What is Far-Infrared Rays?
Sun rays can be divided into visible and invisible lights. Generally, visible light is composed of seven colors, which are the rainbow colours: red, orange, yellow, green, blue, indigo and purple.
An infrared ray is a type invisible light with wavelengths ranging from 0.75 to 1000 millimeters. Depending on the wavelength, the infrared ray can be roughly divided into near- infrared ray, mid-infrared ray, and far infrared ray.
Far-infrared ray with wavelengths ranging from 4 to 14 millimeters are beneficial to humans. Its energy and resonances resemblance to that of living tissues, and therefore, is called “reproductive light”. This reproductive light can activate and stimulate natural growth of cells in both animals and plants.
