Red Light Therapy
What is Red Light Therapy?
Red and near-infrared light are part of the electromagnetic spectrum, and more specifically, part of the spectrum of light emitted by the sun. These wavelengths of light are “bioactive” in humans.
At the highest end of the visible light spectrum is red light, which goes from a little over 600nm to approximately 700nm. Above the visible light spectrum is near-infrared (NIR) from about 700nm to a little over 1,100nm.
It is specifically these red and near-infrared wavelengths that have amazing effects on our bodies. Most research showing benefits of red light and near-infrared light have used wavelengths in the ranges of 630-680nm and 800-880nm.
There have now been literally thousands of studies done in both animals and humans. Overall, red and near infrared light has been repeatedly shown to have positive effects on cell function in animal and human studies and aid in improving a wide range of conditions.
Near-infrared (NIR) and red light therapy devices have been FDA-approved for several purposes so far, including hair-loss reversal, anti-aging, acne, wound healing, pain relief, fat loss, and more! This is worth noting because it proves the abundance of research demonstrating benefits – the therapy has to be proven safe and effective in numerous trials in order to gain FDA approval.
It’s all about the penetration…
Most wavelengths of light (UV, blue, green, yellow, etc.) are unable to penetrate into the body - instead they stay in the layers of the skin.
However as the picture below shows, red and near-infrared light are able to penetrate deeper into the human body and are able to reach the cells, tissues, blood, nerves, into the bones and even into the brain!
The benefits of red light: Red light between 600-700nm offer benefits for skin texture and tone, smoothing fine lines and wrinkles, promoting collagen production and generally rejuvenating the appearance of skin and hair.
The benefits of near-infrared light: Near-infrared light (NIR) 700nm - 1100nm. penetrates deeper into the tissues to assist with wound healing, muscle recovery, nerve injury and joint pain.
Red light boosts cellular energy…
The most well studied mechanism of action surrounding red and near infrared light therapy is increased mitochondrial energy production in the cells. mitochondria are tiny organelles that are the energy power 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 photoreceptors 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). Adenosine triphosphate is a complex organic chemical that provides energy to drive many processes in living cells, e.g. muscle contraction, nerve impulse propagation, and chemical synthesis. Found in all forms of life, ATP is often referred to as the "molecular unit of currency" of intracellular energy transfer. When our cells have more energy, they simply perform better and the body follows suit!
The proven benefits of red light therapy…
We'll dive deeper into each of these in future articles, but the proven benefits of red and near infrared light therapy include:
Promotes wound healing and tissue repair
Supports collagen production / anti-aging
Reduces swelling and inflammation (pain)
Improves joint health
Improves physical performance, muscle recovery and energy levels
Increases melatonin / improves sleep
A red light therapy session is 15 minutes and can easily be done on a lunch break. Call us for more info.
Red Light Therapy sessions are included free with all Men’s Health memberships!
