Joint pain is one of the most common health conditions, with over a third of adults reporting joint discomfort in national surveys. Arthritis, a leading cause of disability, affects nearly 60 million adults and 300,000 children in the United States alone. Whether caused by arthritis, injury, or overuse, joint pain can significantly impact quality of life, limiting mobility and daily activities. Red light therapy (RLT), also known as photobiomodulation or low-level laser therapy, has emerged as a promising non-invasive treatment for managing joint pain and inflammation.

What is Red Light Therapy?


Red light therapy is a simple, non-invasive treatment that uses LEDs to deliver red and near infrared (NIR) wavelengths of light to the body and cells. It’s a popular modality with trainers and sports medicine professionals, and there’s a growing body of peer-reviewed clinical research showing that red light therapy treatments can improve pain symptoms in joints. Red light therapy devices deliver concentrated wavelengths of therapeutic light to your skin and cells, which can help reduce oxidative stress and stimulate cellular energy production (adenosine triphosphate or ATP). This helps your body power itself, leading to many benefits including improved blood circulation and reduced joint pain and inflammation.

Red light therapy uses wavelengths in the range of 630nm to 850nm, which falls between the visible red light spectrum and the near-infrared light spectrum. Visible red light refers to wavelengths between 630nm and 660nm, which fall within the red spectrum of visible light. This range is easily absorbed by the surface layers of the skin, making it highly effective for surface-level treatments. This wavelength penetrates just a few millimetres into the skin, making it ideal for addressing superficial conditions like mild inflammation and shallow joint discomfort.

Infrared therapy typically uses longer wavelengths that can penetrate deeper into muscles and joints. This makes it ideal for addressing deeper tissue issues such as chronic pain or inflammation. LED therapy primarily utilizes visible red light wavelengths. While it may not penetrate as deeply as infrared therapy, it is effective for treating surface conditions and can still benefit joint health by stimulating cellular metabolism at the skin level. Depending on your specific needs and the type of knee pain experienced, one method may prove more beneficial than the other. For many, a combination of both therapies can offer comprehensive relief.

How Does Red Light Therapy Help Joint Pain?


Red light therapy works by stimulating the mitochondria, which are the energy-producing powerhouses of cells, to increase ATP production. ATP is an essential molecule that provides energy for cellular processes, including tissue repair, regeneration, and growth. Additionally, red light therapy can reduce the production of pro-inflammatory cytokines that contribute to inflammation and pain. Red light therapy has also been shown to stimulate the production of collagen and elastin, two proteins that are important for joint health. Collagen provides structural support for joints, while elastin helps to maintain joint flexibility. By promoting the production of these proteins, red light therapy can help to strengthen and protect joints from damage.

One of the primary benefits of red light therapy is to treat chronic (ongoing) inflammation, which eases pain in joints and muscles. Chronic pain management often involves a complex blend of therapies. Red light therapy can be an incredible adjunct therapy that complements traditional treatments. What’s more, with whole-body red light therapy, you might even treat other sources of pain you weren’t focusing on. Pain relief without medicine or surgery might sound too good to be true, but red light therapy offers exactly that. Red light therapy uses photobiomodulation, which is a low-level laser therapy that delivers red and near-infrared light to areas of your body. In doing this, it helps regenerate (or grow back) cells, restore cell function and trigger blood flow.

Red light therapy has anti-inflammatory effects due to the modulation of cellular processes and immune responses. Once the light is absorbed by the cells, inflammation can be reduced. This form of therapy can directly focus on the joint and inflammation and speed up the healing process, faster than the body’s natural response. In turn, moving as you normally would do will feel easier as pain and swelling can be lowered. Arthritis can inflict chronic pain which can feel debilitating and prevent you from doing what you love - whether that’s painting, exercising, or any other hobby. With treatment to lower the pain and other symptoms, many people go on to live full active lives.

Scientific Evidence Supporting Red Light Therapy


Clinical studies show that red light therapy is an effective tool in relieving arthritic pain. Patients have reported significant improvement in both acute small joint inflammation and chronic pain (80% success rate in relieving pain). In a review article on rheumatology, some 18 papers were considered. All studies involved double-blind trials with photobiomodulation in chronic rheumatoid arthritis patients and reported significant improvement in both acute small joint inflammation and chronic pain. A different study of 170 patients with rheumatoid arthritis using photobiomodulation showed pain attenuation (pain reduction) of up to 90%. Red light therapy also accounted for increased cellular rejuvenation and blood flow, which play an important role in improving joint and tissue health in arthritic hands.

In one double-blind clinical study, 50 patients with degenerative osteoarthritis in both knees were treated with either red light, infrared light, or a placebo for ten days. There were no significant pain improvements in the placebo group. But the red and infrared groups saw their pain reduced by over 50%. This led the research team to conclude that red light therapy “is effective in relieving pain and disability in degenerative osteoarthritis of the knee.”

A 2018 experimental study demonstrates that red light therapy targets cellular function within the joints. Hence, it focuses on the root cause of arthritis. In the last quarter of 2018, Brazilian researchers in the field of photomedicine published a study which indicated that cytokine levels were reduced and immune function boosted on the application of red light therapy. They concluded that light therapy alters the pathway for inflammation caused by arthritis, and increases the rate at which inflammation is reduced via immune cells photobiostimulation.

Benefits of Red Light Therapy for Joint Pain


Red light therapy offers several key benefits for individuals with arthritis. Inflammation is a key symptom for arthritis and is known to drive swelling, pain, and limited mobility of the impacted area. Red light therapy can be an effective treatment for arthritis by using specific wavelengths of light to penetrate deep within the cells to help reduce inflammation. Arthritis is also characterized by chronic pain, which can feel debilitating and prevent you from doing activities you love. Red light therapy is an effective tool for modulating pain signal transmission and can stimulate your cells’ natural healing processes. Additionally, joint stiffness is a common challenge of arthritis, leading to the sensation of “locked joints” and overall reduced range of motion. Red light therapy treatment can help lower swelling in the area and improve blood flow to relieve joint stiffness and enhance overall mobility.

  • Reduced Inflammation: Red and near-infrared light has been scientifically proven to decrease the production of pro-inflammatory cytokines and other inflammatory markers, helping to alleviate swelling and discomfort.

  • Pain Relief: By quieting nerve signals and reducing inflammation, light therapy can effectively diminish the perception of arthritis pain and help activate the body’s pain-relieving pathways.

  • Improved Blood Flow: Enhanced circulation delivers vital oxygen and nutrients to affected areas, facilitating the removal of metabolic waste products. This process is crucial for healing and recovery, as it combats the stiffness and pain often associated with joint issues.

  • Collagen Production: The ability of RLT to accelerate the production of collagen and elastin is particularly beneficial for joint health. Collagen encourages the development of cartilage, the connective tissue that absorbs impact and prevents friction in your body’s joints.
