If your child or teen is sleeping longer, harder to wake, or suddenly needing naps, puberty may be part of the reason. Get clear, parent-friendly guidance on normal sleep changes, growth spurts, and signs that may need more attention.
Share what you’re noticing—like longer nights, daytime tiredness, or extra naps—and get personalized guidance on whether this fits common puberty-related sleep patterns.
Many parents wonder, “Why is my child sleeping more during puberty?” In many cases, increased sleep is a normal part of adolescent development. Puberty brings major hormonal changes, rapid brain development, and growth spurts that can make kids and teens feel more tired and sleepy than usual. Their internal body clock also shifts later, which means they may not feel sleepy early at night but still need a full amount of sleep. That combination can look like sleeping late, struggling in the morning, or seeming exhausted after school.
A teen sleeping a lot during puberty may simply be meeting increased sleep needs. During growth spurts, some kids need more rest than they did just a year earlier.
Puberty often shifts sleep timing later, so even if your child gets enough total sleep, waking up for school can suddenly become much harder.
Puberty and increased sleep in teens can show up as frequent naps, dozing off in the car, or needing downtime after school because their body is working hard to grow.
During puberty, many adolescents need about 8 to 10 hours of sleep per night, and some may seem to need even more during intense growth periods.
Sleeping more during puberty in boys and sleeping more during puberty in girls can both be normal. The exact timing may differ, but increased sleep needs can happen in either case.
A child may need more sleep for a few weeks or months during a puberty growth spurt, then settle into a more predictable pattern again.
If your child seems exhausted even after getting enough hours at night, it may help to look beyond normal puberty changes and consider sleep quality, stress, or other health factors.
If increased sleep comes with falling grades, withdrawal, irritability, or trouble keeping up with normal activities, it’s worth paying closer attention.
Very abrupt increases in sleep, frequent daytime sleeping, or patterns that seem far outside your child’s usual behavior may deserve more individualized guidance.
Parents often ask why puberty makes kids tired and sleepy when they seem healthy otherwise. The short answer is that puberty places heavy demands on the body and brain. Hormones are changing, growth is accelerating, and sleep timing naturally shifts later. School schedules, sports, homework, and screen time can make it even harder for teens to get the rest they need. What looks like laziness is often a real mismatch between how much sleep their body needs and how much they’re actually getting.
Yes, it often is. Many teens need more sleep during puberty because of growth spurts, hormonal changes, and brain development. Sleeping longer, needing extra rest after school, or being harder to wake can all be common.
Most teens need around 8 to 10 hours of sleep each night, though some may seem to need more during periods of rapid growth. Consistent daytime exhaustion can be a sign they are not getting enough quality sleep.
Both boys and girls can sleep more during puberty. The timing of puberty may differ, but increased sleep needs can happen in either sex as the body grows and hormones change.
Normal increased sleep usually fits with growth, later sleep timing, and occasional tiredness. Excessive sleep may be more concerning if your child is tired all day despite enough sleep, naps constantly, or shows changes in mood, school performance, or daily functioning.
Yes. A puberty growth spurt can increase sleep needs for a period of time. Some parents notice their child sleeping longer at night, taking more naps, or seeming especially tired during phases of rapid growth.
