In brief: Circadian disorder
Delayed sleep phase syndrome (dsps) is partly a genetic condition that results in the delayed timing of sleep with respect to the signal generated by the endogenous biological clock.
People with dsps cannot fall asleep until very late at night and then sleep late into the day. Moving one's wake-up time earlier by increments each day, evening melatonin, or morning bright light can ameliorate dsps.
