Recommended Teen Sleep Duration

The National Healthy Sleep Awareness Project has launched the “Sleep Recharges You” campaign, urging teens to make sleep a top priority. Parents and teachers can play an important role by helping teens to understand the importance of sleep.

The American Academy of Sleep Medicine recommends that teens should sleep 8 to 10 hours each night to promote optimal health. But CDC data show that insufficient sleep is common among teens. About 69 percent of high school students report sleeping 7 hours or less on school nights.

This ongoing sleep loss can hinder teens’ learning ability in the classroom. It also can impair their athletic performance.

Even worse, teens who sleep less than 8 hours on school nights are more likely to make bad choices that put their health at risk. CDC data show that sleepy teens are more likely to:
  • Smoke cigarettes or marijuana
  • Drink alcohol
  • Be sexually active
  • Get in fights 
High school students who don’t get enough sleep also are more likely to feel sad or hopeless. These mood problems can have devastating consequences. Sleep-deprived high school students are nearly two times more likely to seriously consider attempting suicide.

Failing to get enough sleep also can be a threat to teens’ safety on the road. CDC data show that high school students who sleep less than 8 hours on school nights are more likely to drink and drive. They also are more likely to text while driving. Drivers between the ages of 16 and 24 years also are 80 percent more likely to be in a drowsy driving accident.

As a parent, you should model healthy sleep habits in your home. You also should help create a healthy sleep environment for your teen. Ensure that your teen’s bedroom is free from electronic devices – no TV, computer or video game system.

How early your teen has to wake up for school is a key factor that impacts his or her sleep duration. A natural shift in the timing of the body’s internal “circadian” clock occurs during puberty. As a result, most teens have a biological preference for a late-night bedtime.

A recent CDC analysis found that the average start time of U.S. public high schools was 7:59 a.m. Only 14.4 percent of public high schools started school at 8:30 a.m. or later. Among all states, Louisiana schools reported the earliest average start time of 7:40 a.m. The American Academy of Sleep Medicine encourages parents and local school boards to work together to implement high school start times that allow teens to get at least 8 hours of nightly sleep.

    My middle school children have to get on the bus at 6:11 am.  School starts at 7:29.  We are in Michigan.  Some sporting events that kids attend are 1 hour and 20 minutes away.  Kids are arriving at the school at 9:30 at night.  We shoot for an 8 pm bedtime, but are lucky to hit 9 on most nights.  I was always tired at school.  We need to do more to get the kids to start later.  Here it is a matter of funding.  6th-12th grade gets bused first, then K-5.  K-5 starts at 7:24 in our district.  Rest up kids! Kick the devices to the curb.  Not worth the trade off.  Although as an adult my sleep hygiene is terrible too.  I am still guilty of a Netflix binge every now then that puts me at 5 hours a sleep a night, when my body really needs 10.  I have to play catch up on the weekends.  Best regards from Michigan!

    Not only is it difficult for us teens to get enough sleep because of homework, extra curricular, etc, but stress is also a common factor. When my friends are stressed about social drama or a big test, they often find it hard to go to sleep, sans drugs or alcohol already. There are so many factors that go into each night of sleep, showing that it is all the more essential to get a sufficient amount.

    I am a current high school student and I am able to get my 8-9 hours of sleep every school night. I set my priorities such as homework first; if I have time I'll do them in class or if not   Right after school when I get home. Once  done I can relax for a few hours and get in bed around 9 or 10 depending on my energy level. I am healthy, happy, and stress free :)

    It's hard enough for teens to get proper amounts of sleep without having a sleep disorder. However, if they're getting 8 or more hours of sleep each night and still sleepy, they could be suffering from sleep apnea. It's worth looking into.
