Significance of Circadian rhythm
Circadian rhythm is an internal biological process that influences various physiological functions in living organisms, following a roughly 24-hour cycle. This rhythm plays a crucial role in regulating the sleep-wake cycle, hormone levels, and metabolic activities, among others. Changes in environmental cues like light impact these rhythms, which can be disrupted by irregular lifestyle patterns. Overall, circadian rhythms are essential for maintaining health by governing daily fluctuations in physical, mental, and behavioral processes.
