How LED Light Therapy Works

LED light therapy is a simple treatment for skin, recovery, inflammation, joint pain, sleep and a lot more. A red light therapy home device like our Photonstar use LEDs to shine red and near-infrared light on your body when you are doing treatment.
So what exactly is red light therapy? How does it work?

The Origins of Red Light Therapy
The positive health benefits of red light were first discovered in 1993 by NASA in an experiment using red LEDs to boost plant growth.

Researchers involved in NASA's plant experiments developed multiple small wounds while working with plants, and with the absence of gravity in space, astronauts' muscles and bones atrophy, and any wounds heal slowly. One serendipitous finding the experimenters noticed was that their wounds and other skin lesions healed significantly faster when they were exposed to red LED lights for hours on end. Since then, NASA has entered the field of medical phototherapy.

Increased Cellular Energy Levels

After years of research and discussion, the reason why light can make cells respond is that the granulocytes in cells absorb photon energy and convert its energy into adenosine triphosphate (ATP), which is the form of energy utilized by cells. The resulting ATP powers cellular metabolic processes; synthesizes DNA, RNA, proteins, enzymes, and other products needed to repair or regenerate cellular components; promote mitochondrial or cellular proliferation; and restore balance.

Light Therapy is Safe and Effective

Overall, light therapy can relieve pain and promote the repair of skin, nerves, bones, muscles, tendons, cartilage and ligaments. It is a non-invasive physical therapy with no side effects and deserves wide use.
