What are the benefits of infrared red light therapy?

By Brian James Rose

Infrared light therapy – also known as: “photo-bio-modulation (PBM)”, “red light therapy” or simply “infrared therapy” – is primarily a modern approach to pain relief. It has demonstrated success with both chronic and acute pain management. In practice, the idea behind the therapy is to isolate the infrared wavelength of light from the electromagnetic spectrum (EM) and deliver it to sites of pain and discomfort in the body. This has been found to have regenerative and healing effects on cells as we are going to explore later in this article. While infrared light therapy is a new age technique, the concept of electromagnetic therapy dates back thousands of years. Some of our ancestors are believed to have used electric eels to provide electric shocks for various forms of treatment. 

How Does It Work?

Infrared wavelengths range between 700 nanometers and 1,000 nanometers. A 2015 study conducted by Theodore Henderson, MD, Ph.D. and Larry Morries, DC, investigated the depth of infrared penetration in the body. Depending on the strength of the infrared light, it can penetrate inner layers of the skin to a depth between two millimeters and more than three centimeters. At such depths, infrared light gets absorbed by photoreceptors located within the cells leading to a series of metabolic events – among which include cell regeneration. Let’s now go over the benefits of infrared light therapy in more detail.

BENEFITS OF INFRARED LIGHT THERAPY

Reduces Inflammation

In one study involving nearly 40 arthritis patients as participants, red light therapy was found to produce significant results in terms of pain relief and improved function in the patients. There have also been other studies that support infrared therapy for arthritic joint inflammation.

Builds Collagen and Improves Skin Complexion

Infrared therapy has also been investigated for its potential impact on boosting skin collagen and skin complexion. A 2014 study by researchers at Medical Light Consulting and JK-International GmbH in Germany concluded that “application of infrared full-body treatment or large-area modalities provides a safe, non-ablative, non-thermal, atraumatic photo-bio-modulation treatment of skin tissue with high patient satisfaction rates”. The researchers also noted that therapy is ideal for anti-aging treatment options. 

Facilitates Healing of Wounds

Some studies have recorded success in wound healing with infrared therapy – particularly in burns, skin grafts, infections, and amputations. Infrared light reduces the production of inflammatory factors while simultaneously boosting the regenerative activities of connective tissues. 

Promotes Healing of Traumatic Brain Injury

Because of limited options in terms of treatment for traumatic brain injury, many researchers have been looking into infrared light therapy. In one study by the founders of Neuro-Laser Foundation, published in the Neural Regeneration Research Journal, it was noted that Near Infrared (NIR) therapy is a “safe and effective modality for traumatic brain injury treatment”. Infrared induces a persistent, and possibly progressive, change in neurological function. 

Improves Mood

Although more scientific research is definitely required, infrared light therapy has been shown to have an impact on mood. In one study involving 70 participants with insomnia and depression, red light therapy was noted to have an impact in increased levels of serotonin in the blood. This is a chemical known to improve low and “off” moods. In another study involving rats as participants, long-term red light therapy was found to alleviate anxiety and depression characteristics in rodents.

Does Red Light Therapy Improve Blood Circulation?

While some studies record an increase in blood circulation using infrared therapy, some have shown inconclusive results. Near-infrared light, therapy does not seem to have a significant impact on blood circulation. However, far-infrared light therapy is something that a lot of researchers are currently looking into. One of the biggest hurdles for scientists will be to isolate the impacts of the infrared from that of increased temperature as a result of the therapy. 

To conclude, there have been no adverse side effects of infrared light – particularly mild red light therapy – to date. It is, therefore, generally considered safe for most people; including infants. 

What About Cancer Treatment?

In scientific studies involving mice, some forms of infrared radiation therapy are suspected to have anti-tumor properties. It is also believed that the radiation may cause nearby cells to become toxic; therefore, this approach is still highly experimental. More research is still needed before light therapy can be accepted as a mainstream form of cancer treatment.
