Using technology developed by NASA to heal astronauts’ injuries, this device’s 60 LEDs produce safe infrared heat to stimulate blood circulation, relieve swelling, and loosen muscles in small areas of the body. A study at Children’s Hospital of Wisconsin in Milwaukee showed the LED technology reduced painful inflammation by up to 37%. Developed exclusively by Hammacher Schlemmer and unlike heating pads that only treat just below the skin’s surface, the LED light penetrates deep into tissue for lasting relief from muscle aches or arthritic inflammation. The device is placed 1/4" from the skin and begins to relieve pain in as few as three treatments. The lightweight, brush-shaped design is easy to move around the body and hold in place. Includes a travel bag. Plugs into AC. 7 1/2" L x 2 3/4" W x 1 1/4" D. (5 oz.)
