If your child plays a sport, you’ve probably noticed the trade-off: early practices, late games, homework, and a phone that never seems to power down at bedtime. Somewhere in that schedule, sleep is usually the first thing to get squeezed — and it’s also the thing your young athlete can least afford to lose.
This guide breaks down exactly how much sleep kids and teen athletes need by age, why sleep matters more for athletes than for other kids, and practical ways to help your young athlete actually get the rest their body needs to grow, recover, and perform.
Quick Answer
School-age athletes (6-12 years old) need about 9 to 12 hours of sleep per night, and teen athletes (13-18 years old) need about 8 to 10 hours — generally at the higher end of the range recommended for non-athletes their age, since intense training adds extra recovery demand.
Sleep Needs by Age Group
These ranges come from pediatric sleep medicine guidelines and are worth using as your baseline, then adjusting up when your child is training hard. Children ages 6 to 12 should get roughly 9 to 12 hours a night. Teenagers ages 13 to 18 should get roughly 8 to 10 hours a night. Younger kids in organized sports (preschool age and up) still fall under general pediatric guidelines, but the same principle applies: more activity generally means more sleep is needed to recover.
For athletes specifically, aim for the top end of these ranges rather than the minimum. A young athlete grinding through two-a-day practices, tournament weekends, or a growth spurt often needs more sleep than a less active classmate the same age — not less.
Why Athletes Need More Sleep Than Other Kids
Sleep isn’t just downtime — it’s when the physical work of training actually pays off. Deep sleep is when the body releases the most growth hormone and does the bulk of muscle repair, tissue recovery, and immune system maintenance. Skimp on sleep and a young athlete is essentially cutting their recovery window short, no matter how well they trained or ate that day.
Sleep also affects the things that make or break performance in the moment: reaction time, coordination, decision-making, and focus. Athletes who get more sleep tend to perform better in areas like sprint speed, accuracy, and reaction time compared to when they’re sleep-deprived.
There’s also a real injury connection. Research on adolescent athletes has found that those who regularly sleep less than 8 hours a night are significantly more likely to sustain a sports injury than peers who meet sleep recommendations — one commonly cited figure puts the risk at about 1.7 times higher. Tired muscles react slower, joints are less stable, and judgment on the field or court suffers, which is a recipe for rolled ankles, overuse injuries, and worse.
Sleep loss in young athletes has also been linked to more anxiety, low mood, and trouble concentrating in school — so the effects show up well beyond the field.
Tips and Common Mistakes
Work backward from wake time. If your athlete has to be up at 6 a.m. for a meet, count back 9-10 hours to set a real lights-out time, and protect it the way you’d protect a practice schedule.
Cut screens before bed. Phones, tablets, and TVs delay the body’s natural wind-down and make it harder to fall asleep even when the hour is late enough. Aim to power down devices 30-60 minutes before bedtime.
Don’t rely on weekend catch-up sleep. Sleeping in on Saturday doesn’t fully undo a week of short nights — consistency matters more than occasional long sleep-ins.
Watch caffeine, especially in the afternoon. Energy drinks and soda close to bedtime are a common and underrated reason teen athletes struggle to fall asleep.
Treat naps as a tool, not a crutch. A short nap (20-30 minutes) earlier in the day can help on heavy training days, but late or long naps can push bedtime back even further.
A common mistake parents make is treating sleep as flexible around a busy sports schedule, when it should be treated as part of the training plan — as important as the practice itself.

Sleep needs for young athletes FAQs
How many hours of sleep does a teenage athlete need?
Teen athletes (13-18 years old) should aim for about 8 to 10 hours of sleep per night, leaning toward the higher end during intense training periods, growth spurts, or competition season.
Can lack of sleep really increase injury risk in young athletes?
Yes. Studies on adolescent athletes have found that those sleeping less than 8 hours a night are considerably more likely to be injured than well-rested peers, likely due to slower reaction times and reduced coordination.
Do naps count toward a young athlete’s sleep needs?
Short naps (20-30 minutes) can help supplement missed nighttime sleep, especially on heavy training days, but they shouldn’t be relied on to replace consistent, adequate nighttime sleep.
What’s the best way to help a young athlete sleep better before a big game?
Keep the pre-bedtime routine consistent, limit screens and caffeine in the evening, and stick to the athlete’s usual sleep and wake times rather than drastically changing the schedule right before competition.
