Circadian rhythms are regulated by both the suprachiasmatic nucleus and patterns of light and dark. The suprachiasmatic nucleus is a small structure in the brain that acts as the body's master clock, regulating the timing of various physiological processes. However, the rhythms can be affected and even reset by exposure to patterns of light and dark, as the body uses these cues to help synchronize its internal clock with the external environment.
