I asked the study author to compare their intervention to sunlight. He stated that the device gives about 17mw/cm2 at 50cm and the sun is about 3mW/cm2 in the wavelength range so 5.5x more intense at that wavelength approximately. However, he also stated that he's seen the same switch at 2 min (just as good as 20 minutes). It seems to be like a switch that goes off with enough exposure and there is no dose-response curve meaning that more time or intensity doesn't mean a bigger drop in glucose. I've asked him for commercial product recommendations and I'll see what he says. For more information and continuing medical education on vital topics, such as EKG, and congestive heart failure to name a few go to medcram.com today.
Great enlightening video! Love this series on the light/health connections! Makes biological sense that daytime active creatures spin up metabolism/energy availability when they are most likely to be active food gathering, and conserve more energy with lower metabolism at night during rest✨ My arthritic grandma used to take sun baths during the 1970’s for 20 minutes daily which she felt eased her pain inflammation! Is there a healthier source of light for this red 670 nm light? I have heard that perhaps some led light may not be good for our eyes? Anything special about using one’s back for the light exposure vs other parts of one’s body? Are the red led caps and such good, or is sun light preferred for multiple benefits? Thank You again Dr !
As a species we used to sit around a fire every night, getting a heavy dose of near-IR & red light. Crazy how much our lives have changed in just the last 100 years.
I was diagnosed with Parkinson’s Disease. I bought a red light device and have noticed the improvement of my symptoms when o have used it consistently.
Its all copium It will do nothing for Parkison’s. It might do something if you could fire the light directly at your brain but thats impossible. My condolences man. Diseases of the Brain are brutal. Honestly human life is brutal.
I have been a historically poor sleeper my whole life. Watching your videos on light have transformed my sleeping. I rarely have difficulty sleeping now. Many thanks

This is so intriguing to me. In 1995 I moved from Kansas to the Virgin Islands for a job. I weighed 165 lbs. I was there for 18 months. I didn't have access to a scale, but I knew I was losing weight, because I had to buy new clothes. When I got home, I was astonished to find out I weighed 122 lbs. I hadn't actively cut calories. I wasn't hungry. I actually exercised far less, and my diet was worse in the VI. When I came back home, I immediately started gaining weight again even though I was trying not to. Very quickly I was back to my original weight (and now I'm much more than that!) I've spent years puzzling over this. The only other changes I can think of are more sunlight and saltier air.
@@EVanDoren It could be. I don't think so, though. They have supermarkets there, and I was pretty much eating the same diet I ate at home. Idk. If I could figure it out, I'd try to do it again.
Thanks for sharing your interesting experience. I wonder if you ate less processed food and sugary drinks while in VI. Those food are more accessible in the mainland like Kansas. I too used to live in the Caribbean and had lost weight. I ate more "real food" (not processed food) over there than back in t he mainland.
I think the Virgin Islands are closer to equater and intensity of sun is greater. I noticed that when I would go to Africa I would lose weight. On returning to US I would gain the weight back.😮
Before the pandemic, I had figured out that I had dysautonomia/POTS and that sunlight/light hygeine helped dramatically. Watching so many new people struggle from dysautonomia/POTS and other complications of the spike protien, on top of my own aggravations from it, has been sort of traumatizing. I wanted awareness, but not via millions of new sufferers. I wanted enlightenment, not enfrightenment. Your light series has been the best medicine for that frustration and remains my favorite pandemic silver lining. Thanks, y'all!
Hey Elizabeth, could you talk a bit more about the differences you have noticed with light in regards to pots/dysautonomia? as in symptoms reduced/gone? Seems to be my story too... Thank you!
@@Arugula100 I got mine from Aliexpress. It was AU$30. It has 60 patches with each patch having 1x 660nm red light & 2x 850nm lights. It uses a type c USB cable (which came with it).
Great information. Started watching you during Covid and without any training past High School Science have learned a lot about cellular biology. I was looking at the diagram with all the letters and thought, "I can't believe I am following all of this!" But the point about how badly we are affected by separating ourselves from nature and light is so important. I have made the effort to get out more. Luckily, I am retired and live in north Florida, so no excuses here. You are really on to something. But since nobody will make money, it may be really hard to get the message out.
