Circadian Rhythms

Circadian rhythms are the internal clocks that govern our 24-hour cycles of sleep, hormone release, and body temperature. These rhythms are controlled by genes and influenced by light exposure. Disrupting them through jet lag or shift work can affect health, mood, and cognitive function.
