Understanding Red Light Therapy

What is red light therapy?

Red light therapy, also known as photobiomodulation or low-level laser therapy, is a non-invasive treatment method that uses specific wavelengths of red and near-infrared light to stimulate healing and provide various health benefits. These wavelengths of light penetrate deep into the tissues of the body, promoting cellular rejuvenation and healing.

How does red light therapy work?

Red light therapy works by activating biological processes within the body at a cellular level. When exposed to red and near-infrared light, the mitochondria within cells absorb the light energy, which then leads to an increase in the production of adenosine triphosphate (ATP). ATP is the energy source that cells need to perform their functions and repair any damage.

This increase in ATP production is thought to stimulate various processes within the body, such as promoting collagen synthesis, reducing inflammation, improving blood circulation, and enhancing cellular regeneration.
