24 h. 8 hours is outside it, in the band the panel calls "may be appropriate for some".

What the panels say about 8 hours for school-age childs

For school-age childs aged 6-13 years the recommendation is 9–11 hours. 8 hours falls in the panel's "may be appropriate" band: not recommended, not ruled out. The American Academy of Sleep Medicine's pediatric consensus gives 9–12 hours for this group (AASM uses ages 6-12 years), so 8 hours is outside that range too.

That is 1 hour 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 (7 h) would be in the may-be-appropriate band; one hour more (9 h) would be within the range. Making up the 1-hour gap means a bedtime 1 hour earlier for the same alarm.

In cycles

8 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.
