The Healthy Wave Mat 5 Therapy Far Infrared PEMF Belt is a specialty designed mat in the form of a belt which is worn around the torso. It easily wraps and forms around your body and can be fastened up to keep it in place. The total length of the belt is 53 inches with 5 lbs of pure crushed amethyst; this length allows it to easily fit around the majority of people. You can wear it while sitting down allowing use of it while performing office work or sitting on a couch. The Healthy Wave Mat Amethyst with Photon, PEMF and far infrared belt can be worn around your lower back, midsection or chest for targeted relief. The advantage of the belt design over the traditional mat is you can target 360 degrees around a specific area which maximizes the effectiveness of the far infrared heat, photon and PEMF.
