Red Light Therapy MN
Discovered by NASA, red light penetrates to the bottom of your skin’s dermis layer and directly to the fatty layer. Red light stimulates your Mitochondria to regenerate and heal.
Most people have heard of nutrient deficiencies, did you know you could be suffering from a light deficiency? Think of it as mal-illumination. There are 5 bio-active light forms, blue light, UV Light, Far Infrared, Red Light and Near Infrared.
Of course, everyone knows about the importance of vitamin D from sunlight (from UV light). But few are aware that there is another type of light that may be just as vital to our health – red and near-infrared light (also referred to as photobiomodulation.)
There are now over 3,000 peer-reviewed scientific studies showing incredible health and anti-aging benefits of red light therapy and near-infrared light therapy, proving that they can help you:
- Fight skin aging, wrinkles, and cellulite.
- Overcome fatigue and improve energy levels
- Rid your body of chronic inflammation
- Fight the oxidative damage that drives aging
- Increase strength, endurance, and muscle mass
- Decrease pain
- Combat hair loss
- Build resilience to stress at the cellular level
- Speed up wound/injury healing
- Combat some autoimmune conditions and improve hormonal health
- Optimize your brain function and mood
It is recommended to have 3 treatments a week for the first few weeks, after which maintenance sessions can be done once or twice a week.
What Is Red Light Therapy And Near-Infrared Light Therapy/Photobiomodulation? Red Light Therapy MN
Red and near-infrared light are part of the electromagnetic spectrum, and more specifically, part of the spectrum of light emitted by the sun (and also the light of fires). These wavelengths of light are “bioactive” in humans. That means that these types of light literally affect the function of our cells.
If you pass white light (like sunlight) through a prism, it will separate out the different colors based on their wavelengths. This is how we get rainbows as well, and you might remember this from school with the acronym ROY. G. BIV, which stands for red, orange, yellow, green, blue, indigo, violet.
A tiny part of this spectrum – from roughly 400nm to 700nm – is visible to the human eye.
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, from about 700nm to a little over 1,100nm.
It is the red and near-infrared wavelengths specifically that have these amazing effects on our bodies. (Interestingly, even within that range, not all the red and near-infrared wavelengths seem to be created equal. Specifically, most research showing benefits of red light and near-infrared light have used wavelengths in the narrow ranges of 630-680nm and 800-880nm.)
While most other wavelengths of light (such as UV, blue, green, and yellow light, etc.) are mostly unable to penetrate into the body and stay in the layers of the skin, near-infrared light and red light are able to reach deep into the human body (several centimeters, and close to 2 inches, in some cases) and are able to directly penetrate into the cells, tissues, blood, nerves, the brain, and into the bones.
Once in those deeper tissues, red light and near-infrared (NIR) light have incredible healing effects on the cells where they can increase energy production, modulate inflammation, relieve pain, help cells regenerate faster, and much more.
Two Key Mechanisms of NIR And Red Light Therapy
I generally think of photobiomodulation as having two central mechanisms in how it benefits cellular function and overall health:
- Stimulating ATP production in the mitochondria through interacting with a photoreceptor called cytochrome c oxidase.
- Creating a temporary, low-dose metabolic stress that ultimately builds up the anti-inflammatory, anti-oxidant and cell defense systems of the cell (known as hormesis, which is also a primary mechanism of why exercise works).
Mechanism #1: Stimulating Mitochondrial Energy Production
Researchers have found that one specific mechanism of near-infrared and red light therapy is that these wavelengths of light are able to penetrate into cells and activate the mitochondria, directly leading to increased cellular energy production. Many lines of research indicate that the mitochondria are the key player when it comes to the mechanism of how red and near-infrared light affect our cells. 
This point deserves special attention because a huge amount of research in the last decade points to the mitochondria as being critical to health, disease prevention, energy levels, and longevity. The mitochondria are the batteries that fuel all the processes of our organs; thus, things which enhance the mitochondria translate into more cellular energy inside the cell, which allows the cell or organ (e.g. brain, heart, liver, skin, muscles, etc.) to work optimally.
When it comes to red/NIR, the photo acceptor cytochrome c oxidase in our mitochondria is of particular importance.
Cytochrome c oxidase is part of the respiratory chain in our mitochondria that is responsible for producing ATP (cellular energy). When red and near-infrared light photons hit the photoacceptor cytochrome c oxidase, it helps the mitochondria use oxygen more efficiently to produce ATP.
NO, plays many vital roles in the body, but when we have too much of it, too much in the wrong place, or when our cells don’t have the antioxidant capacity to quell the buildup of NO, it can hinder ATP from being manufactured in the mitochondria. 
Well, nitric oxide begins to compete with oxygen in the mitochondria.
In fact, N.O. binds with cytochrome c — preventing it from binding with oxygen. It basically blocks the oxygen from being used by the mitochondria. Because of this, the NO inhibits efficient ATP production.
Therefore, in unhealthy cells, nitric oxide prevents cytochrome c from getting enough oxygen molecules. This hinders ATP production, which is a recipe for poor mitochondrial function, and thus, poor cellular function.
