Delayed sleep phase syndrome (DSPS) is disorder of sleep timing. In this condition people have trouble timing their sleep around daily activities. Because their sleep is ambitious by their own internal clock, they tend to fall asleep at very late times and also have difficulty waking up in the morning.
Delayed sleep-phase syndrome (DSPS), also known as delayed sleep-phase disorder or delayed sleep-phase type (DSPT).
Definitions of Delayed sleep phase syndrome (DSPS)
- Delayed sleep phase syndrome (DSPS) is a disorder of sleep timing. People with DSPS tend to fall asleep at very late times, and will subsequently sleep later in the day having difficulty waking up in time for normal work, school, or social needs.
The Exact reason of DSPS is not known, DSPS results from a desynchronization between the patient's internal biological clock and the external environment. The reasons of DSPS are not related to jet lag, sleep-wake changes from working shifts or any other external factors.
The main complexity for patients with DSPS is carrying out early in the morning for school or work. A person of DSPS frequently fails courses in school or loses jobs, affecting them generally and compromising their health.
This symptom usually shows in childhood and young men and frequently vanishes in old age. DSPS can result in health and social impacts. People with DSPS feel most alert and say they function best and are most inspired in the evening and at night. DSPS patients cannot simply force themselves to sleep early.

- Depression may be present
- This sleep pattern has been present for 3 months
Treatment of DSPS
Most DSPS treatments are listening carefully on synchronizing the internal body rhythms with the demands of work, school and social activities. The treatment goal is to find those with DSPS to wake up at usual times feeling rested and prepared to go on with their days.
Bright Light Therapy
- In most cases Doctors advise bright light therapy, a treatment that relies on keeping a bright light that timed to turn on in the morning for 30 to 90 minutes at a patient's bedside. Bright light in the morning will help reset the body’s internal clock. Special light boxes need to be purchased for this treatment.
- Chronotherapy, attempts to reset the body's natural circadian rhythm, it also may be prescribed. In this therapy a DSPS patient goes to sleep later each night for many days in a row until the desired bedtime is reached, gradually adjusting the internal clock. Chronotherapy was first suggested by C.A. Czeisler and first used to treat DSPS in 1981.
Doctors normally recommend Vitamin B-12 and Melatonin to all of their DSPS patients. But, more research is needed to decide the effectiveness and potential side effects of each. To get More information Click Here.
