It is widely used in communication, detection and medical treatment. Commonly known as infrared light. Infrared rays have strong penetrating power to human skin and subcutaneous tissue. The primary effect of external infrared radiation on human body is to raise the temperature of skin and subcutaneous tissue, promote blood circulation and metabolism, and promote human health. The thermal effect, anti-inflammatory effect and promoting regeneration of infrared physiotherapy on tissues have been clinically confirmed.
