Advanced sleep phase disorder is a circadian rhythm sleep-wake disorder in which a person's internal clock is shifted earlier than the conventional day, causing them to fall asleep and wake up much earlier than desired. Affected individuals may feel sleepy in the early evening and wake in the very early morning, which can interfere with social, family, and work schedules even though total sleep time may be normal. The condition reflects a misalignment between the body's circadian timing and the desired or socially expected sleep schedule, and it is studied alongside other circadian rhythm disorders that involve shifts in sleep timing. Within Sleep And Sleep Disorder Research, advanced sleep phase disorder sits among the broader study of circadian rhythm sleep-wake disorders. Related research includes work on the intersection of cultural factors and genetics in the prevalence of delayed sleep phase syndrome, a counterpart disorder involving a later-than-normal sleep schedule, and an exploration of the endocannabinoid system in circadian rhythms and sleep regulation. Together these studies illuminate how circadian timing governs the sleep-wake cycle. This page gathers peer-reviewed, open-access research relevant to circadian rhythm sleep disorders, including advanced sleep phase disorder.
