Red light therapy (RLT), also known as photobiomodulation (PBM) or low-level laser (light) therapy (LLLT), is a non-invasive treatment that exposes the skin to specific wavelengths of red and near-infrared (NIR) light. This process stimulates cellular activity and offers a variety of potential health benefits. RLT is widely used for skin rejuvenation, muscle recovery, pain relief, and more. Red and near-infrared light are part of the electromagnetic spectrum, specifically within the portion of the spectrum emitted by the sun. These wavelengths are considered "bioactive" for humans.
The electromagnetic spectrum encompasses various wavelengths of electromagnetic energy. The wavelength of this energy determines its properties.
How Does Red Light Therapy Work?
Red light therapy works primarily through the following mechanisms:
· Collagen Production: Red light can stimulate skin cells to produce more collagen, which can improve skin elasticity, reduce wrinkles, and enhance skin texture. [This relates to the broader field of photobiomodulation and collagen synthesis. Here's a relevant review: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3926176/]
· Wound Healing: Red light can promote blood circulation, accelerating wound healing and reducing inflammation. [This study explores the effects of LLLT on wound healing: https://pubmed.ncbi.nlm.nih.gov/11777011/]
· Pain Reduction: Red light may help reduce pain by inhibiting the activity of nerve endings and reducing inflammation. [This review discusses the mechanisms of pain relief with photobiomodulation: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5523874/]
· Antioxidant Effects: Red light can enhance the activity of antioxidant enzymes within cells, reducing damage from free radicals. [This study explores the antioxidant effects of photobiomodulation: https://pubmed.ncbi.nlm.nih.gov/24286289/]
The powerful effects of red light therapy extend beyond physical recovery and pain relief to include potential improvements in quality of life, anti-aging effects, and even potentially influencing longevity.
Red light therapy has been the subject of numerous scientific studies, with thousands of research papers supporting its efficacy. Research indicates that RLT can significantly improve cellular metabolism, reduce inflammation, and enhance tissue repair.
The photochemical reactions triggered by red light therapy are similar to photosynthesis in plants, where light energy is converted into chemical energy to promote cellular health and function.
RLT works by delivering red (620-660nm) and near-infrared (810-850nm) light through the skin, where it is absorbed by mitochondria within cells. Mitochondria, known as the cell's powerhouses, produce adenosine triphosphate (ATP), the cell's energy currency.
Upon absorption, red light enhances mitochondrial function, leading to increased ATP production. This boost in cellular energy enhances cellular repair, regeneration, and overall function.
While light plays many vital roles in health, modern individuals are increasingly exposed to less natural sunlight. Our housing, transportation, and workplaces are often indoors, reducing our access to the beneficial effects of natural sunlight. Furthermore, modern LED and CFL lighting lacks the beneficial red and near-infrared wavelengths, and energy-efficient windows in buildings and vehicles further restrict our exposure to these wavelengths.
Is Red Light Therapy Safe?
Red light therapy is widely considered one of the safest light therapies available. This is because red and near-infrared light are low-energy forms of electromagnetic radiation. Short-wavelength light, such as ultraviolet (UV) light, is considered high-energy light with known health risks, such as skin cancer and retinal damage.
Red light has no known safety risks. While red light therapy providers often recommend wearing protective eyewear during treatments out of an abundance of caution, there is no solid evidence suggesting that red light therapy causes eye damage. In fact, some evidence suggests that red light therapy may have benefits for the eyes.
While RLT is considered very safe, there are some situations where it is not recommended. However, these situations are not due to known dangers but rather because safety has not been fully researched or proven. For example, using red light therapy on the abdomen during pregnancy does not pose any known risks; however, it has not been definitively proven safe, and most researchers would not test it in case there are some unknown negative effects.

Practical Tips for Effective Red Light Therapy Treatments:
To maximize the benefits of red light therapy, follow these practical tips:
· Consistency is Key: Regular use is crucial for achieving optimal results. Incorporate red light therapy into your daily routine and stick with it.
· Clean Skin: Ensure your skin is clean and free of lotions or oils before treatment, as these can block light penetration.
· Stay Hydrated: Drinking plenty of water before and after sessions helps keep your skin hydrated and supports cellular function.
· Be Patient: While some benefits may be noticeable quickly, others may take several weeks to appear. Be patient and consistent with your treatment plan.