As shown by several research groups around the world, red and near-infrared light essentially prevents this pairing of NO with cytochrome c oxidase. It knocks the NO out and lets the oxygen in!
In essence, photobiomodulation allows oxygen into the mitochondria (and prevents NO from halting energy production).
This boosts mitochondrial function and helps improve the health of every organ and system in our body.
Mechanism #2: Hormesis Red Light Therapy MN
Another key mechanism for how near-infrared and red light therapy work is through hormesis. Hormesis is the process by which a transient metabolic stressor stimulates adaptations that actually improve health. This may sound like an odd concept at first, but you’re more familiar with it than you realize – exercise is a type of hormesis. Exercise works by transiently creating metabolic stress – stressing out the body (workouts are hard work!) and temporarily increasing reactive oxygen species, a.k.a. free radicals – and then in response to that stress, the body adapts to it with things like improved cardiovascular efficiency, improved blood delivery to the muscles, and by strengthening and growing the mitochondria. It also involves downregulating the genes involved in chronic inflammation and oxidative stress (two keys drivers of aging and disease) and upregulating the genes involved in energy production and the internal cellular antioxidant defense system.
The mitochondria get temporarily stressed in a way that causes them to send signals back to the nucleus of the cell (which contains your DNA), and these signals are literally used by the nucleus to determine what genes should be expressed. This is called “retrograde signaling.” It’s a remarkable phenomenon because most people think that our genes do all the dictating of what happens in our cells. In fact, mitochondria generate signals (based on the environment) that signal back to the nucleus which genes to switch on and off!
In particular, the transient increases in ROS (free radicals) from red/NIR light activates many of the same cell defense systems that exercise does. The transcription factor NF-kB is activated through exposure to free radicals generated by red and near-infrared light, which promotes a very low-level inflammatory response. This then engages a mechanism called the NRF2 pathway and the Antioxidant Response Element (A.R.E.) – our internal cellular antioxidant defense system – which helps put out the fire by eliminating the inflammation and free radicals. In short, in much the same way that exercise builds your muscles stronger by temporarily stressing them, light does the same thing to our internal anti-oxidant and anti-inflammatory defense system. It helps make your cells more tolerant to stress, combats inflammation, helps prevent the buildup of free radicals, and ultimately makes your cells healthier, more energetic, and more resilient.
It turns out that humans actually need some of these low-level stressors in their life. The absence of these stressors actually sabotages our health.
Light serves as transient low-level stress to your cells. The end result of these cellular adaptations to the temporary stress is healthier cells that produce more energy, have a stronger anti-oxidant and anti-inflammatory defense system, and are more resilient to overall stress.
So near-infrared and red light therapy is also a form of hormesis, and benefit the mitochondria by creating a low dose stressor that the body then adapts to by becoming even stronger – the body increases the production of internal antioxidant and anti-inflammatory systems, and builds up the size and strength of mitochondria.
In this way, red/NIR light becomes a powerful tool that doesn’t just temporarily alleviate symptoms (like say, an anti-inflammatory or painkiller drug), but it stimulates your body making lasting adaptations at the cellular level that lead to more resilience against stressors and a greater capacity to produce energy.

Blue Light and Its Health Impact
In our modern society, many people get too much blue light from electronic screens, but in nature, you would be getting a natural dose of blue light from the sunrise. Blue light serves to “wake you up” as it sets your circadian rhythm because this frequency produces natural melatonin. Blue light works to produce melatonin but it doesn’t work to release it, the release of melatonin is triggered by the more red light frequencies we would naturally get in the evening. Overexposure to unnatural blue light is the reason many people have trouble sleeping, in modern times. When you stare at blue light screens from electronics right up until bedtime, the brain chemistry works to keep you awake.
This is why it is important to wear blue light blocking glasses starting in the late afternoon until bedtime when using screens or using blue light frequency LED lights in your home. As an alternative, you can consider installing blue light blocking/reducing apps on your devices, such as phones, TVs, computers, ipads, etc. Ideally, you would not be staring at screens before bed, but if you must have screen time, take heed to protect your circadian rhythm and your melatonin release. You will also be protecting your eyes from being damaged by excessive blue light.
Some popular blue light apps include F.lux, Twilight, or Iris, if you download these apps it will make your screens more red before bed.
Realize that when speaking of Blue Light LEDs they are not blue bulbs, what is meant is that they emit too much blue light spectrum that interferes with our circadian rhythm. CFLs also have this problem but CFLs have the added problem of hazardous waste because they contain an amount of mercury that is damaging to the body, especially the lungs when broken. CFLs should be disposed of as Hazardous Waste. I never recommend anyone buy CFL bulbs, especially if you have children!
Safe bulbs in descending order; Incandescent – are the safest and are often warmer in color(more red). LEDs can have a flicker effect which can cause seizures in people with epilepsy and can lead to other neurological effects, over time, in otherwise normal individuals.
If you must buy LED’s buy the warmer colored bulbs. CFLs are TOXIC and they may save you some money on your energy bill, but they are far from being environmentally sustainable with the mercury they contain and the excessive blue light frequencies they emit. CFLs can lead to migraine headaches and other conditions in many people.
