What Is Delayed Sleep Phase Disorder?
Delayed Sleep Phase Disorder (DSPD) is a circadian rhythm sleep disorder characterized by a significant delay in a person’s sleep-wake cycle compared to the average population. People with DSPD may struggle to fall asleep until very late at night (or early in the morning) and have trouble waking up in time for morning activities.
While night owls may occasionally stay up late without suffering any negative consequences, it can be difficult for individuals with DSPD to adjust their sleep schedule to their lifestyle. Failing to treat DSPD may lead to chronic sleep deprivation and negatively affect a person’s physical and mental health.
Symptoms of Delayed Sleep Phase Disorder
Here are the most common signs of DSPD you should look out for:
- Inability to fall asleep at a desired or reasonable time
- Difficulty waking up in the morning
- Sleeping significantly more on weekends or days off
- Feeling tired and drowsy during the day
- Struggling to concentrate and remain alert
- Sleeping poorly at night (frequent awakenings, restless sleep)
In some cases, DSPD may lead to insomnia—if you cannot sleep at night and feel unwell during the day, you may want to consult a medical professional.
Causes of Delayed Sleep Phase Disorder
At the moment, there is no consensus on the root cause of DSPD. Nevertheless, you may develop this disorder if you fit one or several of these criteria:
- Genetics. If one of your parents suffers from DSPD, there is a higher chance you will have the same issue.
- Age. Teenagers and young adults are more prone to DSPD than older people.
- Poor Sleep Hygiene. Often DSPD is preceded by bad sleeping habits—exposure to bright light before bed, lack of a consistent schedule, an uncomfortable sleep environment, and caffeine consumption in the afternoon.

How Is Delayed Sleep Phase Disorder Diagnosed?
If you suspect you or your child has DSPD, it is important to visit a doctor who will be able to diagnose the disorder and offer suitable treatment. A healthcare provider may do the following to determine whether you have DSPD:
- Discuss Your Symptoms. The doctor will talk to you about your sleep habits and the problems you have noticed.
- Examine Your Sleep Diary. It is recommended to keep track of your sleep schedule at least one or two weeks prior to your visit to the doctor—write down the time you go to bed and wake up as well as any symptoms you may have during the day.
- Order a sleep study. In some cases, it may be necessary to undergo polysomnography – this test is usually carried out in a special facility where you spend a night hooked up to the equipment that records your brain activity, breathing, heart rate, blood oxygen levels, and movement during sleep.
Treatment Options for Delayed Sleep Phase Disorder
Fortunately, there are several therapies you can try to restore your sleep cycle and manage DSPD:
- Light Therapy. Also known as phototherapy, this treatment involves exposure to bright light shortly after waking up—it is believed that light affects the internal clock of the individual, helping them to feel more alert during the day and fall asleep faster at night.
- Melatonin Supplements. Melatonin is a hormone produced by our bodies naturally – it controls the sleep-wake cycle. Your doctor may prescribe melatonin pills to be taken in the evening to advance the sleep schedule.
- Sleep Hygiene. It is essential to create a healthy sleep routine—build a consistent schedule (wake up and go to bed at the same time, avoid naps during the day), limit screen time, especially in the evening, make your bedroom comfortable, and reduce caffeine and alcohol intake.
Tips for Managing Delayed Sleep Phase Disorder
In addition to the therapies listed above, you may want to implement these practices in your daily life:
- Stay on Schedule. While it may be tempting to sleep in on the weekend to “catch up” on sleep, sticking to the same hours for waking up and going to bed will be beneficial in the long run.
- Avoid triggers. Do not drink coffee in the second half of the day, stop using electronic devices at least one hour before bedtime, and cut out loud noise and bright lights in your bedroom.
- Spend Time Outside. Exposure to natural sunlight can be as helpful as light therapy—if you have an opportunity to go for a walk early in the morning, do so.
