Back to School Sleep Tips

Ask any parent why the first week back is rough, and they’ll point to homework or new teachers. The hidden culprit is usually simpler: a body clock that’s still running on July time. Late nights, sleeping in, and looser routines all summer add up to a schedule that doesn’t line up with the early school bell. Research from National Sleep Foundation’s 2024 Sleep in America® Poll found 8 in 10 teens don’t get enough sleep.

Reset the Sleep and Wake Schedule Before Day One

Waiting until the night before school starts to fix a summer sleep schedule doesn’t work. Instead, shift bed and wake times by 10 to 15 minutes a day for about a week, until the family lands on the schedule school will actually require.

Sleep needs differ by age, and it’s worth knowing the targets:

• Children: Preschoolers (3-5 years) 10 to 13 hours
• School-age kids (6-13 years) 9 to 11 hours 
• Teenagers: (14-17 years) 8 to 10 hours 

The Teen Body Clock Isn’t Being Difficult, It’s Being Biological

Here’s the part that surprises a lot of parents: teenagers aren’t staying up late out of stubbornness. Chronotype, the biological timing of sleep and wake, shifts later as kids move through adolescence. That shift peaks in the early twenties, which means a 16-year-old’s body may not feel sleepy until well after a 9-year-old’s does, even on an identical schedule.

That biology runs straight into most school start times. It’s part of why the National Sleep Foundation recommends that middle and high schools avoid starting before 8:30 a.m.

Model the Habits You Want Kids to Keep

Telling a teenager to sleep more rarely works as well as showing them what good sleep habits look like in practice. A few habits move the needle for every age:

During the day:

• Get outside, especially in the morning. Natural light helps set the body clock and supports feeling alert when it counts.
• Move for at least 30 minutes. Regular activity builds the drive to sleep at night and eases stress along the way.
• Eat meals around the same times each day. Consistency helps regulate the internal clock, not just the stomach.

At night:

• Skip heavy meals and caffeine close to bedtime.
• Build a wind-down routine and stick with it, even on weekends.
• Put devices away an hour before bed. A dark, quiet, cool room does more for sleep quality than most people expect.

The Bigger Picture

Back to school is a natural reset point, not just for kids’ schedules but for how families talk about sleep. Helping a child become their Best Slept Self^® starts with a schedule that respects biology instead of fighting it. Small, early adjustments this week beat a scramble the night before school starts.
