810 Nanometer Wavelength Health Benefits/Effects Cheatsheet

This blog post is a cheatsheet on the 810nm health benefits. The context of how to interpret the 808/810nm studies is also explained

810 Nanometer Wavelength Health Benefits/Effects Cheatsheet
On this page
Introduction

Welcome to the blog post on the effects of the 808 nanometers (nm) and 810nm red light therapy. These wavelengths are located very close together.

But let's first take a step back. From a physics standpoint, all light has wavelengths. Blue light, for instance, can be found between 400 and 500 nanometers, depending on who you ask. Today I'll talk about near-infrared light and two wavelengths precisely: 808 and 810nm light.

All wavelengths have different effects. In the blog I wrote about blue light therapy and green light therapy, for instance, you'll find blue light can help with skin conditions, mood, sleep, dental health, and more. This log is similar about 808/810nm light and wavelengths around them.

Why?

Well, many people using red light therapy or thinking about using it ask me "what benefits does 810nm have" or "what effects can I expect from 808nm red light therapy?" So I decided to compile all the effects of these wavelengths, both benefits and downsides

For this blog post, I've gone through almost 1,000 studies and categorized all of them according to their evidence.

You can view the summary of that 810-nanometer wavelength health benefits cheatsheet below. I've also added a summary of the outcomes of the most important human and animal research.

During this process, I divided all evidence into 1) human; 2) animal; 3) in vitro and ex vivo research. The latter you can understand as lab research that you'd do in chemistry class in high school.

Now, what's important here is that most weight is given to human research. Usually, medicine strongly favors human research because its outcomes are easier to generalize to us humans.

With animal research, such as on rats or mice, positive or negative results don't always translate into similar outcomes in humans. Nevertheless, lessons can often be learned and a link between the outcome and physiological implications can be found.

About 900 studies were included in this process on wavelengths between 805 and 815 nm. I've chosen for that interval of 10nm between 805 and 815 for two reasons: 1) it's likely that wavelengths such as 808 and 810nm have very similar effects; 2) in red light therapy products, light is rarely emitted extremely precisely around just one wavelength - Alex, therefore, tests whether companies have their LEDs put out light with a 5nm difference below and above the marketed wavelength.

Arguably, the 830nm wavelength has different effects from the 810nm wavelength, although not every researcher agrees. Therefore, I've added some advanced comments on these outcomes at the end of this article. I'm fully aware the average person doesn't care much about the philosophical discussions about interpreting medical science - the average person wants to merely know the red light therapy benefits that exist

Also, a massive shoutout to Vladimir Heiskanen for making it possible to create this cheat sheet. I've used Vladimir's datasheet on 7,000+ red light therapy studies as the basis of my work here. Without Vladimir's work, creating this cheat sheet would have taken way more time, and I'd probably never begun working on it.

When you see the cheatsheet below, all studies are categorized according to strong evidence (3+ studies with 65%+ positive outcomes, neutral (in between), and negative (3+ studies with 65% negative outcomes). Again, if you'd like to learn more about these choices, read the advanced comments section at the end of this article.

Below you'll find a summary with the most critical outcomes of mainly the 808/810 wavelengths (range 805 -815nm as I presume their effects overlap).

Each study is numbered from #1 - #899. For each study, the wavelength in nanometers is added. You can click that link to end up with the study in your browser. I've also added information on whether the outcome is positive, negative, or neutral, and whether it's a human, animal, or "in vitro" (lab-based study) for each numbered study.

Also, if it's all too complicated for you, I apologize.

I've tried to tell the whole story regarding the benefits of these wavelengths without oversimplifying. If you're overwhelmed, just read the section on the benefits in humans that have strong evidence, you'll get the basics. And for nerds, there's a lot more data they may love.

Next up, fasten your seatbelts as here we go:

Summary And Table Of Contents:

Strong Evidence For Health Benefits: 3+ Human Studies With 65%+ Positive Outcomes:

  • For the brain, Alzheimer's Disease, opioid addiction, brain injuries such as traumatic brain injury, and depression.
  • Carpal tunnel syndrome.
  • Arterial restenosis (narrowing of blood vessel after a stent in an artery).
  • Dermatitis (skin inflammation) after radiation exposure.
  • COVID-19 infection recovery.
  • Generalized health improvements after exercise and muscle spasms.
  • Bell's Palsy in the nervous system (inability to control facial muscles around the mouth).
  • Many oral health benefits. Benefits are found for mouth ulcers, hypersensitivity of the teeth, postoperative symptoms after oral surgery, the ability to chew, the nerve in your chin, inflammation of the mouth and cheeks, pain during orthodontics, and pain of the tissues around teeth after surgery.
  • Back pain.
  • Wound healing after clinical-grade burns (such as second and third-degree burning stages).

Some Evidence: 1-2 Human Studies Either 100% Positive Or 50-50% Positive/Neutral:

  • A list of 59 benefits that's too long to summarize here. All these benefits either need more research for confirming the benefit is real. With more positive studies, these benefits will move to the "strong evidence" section in the future.

