After viewing MedCram's earlier video about light therapy, I bought a tabletop red light LED unit. It produces Red Light, Near InfraRed Light (NIR) or both simultaneously. I use it for various parts including face, head, feet and shins. Why shins? Because the shins are long bones, close to the surface and NIR can penetrate down to the bone marrow. Studies have shown a stimulation to stem cell growth in the marrow that can travel to the brain which may help reduce the risk of Alzheimers. The unit is a little heavy but I use an ironing board as an adjustable (height) surface that works pretty well. The unit also slants up or down so it's easy to direct the light.

The literature and findings of neuro professor Margaret Naeser in using light therapy for alzheimers, dementia, brain injury and aphasia is mind blowing and so hopeful with better executive function, cognition and speech.

[@mommasoto]

@@MadameCasper Yes most definitely! I hope your friends dad got the help he needed for his speech. Sounds like he has aphasia. Sadly the majority of the time, those who have strokes or brain injuries resulting in communication loss/issues, are often not given the kind of help they need, or told they have aphasia, and have to learn and find out on their own. I know this from our own experience with dad and having worked alongside ARC (Aphasia Recovery Connection early on as I searched for help for dad and eventually became a designer for them). I don't know the extent of his injury, but if it led to aphasia, he should be getting therapy with an aphasia experienced SLP. That's the start. It helps. The brains neuroplasticity is awesome and can heal and make work arounds, but you have to get to it right away and be consistent. Transcranial red light therapy has has also been shown to help tremendously. There are different ways the therapy is administered depending on the type of brain injury thought. Definitely check out Dr. Naesers work and Vielight. Be aware if he has aphasia, which it sounds like, this type of therapy has to be done a very specific way, but it has shown to work. I'd search for a neurologist using red light for brain injuries resulting in communication issues. The light along with a trained SLP experienced in whatever they have be it aphasia, dementia, etc... is a great combo to help those who have lost their ability to speak. All the best!

NIR helps the body create natural melatonin as well. I recently bought a Philip's heat lamp for that reason as well as to promote healing in an badly sprained ankle.

[@aswellyoushould411]

You are getting the benefit of infrared heat and *some* of the light, but not in wavelengths that are shown to heal and create melatonin. The wavelengths that the electron transport chain absorb are 630-600 nm, 810-850 nm, 1060-1080 nm, and there are more but these are the most studied. Don't be too worried about getting it exact, we absorb ranges of wavelengths near these numbers. I have to agree with you though, nothing is more soothing thaninfrared.

Yes! Those seed oils cause inflammation. Also, it seems the study equated high-fat diet to being obese, if I understand correctly (multitasking while listening).

[@rredding]

Absolutely!! Surprising that "fat causes inflammation" as a remark without any additional clarification. Saturated fats are way more inert than mono unsaturated fats like olive oil and those two are way more inert than poly unsaturated fats (PUFAs). The cheap industrial vegetable oils (PUFAs also) are very reactive, becoming oxidized toxins, causing inflammation. Human bodies thrive on animal food, including the saturated animal fats. So, I believe that the high fat chow consisted of industrial oils, otherwise the inflammatory nature cannot be explained. I think this is an omission in the presentation. I know the presenter is with the Seventh Day Adventist church, promoting animal-free diets. Should have been mentioned in disclaimer... 😅😅

The strangest, most beautiful world I'd ever seen. Brilliant, vibrant, ecstatic, stunning . . . I was flying, passing over trees and fields, streams and waterfalls, and here and there, people. There were children, too, laughing and playing. The people sang and danced around in circles, and sometimes I'd see a dog, running and jumping among them, as full of joy as the people were. A beautiful, Incredible dream world . . . Except it wasn't a dream. The word real expresses something abstract, and it's frustratingly ineffective at conveying what I'm trying to describe. Imagine being a kid and going to a movie on a summer day. Maybe the movie was good, and you were entertained as you sat through it. But then the show ended, and you filed out of the theater and back into the deep, vibrant, welcoming warmth of the summer afternoon.

