When delivered within the optimal wave lengths and energy levels, red and near infrared light protect your body's cells from nitric oxide damage, which can otherwise stop the cells production of ATP when you're stressed or ill. Red light photons allow your cells to continue utilizing oxygen effectively by minimizing the absorption of nitric oxide. Only red light therapy can reach all the way into the mitochondria to stimulate healing and regeneration to help improve your appearance, performance, and overall well-being.