I watch about 6 functional medicine MDs and DCs here on u tube and Dr. Roger is by far my favorite. We are creatures of the light for sure. Thanks for another great talk! I let my real estate license expire and work my old tukus off as a gardener now and never been happier or healthier. Not getting rich.... getting healthy and happy cause health is wealth. Will tell my Kaiser D.O. about you. Someday I will meet her as its been 20 years since last blood work and maybe im due again.
Thanks so much !! Just purchased a panel and after I showed this to my wife , she didn't give me any flak!She trusts your opinion much more than the ER doc she is married too. Could you please do an analysis of the Nature study regarding long COVID and lab findings? Thanks so much for all you do - it's so helpful top so many!
The moral of so many of these "stories" (research papers) is - Try to imagine how humans lived for the last few thousands years, and follow about 90% of it. Be outside. Occasional meat only, occasional sugar and oil. Live kind of like a pauper. Live slower. More social interaction everywhere - the street, the train, office, homes. Cook basically all your meals. Don't over sanitise and clean everything. Walk everywhere. Buy less and work less. Etc
@@petersteenkamp Surprisingly that adage is only supported by evidence in some specific cases. There appears in bronze and iron age literature from the "near east" references to 3 scores and ten being a good life etc. Beyond literature there is no shortage of evidence from middens of teeth and bones of people with advanced age. It was and has not actually been rare for homo sapiens to live seventy or so years, in the same way that many other species live long lives. The industrial revolution has played some role in a deterioration of life expectancy, tied to horrible urban conditions etc. But this does not speak to many thousands of years of humans living more balanced lives in rural contexs.
Thank you ! From the practical point of view, it would be very useful to get some recommendations for in-home therapy devices. Not specific brands (I understand you can't do that), but categorized by design details such as: panels vs. suspended light-bulb, wavelength, power...I searched for this information, but couldn't find an independent and serious review.
Hi, Dr. I am a type 2 diabetic, and I noticed that the two times I participated in a week-long campout, my blood sugars were much better. Spending a week in the outdoors exposes one to a lot more red and NIR light. Now, I know that there is another large confounder: During outdoor campout I am more active, averaging over 20,000 steps per day on my pedometer, compared to around 7,000 steps per day in my usual day-to-day life. However, I think you may be onto something. I had previously bought a red/NIR lamp for my knees that used to hurt from time to time. I may try using it at other times to see if I notice any blood sugar reducing effects.
A component that most overlook is the impact on your circadian rhythms. I have a plant degree and those rhythms have been well studied and there is some research in mammals/humans showing it's importance, including in glucose metabolism. Your camping trip would have done wonders for getting that rhythm back in shape (as well as the increase activity that you observed). If you were to use this red light for any sort of treatment, I suggest doing it at the same time everyday and in the evening just before sleep. This is when the plant researchers found it benefits plants and it simulated sunset.
The single best thing you can do for T2 diabetes can be summed up in three words: Don't. Eat. Carbs. It really is that freaking simple. The diabetes-industrial complex knows that a patient cured is a customer lost.
maybe I can help as a fellow "sweet friend"....to remove the confounding variable as I had to CUT DOWN on my exercise and activity due to too much. And the red light (even more than that, IV Ozone and HBOT...largely dropped insulin requirements by 2-4 sliding scale parameters!
