One of the physiological effects of LED red light enhances cell metabolism
Red light has a photochemical effect on the organism, and red light can stimulate the sympathetic nervous system, representing excitement and tension, so that it produces corresponding biological effects and therapeutic effects.
Mitochondria in cells have the greatest absorption of red light. If human cells are compared to a car, mitochondria are the engine. Mitochondria combine the organic matter and oxygen in the cell, convert it into carbon dioxide and water through a complex process, and release the chemicals in the organic matter for the cell to use. So mitochondria are energy transmitters in cells. In addition, mitochondria are also involved in processes such as cell differentiation, cell information transmission and apoptosis, and have the ability to regulate cell growth and cell cycle.
Mitochondria are units that directly use oxygen to produce energy, and more than 90% of the oxygen inhaled in the body is consumed by mitochondria.
The main function of mitochondria is to carry out oxidative phosphorylation, synthesize ATP (adenosine triphosphate), and directly provide energy for cell life activities. Cytochrome oxidase in mitochondria is a photon receptor. After red light irradiation, it can promote synthesis, and the generated ATP is used for cell metabolism, thereby maintaining cell function. Experiments show that red light irradiation for 20min can increase the ATP of HeLa cells by 190%. Jia Danbing team found that red light irradiation has the ability to increase ATP.
