The power density is irradiance.

Actually laser does not penetrate deeper. Depth is dependent on two things, wavelength and dose. The higher the dose with the ideal wavelength produces the ideal result.

Which red physio lamp? Some of them are quite hot.

@@curtisturchin3416 the red bulb thing. It's hot when you are close but can you verify that there are also benefits just being in a room with it on?

The dose is the important issue. For example, if you have a headache, is 1/10 of aspirin going to do anything? Probably not. Will there be benefit due to the miniscule exposure? probably not therapeutic but not harmful.

Studies show even just treating the brain provides the same benefits as full body treatrments. The main thing in choosing a unit is to buy one that is powerful. Low dose units take too long to be used on a regular basis.

What staerted/caused it? Toxic exposure, antibioitcs, chemo, radiation, frostbite, diabetes, etc?

Everything I say is based on data. But most people just want the facts and do not want me to list journal citations for everything. If you wajnt date for something let me know. EmaIl me as I cannot load attachments here.

No, sorry. During Covid I stopped teaching and got so busy, I have not picked it up again. Might start again in about one year. I have spent time in Vancouver, Vancouver Island, the Rockies and in and around Toronto. Where are you? Curtis

@@curtisturchin3416 - I’m 45 min west of Toronto midway towards Niagara Falls

@@curtisturchin3416 - my company has a startup establishing Light Therapy clinics for Dr og ailments.

Yes, you can. If you have bandages, use the light around the perimeter of the bandage. The light will expand as it penetrates. Use lower doses multiple times per day.

Technically that is true. But most IR devices appear to somewhat red as well. Let's face it, that is easier for people's brains. They are not technical.

Red and Infrared light therapy.

@@curtisturchin3416 thanks so much ,I just bought a lifepro Biloxi wand to use on my dog that has bad arthritis pain . I pray it works 🙏

The one with the most optical power. Even the right wavelength, if underpowered, is ineffective.

B

Sure, as long as it has sufficient power.

Which unit do you have? How many milliwatts?

​@@curtisturchin3416 I have a Platinum Led Biomax 450, spec say 180mw/cm2. I have been using it for extended duration, I usually do 10-15 minutes front body, 10-15 minutes back, 5-10 minutes back of the neck, 5-10 minutes forehead (while covering eyes), 5 minutes eyes from far away (while closed), and sometimes 5-10 minutes of mouth and teeth. When I do the forehead and back of the neck, I try to be as close as comfortably possible. I have noticed improvements in all areas, even my vision has improved. I don't feel any bad side effects but after watching your videos I am concerned that I might be overdoing it, are there any serious dangers and what are they?

It is not dangerous but to be really effective, treat the carotid arteries and the gut instead of doing more on the forehead.

@@curtisturchin3416 Thank you for the insight. I would love to see more long form content from you, there are very few experts on this and you seem super knowledgeable.

@@tsotnetunes Good suggestion. In about one month I will start producing a new video every week. I just have been way too busy. Thank you!

Studies have shown that the largest artery is the aorta, second largest is the carotids. This takes the blood into the Circle of Willis where it is distributed to a vast amount of brain tissue.

That is NOT true. The FACT is that all wavelengths need direct skin contact for MAXIMUM penetration. The inverse square law clearly shows that the farther away you move from the skin the less penetration there is. But, you need to stay above the skin with an infected wood or some other type of skin infection.

That is correct. Also, 980nm is used to target a different chromophore (water), which is another mechanism involved in PBM. See doctor Gerald Pollack and his book ‘the fourth phase of water’.

@@imperfectillustration6261 But 980 has a problem. In higher doses it gets hot. So doses must be lower, so it is MUCH slower to get physiological results.

Then which wavelength is best or good for no contact?

