DESC: What we do is simple. We feature products with deep penetrating heat and Negative Ion technology. Thermal heat as emitted by the Sun comes to us as heat-producing sunlight some that we can see and some that we can only feel. This is the warmth we feel penetrating our skin when standing in sunlight and the same warmth we recognize by its absence when walking in the shade. When heat penetrates through the skin into muscular tissue and ligaments it transforms from light energy into heat energy. The thermal effect can temporarily improve local blood circulation and therefore promote healing and wellness. Our mission at Therasage is to introduce this technology to you an exciting natural and healthy technology of both deep penetrating heat as well as the beneficial enhancement of Negative Ion therapy. The fibers of TheraDesign Shoulder Cover are impregnated with a special bio-ceramic formula that emits and reflects natural far infrared rays deep into the muscles tendons and ligaments of the shoulder area.
