First, a brief introduction . . . .

Our basic human nature is to seek light. The darkness usually represents danger and also with death itself, the ultimate destroyer. This love of

light and fear of darkness is not merely a matter of psychological mood or social training. As you lie out on the beach on a bright afternoon, the light from the

sun stimulates and energizes the body and the mind. In fact, light has a direct influence on the workings of the innermost part of the brain and our bones. For

instance, Rickets is a vitamin deficiency disorder caused by a lack of vitamin D. The prime source of vitamin D comes from the ultraviolet (UV) light in sunlight,

the same UV that tans our skin. The UV light generates vitamin D from chemicals in the skin called Sterols. One of these sterols, Ergosterol, is obtained from

vegetable oils in the diet. UV light helps the body produce vitamin D, but if over exposure occurs, it also can cause skin-cancer. If the body receives too little

UV light then the result is not only rickets but severe bone deformities, including women whose pelvic bones are so deformed by rickets that they frequently

die in childbirth.

If our ancestors had not received enough UV light from sun's energy, the human race probably would have become extinct. Throughout time,

humankind has learned to live with the Sun's UV light rays, adapting our skin coloration to provide enough UV light for the necessary production of

VitaminD, but to screen out the excess UV light that causes skin cancers.

Over time, the human has been able to adapt to the geographical and environmental limitations of life on this planet earth. A person's skin color

plays an important role in the amount of UV light one receives. The pigment that protects the body from excessive UV light is melanin, and it is present in every

human being; in our skin, our hair and the irises of our eyes. Fair skinned people have comparatively little melanin, but that which they do posses, darkens the

skin upon UV light exposure. In dark skinned people greater amounts of melanin are present in the body and consequently they are able to block most of the

incoming UV light and thus protect the body from the harmful effects of excessive UV light radiation.

The idea of using light to treat disease is not at all new. In 1876, Augustus J. Plesanton, a retired Civil War general, published The Influence of

the Blue Ray of Sunlight and the Blue Color of the Sky, in Developing Animal and Vegetable Life, in Arresting Disease, and Restoring Health in Acute and

Chronic Disorders to Human and Domestic Animals. In 1877, the RED and the BLUE Light an incredible book written by S. Pancoast, MD., was devoted to the

true science of Light, describing light and its rays as medicine showing that light is the original and sole source of all the physical and vital forces of nature;

and that light is nature's own remedy for disease.