I have bought it some time ago and the one thing that I have noticed is that my migraines (that I was getting regularly) are no longer coming back. I might have incidentally a little bit of a headache but nothing that lasts longer than an hour or two. Before I had headaches of many hours of days (with each month one bout of a migraine of 3 days). I hae also noticed that my levels of energy are slightly higher. Three interesting facts: when my family member was sick with flu with a lot of coughing I set it up for her - and after half an hour she stopped coughing constantly (to only once every couple of minutes a slight cough). So it dit something to her lungs that the production of phlegm was was much slower. Second thing, actually a warning too, I have heavy menstrual bleeding and I am usually in a lot of pain. I thought I could use this light on my lower abdomen. But the pain was not better because of this - and my period lasted longer and I got even a lot of pain afterwards (a couple of days). So I cannot recommend if for that purposes. Third of all, I had allergies and inflammation in my body my whole life and it is normal for my to have enlaged lymphatic knots (mainly under my jaw). After using this light it completely went away which was shocking to my. For the first time in my life I could really squeeze my neck without wincing,
I have just ordered a red lamp as I live in the UK. When it gets to December we are lucky to get 6 hours of sunlight and invariably many winter days are cloudy or raining. I have got my Hba1c down to 5.5 (at my worst it was 12). That dropped from 5.9 in the three months from May to September whereby I was out walking in the sun. After hearing this I think having a red lamp will only be beneficial even though I will continue to walk but of course I am more covered due to the temperature dropping. Thank you for explaining this clearly. I had heard of the benefits of red light but didn't know why now I know.
Field report: several months ago I tried switching from blackout sleeping to an LED light strip set to the dimmest red - expecting a worse sleep - and I'm actually much more rested. Mostly just my face and arms are exposed and wattage is low but duration is high. It looks just like a photographic safelite so I'm guessing around 635nm wavelength.
I've retired to southern AZ. No shortage of sun here. I do feel better when I have a chance to get outside and I have not only lost weight, but my blood sugar level is lower. This all makes total sense to me. The internet is a wonderful source of information. Thank you for posting this.
It also stimulates hair growth and hair will grow faster, for example, after chemo. It also helps with relaxation. Personally, it helped me tremendously during my cancer treatment. All my hair grew back normal.
You are doing a true service in letting people understand how important light is. Well done. Also FINALLY someone that doesn’t demonise UVA and UVB light! Finally!
@@classicgameplay10 watch their video on “light as medicine”. Long and short is UV-B needed for vitamin D3, UV-A for nitric oxide and vasodilation but you should still watch the video.
Yet another informative & pertinent video about sunlight and health Doc! Thanks for these important videos! I am sending this one over to my cousin (M.D.) for viewing! Hope that all is well with you & your family!
That is a new addition to my knowledge about red and near red light lamps. If you live in Northen Europe, going out in sunlight from mid October is a dream which never comes true. Redlight and nearread lamps make sense to have
All red lights on my next Christmas tree! This is an amazing discovery. I do try to get out more often to get as much natural D3 as I can, and supplement for it as well (maintain ~ 70 ng/mL D 25-hydroxy). Now I'm off to order some red lights. Thank you for your explanation and posting this.
This mechanism should also improve fatty acid metabolism, right? Not just sugar metabolism? If it's the electron transport chain that's being helped, that should mean both glycolysis and beta oxidation should benefit, correct?
I greatly appreciate MedCram videos, especially on red light therapy. One correction: in the Cellular Respiration diagram the word “glycolysis” is misspelled. (Sorry, It’s the English teacher in me.) I have type 1 diabetes and own a Red Man model red light. I’m going to get back into the habit of using it again based on the results of this study. Thank you.
@@Medcram There may be no more common demonstration of confirmation bias: we read what we have just written and it looks good until we send it on its way.
Great info. You should upload just the last few minutes of the video like every day, so that information will (hopefully) reach more people. Also consider making more shorts of your words of wisdom. Great channel!
Yes! Excellent. Answers some questions RE: NIR exposures that have been swirling around, and poses more. This summer I have been very intent on increasing outside activity, to get NIR increased. I had been very curious about just HOW NIR to the brain induced melatonin within mitochondria, this information helped scratch that persistent itch! Now, I intend to increase nightly campfire viewing as much as I can, in hopes that NIR and visible red light can better access cells even after sundown. This should help curb my common screen viewing habits before bed. I am coming to more fully see that we have been so very dependent through countless millennia of adaptation outside, and around campfire evenings, that we must be harming many acquired beneficial effects. Diet and other lifestyle modifications more in line with prehistoric living conditions need far more clarification to benefit our paths forward IMHO. Thank you for this important clarification!
I'm a plant scientist and we use far red light to impact the circadian rhythm in plants. Nearly all, if not all, plants and animals have a circadian rhythm and I believe this far red light exposure in this experiment was triggering that cycle. The theory is that the setting sun gives that burst of extra red light. Since you have trouble with sleep, might I suggest if you wanted to use this treatment on yourself, use it in the evening to help maintain your natural circadian rhythm.
