Learn how to understand circadian rhythm, the body's 24-hour clock that regulates its sleep/wake cycle, with articles and resources from Sleep Cycle.
sleep–wake cycle is the most obvious example of a circadian process, as it occurs with a consistent 24-h rhythm and can be shifted according to environmental cues. The body’s circadian clock system maintains these 24-h rhythms in physiological functions, including the sleep–wake cycle, and...
Circadian clock genes have emerged as important genetic components in multiple aspects of sleep and wake regulation.doi:10.1016/B978-008045046-9.01603-XA.D. LaposkyF.W. Turekencyclopedia of neuroscienceLaposky AD, Turek FW. Circadian genes and the sleep-wake cycle. In: Squire LR, editor. ...
The sleep–wake homeostat works in concert with the circadian rhythm. REM sleep REM sleep, which occurs primarily during the latter half of a sleep cycle (primarily owing to the influence of process C), is associated with the highest brain activity during sleep and with dreaming. During REM ...

Sleep-wake cycle, which consists of roughly 8 hours of nocturnal sleep and 16 hours of daytime wakefulness, is controlled by 2 internal influences: sleephomeostasisand circadian rhythm. The period of circadian rhythms is about 24 hours in a normal light-dark cycle and is synchronized to the ext...
the sleep-wake cycle, which typically aligns to the external light-dark cycle. In normally entrained individuals, the circadian rhythm interacts with the homeostatic sleep drive in an opposing manner to provide consolidated wakefulness during the daytime hours and continuous sleep during the night [18...
WASHINGTON, Jan. 29 (Xinhua) -- An American study shows that a disorder in sleep and wake cycle might be early signs for Alzheimer's disease. The research at Washington University School of Medicine in St. Louis has indicated that the circadian rhythm disruption occurs much earlier in people...
