Principles of Red Light Therapy Apparatus

A red light therapy instrument is a medical device that irradiates the human skin with red light to promote cell metabolism, enhance immunity, improve blood circulation, relieve pain and so on. Its principle mainly lies in utilizing the special wavelength and energy of red light to stimulate the metabolic activities of human cells, thus achieving the effects of treatment and health care.

The wavelength of red light generally ranges from 630 to 660 nanometers. The light of this wavelength can penetrate human skin and directly irradiate muscles, bones, joints and other parts, thus stimulating the metabolic activities of cells. Red light can promote the synthesis of ATP in cells, increase the energy supply of cells, and improve the immunity and antioxidant capacity of cells, thereby achieving the effects of treatment and health care.