Contrary to the video, you need to be in direct sunlight to get a decent red/NIR exposure. To prove it, lay in the shadow of an umbrella held by a friend, measure your breathing rate for 1 minute (or better yet, your exhale volume rate like I have with a gas mask with the exhale valve leading to a small trash), then repeat the experiment for 1 minute beginning immediately after the umbrella is removed. You can measure a large and immediate increase in breathing that's not due to skin temperature because it happens so fast, and it goes away immediately when you put the umbrella back in place. What's happening is that all the mitochondria up to 1 or 2 cm inch beneath the skin are being kick-started into produce more energy which requires more oxygen. Also, red light may work as well or better than NIR, but people promoting LLLT prefer the more magical-sounding "near-infrared". This is similar to why light therapy research was held back for decades which was because people pushed "lasers" instead of LEDs because it sounded more magical despite not having a different biological response which was known in the 1980's. I haven't worked on hardly in the past 15 years except for my LED helmet video that got a lot of attention, but it's good to see light therapy finally getting the attention it deserves.

It would be fascinating to see how the near infrared therapy worked on mice fed on a FFD (fast food diet) analogue which reproduces metabolic syndrome, inflammation and NASH with a far greater fidelity and effect size than the HF diets commonly used in mouse models. (FFD is still high fat but also adds high fructose.) Still excellent thought provoking work though.

[@GOLEMUK]

Here's a quick extract and link which explains far better than I can. "Although the HF diet produced obesity, insulin resistance, and some steatosis; inflammation was minimal, and there was no increase in fibrosis. The FF diet produced a gene expression signature of increased fibrosis, inflammation, and endoplasmic reticulum stress and lipoapoptosis. A diet based on high cholesterol, high saturated fat, and high fructose recapitulates features of the metabolic syndrome and NASH with progressive fibrosis. This represents a novel small animal model of fibrosing NASH with high fidelity to the human condition."

It'd be nice to see them do an arm with variable fat contents • Low Linoleic • Low PUFA • Low Linoleic and Palmitic Or even more arms... But that'd have complicated their study's focus on near IR. It also might have angered other potential funding sources and been more controversial, but more useful imo.

I had melanoma in 1987 (severe sunburns in FL; English/Irish/Scottish) and have been castigated by doctors since then to stay out of the sun whenever possible and use high level sunscreen 100% of the time. I developed autoimmune diseases, migraines, multiple BCC and breast cancer. At least I didn’t get C19. I’m heading back outside!

If you had melanoma, a red light panel is safer, with no risk of skin damage

Stunning! Something I've always suspected but never looked into nor ever had any solid evidence. Thanks for this video Dr. S.

[@janissquirell5072]

Am I the only person, who is wondering that high fat diet induced likewise IL1b, TNFa, which both are proinflammatory as well as IL10, which is antiinflammatory? And the NIR light is suppressing them all likewise? Then maybe it is not antiinflammatory property, but sooner just generally suppressing influence on expression/production of all chemokines?

[@c_b5060]

The results would likely be more pronounced if all groups were feed identical amounts of Linoleic Acid (omega-6). (Instead of omega-6, the high fat groups could have higher fat using omega-3, omega-9, and saturated fat.)

Why do you think this?

@@c_b5060 Very interesting, thank you. Oddly enough, at the recommendation of an ophthalmologist, i've been supplementing with flax seed oil in an attempt to treat dry eye (a significant source of linoleic acid). It seems to work a bit (along with hi MW hyalauronic acid), but obviously this would collide with the advice you're passing along here. I will definitely look into this.

One key factor in all lab studies on light would be the type of lighting in the lab itself. Are they using bright fluorescent or LED lights? A great study would be to have a wing that live in only incandescent lighting to compare against mice living in LED or Fluorescent. I’d love to see the numbers on cortisol and melatonin regardless of diet.

If someone watches this without knowledge of healthy versus pro inflammatory fats they may make the false assumption that any high fat diet is bad… The HFD is extremely high in pro inflammatory polyunsaturated and omega oils (though not omega 3). You also don’t differentiate between grass fed/finished saturated fats and grain finished fats, the first being non inflammatory and the second very pro inflammatory. I do applaud the research on NIR.

