Sleep Disorders in Teens: What Parents Need to Know

Sleep disorders in teens include insomnia, a delayed body clock that makes falling asleep before late at night very hard, sleep apnea, restless legs and frequent nightmares. Parents can help by keeping a steady schedule, managing light, screens and caffeine, tracking sleep for two weeks and talking with a pediatrician when problems last or affect school and mood.

This guide is for parents and caregivers of teenagers who seem exhausted, cannot fall asleep, cannot wake up or are struggling at school because of sleep. It explains the common types, how sleep links to mood, a step-by-step home plan, what to say to a teen and the signs that need a medical visit.

How much sleep do teens need?

Teens need more sleep than most adults. The Centers for Disease Control and Prevention (CDC) recommends 8 to 10 hours of sleep for teens ages 13 to 17, compared with at least 7 hours for adults ages 18 to 60.

Many teens fall well short because of early school start times, homework, activities, jobs and phones. Occasional short nights are common; a regular pattern of not enough sleep, or sleep that does not feel restful, is when it is worth looking more closely.

What are the most common sleep disorders in teens?

The most common sleep disorders in teens are insomnia and circadian rhythm problems, such as a body clock that runs late. Other conditions, including sleep apnea, restless legs and frequent nightmares, are less common but important to recognize.

• Insomnia: ongoing trouble falling asleep, staying asleep or waking too early, often tied to stress or worry.
• Delayed sleep timing: the teen is not sleepy until very late and struggles to wake for school, but sleeps well if allowed to sleep in.
• Sleep apnea: loud snoring, gasping or pauses in breathing, with daytime sleepiness or morning headaches.
• Restless legs: an uncomfortable urge to move the legs, especially when lying still in the evening.
• Nightmares: frequent frightening dreams that wake the teen and make bedtime feel dreaded.

The National Heart, Lung, and Blood Institute (NHLBI) describes circadian rhythm disorders as problems that occur when the body clock is out of sync with the environment, causing symptoms such as extreme daytime sleepiness and decreased alertness.

Is it insomnia or just a late body clock?

The difference is usually what happens when the teen can sleep on their own schedule. A teen with a late body clock often sleeps well and wakes refreshed on weekends, while a teen with insomnia struggles to sleep even when timing is not the issue.

The American Academy of Sleep Medicine (AASM) explains that chronic insomnia involves trouble sleeping at least three times a week for at least three months, and that depression is a frequent cause. Light is a key factor in body clock timing: the National Institute of General Medical Sciences notes that light has the biggest influence on circadian rhythms, so bright evening screens and dim mornings can push sleep later.

How are teen sleep problems linked to mood and anxiety?

Sleep and mood affect each other in both directions: poor sleep can worsen irritability, anxiety and low mood, and anxiety or depression can make sleep harder. That is why a sleep problem can be an early sign that something else needs attention.

The CDC lists trouble sleeping among signs of anxiety and depression in children and teens, along with irritability and physical complaints. MedlinePlus notes that insomnia can be caused by stress, medical conditions, medicines, other sleep disorders, and caffeine, tobacco or alcohol. If sleep changes come with withdrawal or loss of interest, see our guide on teen moodiness vs. depression.

How does poor sleep affect school, driving and safety?

Poor sleep can make it harder for teens to concentrate, remember what they learned, manage emotions and react quickly, which affects grades, relationships and safety. Sleepy teens may seem unmotivated or moody when the real problem is exhaustion.

NHLBI lists decreased alertness and problems with memory and decision-making among symptoms of circadian rhythm disorders. For a new driver, that matters: drowsy driving can be dangerous, and a teen who has nodded off at the wheel or feels very sleepy while driving should not drive until the sleep problem is addressed.

Talk with teachers if you notice a pattern of falling asleep in class or missing first period. A short conversation can help everyone see the issue as a health problem rather than a discipline problem.

What can parents do at home, step by step?

Parents can help most by building a steady routine together with their teen rather than enforcing strict rules. Teens are more likely to stick with a plan they helped design.

1. Track two weeks. Use a simple sleep diary for bedtime, wake time, naps, caffeine and screen use.
2. Set a steady wake time. Keep it within about an hour on weekends.
3. Get morning light. Open curtains or step outside soon after waking.
4. Dim the evening. Lower lights and move bright screens out of bed in the last hour.
5. Watch caffeine. Limit energy drinks, coffee and soda, especially after lunch.
6. Build a wind-down. A shower, reading or calm music at the same time each night.
7. Review together. Look at the diary after two weeks and adjust.

The AASM notes that a typical sleep diary covers two weeks and works best when filled out daily, and advises that parents should limit children's caffeine. Our 7-night family plan for teen sleep and sleep diary guide can help you get started.

What should you say to a teen about sleep?

Lead with curiosity and concern rather than criticism, and focus on how sleep affects things your teen cares about. Lectures about phones tend to shut conversations down.

• "You have seemed really wiped out lately. How is your sleep feeling to you?"
• "What gets in the way of falling asleep?"
• "Would you be up for trying a two-week experiment and seeing what changes?"
• "What would help you wind down that you would actually do?"
• "If it is worry keeping you up, we can find someone to talk to."

If nightmares are part of the picture, ask gently what they are about and whether something stressful or frightening has happened. Frequent nightmares after a difficult event are worth mentioning to a pediatrician or mental health professional.

Example: a hypothetical teen who scrolls until 1 a.m. might agree to charge their phone in the kitchen on school nights in exchange for a later wake time on Saturdays, with the family reviewing how it went after two weeks.

When should a teen see a doctor about sleep?

A teen should see a doctor if sleep problems last several weeks despite good habits, or if there is loud snoring, gasping, pauses in breathing, falling asleep in class or while driving, or sleep problems alongside mood changes. Start with the pediatrician, who can check for medical causes and refer to a sleep or mental health specialist.

Red flags that need prompt attention include:

• Drowsiness while driving or nodding off at school.
• Snoring with gasping or pauses in breathing.
• Sleep problems with hopelessness, withdrawal or talk of self-harm.
• Heavy use of caffeine, alcohol, cannabis or sleep aids to cope.

The AASM recommends cognitive behavioral therapy for insomnia (CBT-I) for chronic insomnia in adults and notes that a sleep study is usually used only when sleep apnea or another sleep disorder is suspected. Ask your pediatrician what fits a teen. Read more in insomnia treatment without sleeping pills. If a teen talks about suicide, call or text 988.

What should Texas parents keep in mind?

Texas parents can start with their teen's pediatrician and school counselor, who can help with referrals and school schedules. Long commutes, early bus times, after-school jobs and hot summer nights can all cut into teen sleep in Texas.

If your teen is a new driver, take drowsiness seriously, especially on long highway drives. Ask your health plan which pediatric sleep and mental health services are covered before scheduling specialist visits; coverage varies.