Insufficient Or Neutral Or Conflicting Evidence - Therefore Not Be Included In The Other Categories Of Human Evidence:

  • A list of 47 outcomes in total that are too long to summarize here. Current evidence is that 805-815nm light has no effect on these benefits or that more research is needed to clarify the outcomes.

Strong Evidence For Health Harm: 3+ Human Studies With 65%+ Negative Outcomes

  • Stroke in the brain. (note: does not cause a stroke. If you want to know the implications and context then read the studies that are cited)
  • Muscle Fatigue
  • Root resporption of teeth, when there is damage to a tooth

Stong Animal Study Evidence: 3+ Animal Studies Available And 65%+ Positive

  • These results need to be proven in humans to be sure there is an effect
  • Arthritis
  • Bone repair, health with implants, and aging.
  • Epilepsy
  • Exercise
  • Hearing loss
  • Muscle injuries
  • Sciatic nerve injury, which is a nerve going from the spinal cord to your legs, through the lower back.
  • Oral health, jaw expansion in orthodontics, the tissues around the teeth such as gums, salivary glands (that create the saliva in your mouth, and the reinsertion of teeth through surgery.
  • Neuropathic pain (better known as nerve pain).
  • Different lung injuries, such as from blood poisoning and other toxins (LPS).
  • Wound healing for burns, diabetes, and cuts (such as excising during surgery)

Insufficient Or Neutral Or Conflicting Animal-Based Evidence - More Research Needed

  • A list of 76 potential benefits that's too long to summarize here. More animal research will show whether there is strong evidence for these potential benefits or not.

Animal-Based Evidence For Health Harm: 3+ Studies With 65% Or More Negative Outcomes

  • No studies in this category. If you're a nerd, read why in the advanced section of my comments at the end of this blog post.

In Vitro Studies

  • The term literally translates to "in the glass" studies.
  • Not to be taken too seriously for any clinical relevance or implied benefits but interesting for nerds who want to understand the complete picture of the science.
  • 12 benefits have exclusive in vitro evidence with 3+ studies and 65%+ positive.
  • 46 benefits have insufficient evidence or neutral outcomes.

Again, if you'd like to learn more about my thought process about my choices, read my advanced comment section at the end of this blog post.

I've also created a section with the best panels with 808/810nm light outputs.

Finally, there's the conclusion.

805-815nm Human Evidence Outcomes (Mostly The 808 & 810nm Wavelengths)

Obviously, human studies are by far the most valuable in this process. If you focus on only one section, check the benefits listed here. And make sure to consider both the positive and negative outcomes - both are proven effects.

For the neutral/conflicting section, you'll have to check why the outcome is as is. Sometimes there are a roughly equal number of positive and negative outcomes. Sometimes there is simply not enough evidence.

Strong Evidence For Health Harm: 3+ Human Studies With 65%+ Negative Outcomes

Note: please do read the studies associated with the topic to understand the context. It's doubtful that 810nm includes a stroke or causes muscle fatigue. The studies probably concern recovery after a stroke that's not improved by 810nm light. I cannot be responsible for giving commentary on almost 900 studies. Hence, it's your responsibility, the reader, to click on the studies and read them to understand the context. Don't draw conclusions based on these studies without having read them.

805-815nm Animal Study Evidence Outcomes (Mostly The 808 & 810nm Wavelengths)

I'm fully aware of the philosophical differences that exist regarding animal-based research. I believe that animal-based research offers lots of value in absence of human studies but I'm aware not everyone agrees here.

Some people ignore all evidence unless multiple RCTs with humans are available. If you're such a person, just ignore this section. If you do consider animal research very valuable like me, then enjoy:

Advanced Comments On The Outcome Of These 808/810nm Wavelength Of Red Light Therapy Studies

In this section, I'm digging deeper into some advanced comments based on the outcome of this cheat sheet. You'll need a bit more medical research background to understand these comments. But here we go - for the nerds among us:

