“Red Light Therapy: An Innovative Option for Pain and Inflammation Treatment


Red light therapy, also known as low-level phototherapy or low-level laser therapy, has emerged as a promising option for the treatment of pain and inflammation in various medical conditions. This therapy utilizes wavelengths of red and near-infrared light to stimulate cellular repair and reduce inflammation in the body. In this article, we will explore the scientific foundations behind red light therapy and discuss its application in the treatment of pain and inflammation.

Scientific Foundations of Red Light Therapy

Red light therapy is based on the ability of light in the red and near-infrared spectrum to penetrate tissues and be absorbed by cells. The energy from the light is absorbed by chromophores, specific molecules in the cells that absorb light and convert it into chemical energy. One of the major chromophores in human cells is cytochrome c oxidase, a crucial enzyme in cellular energy production (ATP) and protein synthesis (1).

When red and near-infrared light is absorbed by cells, it stimulates ATP production, resulting in increased cellular activity and regeneration. Additionally, red light therapy is believed to reduce inflammation by decreasing the production of inflammatory mediators, such as pro-inflammatory cytokines, and increasing the production of anti-inflammatory factors (2).

Application in Pain and Inflammation Treatment

Red light therapy has been studied in various medical conditions involving pain and inflammation. Some of the most promising findings include:

Arthritis: A 2015 study by Bjordal et al. showed that red light therapy is effective in reducing pain and inflammation in patients with rheumatoid arthritis and osteoarthritis (3). Musculoskeletal pain: A 2018 study by Chow et al. found that red light therapy is effective in relieving musculoskeletal pain in various conditions such as carpal tunnel syndrome, lateral epicondylitis, and tendinitis (4). Sports injuries: Red light therapy has also shown to be helpful in the treatment of sports injuries such as sprains and muscle strains by accelerating healing and reducing inflammation (5). Wounds and ulcers: Red light therapy can also be beneficial in the treatment of skin wounds and ulcers by improving healing and reducing local inflammation (6).”



Red light therapy is a non-invasive and safe treatment option that can be helpful in managing pain and inflammation in various medical conditions. As research continues, it is expected that more applications for this innovative therapy will be discovered. However, it is important to note that red light therapy is not a one-size-fits-all solution for all conditions, and its effectiveness may vary depending on the individual and the severity of the condition.

It is essential for patients to consult with healthcare professionals before starting any treatment, including red light therapy, to ensure that it is appropriate and safe for their specific case.
