Circadian rhythm sleep disorders happen when the circadian rhythm is not working correctly. They make people sleep and wake at times that are not normal, but these people usually have 8 hours of good sleep. These disorders affect other systems in the body, too, and not just sleep. Circadian rhythms also control appetite, body temperature rhythm and hormone cycles. Extrinsic causes such as jet lag can affect the female menstrual cycle (periods) in addition to the sleep.
