Ⅰ Learn About Red Light Therapy
What is LED Light Therapy?
Red and near-infrared light therapy is also known as PBM (photobiomodulation). PBM involves the use of specific wavelengths of natural light in the mid-600 and mid-800 nanometer range to enhance the health and function of our cells without any harmful UV rays, excess heat, or negative effects.
Light therapy is among the earliest recorded healing modalities. Solar therapy was first used by the Egyptians, and forms of light therapy were also practiced by the ancient Greeks, Chinese, and Indians. No question that light exerts biological effects. Your body needs light to be healthier.
What is the wavelength of WK - K1400 Led Therapy Light?
At WK - K1400 Red Light, our team of leading researchers and engineers believe that light therapy is one of the best-kept secrets for WK - K1400 health and abundant energy. Clinical science has shown us that the wrong type of light can make us sick and tired. But the right type of light can heal our bodies and promote health & beauty.
WK - K1400 Red Light devices allow customers to use the healing power of light to change the way they look, feel, and live. No more expensive clinical sessions or trips to the doctor. You can heal and benefit on your terms, in your own home.
How does LED light therapy Work?
The most well-studied mechanism of action surrounding red and near-infrared light therapy is increased mitochondrial energy production in our cells. Mitochondria can be thought of as the energy production plants of all the cells in our body. Red and near-infrared light therapy helps the mitochondria create more of that energy.
The specific photons found in red and near infrared light interact with a photoreceptor within our cells called cytochrome c oxidase. This interaction stimulates the mitochondria in our cells to use oxygen more efficiently, which allows the mitochondria to produce more ATP (Adenosine Triphosphate, also known as cellular energy, ATP is like the "energy money" for our cells. After exercise or when cells work, they need ATP, just as we need money to shop).
During the LED light therapy treatment, chromophores within our cellular mitochondria absorb red and infrared light photons and convert them into energy. Once this red light energy has been absorbed by the body, it is then used by the cells to build new proteins such as collagen and elastin and to assist with cellular regeneration. When our cells have more energy, they perform all of their functions better. When our cells are functioning optimally, our bodies function optimally.
What are the benefits?
- Reduce Inflammation: Near-infrared (NlR) light reduces overall inflammation in the body by decreasing the presence of inflammatory markers. This reduction can help ease the symptoms associated with joint pain, sore muscles, autoimmune diseases, arthritis, traumatic brain injuries, and spinal cord injuries.
- Improve Circulation: In many studies, LED light therapy has been clinically proven to increase the diameter of blood vessels and to improve circulation. What's more, LED light therapy also protects red blood cells against oxidative stress and limits platelet loss during surgical procedures.
- Reduce Recovery Time: For high-performance athletes (and those who train like them), LED light therapy can help accelerate muscle repair following fatigue and injury. Mitochondria within cells are particularly responsive to LED light therapy, and muscle cells are exceptionally rich in mitochondria. LED light therapy may also stimulate stem cells, further assisting in muscle recovery.
- Promote Healthy Cellular Function: The most significant benefit of LED light therapy is the effect it has on the body's cells. One of the most critical outcomes of LED light therapy on cellular function is the stimulation of collagen production. Collagen strengthens hair, is responsible for the health of connective tissue, and provides our skin with firmness and elasticity.
- Stimulates Hair Growth: Alopecia, or hair loss, is a common disorder affecting 50% of males over the age of 40 and 75% of females over 65. Studies have shown that LED light therapy can stimulate hair growth. Red light wavelengths are believed to stimulate epidermal stem cells in the hair follicle, shifting the follicle into the anagen (active growth) stage.
- Improve Skin Health: LED light therapy can dramatically transform the skin. Red light wavelengths, in particular, target the mitochondrial chromophores within skin cells, generating the production of collagen proteins. Collagen stimulation yields more holistic and enduring benefits than simply resurfacing the outer layers of the skin. Stem cells may also be activated, increasing tissue repair. The result is accelerated healing and wound repair, improved appearance in hypertrophic scars, reduction in fine lines and wrinkles, and improved skin texture.
- Increased fertility: Around the age of 30, male testosterone levels naturally start to decrease. Men who hope to achieve a natural boost to their sex drives, sexual satisfaction, fertility, and physical performance can reap benefits from LED light therapy. Red and near-infrared wavelengths can stimulate photoreceptor proteins in the testes, causing higher testosterone production. Other studies have theorized that low-level light therapy may affect the pineal gland in the brain, which bears a significant impact on reproduction.
- Reduce Pain: In a clinical study, neuropathic pain caused by a spinal cord injury was dramatically reduced by the application of red light treatment. Near-infrared light wavelengths reduce overall pain by easing joint stiffness and soreness, diminishing inflammation, easing muscle spasms, and enhancing blood flow.

NASA's LED Light Therapy Research: NASA developed LED near-infrared technology to address muscle and bone health issues in astronauts. Their research has demonstrated that infrared light at specific wavelengths (680, 730, and 880 nm) can stimulate cellular energy processes in mitochondria, promoting wound healing and improving muscle and joint health. This foundational work supports the idea that near-infrared light, including the 850 nm wavelength, can benefit both skin and tissue health by enhancing cellular functions.

Veterans Affairs (VA) Study on Brain Health: The VA is conducting a study using red and near-infrared light (NIR) therapy for Gulf War veterans, investigating the potential cognitive benefits. They are examining how NIR light improves blood flow and boosts nitric oxide production, which could aid in recovery from brain-related issues and may also support wound healing and pain relief for muscles and joints. This clinical study highlights the relevance of NIR for deep tissue benefits and is part of ongoing efforts to explore the effects of infrared light beyond skin health.

How do you tell if NIR is functioning?
As NlR is invisible to the human eye, it seems as if no light is emitted when NlR is started. But if you focus your cell phone camera on the light, you will see some faint purple light glowing. So you can tell whether NlR is functioning by this method.
