And the therapists working since the 1970s with John Ott's light therapy contributions continue working in the Santa Barbara, California area in modifying and expanding the therapeutic use of color and light. This work includes the use of full spectrum lighting and the use of lights and colored gels applied to the body's points. Treatment is applied preventively and to neutralize imbalances before they develop into an illness, and to rid illnesses that have already taken hold. Dr. Frtiz-Albert Popp, the father of biophoton therapy, discovered in the 1930s that normal living cells emit a steady stream of photons, or quanta of light radiation. He proved that living cells pass on biological information through photons through the language of light.
Cells communicate bio-information via the medium of light.
Light is a combination of the colors of the rainbow. In this way, the therapy is similar to acupuncture without the needles, utilizing still meridians and energy channels to affect bodily functions. The hypothalamus controls through the pituitary gland the bodily functions influenced by light. It is energized by external light that is transformed into electrical impulses by the eyes' photoreceptors. This light transmits instructions to the pituitary, which controls the endocrine system.
