Circadian rhythms (circadian clock) are the physical, mental, and behavioral changes that an organism experiences over a 24-hour cycle, affecting the release of hormones and overall health.
The circadian rhythms are controlled by the circadian clock or biological clock that commands our brain to release hormones to control our activity in several days.
