Circadian rhythms are biological processes that display an internal cycle of about 24 hours, influencing various physiological functions in living organisms. They regulate important behaviors such as sleep-wake cycles, hormone release, and metabolism. These rhythms help organisms adapt to the predictable day-night changes in their environment, promoting overall health and well-being. Disruption of circadian rhythms can lead to sleep disorders, metabolic issues, and other health problems. Understanding these rhythms is crucial for enhancing wellness and developing effective treatments in chronobiology.
