The effects are photochemical, just like photosynthesis in plants. When the correct parameters are used, light reduces oxidative stress and increases cellular energy (ATP). This in turn improves cell metabolism and reduces inflammation.
PBM Therapy appears too good to be true as it has many applications, but really it does just one thing and it does it very well. It reduces oxidative stress. Oxidative stress is essentially an imbalance between the production of free radicals and the ability of the body to counteract or detoxify their harmful effects through neutralization by antioxidants, is critical in helping the body recover. Oxidative stress is accepted as the underlying trigger for most diseases and degenerative conditions. It is also a component in the inflammatory phase of acute and chronic injuries. Extensive research during last two decades has revealed oxidative stress can lead to chronic inflammation, which in turn contributes to chronic diseases including cancer, diabetes, cardiovascular disease, neurological disorders and pulmonary diseases.
