If you are experiencing pain, recovering from an injury, have skin conditions, or looking for anti-aging options, red and near-infrared light can help you! Thanks to the scientists of this era who develop new techniques for the well-being of humans, we have access to in home wellness devices. Red light therapy is one of the newest, non-invasive ways to reduce pain and inflammation, repair tissues, and boost collagen production. The concept of red light therapy is emerging for a number of health and aesthetic concerns.


This article explains the concept of red light therapy, how it works, and the benefits of using this technique as complementary therapy.


History of Red Light Therapy

Ancient Egyptians, Greeks, and Romans were aware of the healing properties of sunlight and used sunlight exposure for various health purposes. They recognized the benefits of natural light for wound healing, treating skin conditions, and promoting overall well-being.

In the late 19th and early 20th centuries, Danish physician Niels Ryberg Finsen conducted extensive research on the therapeutic effects of light. Finsen is considered the pioneer of modern light therapy and received the Nobel Prize in Physiology or Medicine in 1903 for his work on light therapy in the treatment of tuberculosis of the skin.


With the invention of electricity, researchers began experimenting with artificial light sources for therapeutic purposes. In the mid-20th century, scientists and physicians started using various types of lamps, including incandescent and fluorescent lights, to deliver specific wavelengths of light for therapeutic applications.


The invention of lasers in the 1960s opened up new possibilities for light-based therapies. Laser technology allowed for precise control of light wavelengths and intensities. Initially, lasers were primarily used for surgical and diagnostic purposes. However, researchers soon discovered the potential therapeutic benefits of low-intensity laser light, leading to the development of low-level laser therapy (LLLT) or photobiomodulation.


Over the years, extensive research has been conducted to investigate the effects of red and near-infrared light on various biological processes. Scientists have studied the mechanisms of action, explored different wavelengths and dosages, and investigated the potential applications of red light therapy in areas such as dermatology, pain management, wound healing, and sports medicine.

With advancements in technology, light-emitting diodes (LEDs) became a popular choice for delivering red light therapy. LEDs offer a safe and efficient way to deliver specific wavelengths of light without generating excessive heat. The use of LED-based devices for red light therapy has become increasingly common in both clinical settings and for at-home use.


There is growing evidence, both in academic and clinical fields, about the effectiveness of red light therapy.


How Red Light Therapy Works

Red light therapy (RLT) comes under the concept of photobiomodulation. Photobiomodulation, also known as low-level light therapy (LLLT) or cold laser therapy, is a form of phototherapy that uses low-intensity light sources, such as lasers or light-emitting diodes (LEDs), to stimulate biological processes in cells and tissues. It involves the application of specific wavelengths of light to targeted areas of the body.


Red light therapy, or broadly speaking, photobiomodulation, uses light of a specific wavelength. Light wavelength ranging between 400nm to 1200nm is usually used for therapy. Specifically speaking, red light ranges between 620nm to 750nm. Light of the above-mentioned wavelength falls in the visible light spectrum.


It has been observed that light of blue, red, and green wavelengths have equal efficiency. Other than the above-mentioned wavelengths, infrared wavelengths longer than 1200nm are also used for PBM therapy. Infrared light is not visible. Moreover, infrared light represents the heat of the body. Infrared treatment is observed to have the same therapeutic effects on the body.


Among all the wavelengths, the red color wavelength is the most popular. Red light therapy has gained popularity of being the best-known and easiest-to-access therapy.

So, how do light waves have a therapeutic effect? When photons of light are bombarded on the skin, they enter the tissue. Inside the tissue, light is responsible for two physiologic effects. First, it triggers the chromophore, which is part of a molecule responsible for its color. Second, it activates the mitochondria. The basic function of mitochondria is to generate ATP, the basic unit of cellular energy. Light photons activate the mitochondria to generate more ATPs. This extra production of ATP is responsible for a lot of therapeutic effects. These effects are discussed in later sections.


