Quick Answer

Red light therapy, also known as photobiomodulation, is a low-level light treatment that has been around for over 50 years, first explored by Hungarian physician Endre Mester in the 1960s.
This therapy uses specific wavelengths of light to stimulate cellular processes, leading to increased ATP production in mitochondria, which helps cells repair faster and function better.
For safety and effectiveness, always choose an FDA-approved device, a recommendation emphasized by LHM Physical Therapy Institute.
Direct eye exposure should be avoided during treatment, and protective eyewear is recommended for all users.

Red light therapy, also called photobiomodulation or low-level light therapy, has become very popular in recent years. This non-invasive treatment uses specific light wavelengths, including visible red light and invisible near-infrared light, to penetrate the skin and stimulate cellular processes [https://atria.org/education/your-guide-to-red-light-therapy/]. The light particles are absorbed by mitochondria, the cell’s powerhouses, which then produce more ATP (cellular energy) [https://lhmphysicaltherapy.com/news/red-light-therapy-guide/]. This energy boost helps cells perform their functions more efficiently, leading to repair and regeneration. The therapy has been known for over 50 years, first discovered by Hungarian physician Endre Mester in the 1960s, who observed hair growth and wound healing in rats treated with red lasers [https://www.everydayhealth.com/wellness/red-light-therapy/guide/]. To get the best results and avoid common beginner mistakes, it is crucial to understand how red light therapy works, its proper uses, and important safety measures, such as using an FDA-approved device and protecting your eyes.

What is Red Light Therapy and How Does It Work?

Red light therapy, also known as photobiomodulation, is a low-level light treatment that applies infrared and near-infrared light directly to the skin. This method is different from tanning beds or UV rays because it is non-heating and non-damaging [https://lhmphysicaltherapy.com/news/red-light-therapy-guide/]. It has gained scientific credibility for its ability to stimulate cellular processes [https://atria.org/education/your-guide-to-red-light-therapy/].

The Science Behind the Light

The process starts when specific wavelengths of light, emitted by red light devices, penetrate deep into the skin. These wavelengths reach muscles, tissues, and even cells themselves. Inside the cells, these light particles, or photons, are absorbed by a protein within the mitochondria called cytochrome c oxidase [https://atria.org/education/your-guide-to-red-light-therapy/]. Mitochondria are often called the cell’s powerhouses. When they absorb these specific wavelengths, they produce more ATP (adenosine triphosphate), which is the primary energy currency of the cell.

This increase in ATP production means your cells get an energy boost. With more energy, cells can work harder, repair faster, and function better. This boost in cellular activity is linked to several important health benefits. For example, it improves blood flow, which is essential for delivering nutrients and oxygen to tissues. It also helps in the production of collagen and elastin, two proteins vital for skin structure and elasticity. Moreover, red light therapy reduces inflammation, a key factor in many chronic conditions and injuries. Finally, it accelerates tissue healing, making it useful for recovery from various physical stresses.

Different Names for the Same Therapy

Red light therapy goes by several other names in the scientific and medical communities. Jared Jagdeo, MD, founding director of the Center for Photomedicine at SUNY Downstate Health Sciences University, explains that red light therapy (RLT) is a type of photomedicine. This term refers to "the use of light to treat skin and other health conditions" [https://www.everydayhealth.com/wellness/red-light-therapy/guide/]. Praveen Arany, PhD, DDS, an associate professor at the University of Buffalo and interim director of the Center of Excellence for Photobiomodulation at Shepherd University, adds that another common term is photobiomodulation, or PBM for short. He also notes that low-level laser treatment (LLLT), photostimulation, and cold laser treatment are all terms used for the same therapy [https://www.everydayhealth.com/wellness/red-light-therapy/guide/]. Understanding these different names helps beginners recognize the therapy across various sources and contexts.

The Mechanism of Cellular Boost

When light hits the skin, it triggers a cascade of effects beyond just ATP production. The activation of cytochrome c oxidase also leads to the body’s antioxidant defenses being activated, which helps to reduce oxidative stress. Oxidative stress is a major contributor to cellular damage and aging. Additionally, red light therapy helps release nitric oxide. Nitric oxide is a molecule that improves blood vessel function and tissue repair. This improved circulation and reduced inflammation, particularly in the skin, enhances the body’s natural healing processes.

For beginners, understanding that red light therapy is not just about surface-level changes but deeply affects cellular function is crucial. It explains why the benefits are so wide-ranging, from skin health to muscle recovery and pain relief. The non-heating aspect means it does not cause thermal damage to tissues, making it a safe option for many. The goal is to energize cells so they can perform their natural functions more effectively, promoting overall wellness and healing.

What Are the Common Uses for Red Light Therapy?

People turn to red light therapy for many different health and wellness reasons.
