How does red light therapy work?
How do natural wavelengths of red and near-infrared light lead to these positive biological effects in your body?
All living things need to make ATP (adenosine triphosphate) cellular energy to function and survive, and nearly all living things rely on natural light to power this process in our cells every day. Red and near-infrared wavelengths of natural light stimulate the mitochondria in your cells, the powerhouses responsible for taking light, oxygen, and the food we eat—and turning it into usable energy for our bodies through the process of cellular respiration.
Natural red and near-infrared light also helps promote antioxidant production, which plays a central role in reducing the oxidative stress associated with cell injury and things like muscle fatigue, joint pain and inflammation. Antioxidants also increase the production of heat proteins—special enzymes that help protect cells from stress and early death.
