The Science of Photo-bio-modulation (PBM)
For ideal health, all humans require regular exposure to light! A great example is Vitamin D which comes from sunlight. The sun’s rays include the more commonly known ultraviolet light (UV), but more than half of its output is infrared. When it comes to visible light, violet colored light contains the highest energy and red colored light the lowest energy from the visible light.
As mentioned above, this spectrum classifies each form of energy by nanometers and its effect on the human physique. Nanometers are a unit of length equivalent to a billionth of a meter, and they are used to measure the wavelength of light. Since we’re comparing red light to NIR light, it’s important to note their order on the spectrum.
- Red light is visible and is most effective for use on the surface of the skin. Red light occupies the “long end” of the visible spectrum with wavelengths of 630nm-700nm.
- NIR light is invisible and is effective for use on the surface of the skin as well as penetration of around 2 inches into the body. NIR light sits right next to red light on the electromagnetic spectrum at 800nm to 1000 nm.
The wavelength of NIR light is longer than the wavelength of red light, which allows NIR light to penetrate more deeply into the body. Thus, NIR light provides some similar, but somewhat different benefits than red light. The science behind these concepts has been around for centuries. Both benefits from red and NIR light have become available as the quality Red and NIR LED PBM devices from Benilight are introduced.
Red light and NIR light from LEDs are both natural, drug / chemical free, non-invasive, effortless, safe, and users have reported no adverse short or long term side effects. While both therapies are beneficial, the type you should choose depends on the outcome you desire. If you want to treat skin conditions on the surface, Red light LED session is focused and effective. If there is toxicity in the body or stronger metabolic effects are desired, an NIR session may be the better choice. An NIR session is a more holistic solution to wellness because it can provide skin rejuvenating benefits (like those of Red Light LED), but it can also help you burn calories, release toxins, increase blood flow, ease pain and put you in a state of utter relaxation. Therefore, Red and NIR combined LED PBM will be one the best choices of all kinds of PBM.
