Thermal Design Power (TDP) lamps are far infrared heating devices used to accelerate natural healing processes. Far infrared (below visible light spectrum) emissions are thought to penetrate deeply into the body, increasing microcirculation and thus delivering more oxygen and nutrients to injured cells while eliminating cellular waste. They are increasingly used in acupuncture clinics in China and throughout the world to support acupuncture treatment or to replace moxibustion where the patient or practitioner is sensitive to moxa smoke and/or there is inadequate ventilation. The lamp which is used ar a distance from the skin (approximately twelve inches) deeply heats the area being treated without causing burning. It is commonly used on the upper or lower abdomen or back, in combination with needling, for cold and deficient patterns, or on painful areas in the case of injuries, bi syndrome (rheumatic and arthritic conditions) etc.
