Delayed Sleep Phase Syndrome

When dealing with Delayed Sleep Phase Syndrome, a circadian rhythm disorder that pushes bedtime and wake‑time later than the norm. Also known as DSPD, it often leads to insomnia, daytime sleepiness, and social‑work conflicts. The condition delayed sleep phase syndrome is tightly linked to the body's internal clock, or circadian rhythm, the roughly 24‑hour cycle that regulates sleep, hormone release, and metabolism. Disrupting this rhythm can throw sleep timing off by several hours.

Two tools most clinicians reach for are melatonin, a hormone supplement that signals darkness to the brain and helps shift the sleep window earlier and light therapy, exposure to bright light in the morning that advances the internal clock. When used together, they form the backbone of chronotherapy, a systematic schedule of light, dark, and melatonin designed to reset sleep timing. Research shows that a consistent morning light session of 30 minutes can advance sleep onset by up to an hour per week, while low‑dose melatonin taken 3‑5 hours before the desired bedtime reinforces that shift.

Beyond these core strategies, lifestyle tweaks matter. Limiting evening screen time, keeping a regular bedtime, and timing caffeine intake all influence the same circadian mechanisms that cause DSPD. People with shift‑work schedules or chronic jet lag often develop a secondary form of delayed sleep, so recognizing the overlap with shift‑work disorder, a condition where work hours conflict with the natural sleep‑wake cycle can guide more personalized interventions. For instance, a night‑shift nurse might benefit from a dim‑light environment during the day and a strategic melatonin dose before sleep.
