The 1998 Nobel Prize was awarded to scientists who discovered the relationship between near-infrared light (NIR), nitric oxide and increased circulation, ushering in a movement toward numerous, safe applications for LED phototherapy.
In LED phototherapy, both infrared and red light trigger the release of nitric oxide from blood vessels and red blood cells. Nitric oxide causes local vasodilation that lasts several hours after the therapy session has ended. Vasodilation improves blood flow. Improving blood flow lessens pain and helps nerves to begin to carry sensations again.
There are two main factors to maximize the benefits of LED phototherapy: the wavelength and intensity of light energy. While most devices have only LED red lights, our LED create specific frequencies of red and infrared lights.
During treatment, the infrared light energy releases nitric oxide from hemoglobin and endothelial cells. Nitric oxide is a signaling molecule that relaxes smooth muscle cells found in the arteries, veins, and lymph vessels. When these muscles relax, the vessels dilate, thus allowing increased circulation.
Many scientific studies have shown that light therapy is effective in improving nerve health. It works by increasing ATP (adenosine triphosphate) synthesis in the mitochondria, activating the electron transport system, and many other biochemical and biophysical reactions in the tissue.
Infrared light therapy to alleviate pain and improve circulation is based on decades of research that found that certain wavelengths of light within the red and infrared bands were very beneficial to living tissue.