Leave it to Roger Seheult to bring us yet another of the most surprising and fascinating research findings. I can't even imagine the quality of medicine if all doctors kept themselves this well informed and dug this deep.👏
I'm still speculating that the improved metabolism is due to light energy being used to produce melatonin in the skin. Melatonin has been shown to increase atp production because of reduced ros generation. The water viscocity claim is based on one cited paper and is only a hypohesis. Viscosity may reduce with light, but it was not shown that is what increases atp.
Since I saw your videos on light I have been spending more time outdoors. I sit out side and work on my laptop and work in the garden more, I really have enjoyed this change. "Get outside!" Great message, Thanks!
I would like to. But when we do that, we run the risk of appearing that we are endorsing products. I don’t have one and I don’t know if I would buy one. But I am trying to get outside more.
Very promising research! And many redlight devices available for consumer purchase have both red light and NIR. I am definitely using mine front and back head and torso every day now that days are getting shorter and I am outside less frequently.
what device did you purchase? I'm about to buy one from reddotlight (what bryan johnson uses, seems legit good) but it's like 250 for device+delivery from china and seems big enough for just the face or perhaps face and upper torso
thanks! great review of new research…I listened while basking under my red lamp -which I purchased after your lecture @ the benefits of light therapy -so enjoyable😃
As someone with a scientific education i really appreciate the break down of the graph. Prior to the explanation i could have easily assumed what you warned against at the end of this video.
I ate pavlova last night for dessert. I should have used my near infrared lights and infrared light. I needed this video last night. Thank you for these excellent videos.
I have ME/CFS & Long Covid. Used a high quality red light consistently for months in a row. I never did know if it was doing anything. Didn't seem to help my wrecked metabolic functioning. I guess if the studies are saying it helps, I should keep at it.
It seems that most of us have been deprived of long-duration, low-intensity red/IR light exposure over the past few years as we've transitioned from broad-spectrum incandescent light bulbs to LED bulbs (most of which emit very little energy above 700 nm). Although it's interesting to consider high-intensity, short-duration therapy and its potential effects, perhaps we should prioritize study of any effects that might have resulted from the change in indoor light exposure many/most humans have already experienced. Perhaps incandescent bulb use should not be eliminated but should be limited to cold/dark seasons when the heat they generate is not wasted (and their light compensates for lower sunlight exposure during those seasons).
Incandescent light bulbs should have never been determined by the government to be removed from society because the light emitted is healthy compared to the horrible, artificial white light LED emits. Similar to their food pyramid which is also poor advice.
Reinforced by your data on mid IR .. I run in Texas at 8am for 90 minutes shirt off and 40 minutes at 5pm. 130 minutes of MIR, I also run in a,park by a lake so plenty of green to reflect the IR. I was on my morning run when I listened to your podcast. I run when uv Index < 5, with 5000iu of vit d .. my levels are good but I would have expected “optimal” .. thank you .. made me feel validated this morning.
I have a near infra-red light that I use on my testicles for testosterone. (10 minutes per day 5x a week) I’m 72. It brought up my testosterone from 300 to 1000 and free testosterone from 30 to 102 in 3 months. I have not used it for my insulin resistance. I’ll try it using it with my CGM and see if it helps. I was walking on the beach for an hour a day in Florida but didn’t see a noticeable difference. I did just try it and my reading went from 146 t0 130, but I would need to do it a number of times to confirm it as not being a coincidence.
Thanks for this dude. I knew about it and I have been doing it from time to time also, but I was not sure about it so I was slacking of and I do not go and do testing regularly, so did not have any good confirmation that it actually worked. But now I for sure am going to be doing this for ever.
