Quick Answer

Red light therapy, or photobiomodulation, uses low-level red and near-infrared light applied directly to the skin, differing from tanning beds or UV rays because it is non-heating and non-damaging (https://lhmphysicaltherapy.com/news/red-light-therapy-guide/).
This therapy works by emitting specific wavelengths of light that are absorbed by mitochondria, the cell's powerhouses, leading to increased production of ATP (cellular energy) (https://lhmphysicaltherapy.com/news/red-light-therapy-guide/).
Benefits include improved blood flow, enhanced collagen and elastin production, and reduced inflammation, which supports accelerated tissue healing (https://lhmphysicaltherapy.com/news/red-light-therapy-guide/).
For most people, red light therapy is generally considered low risk, and side effects are rare, though protective eyewear is recommended to avoid direct eye exposure (https://lhmphysicaltherapy.com/news/red-light-therapy-guide/).

Red light therapy, also known as photobiomodulation (PBM) or low-level light therapy (LLLT), is a non-invasive treatment that harnesses specific wavelengths of light to stimulate cellular processes. This technique involves applying infrared and near-infrared light directly to the skin, which then penetrates deep into tissues and cells. Research suggests these specific wavelengths are absorbed by mitochondria, the powerhouses of cells, leading to increased production of ATP, or cellular energy (https://lhmphysicaltherapy.com/news/red-light-therapy-guide/). This boost in cellular activity is linked to improved blood flow, increased collagen and elastin production, and reduced inflammation, ultimately supporting faster tissue repair and regeneration (https://lhmphysicaltherapy.com/news/red-light-therapy-guide/). While red light therapy is generally considered low risk for most individuals, with side effects being rare, it is crucial to understand its mechanisms and general safety guidelines. It is important to note that the existing research on red light therapy does not specifically address its use or safety during pregnancy. Therefore, any pregnant individual considering this therapy must consult with a qualified healthcare provider before beginning treatment.

What is Red Light Therapy and How Does it Work?

Red light therapy, often called photobiomodulation (PBM) or low-level light therapy (LLLT), is a method that uses specific wavelengths of light to interact with the body's cells. This non-invasive treatment applies visible red light and invisible near-infrared light directly to the skin. The goal is to stimulate cellular processes without heating or damaging the skin, making it different from other light-based treatments like tanning beds or UV rays (https://lhmphysicaltherapy.com/news/red-light-therapy-guide/).

The Science Behind Photobiomodulation

When these specific light particles, or photons, penetrate the skin, they are absorbed by a key protein inside the mitochondria of cells. This protein is called cytochrome c oxidase (https://atria.org/education/your-guide-to-red-light-therapy/). Mitochondria are often referred to as the "powerhouses" of the cell because they produce adenosine triphosphate (ATP), which is the primary energy currency of the cell. The absorption of light by cytochrome c oxidase leads to an increase in ATP production (https://atria.org/education/your-guide-to-red-light-therapy/).

This boost in cellular energy allows cells to perform their functions more efficiently, including repair and regeneration. Beyond ATP production, this process also activates the body’s antioxidant defenses, helping to reduce oxidative stress (https://atria.org/education/your-guide-to-red-light-therapy/). It also triggers the release of nitric oxide, which is known to improve blood vessel function and support tissue repair (https://atria.org/education/your-guide-to-red-light-therapy/). The combined effect of increased energy, antioxidant activity, and improved circulation helps cells to function better and recover faster.

A Brief History of Light Therapy

Light therapy has a history spanning more than 50 years. Its origins trace back to the 1960s, when Hungarian physician Endre Mester conducted scientific experiments involving red lasers on rats.
