What is delayed sleep phase syndrome and is it temporary?”
Delayed sleep-phase syndrome (DSPS), also known as delayed sleep-phase disorder (DSPD) or delayed sleep-phase type (DSPT), is a circadian rhythm sleep disorder, a chronic disorder of the timing of sleep, peak period of alertness, core body temperature, hormonal and other daily rhythms relative to societal norms. People with DSPS tend to fall asleep some hours after midnight and have difficulty waking up in the morning. Often, people with the disorder report that they cannot sleep until early morning, but they fall asleep at about the same time every “night”, no matter what time they go to bed. Unless they have another sleep disorder such as sleep apnea in addition to DSPS, patients can sleep well and have a normal need for sleep. Therefore, they find it very difficult to wake up in time for a typical school or work day. If, however, they are allowed to follow their own schedule, e.g. sleeping from 4 a.m. to noon, they sleep soundly, awaken spontaneously, and do not feel sleepy again un
People with DSPS tend to fall asleep at very late times, and also have difficulty waking up in time for school or work which begins in the morning. Often, DSP individuals report that they cannot sleep until early morning. Unlike insomniacs, however, they fall asleep at about the same time every night, no matter what time they go to bed. People with DSPS have at least a normal – and often much greater than normal – ability to sleep during the morning, and sometimes in the afternoon as well. In contrast, those with chronic insomnia do not find it much easier to sleep during the morning than at night..