In order to obtain the therapeutic effects of red light therapy, you should maintain specific protocols and dosages of light. The specific intensity and dosage of light depend on the strength of light. Our red light therapy pads only need 20 minutes to provide enough energy to stimulate the body's cells. You can apply our red light therapy pads up to 3 times a day to continue to provide healing benefits throughout the day.

One of the most common uses of red light therapy is in cosmetics. People are interested in red light therapy for its ability to boost collagen production. Collagen is most known to assist with skins elasticity, but it's also great to help heal tissues and wounds. When the skin is exposed to specific wavelengths of red light, it can penetrate the skin and reach the deeper layers where collagen is produced. This exposure can stimulate fibroblasts, the cells responsible for collagen synthesis, leading to increased production of new collagen fibers. This means its great for fine lines and wrinkles!


Red light therapy can be used for other cosmetic benefits, such as:

  • Hair growth

  • Reduce acne

  • Erase wrinkles and fine lines

  • Reduce redness

  • Reduce the appearance of scars

Red light therapy's basic function is to boost blood flow and reduce inflammation. By reducing inflammation, red light therapy addresses acne, hair growth, and redness. complementary therapies are also used in combination to gain better results. It also improves the immune system against bacteria responsible for acne.


Red Light Therapy Assists with Sports Injury Rehabilitation

Red light therapy can help accelerate the process of injury rehabilitation in athletes. Sports injuries, such as sprains and strains, are common and can lead to significant downtime for athletes. However, with red light therapy, the recovery time can be reduced, allowing athletes to get back to their game faster.

The process of wound healing is complex and involves various stages, such as hemostasis, inflammation, proliferation, and remodeling. During the inflammation stage, red light therapy helps to reduce swelling and inflammation by promoting lymphatic drainage and decreasing the production of pro-inflammatory cytokines.


Red light therapy also stimulates the growth of fibroblasts, which are responsible for collagen production. Collagen is a vital component of the skin and plays a crucial role in wound healing. By promoting collagen synthesis, red light therapy helps speed up tissue repair and regeneration.


Red Light Therapy Eases Pain and Arthritis

Red light therapy emerges as a promising non-invasive alternative for alleviating pain and inflammation associated with arthritis and various painful conditions. Arthritis, a prevalent joint disorder affecting a substantial global population, is characterized by symptoms such as pain, stiffness, and inflammation. While traditional treatments for arthritis typically involve medications, physical therapy, and, in some cases, surgery, red light therapy introduces a novel approach to pain relief and improvement of symptoms.


One of the key mechanisms through which red light therapy exerts its therapeutic effects is by penetrating the skin and underlying tissue. The wavelengths of red and near-infrared light used in this therapy are capable of reaching the mitochondria within cells. Mitochondria are the powerhouse of cells, responsible for producing adenosine triphosphate (ATP), the energy currency of the cell.

Studies have demonstrated that red light therapy stimulates the mitochondria to enhance ATP production. This increased energy production, in turn, has several positive effects on cellular function, including a reduction in inflammation. By mitigating inflammation, red light therapy contributes to the alleviation of pain and stiffness associated with arthritis.


The application of red light therapy is particularly noteworthy in the treatment of osteoarthritis, a common form of arthritis resulting from the gradual wear and tear of joints over time. Osteoarthritis is characterized by the degeneration of cartilage and the subsequent inflammation of the affected joints. Red light therapy's ability to target inflammation and promote cellular repair aligns well with the goals of managing osteoarthritis symptoms.


The non-invasiveness of red light therapy is a notable advantage, especially when compared to more traditional and invasive approaches. Patients may find relief from arthritis-related discomfort without the side effects or recovery periods associated with certain medications or surgical interventions.


In summary, red light therapy offers a promising avenue for managing pain and inflammation associated with arthritis. Its ability to stimulate cellular energy production and reduce inflammation makes it a valuable non-invasive option for individuals seeking alternative or complementary approaches to traditional arthritis treatments. As research in this field continues to evolve, red light therapy holds the potential to enhance the quality of life for individuals grappling with the challenges of arthritis and related painful conditions.
