Whether you're feeling hungry at meal times, feeling sleepy during late night hours, or feeling awake every morning...all of these are normal and natural behavior of all living things.

The mechanism that controls these physiological activities of the body is called the “Circadian rhythm”. It is also known as the “biological clock” or “body clock”.
