Using Red LED Lights to Alleviate Chronic Pain

Types of chronic pain that can be relieved by the therapy

Chronic pain is a debilitating condition affecting millions of people worldwide. It can significantly impair a person’s quality of life, making it difficult to perform daily tasks and enjoy activities. Unfortunately, conventional treatments can have serious side effects and a risk of addiction. As a result, there is a growing interest in alternative pain management methods.

Heating pads are an old but effective way to relieve pain. The scientific basis and features of this method were investigated by Dr. Jose Diego Mier to understand which heating pad is right for you. 

Another, more modern method is the use of red LED lamps. And in this article, we will look at their advantages as an alternative method of pain relief. We will explain how it works, what types of chronic pain they can reduce, and how to use them to achieve the desired result.

How red LED lights work

The therapy works by using special wavelengths of red LED light that penetrate the skin and stimulate the body’s natural healing mechanisms. When the light is absorbed by the skin, it activates the mitochondria in the cells, which are responsible for energy production. This process, known as cellular respiration, results in the release of adenosine triphosphate (ATP), which the body uses to perform a wide range of cellular functions.

Red LED light can also increase blood flow and reduce inflammation. The enhanced process delivers oxygen and nutrients to the affected area, promoting healing and relieving pain. In addition, the reduction in inflammation can decrease the swelling and discomfort associated with chronic pain.

Research and studies supporting the use of red LED lights for pain relief

Numerous investigations have been carried out to determine the effectiveness of red LED lights in alleviating pain, and many have yielded encouraging outcomes.

One study [1] showed that a red LED light lamp is easy to use, safe, and effective in reducing chronic back pain by 50% in six weeks. Except for malignant hyperthermia and scleroderma, there are almost no conditions for which it cannot be used, and the risk of thermal injury is low. To minimize the risk of such injuries in case of contact with the skin, an automatic shutdown system is provided.

Likewise, another report [2] published in the Journal of Neuroinflammation in 2020 discovered that red LED light effectively reduced pain and inflammation in patients afflicted with knee osteoarthritis.

Types of chronic pain that can be relieved by the therapy

Here are the types of chronic pain that can be relieved by red LED light therapy:

  • Back pain

Therapy can improve blood circulation and reduce inflammation, which leads to a decrease in pain in the affected area.

  • Arthritis pain

Red LED light decreases inflammation and promotes tissue repair, which leads to increased mobility in people suffering from arthritis.

  • Neuropathic pain

Light treatment can stimulate nerve regeneration and reduce nerve spasms, leading to improved symptoms in people with neuropathic pain.

These are not the only chronic pain conditions that can significantly impact a person’s quality of life and make it difficult to perform daily tasks. Red LED light therapy offers a potential alternative for those seeking pain relief without the negative side effects of medication. However, it is essential to consult with a healthcare professional before starting any new treatment regimen.

How to use red LED lights

As a reminder, red LED lamps work by emitting light of a specific wavelength that penetrates the skin and stimulates cellular activity, promoting healing and reducing inflammation. However, to use them safely and effectively, it is important to understand the correct application technique.

Different ways to use the lamps

There are several ways to use red LED lights, including handheld devices, panels, and wall-mounted lamps. Handheld devices are effective for spot pain relief, such as treating joint pain, while full-body models provide a more comprehensive result and treat widespread pain in large areas.

The ideal duration and frequency of light therapy sessions

The ideal duration and frequency of red LED light sessions depend on the patient’s pain status and overall health. It is recommended to consult a healthcare professional to determine the best plan for your individual needs.

In general, daily red LED light treatments lasting 15 to 30 minutes can help relieve chronic pain. However, it is helpful to start with shorter sessions and gradually increase the duration and frequency over time to avoid any adverse reactions.

Precautionary measures

Although this type of therapy is generally safe, some precautions should be taken before starting treatment. It is recommended that you avoid direct gazing at the red LED light and wear protective goggles if necessary. The lamps should also not be used on areas with active infection, cancerous tumors, or areas where you have recently had radiation therapy. It is essential to make sure that the red LED devices are of high quality and emit the correct wavelength for pain relief. 

Other benefits of red LED light therapy

In addition to its ability to relieve pain, red LED light therapy has many potential benefits. It improves skin health by minimizing the appearance of acne, wrinkles, and scars. This is because red light promotes the production of collagen, which is vital for improving skin elasticity and mitigating the signs of aging. It also helps to heal wounds and reduce inflammation. 

Moreover, red light therapy can improve mood and sleep quality. It is believed that light therapy can trigger the production of serotonin, which is a neurotransmitter responsible for regulating sleep and mood. This is especially useful for people suffering from depression, anxiety, or insomnia.


So, red LED light has emerged as a promising alternative method for relief. With its ability to penetrate the skin and stimulate cellular activity, it promotes healing and reduces inflammation, making it a potential solution for chronic pain sufferers. Moreover, it has been found to have other benefits such as improving skin health, mood, sleep quality, and wound healing.

The ideal duration and frequency of red light sessions may vary depending on the individual’s pain condition and overall health. It is also essential to take precautionary measures and consult with a medical professional before starting any new management therapy or treatment plan.