@@bengurion5285 Yeah, this dude should give more information. I checked after reading this and this thing is controversial. I can not find anyone who can prove this works in humans. But a lot of people who say they have tried and done blood work and got no more test. So please, If he can prove this a lot of people would benefit to know more. One thing i noticed while checking up on what others have tried is most seem to way over do it. As in pretty much cooking there balls. It seems that just enough is key. Maybe he has stumbled on the right dose. As he said only 10 min 5 x week. I am going to try it anyway. When I used to try this I did get benefits, but I think I did to much and lost them. But while it worked I did notice a massive increased libido though, to an annoying degree it think that is why I was slacking of in doing it or I just over cooking them. I wish it was possible to get topped out test levels, to get the recovery and mental drive and confidence but without also way higher libido. Because I just do not want to be thinking so much about things like that, I have things to do and at a point that type of distraction is just to much.
Sir, I just wanted to ask you, if Melatonin mitigates ROS, has annyone ever tried infusion of melatonin, to say help with pneumonia and stuff? Shouldn't that work theoretically?
Wow! Another great video guys! Yet another reason that living near Canadian/US border I feel fantastic in the summer and crappy in the dead of winter. Had tried SAD lamp which helps with waking up in the morning, but I'm hopeful that getting a RED/IR therapy device could help a lot in the winter!
@@calluna5030 Interesting! I have recently incorporated grounding in my day to day life as well, I think it's had some noticeable effect on a tendonitis issue I have. And also, structured water
This raises several interesting questions 1) How much red light is in typical incandescent bulbs/fluorescent bulbs/sun? White light also contains red light, so it would be interesting to see if there is any benefit to cranking up light in general (RIP electricity bill). 2) This study doesn't consider other frequencies. Do they have minimal effect? Negative effect? Something else? 3) Last I recall, red light doesn't penetrate as far as IR, so is the effect mostly skin deep? There's a measurable CO2 increase, so it's presumably non trivial at least.
If you can get incandescent bulbs.. which you can online or if you have a stash. I don't know the amount, but there is some.. I don't know if there is enough for this kind of effect ; although I do know some folks who do feel better just using them for bright lighting during daylight hours. Flourescent lights more blue, less/little red and have awful flicker - which is a whole 'nother beast..
Awesome information, and the sort of thing that not only passes aling valuable information, but also shows us non medical folks that there are dedicated / smart people woeking on very useful, non-drug therapies snd the general understanding of the complex systems of the human body and health..
Do we need to be concerned about OTC devices that state a certain wavelength but don't get calibrated? Or are the damaging wavelengths far enough away that it is not a concern for our skin?
This is the first video on this topic I've seen that is evidence based and quotes light intensity. Well done! The big question has to be: What's the difference between one of those expensive red light devices and a 20-minute midday stroll? Sunlight will provide 1-5mW/cm2 compared to 0.1-50 mW/cm2 for one of those light boxes (depending on the box).
Great video. The part I don't get is the proposed mechanism "reduction in viscosity of water". Given that this cannot be meaningful due to temperature alone. The reduction in viscosity must be thru alteration of the intra-mitochondrial fluid composition. Can you elaborate?
Yes this was my first thought too. What is the MECHANISM? How does 670 nm radiation reduce viscosity of water? Has this been tested extra-cellularly? My general principal is 'No mechanism, no effect.".
I can’t. I was just as surprised as you are to discover that that’s what they think the mechanism is. One area topic that I am interested in. Is this idea of structured water that I’ve heard about, but have not investigated.
Would a person of darker complexion or more pigmentation require more light or a different frequency to get the same results? How does one go about determining the proper duration, frequency and intensity of red light that is required? Are there other studies out there that might address some of these questions? How do you determine if you’re over exposing yourself to red light therapy? Great video thanks for a clear explanation regarding the work within the mitochondria.
Jack Kruse has been trying to get people to pay attention to light rather than just food for a long while. The effect of blue light on serum lipoprotein profile is already established, too. Thank you for the lecture and acknowledging the role of electromagnetic waves in biology. By the way just a small correction: the term, glycolysis, is spelled with the letter Y used in two separate locations.
@@Medcram Well thank you again for sharing all that you share, trivial corrections such as that are definitely a secondary priority. First things first - your commitment to spreading curiosity about physiology is contagious, let me send back your way the following, which you may have already come across. Andrei Sommer: cytochrome C oxidase bound water is an infrared target.
