A system and method for the light activation of healing processes uses a light source that is directed onto the body of a subject. The light source may generate monochromatic light and/or coherent light. The subject is positioned within a chamber having interior reflective surfaces that permit the reflection of photonic energy emitted from the body of the subject to be reflected back to the subject. The light source activates the photonic emission process. In an alternative embodiment, reflective surfaces may be brought into proximity or into direct contact with the subject and the light source directed onto the subject. The light source may be held in fixed position with respect to the subject or moved so as to be directed to an area of the subject. The light source may have a fixed intensity or varying intensity, such as by pulsing or modulating light source.
