Far Infrared Radiation

Near infrared is associated with skin benefits, collagen production, wound healing, localized muscle recovery, and inflammation reduction. The source divides infrared light into near, mid, and far infrared wavelengths. Wavelength temperature and length are inversely related: hotter wavelengths are shorter and harder to drive into body tissue, while cooler wavelengths are longer and penetrate more easily. Far infrared, being the longest and coolest end of the infrared spectrum, achieves the deepest tissue penetration of any infrared band. Infrared's ability to penetrate deeper into tissue is the proposed mechanism behind the distinct physiological effects users report compared to traditional steam or wood-fired saunas. Far infrared is the most extensively discussed wavelength and is linked to heart health, blood flow, circulation, blood pressure, core temperature, sweating, detoxification, and immune effects. Mid infrared is presented as especially relevant for joints, tissues, inflammation, athletic recovery, and performance-related needs. Sunlighten has focused its engineering on maximizing the proportion of far infrared wavelengths delivered per session to achieve the highest po…
