What does your circadian rhythm have to do with biological clock?

The circadian rhythm is a natural, internal process that regulates the sleep-wake cycle and other physiological functions over a roughly 24-hour period. It is often referred to as the body's biological clock, as it is influenced by external cues like light and temperature, helping to synchronize various biological processes. This rhythm plays a crucial role in determining sleep patterns, hormone release, and metabolism, ultimately affecting overall health and well-being. Disruptions to the circadian rhythm can lead to sleep disorders and other health issues.
