What is Red Light Therapy?
Red light therapy is a simple, non-invasive treatment that delivers concentrated natural light to your skin and cells. Red light therapy has an anti-inflammatory effect, and has been shown in numerous clinical studies to reduce pain and improve the healing process.
Red light therapy treatments are quick and simple: you just sit or stand in the light for 5 to 15 minutes, ideally every day. This stimulates your mitochondria and gives your cells the natural light they need to make energy.
Joovv’s light therapy products are registered with FDA as class II medical devices for the treatment of pain, strain, and inflammation.
How Does Red Light Therapy Ease Pain and Inflammation?
Red light therapy reduces inflammation by increasing blood flow and circulation to damaged tissues. Red light therapy also reduces oxidative stress and helps boost your ATP (adenosine triphosphate) cellular energy production. Producing more core cellular energy helps tissues regenerate and heal faster.  Numerous clinical studies have shown how red light therapy eases pain and reduces inflammation.
One of the main reasons red light therapy is so effective for healing joint, bone, and soft tissue may be the collagen boost many people experience with red light therapy.

Anti-Inflammatory Properties of Red Light Therapy
Dr. Michael Hamblin of Harvard Medical School is one of the world’s leading photomedicine researchers, and a member of Joovv’s Scientific Advisory Board. Dr. Hamblin has studied red light therapy at length and believes one of its most reproducible effects is “an overall reduction in inflammation, which is particularly important for disorders of joints, traumatic injuries, lung disorders and in the brain.” 
Dr. Hamblin says that wavelengths of natural red and near infrared light are “a very mild form of stress that activates protective mechanisms in the cells...for instance, when longer wavelengths or visibly red light hits the skin, it nudges mitochondria to make energy more efficiently and boost production of healing anti-inflammatories or disease-fighting antioxidants.” 
It’s no surprise people are looking for natural alternatives to treat inflammation and pain conditions. Over-the-counter drugs like ibuprofen and acetaminophen can have negative effects when overused. Chronic inflammation is typically treated with prescription drugs (NSAIDs) or nonsteroidal anti-inflammatory drugs, which come with a host of side effects, like kidney and heart damage. 
Red light therapy is a natural anti-inflammatory that’s been shown to reduce swelling, soreness, and strain in numerous clinical studies. And all without significant side effects or health risks. 
Less muscle pain and exercise soreness with red light therapy: Many studies have shown light therapy’s natural ability to ease muscle soreness and exercise-related inflammation. People who do a red light therapy treatment before a strenuous exercise record less pain and inflammation after workouts.  Red light therapy also helps prevent delayed onset muscle soreness (DOMS). 
World-class trainers use red light therapy for inflammation: Some of the world’s best trainers and fitness professionals use Joovv for clients struggling with inflammation. Jorge Cruise is one of Hollywood’s leading personal trainers. He says inflammation and joint pain is the #1 thing that keeps his clients from working out. Jorge recommends Joovv red light therapy to keep the swelling and soreness down before workouts and make training less painful.

Natural Pain Relief Benefits of Red Light Therapy
Red light therapy is a proven natural pain relief treatment, and Joovv is registered with the FDA for pain management. Studies have shown that red light therapy treatments can ease chronic pain like back pain, muscle pain, and knee and joint pain, and improve healing outcomes after injuries and surgeries, without pain medication or other OTC remedies.
Unlike painkillers and over-the-counter pain medications, natural light treatments don’t include major risks, side effects, or dependency issues. And unlike natural pain relievers and popular herbal remedies like turmeric, curcumin, capsaicin, and boswellia, red light therapy treatments are backed by a large base of peer-reviewed clinical research.
Less pain and inflammation after surgery: Red light therapy treatments have been shown to reduce swelling and inflammation after surgeries, and enhance the post-op healing process. [7,8] Patients have also been shown to heal faster from plastic surgery, with less pain and inflammation.

Red Light Therapy for Arthritis and Joint Pain
Red light therapy is used as a natural joint pain and arthritis treatment.
Rheumatoid arthritis results: The best results in a major review of arthritis cases was found in people suffering from rheumatoid arthritis pain. Patients’ pain was reduced by up to 70 percent with red light therapy treatments. 
Less morning stiffness: Red light therapy also reduced morning stiffness in participants by 27.5 minutes, and significantly increased hand flexibility. 
Improved hand osteoarthritis: Red light treatments were also shown to significantly reduced pain in women with osteoarthritis. 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. 
Relief from fibromyalgia joint pain: Dr. Sarah Ballantyne (aka Paleo Mom) is a biophysicist and New York Times best-selling author. Dr. Sarah says using Joovv has kept her joint pain at bay better than anything else she’s tried.

Red Light Therapy for Back Pain
Red light therapy has shown promising results spinal injuries and low back pain. A 2016 study concluded that the combination of red light therapy and stretching decreased spinal pain more effectively than just placebo therapy. 
Gold medalist Dutch gymnast Sanne Wevers uses Joovv red light therapy for injuries and strain when she trains, especially for back injuries and back pain.
My back has always been one of my biggest concerns and it’s taken me years to get the pain under control so I can train at an elite level. Nothing has been as effective as using my Joovv. When I shine red light on my back for 10-15 minutes a day, I can clearly tell that my post-training recovery is faster and the pain is less noticeable
Red Light Therapy for Knee Pain
In study after study, red light therapy has reduced people’s knee pain and increased their knee function.  A large base of research shows red light therapy reduces pain from knee osteoarthritis and improves patients’ quality of life. [13,14,15,16,17] Red light therapy treatments have also helped patients with meniscus tears avoid invasive knee surgery. 
Cartilage regeneration: Instead of simply numbing pain, red light therapy treatments address the root cause of injuries by increasing blood circulation and stimulating natural knee cartilage regeneration.

Healing Burns with Red Light Therapy
Red light therapy has shown great results for healing burns and reducing the pain and inflammation from burns. Red light therapy improves burns by reducing inflammation and increasing new tissue formation.  A 2018 study also showed red light spurred development of new blood vessels, and stimulated fibroblasts (cells that aid in tissue repair). 
Almost every lab study on red light therapy and burn healing has noted a significant decrease in inflammation levels versus placebo and control groups. [20,21,22,23,24] Less inflammation means less pain and discomfort during the burn recovery process.

Other Health Benefits of Red Light Therapy
Emerging clinical research is also showing the potential for other red light therapy benefits, like skin rejuvenation, and better sleep and circadian rhythm. The initial research is also encouraging for brain and cognitive health, and mental health treatment, as well as for red light therapy and hormone health.
See all the health benefits of red light therapy on this page.
Side Effects and Risks of Red Light Therapy Treatments
Red light therapy has been tested and analyzed in thousands of peer-reviewed trials. The consensus among medical researchers and the clinical community is that natural light treatments are safe, well-tolerated, and produce little to no side effects. Research teams have concluded this in study after study.
Researchers from Harvard Medical School conducted a review of red light therapy in 2013 and praised its “noninvasive nature and almost complete absence of side effects.” 
Red light therapy does not use heat to induce a biological reaction like some therapies, and is not a heat risk to skin. People with specific photosensitivity concerns should check with their healthcare provider.
