From the Guidelines
To reduce the risk of relapse in Delayed Sleep Phase Syndrome (DSPS) and improve long-term treatment outcomes, a combination of light therapy, melatonin supplementation, and cognitive behavioral therapy (CBT) is recommended, with a focus on maintaining a consistent sleep-wake schedule and avoiding bright light in the evening. The most effective approach to managing DSPS involves a multi-faceted strategy that incorporates light therapy, melatonin supplementation, and CBT, as supported by the American Academy of Sleep Medicine clinical practice guideline 1.
Key Components of DSPS Management
- Light Therapy: Use a 10,000 lux light box for 30-60 minutes immediately upon waking, and avoid bright light in the evening, especially blue light from screens, as it can suppress melatonin secretion and phase shift circadian timing 1.
- Melatonin Supplementation: Take 0.5-3mg of melatonin 2-3 hours before the desired bedtime, as it can help phase shift circadian rhythms and promote sleep, with optimal dosing and timing being crucial for effectiveness 1.
- Cognitive Behavioral Therapy (CBT): Address unhelpful thoughts and behaviors around sleep through CBT, which can provide additional structure and motivational enhancement to light therapy, leading to more robust effects on sleep timing and measures of sleep disturbance 1.
- Lifestyle Factors: Exercise regularly, but not within 3 hours of bedtime, avoid caffeine after noon, limit alcohol, and create a cool, dark, quiet sleep environment to support sleep and circadian rhythm regulation.
Implementation and Consistency
Gradually shift the sleep schedule by moving bedtime 15 minutes earlier every few days until reaching the target time, and prioritize consistency in the sleep-wake schedule, even on weekends, to minimize the risk of relapse 1. By incorporating these strategies, individuals with DSPS can effectively manage their condition, reduce the risk of relapse, and improve long-term treatment outcomes, ultimately enhancing their overall quality of life.

Strategies to Reduce Relapse Risk in DSPS
To reduce the risk of relapse in Delayed Sleep Phase Syndrome (DSPS) and improve long-term treatment outcomes, several strategies can be employed:
- Gradual advancement of rise times: This approach has been shown to produce a phase advance during short-term interventions, irrespective of treatment condition 2, 3.
- Bright light therapy: Combined with melatonin, bright light therapy can help maintain an advanced sleep phase over time 2, 3.
- Melatonin administration: Melatonin has been found to have a sleep-promoting and entraining action when taken in the evening, and can be an effective treatment option for DSPS 4, 5, 6.
- Chronotherapy: This behavioral technique involves systematically delaying sleep time and can be used to treat DSPS 4, 5.
- Behavioral strategies: Additional strategies, such as establishing a consistent sleep schedule and creating a sleep-conducive environment, can also be helpful in managing DSPS 5.
Long-term Treatment Outcomes
Long-term treatment with bright light and melatonin can help maintain positive effects over time, including improved subjective daytime sleepiness, fatigue, and cognitive function 2, 3. However, relapse can occur after treatment is stopped, highlighting the importance of ongoing treatment and management strategies 6. Factors such as the timing of sleep and wake times, as well as sleep duration, can influence the likelihood of relapse 6.
