Human's sleeping cycles are tightly regulated by a series of circadian processes working in tandem, allowing for the experience of moments of consolidated sleep during the night and a long wakeful moment during the day. Among these physiological characteristics, the sleep-wake propensity can also be considered one of the daily rhythms regulated by the biological clock system. These biological clocks control processes that fluctuate daily (e.g., body temperature, alertness, hormone secretion), generating circadian rhythms. Humans, like most living organisms, have various biological rhythms. Delayed sleep phase disorder, advanced sleep phase disorder, non-24-hour sleep–wake disorder and irregular sleep–wake rhythm disorder represents the four main types of CRSD. These occurrences often lead to recurring instances of disturbed rest, where individuals affected by the disorder are unable to go to sleep and awaken at "normal" times for work, school, and other social obligations. As a result of this mismatch, those affected by circadian rhythm sleep disorders have a tendency to fall asleep at unconventional time points in the day. CRSDs arise from a persistent pattern of sleep/wake disturbances that can be caused either by dysfunction in one's biological clock system, or by misalignment between one's endogenous oscillator and externally imposed cues. Medical condition Circadian rhythm sleep disorderĬircadian rhythm sleep disorders ( CRSD), also known as circadian rhythm sleep-wake disorders ( CRSWD), are a family of sleep disorders which affect the timing of sleep. ![]()
