Sleeping Out of Sync: What You Need to Know About DSPD
Published
Did you know that between 7-16% of adolescents and young adults may experience Delayed Sleep Phase Disorder (DSPD), a condition where falling asleep and waking up align poorly with societal norms? This is the reality for individuals living with Delayed Sleep Phase Disorder (DSPD)—previously known as Delayed Sleep-Wake Phase Disorder (DSWPD)—a circadian rhythm sleep disorder where sleep-wake cycles are significantly delayed and which affects teenagers more than adults (who have a prevalence estimate of 1-3%).
DSPD isn’t just about being a “night owl”; it can affect daily responsibilities, relationships, and overall well-being. By understanding DSPD and its treatments, individuals can regain control over their sleep and improve their quality of life.
1. What is Delayed Sleep Phase Disorder?
DSPD is a sleep disorder characterized by a misalignment between an individual’s internal body clock and societal norms for sleep and wake times. Those with DSPD experience a delay of at least two hours in their sleep-wake cycle, which can make it challenging to fall asleep and wake up at desired times. Unlike typical night owls, individuals with DSPD often face significant daytime impairment due to this misalignment.
2. Recognizing the Symptoms
Common symptoms of DSPD include:
- Difficulty falling asleep at a conventional bedtime.
- Struggling to wake up at desired times.
- Excessive daytime sleepiness, which can make it difficult to maintain school or work obligations.
- Impaired concentration and cognitive function—sometimes leading to mental health issues such as depression and anxiety.
- Prolonged sleep inertia (grogginess upon waking).
3. Risk Factors and Causes
Several factors may contribute to the development of DSPD:
- Adolescents and young adults:Natural shifts in circadian rhythms during puberty make this group more susceptible.
- Genetic predisposition:A family history of DSPD can increase risk.
- Mental health conditions:Higher rates of depression and anxiety are associated with DSPD.
4. Treatment Options for DSPD
Managing DSPD often involves aligning the sleep-wake cycle with societal demands through tailored interventions:
- Chronotherapy:This method involves shifting sleep and wake times incrementally over days or weeks until they align with a desired schedule, requiring strict adherence to maintain effectiveness.
- Light therapy:A technique that involves exposure to bright, full-spectrum light in the morning, which can help reset the body’s internal clock and signal earlier wake times.
- Melatonin supplementation:By taking melatonin supplements in the early evening, individuals can encourage their body’s natural inclination to fall asleep earlier, helping to recalibrate the circadian rhythm.
But there are also simpler changes that can be made, such as:
- Keep a consistent bedtime routine: Do this even on weekends, to avoid shifting the internal clock further. It is one of the keys to having a good sleep hygiene.
- Use technology in a way that suits you: Blue light can delay melatonin secretion, which is connected to alertness. But studies show that this has little bearing on how long it takes to fall asleep. Instead, many people use their phone or computer to relieve stress—or sometimes just pass time until their body is ready to fall asleep.
- Avoid stimulants late in the day: Caffeine, nicotine, or intense exercise in the evening can make it harder to fall asleep earlier.
Each individual’s response to treatment varies, so consulting a healthcare professional is essential for a personalized approach.
5. Conclusion
DSPD is more than a late-night preference; it’s a challenging disorder that can disrupt lives. Understanding its causes and treatments can empower those affected to take meaningful steps toward better sleep. By utilizing tools like light therapy, melatonin, and personalized interventions, individuals with DSPD can reclaim their mornings and improve their overall well-being.
