What is Blue Light Therapy?
Blue light therapy is a branch of alternative medicine that uses natural, (non-laser) blue light to cure, treat, or prevent unwanted health conditions.
Blue light therapy works in different ways to treat different things. In the case of MRSA treatment, it works by killing bad bacteria.
Blue Light Kills MRSA Superbug
Recently, important studies have been consistently showing that two of the most common strains of MRSA can be virtually eliminated through simple exposure to blue light.
Though fewer than 5 percent of MRSA strains can be killed by penicillin and 40 to 50 percent of MRSA strains have become resistant to antibiotics, they appear to have no resistance to blue light, which is free of UV radiation.
Since blue light kills harmful bacterial naturally, safely and without dangerous side effects, blue light therapy has already received FDA approval for the treatment of periodontal disease and acne.
A Blue Light MRSA Study Explained
In this study, an average of 90.4% of both US-300 (community acquired) and IS-853 (hospital acquired) strains of MRSA were killed within minutes of exposure to simple blue light. This should be all over the national and world news. Why isn’t it? Maybe people don’t know what it means.
Here is what the study said:
“These significant levels of photo-destruction at low dosages indicate that irradiation with 470nm LED light energy may be a practical, inexpensive alternative to treatment with pharmacological agents, particularly in cases involving cutaneous and subcutaneous MRSA infections that are susceptible to non-invasive types of radiation.”
Here’s what it means:
“significant levels of photo-destruction” – an average of 90.4% of MRSA bacteria experienced ‘death by light.’
“low dosages” – simple light was used, not low level laser light, not laser light, and it only took a few minutes of exposure to kill significant amounts of bacteria – 30% dying after just 100 seconds of exposure.
“irradiation” – Light shining on something.Light of any color from any source is actually powerful electromagnetic energy, or radiation, and so light of any color can also be called “radiation.”When you shine any light on something, its being irradiated.It’s not as dangerous or expensive as it sounds.These two girls survive by daily high doses of 405-485nm (blue) ”irradiation.”
“470nm” – blue.That’s it.Click here for a more detailed explanation. A previous study was done with similar results with 405nm light, which is visible violet light, very close to UVA on the electromagnetic spectrum.The actual span of the light used in this case was 455-485nm.Since 405nm also worked, it stands to reason that all wavelengths from 405 through 485 would have the same effect.That is blue light, period.
“LED light energy” – as touched on above, all light is energy, the source does not matter.In this case, SLDs (superluminous diodes) were used, which are just the latest advancement in LED lighting – nothing special.LEDs are commonly used in medical research because they largely eliminate the factor of heat.Any blue light source that peaked around 470nm should have produced the same results.
“practical, inexpensive alternative to treatment with pharmacological agents” – easier and cheaper than drugs.They did not mention it’s also 100% natural, having no adverse side effects reported, non-invaisive, painless, simply administered at home… and it’s worth double mention – easy to obtain, easy to use, and very cheap.
“cases involving cutaneous and subcutaniousMRSA infections that are susceptible to non-invasive types of radiation.” – cases of MRSA infections on and just beneath the surface of the skin, where the light is able to penetrate naturally.
Since simple blue light killed an average of 90% of MRSA bacteria in the lab, it may turn out to be a practical, inexpensive alternative to treatment with drugs for cases of MRSA infections of or just under the skin in humans.
Further Research Supporting Blue Light Therapy for MRSA Treatment
I would not wait for further studies, FDA approval, or fancy marketing before I tried this out on myself or a loved one battling a MRSA infection on or just under the skin.
The antibacterial properties of blue light have been known for quite some time – in fact the FDA approved blue light to kill acne bacteria in 2002. There are many “acne treatment lights” already available and in use today containing the same wavelengths used to kill MRSA, it would be very simple for them to be re-purposed immediately in the case of a MRSA infection of the skin not responding to antibiotics. It would also be good to have one of these lights around to disinfect everyday cuts, burns and bites as a matter of MRSA prevention.
How to Find the Light You Need at a Price You Can Afford
At the time of this writing, to my knowledge, blue light therapy has not yet been FDA approved for MRSA treatment. As a result, you won’t find in-home devices marketed for MRSA treatment yet. However, an internet search for an “acne light” will turn up many lights that will work for MRSA treatment in all price ranges. Here’s some tips for choosing one:
- Choose blue light only, not red and blue light combined. Blue light is what kills bacteria, and that is what you need right now. Red light is for healing skin – you can take care of that later. You want the full power output of the light to be blue.
- You’re going to find two different styles of lights: small, portable, hand held lights, and large, table top lights, specifically designed for treating your face. Unless your infection is actually on your face, buy a hand-held light so you can conveniently and fully cover any area.
- Do not buy:
- Any product that is disposable. Light therapy should be a one-time investment.
- Any light that requires replacement heads. High quality products should not need to be frequently replaced.
- Any light that requires replacement batteries, like a flashlight. Recurring expenses don’t make sense.
- Any light that relies on any type of topical substance for its effectiveness. Blue light works all by itself.
Understanding Blue Light Wavelengths
What makes one blue light more effective than another against MRSA is it’s wavelength. Wavelength is the scientific measurement that, when translated into practical terms, means “color.”
The studies referenced in this article prove that blue light with peak wavelengths of 405 nm and 470 nm are effective against MRSA bacteria. What are the differences, and how do they affect your treatment?
|The Differences Between 405 and 470 nm Blue Light|
|LED Peak Wavelength:||405 nm||470 nm|
|Wavelength / Energy:||Shorter wavelength / higher energy||Slightly longer wavelength, slightly less energy|
|Effectiveness:||More effective||Less effective|
|Penetration ofSkin:||Surface only||Penetrates the skin slightly deeper|
|UV Content:||Likely almost 1/2 UVA content||Likely zero UVA content|
