How does red light therapy work?

Red light therapy works by using low-wavelength red and infrared light to penetrate the skin and affect cellular processes. This type of light therapy is known for its ability to stimulate the mitochondria in our cells, often referred to as the cell's powerhouse. The light stimulates cytochrome c oxidase, a key enzyme in mitochondria, enhancing mitochondrial function and boosting cellular energy production. This increased energy can lead to improved cell vitality, faster healing, and reduced inflammation 1 2.

Additionally, red light therapy is thought to promote the release of nitric oxide, a signaling molecule that aids in vasodilation, improves blood circulation, enhances oxygen delivery, and facilitates better nutrient absorption on a cellular level. These processes contribute to its potential benefits, such as increased collagen production, reduced inflammation, and accelerated healing of cuts and abrasions 3 4. Originally discovered by NASA, the therapy has been extensively researched for its various health benefits 5.
