The light triggers 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.
Research shows that certain wavelengths of light within the red and infrared bands can be beneficial to living tissue. While other research examines the use of different intensities of light to determine appropriate levels. Dynamic Medical Center research has produced a clear determination of what works best and why.
Infrared Light Energy
Red light therapy (RLT) uses red low-level wavelengths of visible light on the skin and body which can result in many different benefits, including temporary relaxation of muscles, temporary relief from muscle spasms, etc.
Nitric oxide is released 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.
Vasodilation Significantly Improves Blood Flow
Vasodilation is a technique that improves blood flow and helps promote positive change in patients who suffer from chronic pain, numbness, or tingling.
It has been shown to lessen the pain and help nerves to begin carrying sensations again.
This technique is most often used by those with peripheral artery disease (PAD) and diabetes mellitus.
Studies show that the procedure significantly improves blood flow by releasing diabetes-related blockages in the arms and legs.
