Red and infrared light
Red and infrared light support mitochondrial function and skin resilience.
Strong consensus“the red spectrum of light penetrates into the mitochondria kicks nitric oxide off and then the electrons can flow through”
Red light exposure
Red light exposure supports skin and mitochondrial health, and helps prepare the body for sun exposure.
Strong consensusFor mitochondrial health and light exposure.
The strongest voice
“42 percent of the light from the sun is red light and this is really important for counteracting all the blue light”

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.”
