🌙Delayed Sleep-Wake Phase Disorder in Teens
Understanding and managing the common sleep pattern shift that affects many teenagers
What Is Delayed Sleep-Wake Phase Disorder?
As they enter their teen years, many kids have trouble falling asleep at their usual bedtime. But sometimes a teen can't fall asleep or wake up at the desired times and has trouble functioning during the day. When this happens for at least 3 months, it's called delayed sleep-wake phase disorder (DSWPD). Delayed sleep-wake phase disorder is one of the most common sleep problems in teens.
DSWPD can cause sleep deprivation (not getting enough sleep), which can lead to problems with focusing, mood swings, and low energy.

🏫School Accommodations and Support
Many schools are recognizing DSWPD as a legitimate medical condition and can provide accommodations:
Possible Accommodations:
- •Later start times or flexible scheduling
- •Excused tardiness for morning classes

❓Frequently Asked Questions About Delayed Sleep-Wake Phase Disorder
Is delayed sleep-wake phase disorder the same as being a "night owl"?
While many teens naturally prefer staying up late, DSWPD is more than just being a "night owl." It's a diagnosable sleep disorder that occurs when a teen can't fall asleep or wake up at desired times and has trouble functioning during the day for at least 3 months. The key difference is the significant impact on daily functioning and the persistent nature of the problem.
Will my teen outgrow delayed sleep-wake phase disorder?
Many teens will grow out of DSWPD as they get older. By the time they reach young adulthood, their sleep-wake cycles often shift earlier naturally. However, some people may continue to have a delayed sleep pattern throughout their lives. The important thing is to manage the condition while it's affecting your teen's daily life.
Can melatonin supplements help my teen with DSWPD?
Melatonin supplements can help some teens feel ready for sleep earlier in the evening. However, it's important to talk to your teen's doctor first to find out whether they're suitable and how much they should take. Melatonin supplements aren't regulated, so ask the doctor which brands are trustworthy. They work best when combined with other sleep hygiene strategies.
How can I help my teen get enough sleep for school?
Talk to your teen's teachers or school guidance counselor to find out whether your teen can avoid having early morning classes. If possible, have your teen change activities scheduled for later in the day to an earlier time. Having more free time in the afternoon and evening can let your teen do homework and talk to friends without having to stay up late.
What is chronotherapy and when is it used?
Chronotherapy can help in more severe cases of DSWPD. This involves moving the bedtime later by about 2–3 hours each night for up to a week or two until the target bedtime is reached. For this to work, your teen will need to be able to sleep during the day for a week or two, so it's best to do it during long vacations or breaks from school.
How does light therapy work for DSWPD?
Light therapy involves exposure to bright lights in the morning to block the release of melatonin and wake up the brain. Your teen should also avoid bright lights in the evening, especially blue light from electronic devices. This helps reset the body's internal clock to an earlier schedule.
Should I let my teen sleep in on weekends to catch up?
While it might seem helpful to let your teen sleep in on weekends, this can actually make DSWPD worse by further shifting their circadian rhythm. It's better to maintain a consistent sleep schedule, even on weekends, to help regulate their body clock. Small adjustments (1-2 hours) are okay, but major schedule changes can be counterproductive.
How do I know if my teen's sleep problems are serious enough to see a doctor?
If your teen has trouble falling asleep and waking up at needed times for more than 3 months, and it's affecting their daily functioning (school performance, mood, energy levels), it's time to see a doctor. Also seek help if your teen can't sleep or acts differently than usual, or if basic stress relievers aren't enough to help.
Can DSWPD be genetic?
Yes, DSWPD can run in families, meaning it could be genetic. A teen may be more likely to develop DSWPD if a parent had it. This genetic component helps explain why some teens are more affected by the natural circadian rhythm shift during puberty than others.
What's the difference between DSWPD and insomnia?
DSWPD is a circadian rhythm disorder where teens can sleep well, but at the wrong times. Insomnia is difficulty falling asleep or staying asleep regardless of timing. With DSWPD, teens can usually sleep well when they're allowed to follow their natural sleep schedule, but they struggle when forced to sleep at conventional times.
