Delayed Sleep Phase Syndrome: What It Is and How to Manage It
When dealing with delayed sleep phase syndrome, a sleep‑wake disorder where a person's internal clock runs later than the socially desired schedule. Also known as DSPS, it often shows up as difficulty falling asleep before early morning hours and trouble waking up for work or school. This condition delayed sleep phase syndrome encompasses a misaligned circadian rhythm, the 24‑hour biological cycle that regulates sleep, hormone release, and body temperature. Disruption of the rhythm can be triggered by genetics, lifestyle, or exposure to artificial light at night. Many find that melatonin, the hormone that signals darkness to the brain, is released too late, further pushing bedtime. Common strategies to reset the clock include timed light therapy, which supplies bright light in the morning to advance the rhythm, and strict sleep hygiene practices such as limiting screens, keeping a cool bedroom, and maintaining a consistent wake‑time.
How Medications and Daily Habits Influence the Clock
Beyond light and hormone tricks, everyday substances can tip the balance of the internal clock. Stimulants like caffeine or certain antihistamines can delay melatonin release, making it harder for someone with DSPS to feel sleepy at night. On the flip side, some prescription meds—particularly those that affect dopamine or serotonin pathways—may unintentionally improve sleep onset for some users. Our collection below includes detailed comparisons of drugs such as trihexyphenidyl, fexofenadine, and various corticosteroids, each with notes on how they might impact sleep quality or timing.
