Infrared light is the sun’s healthy warmth and is invisible to the naked eye. Its rays go beyond visible light and the colors of the rainbow. Therefore, we can only perceive infrared light in the form of radiant heat. This radiant heat is really beneficial to the body and takes action deeper in the body than the convection of warm air, for example. This means that infrared heat is the most efficient way to warm your body. Infrared heat also stimulates the production of endorphins in the body. This hormone also called a natural painkiller, relieves pain in the muscles and joints (such as in the event of a sprain, rheumatism, and arthritis), and removes muscle tension, swelling, and stiffness. The infrared heaters by Alpha Wellness Sensations guarantee safety, sustainability, efficiency, and comfort.
