What are the benefits of 660-nanometer red light to the human body?

The light wave with a wavelength of 660nm is called the "light of life" in the golden band of the human body by the world medical community. It can penetrate human skin, fat, muscle, blood vessel wall and other tissues without damaging human tissue cells. The emitted laser power is 1-5MW, which belongs to low-energy laser. The irradiation density is far less than the damage threshold of the body and blood. During nasal laser irradiation, the laser penetrates the human body without causing any damage to the body. A large amount of laser energy penetrates the blood vessel wall and other tissues and is absorbed by blood, which has a good therapeutic effect.

Red light therapy should be a kind of physical therapy. Most of these cases promote local blood circulation and promote the absorption of inflammation.

Red light treatment uses physical and chemical means to filter out most of the red light, and then mainly uses the red light band, so as to achieve the purpose of treatment. Because red light is mainly absorbed by mitochondria, which is a necessary organelle for human energy supply, red light therapy is widely used in medicine.
