    natural, internal processes regulating sleep-wake cycles every 24 hours

    Circadian rhythms are natural, internal processes that regulate the sleep-wake cycle and repeat roughly every 24 hours. These rhythms are driven by the body's "biological clock," which is influenced by external cues like light and temperature, and they play a crucial role in determining sleep patterns, feeding behavior, hormone release, and other bodily functions.
