Why some people feel a little cold at the moment they put on the far infrared clothes?
When the far infrared material in the clothes touches human skin, it will first absorb the heat in the body surface, and then reflect and emit far infrared. Some people are sensitive to far infrared and will feel a bit cold at the moment they put on far infrared clothes. However, the feel does not last long. Soon they will feel warm when the capillary blood vessels expand and the blood flow speeds up.
