How Does Red Light Therapy Relieve Arthritis?

What is arthritis?

Arthritis refers to the condition of joint pain or joint disease. This can happen to anyone of any age. In North America, more than 60 million people are experiencing some form of arthritis.

What is red light therapy?

The human body needs natural light to function and thrive, just as it needs moisture and nutrients from food.

Red and near-infrared wavelengths of light are the “superfoods” of natural light, providing our bodies with therapeutic properties and health benefits.

Red light therapy is a non-invasive treatment that delivers concentrated red and near-infrared light to your cells. You only need 10-15 minutes a day to optimize your body.

How does red light therapy reduce joint and arthritis pain?

Red light at 660nm and near-infrared light at 850nm provide therapeutic benefits for symptoms of joint and arthritis pain by increasing mitochondria, blood circulation and collagen production

Mitochondria are the powerhouse of our cells to produce adenosine triphosphate (ATP), the energy molecule that powers everything the body does. Enhances cellular function by increasing ATP production when stimulated by red light therapy. With more energy, the body can function optimally.


Collagen is an important protein produced by the body that helps build healthy bones, skin, hair, tendons and connective tissue. As the body ages, collagen production slowly decreases. Red light therapy has become one of the most popular alternative treatments to boost collagen production. With more collagen, the body can produce more connective tissue and cartilage to protect bones from rubbing against each other. This creates a cushion between the bones to enhance joint space and further allow a greater range of motion for the joint.

blood circulation

Blood circulation is one of the most important functions of the human body. This is how essential nutrients and oxygen are delivered to the brain and body. Red light therapy improves blood flow by stimulating the production of nitric oxide (NO) in our cells. One of the main functions of nitric oxide is to relax the walls of blood vessels, increasing blood flow through arteries and veins. With increased blood circulation, the body is able to deliver more nutrients and oxygen to the affected area and remove unwanted waste products that can cause inflammation.

oxidative stress

Oxidative stress is an imbalance between free radicals and antioxidants in our body. Free radicals are harmful molecules that are produced naturally through metabolic activities such as digestion and exercise. Antioxidants play a central role in counteracting free radicals and reducing oxidative stress. Uncontrolled levels of oxidative stress can cause cellular damage and accelerate the body’s aging process. Red light therapy reduces oxidative stress by upregulating the production of antioxidant enzymes, preventing further damage to cells and premature death.


Osteoarthritis is one of the most common forms of arthritis, where cartilage, the cushion between two bones, wears out and deteriorates. This causes the two bones to rub against each other, causing pain, inflammation, and stiffness. As this problem progresses, joints can lose strength and integrity, leading to chronic pain.

Red and near-infrared light have been shown to significantly reduce oxidative stress and inflammation in knee osteoarthritis. This is due to the increased production of antioxidants in the knee joint when red light therapy targets the area.
