The radiation plate of the infrared treatment lamp is coated with a proprietary mineral formula composed of 33 elements. When the board is activated by the built-in electric heating element, it will emit a specific electromagnetic wave band with a wavelength range of 2 µm to 22 µm and a radiation intensity of 25 mw/mm2. It works by increasing the local circulation of blood, lymph and nervous system activity. Infrared treatment lamps do not need gel or electrical stimulants, and can be used through clothes or directly on the skin. It is effective when deep heating of human tissue is required. The beneficial effects include reducing joint stiffness, increasing vasodilation, relieving muscle spasms and reducing pain caused by ligament sprains and strains.
