[Far Infrared Discussion] Effects on Human Skin

Introducing the effects of near-infrared and far-infrared on human skin!

AMK Co., Ltd. is a company that handles industrial far-infrared heaters, heating devices, and drying equipment. When infrared radiation is emitted to the skin, the reflectivity is high for visible light (up to 0.78μ) and near-infrared (0.78 to 2.0μ), while the transmittance shows that near-infrared penetrates and is absorbed about 20% up to 1mm deep. In other words, near-infrared is characterized by high reflectivity and transmittance with respect to human skin. When the wavelength exceeds 2μ, the reflectivity decreases and the absorption rate increases. Long-wavelength infrared has a low reflectivity, so most is absorbed at a very shallow depth in the skin. Since the temperature sensing part of the skin is often located within 0.3mm, far-infrared is mostly absorbed near the skin's surface, making it feel warm. When the temperature sensing part of the skin feels warm from near-infrared, the skin may be heated to the point of stinging. *For more details, please refer to the catalog or feel free to contact us.*
