This is the rechargeable device that produces safe infrared heat over a wide area to stimulate blood circulation, relieve swelling in joints, and loosen tight muscles. Using technology originally developed by NASA, the infrared light from its 72 medical-grade LEDs (68 infrared and four red) penetrates deep into tissue for lasting relief from muscle aches. A study at Children’s Hospital of Wisconsin in Milwaukee confirmed the LED technology reduced painful inflammation by up to 37%. More effective than heating pads that only treat just below the skin’s surface, the lightweight, triangular wand is easy to move on the body and begins to relieve pain in as few as three treatments. Recharges via USB or plugs into AC with included cables. 7 1/2" L x 3" W x 1 1/2" D. (10 oz.)
