Teenagers and sleep
Starting around puberty, the time at which kids start getting tired moves later. While it might seem like they need less sleep, in fact, teens need about 9 hours of sleep each night. Unfortunately, most teens do not get the sleep they need.

Teenagers are typically moody. They can go from upbeat to moping in a matter of seconds. It's normal for teens to feel sad from time to time, but when that sadness sticks around day after day, it could be depression. Let's talk about adolescent depression. Teens have a lot of pressures in their lives that can lead to depression. They're growing physically, and dealing with a new surge of hormones. They're fighting for more independence from their parents while trying to figure out their place in the world. Some kids are bullied at school or abused at home. Others are faced with major life changes, like their parents' divorce or the loss of a loved one. Kids who are very critical of themselves or who have low self-esteem are more likely to get depressed. Those with learning disorders, ADHD, or anxiety are also more prone to depression. So, how do you know that your teen is depressed? Look for signs like irritability, fatigue, trouble eating, sleeping, or concentrating, teens who are depressed may start using drugs or alcohol, their attitude changes. Once good kids may start misbehaving, missing curfews and acting up to their parents and teachers. Also, their grades may drop and they may spend more time alone in their room. If these symptoms go on for at least two weeks, have your teen seen by a doctor. When left untreated, depression can increase the risk for suicide. Start with a visit to your family doctor, a psychologist, or a psychiatrist. The doctor will tailor treatment to your teen. Often treatment includes medicine, usually a type of antidepressant called a selective serotonin reuptake inhibitor, or SSRI. Examples are Prozac and Lexapro. Adolescents who are on these drugs need to be watched very carefully for side effects, like nervousness, irritability, and suicidal thoughts or actions. Most teens with depression feel better if they talk to someone. Meeting with a therapist can help them identify the negative thoughts that are causing their depression, and turn those thoughts around. Teens may meet with a therapist alone, with their family, or as part of a support group. Depression can affect every aspect of your teen's life, from school to relationships. Teens who are depressed are more likely to start using drugs or alcohol. Antidepressants and talk therapy can be very good at relieving depression. So if you suspect your teen is depressed, talk about it, and ask for help from a doctor or therapist you trust. Most important, call for help right away if you're afraid your teen might be thinking about suicide. Signs include giving away possessions, talking about hurting themselves, and pulling away from family and friends. Any suicidal thoughts need immediate medical attention.
What Makes it Hard for Teens to Sleep?
Several factors make it hard for teens to get the sleep they need:
- Schedule. The average teen gets tired around 11 p.m. and has to get up between 6 a.m. and 7 a.m. to get to school on time. This makes it impossible to get 9 hours of sleep. Some high schools have changed their hours to start later. Students' grades and athletic performance at these schools improved as a result. Just like their parents, many teens are juggling busy schedules. Weeknight school and social activities cut into teens' quality sleep time. They get home later and have a harder time winding down.
- Homework. The push to succeed can backfire when kids sacrifice sleep to do homework. After a night of too little sleep, your teen may not be able to focus in class or absorb new material. Teens need both work and rest to keep their minds sharp.
- Texting. Phones make poor bedfellows, particularly when they go off in the middle of the night. Teens may think every text message has to be answered right away, no matter how late. Even early evening texts can disrupt sleep. Hearing constant text alerts can make it impossible to wind down and relax into sleep.
Sleep and Teen Health
Like adults, teens who do not get enough sleep are at risk for a number of problems in school and with their health, including:
- Depression and low self-esteem
- Sleepiness and trouble concentrating
- Decline in school performance and grades
- Moodiness and trouble getting along with family and friends
- Greater risk of car accidents
- Tendency to overeat and gain weight
What Parents can do
Teach your teen ways to get a good night's sleep. Then be a good role model and practice what you preach.
- Make rules about bedtime. Going to bed at the same time each night can make it easier for your teen to wind down and drift off. Set a bedtime for your teen, and yourself, and make sure you stick with it.
- Limit nighttime activities. Keep an eye on the number of nights your teen stays at school late or goes out with friends. Consider limiting the number of weeknights your child stays out past dinner.
- Offer homework support. Talk to teens about their class load and homework. If they have a heavy semester, help them schedule homework time and limit other activities. Make sure your kids have a good, quiet place to study.
- Set technology boundaries. Talk to your teen about text messages. Ask how they feel if they do not respond to a text right away, then set a time when texting has to stop. You might make a rule that no devices are allowed in the bedroom after a certain hour.
- Promote relaxing activities. In the hour or so before bedtime, encourage your child to do something relaxing. This might mean reading a book or taking a warm shower. Encourage your teen to explore ways to unwind so sleep can come.
When to Call the Doctor
Contact their health care provider if your teen is not sleeping well and it interferes with their health or ability to do daily activities.