  • I didn't separate human and human RCT research. For the best results and if time allows, I might update this article. Methodically it would be slightly better to give Randomized Controlled Trials (RCTs) a higher ranking than regular human research.
  • No systematic reviews were included either. There's a good reason for that as this study aims to be a sort of systematic review of all the published literature on this topic of wavelengths.
  • The 65% positive and 65% cutoff points aren't justifiable on hard logic, of course. Higher or lower percentages both come with their upsides and downsides, as each scientist can imagine, just like the p-value in scientific research and power analyses.
  • Creating the "perfect" categories is really difficult and could be even more granular. For instance, what happens when human research shows these wavelengths are beneficial while animal research shows there is no benefit? Once more, there is no easy answer here!
  • If a study is positive or negative, you cannot tell why at first value. Some outcomes would be beneficial or detrimental if other treatment parameters were used, such as a lower or higher power output in mW/cm2, a longer treatment time, or a pulsed instead of a continuous laser. This document only shows what studies are positive not why that is the case.
  • The fact that there are no negative animal and in vitro studies published can have several reasons. For instance, there can be publication bias or researchers might no longer investigate topics after they've found one published negative study emerges. Another explanation for this outcome is how Vladimir Heiskanen categorizes the outcomes of these studies as either positive, neutral, or negative.
  • Some studies are included that aren't entirely relevant. Examples are in vitro research in candida and safety studies of red light therapy and/or LLLT. I included them anyway to assure you that all studies between the 805-815nm wavelength interval have been included.
  • I've removed studies with polychromatic light. An example here is an incandescent light bulb that emits light from the UV range all the way to the far infrared range - very little light is emitted at the 805-815 range there.
  • I'm aware of the differences in the interpretation of wavelengths across researchers. Right now, I believe that 810nm has significantly different effects from 830nm, for instance. But some researchers in the field think that the effects of 808 or 810nm light are roughly the same as 850nm. I don't fall in the latter camp.
  • I understand that this amount of information is somewhat overwhelming. And yet, it makes me happy to know that people can finally see the complexity of this topic. So anytime you see any website stating that 810nm has benefit for skin health, brain disease such as Alzheimer's, and athletic performance, they are grossly oversimplifying. Of course, I understand that companies need to market and sell products and that customers don't care about extremely complex information but if you're a nerdy person like me, you also want to offer customers the truth, whole truth, and nothing but the truth.
  • I haven't ventured into the topic of how wavelengths interact or overlap. For instance, can you get similar effects from 830nm light as from 810nm light? I'll have to check more comparison studies on wavelengths to answer here. I doubt the effects of wavelengths so far apart strictly overlap, but I could be wrong, as some companies in the red light therapy space now claim that the effects of all red and all near-infrared wavelengths are roughly the same.
  • I'd love to learn what you think about this cheat sheet. Should Alex and I make more of these sheets? Or, should it be done differently and exclusively use human research? Or would you rather know the status of the animal research too? As someone with a Master's degree in health science, I'd rather have animal studies presented to me too, because I think they are valuable - although not as valuable as human research. But, adding animal and in vitro studies is far more time-consuming, I get that.
  • Let me know what you think in the comment section below! I'm aware that other remarks by me on the science or the philosophy of science could be added here!

Best 808/810nm Wavelength Panels

Below I've listed the best red light therapy panels that use high proportions of the 808/810nm wavelengths.

The data is compiled based on the datasheet Alex created from his red light therapy reviews - discount code ALEX saves on almost all of these:

Again, discount code ALEX saves you on most of these as well.

If you're only concerned about brain health, check Alex's Vielight review. You can buy a Vielight on their website and use discount code ALEX10 for 10% off. Some Vielight products, such as the Neuro Alpha or Gamma or Duo emit 100% 810nm light into the brain. These are highly recommended if you're focusing on brain-specific benefits that I've mentioned earlier, such as opioid addiction or dementia.

As for red light therapy panels, the LightpathLED or MitoADAPT panels are probably best if you want a huge chunk of light emitted in the 808/810nm region, although, you may want to check the Light Therapy Insiders Shopping Tool for the latest info.

💡
This blog post was initially written during March 2023, so it may not be current regarding the best products. For the latest data on which product emits the most 810nm light, simply filter at the Light Therapy Insiders Shopping Tool for 810nm light, and you'll get heaps of options!

I highly recommend the products listed above if you want to use 808/810nm to the maximum extent. I assume that if you use panels that emit only 830nm and 850nm, you won't get the benefits I consider in this blog post. That principle should be relatively easy to understand although there is sicentific cdebate on that topic.

Video Interview With Science Writer Bart Wolbers

Here's a YouTube interview of me, Bart Wolbers, by Alex Fergus, on this blog post and other findings:

I'll talk specifically about what you can expect about the 810nm health benefits.

Conclusion: The 808nm And 810nm LLLT Wavelengths Have Strong Medical Merit

I hope you enjoyed my very detailed showcase of all of the effects of 808/810 nm wavelengths within red light therapy. If there is substantial interest in this topic, Alex and I can probably justify creating more cheatsheets for different wavelengths, such as 630, 660, 670, 830, 850nm, and other wavelengths.

Hopefully, after scanning this blog post, you'll also understand how complicated this science is. Whenever someone asks you "what 808nm does" or "what the benefits of 810nm light are", the answer is highly complicated. If a company tells you X wavelength has Y benefits and only a few are listed, you can be assured they cherry-picked the data. Cherry-picking isn't always wrong, with marketing, we need to create an easy-to-understand message, but it's not the whole truth and nothing but the truth.

Nevertheless, despite its complexity, I hope this cheatsheet on the 808nm and 810nm wavelengths gives you new insight into the benefits of red light therapy! Now, if someone asks what 810nm does, I can finally send them the full answer...
