Infrared light therapy
Infrared light therapy is widely valued for supporting mitochondria and relaxation.
Strong consensus“infrared light which can penetrate 8cm into the body can help to clear this out of the way so that your mitochondria can carry on making ATP and water”
Infrared exposure
Infrared exposure helps support healthy blood flow and cellular energy production.
Strong consensus“The main things are sunlight exposure, infrared light, anything that's going to build charge in your body is going to help build the structured water and that’s going to prevent this clotting response.”
