A system and method for a whole-body immersion bed or cabinet that permits the user to experience the therapy on their entire body at the same time. The therapy in its most basic form is a combination light, and sound therapy. Each therapy session includes a set of resonant frequencies and a set of beneficial light wavelengths applied to the user at the same time. The resonant frequencies are applied through specific pulses that are chosen based upon the condition that the therapy is attempting to treat. Additionally, the resonant frequencies may be applied through a frequency pulse generator. The frequency pulse generator is set to a pre-established set of frequencies that have been shown to be effective for treating each particular condition.