[@AlexProudfoot1]

When you state high fat, what type of high fat? Fat with more omega 6 tends to be inflammatory, whereas more omega 3 is perhaps anti-inflammatory.

[@OpentoEvidence]

I agree. The use of "high fat" suggests that eating fat is bad. If the mice were fed high fat Omega 3s would there be even more anti-inflammatory results?

When I was a kid here in California...I got a ton of sun because we never stayed inside when I was a kid. I credit my love of the sun to lack of any serious health issues.

LED lights give off much less near infrared than the old incandescent lights. Wonder will this have an effect on people over the long term.

[@rushmoreidsystems7323]

I have a friend whose spouse has dementia that developed rapidly so this topic was interesting... We always have to be careful about conclusions, because, "Correlation is not causation." It will be true that well people are more likely to go outside while sick people will be inside more. In this aspect, in fact, cause and effect are reversed: Being inside is caused by illness, and being outside is allowed by being well. So, in the case of the survey of people's time outside, correlation has been established, but NOT causation. One could just as easily use, "correlation equals causation," to say that the survey shows that, "illness causes people to get less light," rather than, "less light causes illness." Once correlation is found, THEN a different study can be designed to tease out whether there is causation rather than just correlation.

Why does the nutrient composition in the Regular chow show about 70% while the nutrient composition of the High fat diet shows 100%. Fiber?

[@HappyCetacean]

The two sets of data in the table at 2:08 are calculated on different bases and should not be compared as you do in the video. Notice how the high fat diet macronutrients on the right adds up to 100 (20 + 60 + 20 = 100%), and the top left doesn't (19.1 + 5.8 + 44.3 = 69.2). The top left is actually reporting in g/100g of sample, while the top right presented protein/fat/carbs in the way they present in the ratio of calories in the diet. The "kcal" unit in the top 3 left column fields shouldn't be there. The comparable high fat macros can be back calculated using the final 5.21 kcal/g result to 14.9% protein, 44.7% fat, and 14.9% carbs since we know 4 Calories/g for protein and carbs and 9 Calories/g for fat. (14.9 * 4 + 14.9 * 4 + 44.7 * 9) / 100g = ~5.21 kcal/g. Total moisture content would be 30.8 g/100g for the regular chow and 25.6 g/100g for the high fat diet if you were curious--it's the non-calorie contributing portion. The fatty acid profiles are also way off. The left side is again in g/100g of sample, as total saturates + total monos + total polys = 5%, a normal amount of fatty acids when compared to the crude fat result of 5.8%. The right side again nicely adds up to 100% (32.2 + 35.9 + 31.9 = 100), so we know that's a normalized profile (all fatty acids add up to 100%). Using the 44.7% fat from earlier we can adjust total saturates to 14.4 g/100g, monos to 16.0 g/100g, and polys to 14.2 g/100g. Source: I work with food science and nutritional labeling for a living and these are common issues when comparing data from different sources.

[@Medcram]

Thank you for catching it and explaining it!!

[@wocket42]

Top left is as you say, % of total weight of the chow. Fibre and ash complete it to 100%. You can easily find the PDFs for the chows and where they got their data from and where they went wrong with copy n paste. Top left "normal" macros would be Calories from Protein % 25, Calories from Fat % 17, Calories from Carbohydrate % 58 as per PDF. But: Fatty acid profile for fat chow is in gram per 245g mix as per other PDF. Who reviews these articles?

I'm all in favor of people getting sunlight. I'm definitely in that camp I think it's evolutionarily and biochemically a sound practice. I'm very suspicious about these Mouse models though. I think that there are ease of use has made people create abnormal physiologies that don't in any significant way corresponds to human beings and normal life. Even though I find the conclusions plausible I would not take this research very seriously until it's replicated in a more normal system, preferably human. Also neuroinflammation happens in many diseases and should not be equivocated with senile dementia. There is a lot of other important stuff going on that makes it so devastating.
