Arthritis and related joint problems affect over 50 million American adults. The resulting pain has long been the nation’s #1 cause for disability, and is typically managed with medication and surgery. 
This article examines the large base of clinical research on arthritis with a natural treatment— red light therapy (aka photobiomodulation or PMB). In studies around the world, researchers have concluded that red and near infrared light has a significant effect on reducing joint pain and increasing function & activity for people with arthritis. More positive studies come out every year, and we’ll summarize several below.
Arthritis in America
Across those 50 million Americans with arthritis, there are over 100 ways it presents and various ways it starts. But the bottom line for most people with any kind of arthritis is pain and inflammation—swollen and stiff joints that limit movement & activity level and chip away at your quality of life over time. 
Some forms of arthritis can go into remission if the person keeps up with medical treatments and lifestyle recommendations. However, traditional medicine offers no cure for arthritis. The best hope is usually to manage the disease via treatments with pharmaceuticals and/or surgery. In some cases, doctors may also recommend natural treatments like vitamins, minerals & herbs, massage, electrical stimulation, and hot & cold therapy.
There’s a wealth of peer-reviewed clinical research showing red and near infrared wavelengths of light have a significant & positive effect on arthritis symptoms like joint pain and inflammation by targeting the cellular origins of this debilitating disease.
What is Red Light Therapy
The short version is this: light therapy is natural, non-invasive, and drug-free. A device like a Joovv delivers safe, concentrated wavelengths of therapeutic natural light to your skin and cells, where it reduces oxidative stress and stimulates cellular energy production (adenosine triphosphate or ATP). That helps your body power itself, regenerate & heal faster, and reduce joint pain and inflammation.
Red light therapy’s positive effects on arthritis, joint pain, and inflammation have been well-documented across hundreds of trials over the last three decades. This is a brief overview of significant findings for osteoarthritis and rheumatoid arthritis, as well as hand, wrist, knee, and spinal pain.
Red Light Therapy for Knee and OsteoarthritisMany studies have been conducted specifically on red light therapy and knee osteoarthritis. More are coming out all the time. In 2018, two separate Brazilian studies concluded that red light therapy plus exercise or stretching was significantly more effective at treating osteo-related knee pain than just stretching or exercise alone [2,3] Researchers of one study concluded patient’s knees “showed reduced pain and increased physical functionality after 3 months of stretching plus [red light] therapy.” 
Osteoarthritis Knee Pain: Since 2015, a chorus of other studies in major journals have found that natural red light therapy significantly reduces knee pain from osteoarthritis. [4,5,6]
Increased Range of Motion: Recent research on knee pain builds on previous research showing red light therapy not only decreases knee pain, but also increases functionality and range of motion. [7,8]
Cartilage Regeneration: A 2017 study in Lasers in Medical Science assessed knee cartilage in animal studies and found red light very significantly reduced pain and improved knee cartilage regeneration through “biochemical changes.” In other words, it addressed root causes, not just numbed symptoms. 
Treating Meniscus Tears: European researchers conducted a double-blind, placebo-controlled trial in 2013 on pain levels in patients with meniscal pathology (meniscus tears). They concluded: “Treatment with light therapy was associated with a significant decrease of symptoms compared to the placebo group: it should be considered in patients with meniscal tears who do not wish to undergo surgery.” 
General Knee Pain: Red light therapy can improve general joint problems that are unrelated to arthritis as well. A systematic review in The Australian Journal of Physiotherapy looked at 11 clinical trials of light therapy for chronic joint disorders in the knee. Across all of these studies, light therapy reduced pain while improving overall joint function. 
Red Light Therapy for Hand and Wrist Pain
Hand Osteoarthritis in Women: A 2015 systematic review in Lasers in Medical Science found that red light therapy plus ultrasound showed strong results for treating hand osteoarthritis in women, with a major decline in pain. This meta-analysis also documented extensive, positive results for the use of light therapy for arthritis in the knees, neck, back, jaw, and other areas. 
Bouchard’s & Heberden’s Nodes in the Hand: A 2016 German study published in Lasers in Surgical Medicine analyzed red light therapy’s effect on the hands of 34 people with the bony outgrowth and swelling conditions known as Bouchard’s nodes & Heberden’s nodes. Researchers found light therapy “significantly reduced pain & ring size and increased range of motion” and that “the effects were very large.” 
Red Light Therapy for Spine Pain
Recent research is also showing potential to treat spinal joint pain from conditions like Ankylosing spondylitis. A 2016 European study concluded that the combination of red light therapy and stretching exercises decreased spinal pain more effectively than just placebo therapy with stretching in patients with Αnkylosing spondylitis. 
Emerging Research Shows Light Therapy Can Treat Root Causes of Arthritis
Conventional medicine manages arthritis symptoms, but doesn’t offer a cure. Emerging laboratory research in 2018 is showing that red light therapy has the potential to treat arthritis at a cellular level and address the root causes.
Photomedicine researchers in Brazil published a study in late 2018 showing that red light therapy decreased all cytokine levels after therapy and increased immune cell populations in mammals. Researchers concluded: “Our results indicate that light therapy could change the inflammatory course of arthritis, tending to accelerate its resolution through immune cells photobiostimulation.” 
Decades of Positive Research on Red Light Therapy and Arthritis
There have been numerous positive red light therapy and arthritis studies in recent years, building on a base of positive findings from prior decades to make up a huge base of evidence in favor of the therapy as a safe and effective treatment for arthritis pain.
A systematic review in The Journal of Rheumatology found significant results across thirteen randomized controlled arthritis trials that had been conducted prior to the year 2000:
Rheumatoid Arthritis: The best results were demonstrated in people suffering from rheumatoid arthritis, with light therapy reducing participants’ pain by 70 percent compared to the placebo.
Morning Stiffness: Red light therapy reduced morning stiffness in participants by 27.5 minutes, and significantly increased hand flexibility. 
Health and Fitness Leaders Trust Joovv for Joint Pain and Inflammation
In addition to the huge base of clinical research, there are the health & fitness leaders using Joovv for joint pain and inflammation today and seeing incredible results.
Dr. Sarah Ballantyne, aka Paleo Mom, has spoken about how 3 months of using a full-body Joovv every day made her joint pain mostly disappear, for the first time in many years. She called it a major a life-changer. Results have been similar for people treating hormone-related challenges with red light therapy.
Jorge Cruise is a top celebrity trainer. He says inflammation and joint pain often keep his clients from working out, so he recommends Joovv red light therapy to keep inflammation down and make training less painful on an everyday basis. Check out other influential trainers and fitness pros who use Joovv here.
The experiences of health professionals match the positive results of regular Joovv users we hear about every day.
