Circadian rythim

Circadian rhythms include some of the physical, mental, and behavioral changes an organism experiences over a 24-hour cycle. Light and dark have the biggest influence on circadian rhythms, but food intake, stress, physical activity, social environment, and temperature also affect them. Most living things have circadian rhythms, including animals, plants, and microorganisms. In humans, nearly every tissue and organ has its own circadian rhythm, and collectively they are tuned to the daily cycle of day and night. Circadian rhythms influence important functions in the human body, such as: Sleep patterns Hormone release Appetite and digestion Temperature
