What is Red Light Therapy?

Red Light Therapy or RLT, is a form of light therapy that helps heal skin, muscle tissue, joints as well as other parts of the body.

It exposes the body to high powered red and/or near-infrared light. Infrared light produces a type of energy that your eyes can’t see, but your body can sense as heat. Red light is very similar to infrared light with the difference that your eyes can see it.

Other terms used for RLT include Low-level laser therapy (LLLT), low-power laser therapy (LPLT), and lastly photobiomodulation (PBM).

How does red light work?

You expose your naked skin to a RLT device, and the mitochondria of your body’s cells absorb it and turn it into more energy. 

Many experts think RLT helps the cells to repair themselves and improve overall health especially in skin and muscle tissue.

RLT uses very low levels of heat therefore it does not hurt or burn the skin.

Does red light treatments have risks?

Red Light is considered a safe form of therapy. There are no specific sets of rules on how much light and for how long every treatment should go for as it really depends on the device and the condition is used for. 

Generally too much light exposure could cause tissue damage and too little lightexposure might not be enough to get the benefits.
