Light therapy works by delivering light energy to body tissues thus stimulating them on a cellular level. This stimulated tissue function enhances the body’s healing abilities through amplified cellular function. This principle is currently used in modern medicine to treat seasonal affective disorder, newborn jaundice, and psoriasis. New evidence is emerging on the substantial effects of light therapy on healing in various brain disorders.
Different wavelengths of light energy stimulate different tissues in different ways yielding the desired healing effect. This non-invasive technique, which yields a variety of physical and psychological benefits, is currently being used in cancer treatments through the different applications of “photodynamic light therapy”.
