How Much Sleep Does a Teen Boy Need?

Published November 14, 2026 · Written from AAP, KidsHealth and other pediatric sources

Puberty, homework, sports and phones all compete with sleep. Here is what the CDC and the medical groups it cites recommend, and why it matters.

The numbers

The CDC lists 9 to 12 hours of sleep for ages 6 to 12, and 8 to 10 hours for teens 13 to 17.
That means a 12 year old falls in the 9 to 12 hour group, and a 13, 14 or 15 year old needs about 8 to 10 hours.

Why it matters

CDC research links too little sleep in kids and teens to a higher risk of obesity, diabetes, injuries, poor mental health, and problems with attention and behavior. CDC also says too little sleep makes it harder to concentrate and can increase risky behavior, especially unsafe driving once a teen starts to drive.

Most teens are short on sleep

In 2025, about 1 in 4 U.S. high school students got at least 8 hours of sleep on an average school night, and fewer teens have been getting enough than a decade ago. So if your son is tired, he has a lot of company.

Why late bedtimes and early alarms collide

CDC notes that late bedtimes plus early school start times mean most students come up short. The American Academy of Pediatrics has recommended that middle and high schools start no earlier than 8:30 AM, and CDC reported that most U.S. schools start earlier than that.

Things you can try

Pick a regular bedtime and wake time, and work back from his wake-up time to find the right bedtime.
CDC suggests a regular bedtime routine to help children get enough sleep.
Talk about sleep as part of how he feels, grows and plays, rather than as a rule from you.
