	'''Delayed sleep-wake phase disorder''' ('''DSWPD'''), historically called '''delayed sleep phase syndrome''' ('''DSPS''') or '''delayed sleep phase disorder''' ('''DSPD'''), is a [[circadian rhythm sleep-wake disorder]] in which a person’s major sleep period occurs substantially later than desired or required. People with DSWPD often cannot fall asleep until very late at night or early morning, and they have great difficulty waking at conventional school, work, or social times.
