Red light is one of the wavelengths of sunlight (660 nm) and near-infrared light is imperceptible (850 nm). A red light device radiates red light and near-infrared light from close range, penetrating to the cellular level and bringing numerous health benefits.
The effects are based on the principle that most wavelengths of light, such as ultraviolet and blue, are absorbed by the skin and do not pass beyond the surface layers. Red light and near-infrared penetrate beyond the layers of skin into the mitochondria of cells – the parts that are responsible for cellular respiration. Cellular energy production (ATP) is activated when the cells receive more nourishment and the body functions more efficiently. Red light therapy is a completely harmless form of therapy that does not radiate hazardous UV rays or excess heat. Find out more about red light treatment.
