Red Light Therapy for Pain: How It Can Help

Pain is a universal experience, one that many of us wish we could shine a light on and make vanish like magic.

People are often eager to explore beyond traditional medicine and find less-invasive, drug-free solutions when it comes to managing pain. One such solution that has been gaining popularity is red light therapy for pain. Although it’s applicable to all pain, it’s increasingly being used to manage back pain.

Red light therapy (a form of photobiomodulation) involves exposing body tissues to red and near-infrared light to help reduce pain and inflammation.

But what exactly is red light therapy, and how can it provide relief for various types of pain?

Let’s dive into the science and applications of this pain-reduction method.

What Is Red Light Therapy?

Red light therapy (RLT) uses low-level red and near-infrared light to penetrate the skin and interact with the body’s tissues. By directly stimulating mitochondria, the “powerhouse” of our cells, this therapy can prompt an uptick in ATP production, which is like giving cells a burst of energy.

With this increased vitality, cellular functions can go into overdrive, potentially accelerating repair and diminishing the sensation of pain.

There are various types of devices that red light therapy can be performed with:

  • Pads: For those seeking a therapy tool that’s both small and highly portable for on-the-go treatments, red light mats are an excellent choice. They lend themselves to localized treatments, making them ideal for muscles or joints that require singular focus.
  • Panels: When the objective is broader coverage, panels are designed to ensure that more of the body receives therapeutic light. They are common in clinical settings and serve well in home therapy setups.
  • Beds: Beds offer the most comprehensive exposure to red light therapy, providing users with the ability to receive treatment from head to toe. These are popular in both clinical and home settings.

How Can RLT Help with Pain and Inflammation?

By targeting the body’s blood vessels, RLT encourages increased blood circulation, which in turn enhances the delivery of oxygen and nutrients to the affected area. The outcome is an acceleration of natural tissue repair processes that can potentially alleviate pain linked to decreased blood supply, or ischemia.

Mitochondria, the cellular organelles responsible for energy production, readily absorb red and near-infrared light. This absorption kick-starts the synthesis of ATP, the primary energy source for cellular operation. With more energy available, cells can perform their functions more effectively, contributing to accelerated healing and reduced pain from injuries or ailments.

RLT has also shown promise in promoting cell growth and specialization, both fundamental processes for wound healing and the regeneration of healthy tissue. By indirectly managing the root causes, RLT can have a significant impact on chronic pain from issues such as inflammation, arthritis, or tendonitis.

Red light therapy can help harmonize the body’s inflammatory response, reducing the production of harmful inflammatory substances while promoting the generation of anti-inflammatory factors. This balanced approach can not only help in recovery but also enhances the management of pain caused by inflammatory conditions.

Red Light Therapy for Back Pain: How It Can Work

There are specific benefits of red light therapy for back pain, including the following:

Osteoarthritis-related pain (joint pain)

For individuals with osteoarthritis, RLT’s potential to influence cartilage repair and reduce inflammation offers a complementary method to alleviate joint discomfort in the spine.

Muscle tension and spasms

Individuals can find relief through the improved blood flow and anti-inflammatory effects that red light therapy for pain is believed to induce, resulting in relaxed muscles and reduced spasms.

Herniated discs

The therapy’s proposed ability to lessen inflammation and encourage nerve regeneration may help manage the resulting pain.


The anti-inflammatory properties of RLT offer hope for alleviating nerve pain and delivering tangible relief.

Clinical Studies

Many clinical trials have shown that therapy can help those suffering from back pain.

Photobiomodulation is a promising pain management approach for musculoskeletal issues. It offers a drug-free solution, reducing inflammation and promoting healing with low-intensity LASER and LED therapy.

PBMT’s non-invasive characteristics, coupled with its evidence-based effectiveness, make it an especially compelling solution in light of the opioid crisis. It targets conditions like osteoarthritis, fibromyalgia, and temporomandibular disorders, providing a great alternative for pain management.

In one trial, researchers studied the effects of infrared (IR) therapy on chronic low back pain. Forty patients were divided into two groups: one received IR treatment through portable units in a waistband, while the other received a placebo.

The results are promising, with participants in the IR therapy group reporting a significant decrease in pain levels from 6.9 to 3 on a scale of 10 over seven weeks. The placebo group had a milder reduction, from 7.4 to 6. Importantly, the study found that IR therapy was safe and effective for chronic low back pain.

Different Types of Pain RLT May Help With

Red light therapy for pain management is gaining recognition for its potential to alleviate a variety of pain types, including the following:

Arthritis in other joints

RLT can limit inflammation and encourage the regeneration of cartilage. This is significant for pain management in conditions like osteoarthritis in various joints like the knees, hips, and smaller joints in the hands and feet.


RLT can enhance circulation and decrease tissue inflammation. These effects can help alleviate symptoms of tendinitis, including tendon inflammation and associated pain.

Carpal tunnel syndrome (wrist pain)

By diminishing wrist nerve inflammation and swelling, RLT can provide relief from the numbness and discomfort that’s associated with carpal tunnel syndrome.

Sports injuries

RLT’s potential to promote faster tissue repair, control inflammation, and lessen post-exercise soreness offers promising outcomes for recovery and re-entry into physical performance.

Knee pain

RLT’s effect on inflammation modulation, tissue repair, and enhanced blood flow could prove beneficial for knee-related issues, potentially providing a robust treatment approach that complements traditional therapies.

How to Use Red Light Therapy for Pain Management
