For many animals, systems of light are particularly important because their bodily functions are contingent on the secrecy to nature. behavioral patterns such as hibernation and breeding, are dictated by seasonal changes. people's reactions are often influenced in a similar fashion by light.

In his book, light medicine of the future, noted optometrist, Jacob Leiberman explains how light enters the body through the eyes. The pineal gland is located deep at the center of the brain, between the two hemispheres and behind and above the pituitary gland. Although it is the only the size of a pea, its functions are vast. It acts as the body's light meter, receiving light activated information, and then sending out hormonal messages that have a profound effect on the mind and the body. The powerful hormone melatonin, manufactured by the pineal gland in the eyes regulates the body's daily rhythm and functions. Light in effect, activates our biological clock.

Melatonin is released in response to darkness during the sleep cycle, without the influence of light on the body. Our rhythmic functions would be highly undisciplined clearly the son is the master Of all the rhythms
