Circadian Rhythm Sleep Disorders
Circadian rhythm sleep disorders all involve a problem in the timing of when a person sleeps and is awake. The human body has a master clock in a control center of the brain. This internal clock regulates the timing of body rhythms such as temperature and hormone levels. The primary circadian rhythm that this body clock controls is the sleep-wake cycle. The circadian clock functions in a cycle that lasts a little longer than 24 hours and is set mostly by visual cues of light and darkness. This keeps the clock synchronized to the 24-hour day. Other time cues, such as meal and exercise schedules, also can influence the clock’s timing. Circadian rhythms and their sensitivity to time cues may change as a person ages.
