Circadian rhythms are the biological clocks in humans and other organisms that run on a 24-hour period, which are reset by the sun’s light/dark cycle. They control many behavioral and physiological processes in our bodies and are strongly influenced by environmental factors such as light, noise, nutrition, sleep, temperature, and social cues. These environmental factors are fed into a complicated system of molecular feedback loops, which impact the circadian rhythm.