Dr. Sheult is a wealth of knowledge. He is disseminating that knowledge for the benefit of humanity. Please listen for your health. And, share for the health of others. ❤️💡❤️
Thank you to you both for all that you do - this channel is phenomenal, truly one of the best. A question I’ve had for awhile now - you’ve mentioned that infrared light (and I guess red light?) can penetrate clothing and sunscreen - do you know what kind of clothing, how many layers? The past few winters I’ve made it a priority to get outside every day, even in frigid temps - but would love to know if the type or amount of clothing I’m wearing is blocking these healing rays and if I should be trying to expose more skin!
@@Medcram wow, thank you so much!! Y’all are doing important work and it means so much to me (in myriad ways). Will be buying more courses and continuing to share/promote your work. I am so grateful. Hope you both have a great weekend
Red light ( 650 to 800nm ) stimulate mitochondrial respiration. 670 I'm and other longer wavelengths of red/ infrared light -increases ATP production in which requires more fuel, since glucose is the primary fuel, thus red light reduces sysrptemic glucose concentration. This can help in diabetic management and weight loss.
I started watching long ago for CE. Then I retired and moved to Thailand. When covid struck, I started watching routinely again. Again, thank for the putstanding videos ❤
I wonder how enduring this effect is? Iow, would a treatment once a week offer any practical benefits or would treatment every day or every hour be required?
Nowadays, red NIR lamps are popular for health improvement, isn't a better option for example a halogen bulb in an office desk lamp with corresponding power? The spectrum of these bulbs is much wider and mainly closer to the sun... and the price is a bargain
Thanks for the reminder. As we're coming into fall now, I need to start using my red light lamps in the morning before work. I'd put them away during summer.
I would use the red light at night or later in the afternoon. Natural sunlight is in the blue spectrum in the mornings which is designed to stimulate function and be alert. Whereas the red orange spectrum is what the setting sun emits signaling the body to produce melatonin and fall asleep. Thus natural morning blue light and evening red maintains our healthy circadian rhythm. We are now viewing our blue light emitting devices at night creating unnatural exposure. Wearing blue light filter glasses and using incandescant bulbs at night is healthier.
Dr. Seheult, thanks for this report. I have been experimenting with a radiant heater, which normally produces orange light (590 - 620nm). Orange is a shorter wavelength and a more energetic light than red light (620 - 750nm). When I reduce the power to the filament of the radiant heater, it becomes dim however, never turns red. This I don't understand. One question is, if skin was illuminated in the red as was done in the study you discussed, and that skin had a cancer on it, would the red light help or harm the cancer lesion ? Secondly, would a higher frequency of light (orange) be more lightly to affect cancer metabolism differently than healthy-cell metabolism ?
I suspect that red and infrared frequencies of light are healthy. In the infrared frequencies I suspect energy utilitization is augmented when the cytochromes in the electron transport chain absorb the photons and move to a more exited stated that speed electron transport in a process similar to plant photosystem 1
Does a wide area of the body need to be exposed to red light therapy or nir light therapy to get the systemic benefits? Or can it be used only on a specific part of the body for targeted pain relief and still benefit the whole body?
I would highly recommend checking out Alex Fergus's Red Light Therapy channel. Very in depth reviews of almost all R/NIR light therapy products on the market. For the type of effect discussed in this video, look for a body panel.
Thanks for the great content. It seems to me that there’s no reason that we shouldn’t be able to get all these benefits from just sitting in front of the heater lamp that they use for reptiles. One of those lightbulbs is like 20 bucks. That should expose you to the full spectrum of infrared, near infrared, and red light. is there some reason or advantage to using LED specialty lamps with two or three fixed wavelengths? If it’s just basically thermal absorption for the water in the mitochondria (why doesn’t affect the rest of the water in the body? Or does it? It must) then, to a certain extent the wave length shouldn’t be that important.
Sunlight is great, no doubt; and you've made that case elsewhere. But, regarding indoor lighting or lamps: white light includes all colors, including red light. So at the right intensity, area, time, and distance from the body, couldn't ordinary, white light give the same benefit? (Granted, of course, that one or more of those factors will need adjusted versus a red-light lamp, since the red frequencies are but a subpart of white light.)
