Delayed Sleep Phase Syndrome – What You Need to Know

When you first encounter Delayed Sleep Phase Syndrome, a condition where your internal clock runs later than the typical schedule, making it hard to fall asleep at night and wake up in the morning. It’s also known as DSPS. This disorder is tightly linked to a shifted circadian rhythm, the 24‑hour biological cycle that regulates sleep, hormone release and body temperature. Because the rhythm is delayed, the body’s natural dip in alertness happens much later, so you feel most awake when most people are already in bed. A common way to reset that timing is by using melatonin, a hormone that signals darkness to the brain and helps shift the sleep window earlier. In addition, light therapy, exposure to bright light in the morning to advance the internal clock and solid sleep hygiene, practices like consistent bedtime, limited screen time, and a dark bedroom are essential tools for managing DSPS.

Why does the circadian rhythm matter so much? It controls the release of melatonin and a host of other hormones that tell your body when to wind down. When the rhythm stays delayed, melatonin peaks later, so you don’t feel sleepy until the early hours. Simple changes, such as stepping outside for natural sunlight within an hour of waking, can give your rhythm a strong cue. That cue works hand‑in‑hand with melatonin supplements, which act like a shortcut to tell your brain it’s nighttime earlier than it would on its own. Many people find that a low dose taken an hour before their desired bedtime nudges the clock forward without causing morning grogginess.

Light therapy is another powerful lever. Sitting in front of a 10,000‑lux box for 20‑30 minutes each morning forces the brain to register “daytime,” which pushes the internal clock earlier. The timing is crucial – too late in the day can actually delay the rhythm further. Pair this with strict sleep hygiene: keep the bedroom cool, block blue‑light from screens after dusk, and reserve the bed for sleep only. Over time, these habits reshape the rhythm, making it easier to fall asleep at a conventional hour and wake up refreshed.