Donna - what type of problem are you treating and what is your treatment time and frequency? What does it smell like? How old is your unit? Curtis

@@curtisturchin3416 I just got the unit! As soon as I opened the box I could smell it! It’s like bad Chinese rubber products with some kind of chemical, I am not sure how to explain it. Before I start the return process, do you think the smell will go away? It’s not healthy for me to breathe it if it stays like this. Thank you for your response

10 Watt is not much.

10W is not a lot for power, but 10W of optical output is. You can also get an with 20W if you want really fast treatment.,

twice per day for one week, then daily

That will help.

That works if it is a short haired dog. If thick, then the photons will not penetrate the fur.

@@curtisturchin3416 thank you

Research documents that 810 and 660 (or something close to that) are the most effective wavelength for deep penetration and low heat output.

Yes, but it must be combined with self-traction, posture changes, and exercise. Curtis

@@curtisturchin3416 thank you for your response!

1060 produces more heat so it is less penetrating. 850 is better.

The problem with those two wavelengths is they do not have deep penetration. There are studies of these wavelengths and others like blue and they conclude that they are good wavelengths but the advantage over red and infrared is very minimals. So, they do help but they are very ineffective with other types of healing and pain.

Marisa - most of the panels are grow lights marketed as healing lights. The problem is that standing a few inches to a few feet away DRAMATICALLY lowers the penetration. For example 6 inches away is 1/10 the dose of direct contact.

Correct. I mis-spoke

Yes

My pleasure, More coming.

So far, research has not been done on light therapy and flea control. Sorry!

You are welcome!

By stimulating the cat with light therapy, it will improve the uptake of any supplements or drugs you give it. So, use it over the areas that you want to heal with your supplements.

@@curtisturchin3416 thank you. will it be safe for a cat with a tumour?

Where is your pain?

@Curtis Turchin thanks for responding just bought your device on ebay was for a charity sale. The 20 watt unit. Nice device. Had weird shooting pain. In my heel on my left side. I used light on my heel for about a minute and sides. Weird crapping up and just feels wrong. Lasted for about 30 minutes I reused device about 5 times. I'm going to soak feet in apple cider vinegar today. Do you have a book that you wrote can I buy one?

Weird didn't get your response. TH-cam is silly so etimes

@@richardwood8276

@@curtisturchin3416 If it is the bottom of the foot, could be plantar fasciitis. If so, try adding arch supports and putting the paifnul area on an ice pack for 5 minutes before using the light.

The effect is most profound locally. So, if you treat the areas of concern, it should not effect other areas like the face. Hope that helps.

Think of the number of photons that are available to penetrate deeply. Now assume that many of them are absorbed more at the skin level because they are so hot that they heat the skin. Thus, they stay at a superficial level because they create heat superficially and are absorbed by the skin. Hence they cannot penetrate deeply. That is why surgical lasers are often 900-12,00nm because they want heat to thermally cut the skin. Make sense? Dr. T

@@curtisturchin3416 Thank you. Yes, this seems plausible. What about attenuation by other substances such as water, hemoglobin or melanin. Is one wavelength more or less susceptible to that phenomenon, and why?

@@scottsdalemedicalmassage

@@scottsdalemedicalmassage The longer the wavelength the higher the absorption by water. The simple rule is 600-900 nm is best. Within that range, 660 and 810 show the best results in clinical trials on animals and humans.

There are multiple mechanisms involved in PBM, water absorption of infrared photons is often overlooked.

Hi Dr. Claudio, He is doing well. On the “Brain” videos there is a testimonial from him. I will send you the brain protocol. Hope you are doing well!!! Curtis

In terms of deep penetration, 810 is best. In terms of skin, 660 is best. HOWEVER, the majority of 810 nm photons are absorbed by the skin, so 810 is good for skin as well. The problem is that 633, 645, 850 nm diodes are CHEAP and 810 nm diodes are more expensive (810 are REALLY expensive), so manufacturers us the cheap ones and claim they are the best. But, research supports 810 and 660.. Any wavelength works but the higher the power, the more one wants 810 and 660 because they are both COOL and DEEP. At higher power the 850 and above get too hot. That is one reason that low power units use 633 and 850 as they are cheap.

810 and 660 are best but if one, 810. However, any IR or red wavelength is better than nothing
