Red light Therapy was actually pioneered by NASA in the ’70s.

When they were sending astronauts to space after a short amount of time astronauts began to develop a sort of space sickness. NASA was baffled but they soon found out it was because they weren’t being exposed to sunlight.

Now every living thing on this planet has evolved from the beginning of time to use sunlight in some way or another from producing Vitamin D in your skin to plants and photosynthesis, and so do we.

It’s not like NASA could just go open a window in space and let the sunlight through or everything from x-ray radiation, gamma radiation, and Ultraviolet radiation would kill you.

So NASA started researching sunlight and they found red light was the one that we actually needed.
