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 rhythms are endogenous, near-24-hour biological rhythms that are synchronized to the 24-hour light-dark cycle. To maintain entrainment, the endogenous rhythm must be reset to the 24-hour clock time daily. The timing of actual sleep and the circadian rhythm sleep-wake propensity should...
Did you ever notice that you feel sleepy around the same time every day? Constantly running in the background of your brain and body, the circadian rhythm is a built-in 24-hour clock. It guides your body as to when you should be feeling sleepy, as well a
The daily sleep/wake cycle is influenced by two separate processes: (1) the endogenous biological clock that drives the circadian rhythm of sleep/wake cycle (Process C, for “circadian”) and (2) a homeostatic component (Process S, for “sleep”) that influences “sleep propensity”, a stat...
