The word Laser is an acronym for Light Amplification by Stimulation of Emission of Radiation, which accurately describes how the light is organized as it comes out of the optical assembly diode.
The word “radiation” in our context means it “radiates” or “emits” light, and because of its wavelength of 905 namometers, it’s considered therapeutic and completely safe. In every day situations light from light bulbs spreads out rapidly in all directions, but with laser technology it coheres the light in a narrow beam. So, because the frequency used by Cold Laser Therapy devices is between 600 and 1000 namometers, this invisible light has the ability to remain cold while it penetrates below the surface of the skin. Here it floods the tissue with photon energy that the body uses to heal damaged and painful tissue.
What is remarkable about this form of therapy is that we do not usually feel any kind of sensation while it’s working on or in the body. It truly is painless and non-invasive while getting good results!
There have been numerous scientific studies and are many research articles that discuss different aspects of Low Laser Light Therapy (LLLT), each with their own unique perspective, however the simple answer is through photonic absorption, laser light energy converts into chemical energy which initiates a cascade of events at a cellular level. Healing lasers are often termed low level lasers, cold lasers, or soft lasers. This defines them as lower powered or noncutting lasers.
• LLLT promotes healing in many conditions because it penetrates the skin, increases the ATP and activates enzymes in the targeted cells.
• Growth factor response within the cells and tissue as a result of increased ATP and protein synthesis.
• Improved cell proliferation.
• Pain relief as a result of increased endorphin release.
• Strengthening the immune system response via increasing levels of lymphocyte activity.
