About the Brand

Tendlite is a reputable brand specializing in red and infrared light therapy devices designed to address a range of health issues, notably joint and muscle pain, as well as inflammation.

The focus of the company is to offer an effective, safer, and affordable alternative for pain management.

What Are the TENDLITE™ Health Benefits and How Does it Work?

Tendlite's devices offer both red and infrared light therapy, with specific wavelengths of 660nm for red light and dual wavelengths of 660nm and 850nm for infrared light. Each type of light serves a unique therapeutic purpose: red light is effective for addressing surface-level inflammation and redness, while infrared light penetrates deeper into the body for pain alleviation and tissue repair.

A scholarly review by Christos Tsagkaris, Andreas S. Papazoglou, et al., in the European Journal of Investigation in Health, Psychology, and Education, showed that while infrared light therapy effectively reduced muscle pain, its efficacy in facilitating recovery was less pronounced. When activated, the LED light emits photons that stimulate cellular mitochondria, leading to increased synthesis of adenosine triphosphate (ATP). This extra ATP powers the body's cells, promoting robust healing and repair mechanisms, as elaborated in our review of Kala Red Light. It also has the potential to block certain nerve receptors, thus diminishing pain sensation.

A separate study by Kazuhide Inoue, Makoto Tsuda, and Schuichi Koizumi in Purinergic Signalling outlined the critical role that ATP plays in pain perception. Furthermore, light therapy's advantages aren't limited to humans. Craig Froley, President and CEO of Luma-Tech, LLC, emphasizes that light therapy fundamentally enhances blood circulation, encourages cellular regeneration, and decreases inflammation. This makes it beneficial for pets, whether they're household companions or athletic performers.

Supporting this, research by Andrea L. Looney, Janice L. Huntingford, Lauren L. Blaeser, and Sabine Mann in The Canadian Veterinary Journal found that dogs subjected to a six-week course of red light therapy experienced significant relief from elbow arthritis. This comprehensive set of data underscores the versatility and efficacy of Tendlite's light therapy devices, offering a multi-faceted approach to pain management and cellular repair for both humans and animals.

Mitigates Pain in Muscles and Joints

As detailed in our examination of Mito Red Light, LED-based light therapy has been shown to increase cellular ATP production, which in turn mitigates inflammation and deactivates specific pain receptors, thereby alleviating muscle and joint discomfort.

Research by John Foley and David B. Vasily, published in Laser Therapy, indicated that athletes experienced faster recovery times when treated with infrared light therapy [5].

We also reviewed top-performing infrared lamps, noting their effectiveness in pain management, tissue penetration, and inflammation reduction.

Enhances Post-Exercise Recovery

Red and infrared light therapies contribute to faster muscle repair, reduced inflammation, and quicker recuperation after physical exertion, thanks to elevated ATP levels in cells.

A scholarly review by Cleber Ferraresi, Ying-Ying Huang, and Michael R. Hamblin in the Journal of Biophotonics lends credence to the effectiveness of photobiomodulation in aiding muscle recovery

Red light therapy is a type of therapy that uses red or near-infrared light to treat a variety of conditions. During a red light therapy session, a person is exposed to a specific wavelength of red or near-infrared light that is delivered through a light-emitting device. The light penetrates the skin and reaches the cells within the body with a range of therapeutic effects.

Understanding Red Light Therapy

Red light is a type of visible light, Its wavelength falls between approximately 630 and 700 nanometers (nm) on the electromagnetic spectrum. Red light is often used in light therapy treatments for the skin, as it has been shown to have the most beneficial effects on skin cells and collagen production.

Near-infrared (NIR) light, on the other hand, has a longer wavelength than visible red light and falls between approximately 700 and 1200 nm on the electromagnetic spectrum. NIR light is not visible to the human eye, but it can penetrate deeper into the skin and other tissues than visible light, making it useful for a variety of therapeutic applications ranging from wound healing to inflammation reduction or improved circulation, among other benefits.

Different Red Light Therapy devices usually deliver slightly different wavelength ranges that research has shown to be the most effective for the concern they are being recommended for.

Red Light Therapy (RLT)  strengthens the mitochondria, the cell’s powerhouse, where cell energy is created. Adenosine Triphosphate (ATP) is the critical energy-carrying molecule that is found in all living organisms. By optimizing the function of the mitochondria, more ATP is produced and with increased energy cells can function optimally.  

This scientific breakthrough resulted in scientists discovering Red Light Therapy’s ability to stimulate and speed up tissue repair and growth. Red Light Therapy is now widely used for maintaining a healthy complexion, speeding up muscle recovery, reducing inflammation, improving sleep, treating neurological conditions, balancing hormones, treating pain, and even losing weight.

Research has also indicated that Red Light Therapy can help to restore cellular balance and alleviate the negative impact of blue light exposure. The prevalence of blue light in our society has become a growing concern as many individuals spend prolonged periods of time looking at screens on a daily basis.

A Brief History of Red Light Therapy

The journey of Red Light Therapy (RLT) has been both fascinating and impactful, starting from its humble origins in the late 19th century. Dr. Niels Ryberg Finsen, the pioneer in light therapy, made a groundbreaking discovery in 1896 that light could be harnessed to treat Lupus Vulgaris, a form of tuberculosis affecting the skin. His work, which led to the tangible healing of skin lesions, was so revolutionary that he received the Nobel Prize in Physiology in 1903.

Fast forward to 1960, Theodore H. Maiman invented the first operational laser, fulfilling Albert Einstein's theories on the principles of lasers laid out in 1917. This invention opened new avenues for RLT, allowing more precise applications.

NASA took an interest in Red Light Therapy in 1987, conducting experiments to examine its effects on plant growth in space missions. These studies hinted at RLT's potential to benefit not just human health but also broader ecological systems.

In the same vein, Endre Mester's work in 1967 set the stage for modern RLT applications.

His experimentation with low-level laser therapy on skin cancer effects demonstrated the technique's efficacy and led to FDA approval for wound healing in 2002.

The advent of LED technology in the 1990s was a game-changer, offering an efficient and cost-effective alternative to traditional light bulbs. This technological leap made light therapy more accessible to the general public, including its use in sports medicine where physical therapists reported quicker recovery times for sports-related injuries.

One of the most recent and exciting developments in RLT is its potential role in weight management. Studies indicate that Red Light Therapy can influence hormones like Leptin and Ghrelin, which play key roles in regulating appetite and metabolism. This makes RLT a promising avenue for non-invasive weight loss treatments.

As RLT continues to evolve, its applications keep expanding, crossing multiple disciplines from medicine to ecology. Researchers are continuously probing its potential, finding new ways to apply this age-old yet ever-advancing technology.