Wonderful explanation which provided wonderful data from a randomized double-blind control study. The fine art of a good methods section in any research study. :-)
Should we use red therapy? At my local tanning salon, they charge to use the red lights. Im not sure how significant the test results were that you mentioned..
The red light only covers one square ft of your back, would there be a more pronounced effect covering more of the body? Second, how long does the increased BMR last for?

Thank you for delving into this study and explaining the effects of red light on the mitochondrial mechanism. Have or will you produce a video on the synergistic effects of red light with Methylene Blue? Apparently it's quite profound.
Those GTT blood glucose levels seem to be fairly low. It looks like none of the people studied were diabetics. It would be interesting to see the same study with diabetics both on medication and those who manage their glucose by diet only.
@@Medcram There's a vast difference between healthy individuals with elevated glucose and diabetics, but media and marketing are proposing that red lights *cure* diabetes. There's a long distance between treating wrinkles and skin conditions with infrared-range light, including diabetic lesions, to propose red lights as a treatment for diabetes itself, which is what the comments to the video make it look like - and Google results leading to wellness websites, making red lights good for *everything.* Bone growth, hair repair, acne, oral care, psoriasis. Only skin issues treatments have scientific backup. Infrared light can penetrate the body several centimetres deep, but red light, just 1 to 3 millimeters. So, no peer-reviewed papers supporting this claim, but one study uploaded to a pre-print service and to a social network. And the cohort study, is not about red light, but *outdoor temperature and bright sunlight,* which included triglycerides - and physical activity? Were the subjects just lying taking sun baths? In England and the Netherlands? In a country where people die due to insulin being outrageously expensive, proposing red lights as a treatment is borderline irresponsible. The last analogy was flawed, to say the least. Chilean here. The comparison between life in developed and developing countries disregards all the other differences: diet, climate, social activities - the existence of public/affordable healthcare systems. Guess what: there are plenty of diabetics in Chile, and, interestingly, in American First Nations, who are about three times more likely to get diabetes than the white population. Attributing Americans' obesity and diabetes rates to lack of outdoors activity and sunlight, in a country where even bread is actually cake, is fallacious. Are we already into quackery territory, or can we still stop before having to report the next videos for misinformation? Librarian here. Please, prove me wrong with peer-reviewed sources.
I've been researching this, and one thing I'll say is the power density manufacturers list aren't always what independent labs find. I would look for some independent testing of output, but suffice it to say that many of these devices probably are helping, even as they may not be at the power density levels that they claim, and we should keep it In nind because the peer reviewed papers probably are more accurate in the stated power density levels used..
Thanks a lot, Dr. Roger for this excellent podcast. This opens the topic of sunlight and its healthy effects on human body. Red and infrared light are beneficial to the human body. I have been using a red light of 660 nm LED Photobiomodulation therapy for wound healing since 1996 and I have a rich experience of almost 90% success. Amongst these I would like to stress upon the good results I achieved in diabetic patients. I have always selected patients for this therapy. I would like to have an opinion from you Dr. Roger on the following experience of mine : I have seen that wound healing improved even in those patients who did not keep their blood sugars controlled. Would it be that the red light exposure helped reduce local blood sugars in the open wounds much more than the actual blood sugar level in mmols/dl? Dr. Roger, can you please explain? Dr. Bipin Deshpande, Dermatologist, INDIA.
That’s interesting. I’m not sure. It seems also that it might give more local energy in the form of ATP for wound healing but I know that they are using it here as well.
You do an amazing job explaining concepts very clearly and with diagrams. Those help one understand and visualize what you are teaching. I like how you reference to your other videos like the Covid-19 and light, Light as Medicine and how it ties to this particular video. Well done. I learn so much from you Doctor.
Northern latitudes here. I get out a lot! Work out five days a week, plus bought my own red light/Nir unit and use it. Plus go to one of our gums locations where they have full red light treatment rooms. I am hoping it might help healing? I use a NIT bulb for my restless legs and it really helps.
I asked the study author to compare their intervention to sunlight. He stated that the device gives about 17mw/cm2 at 50cm and the sun is about 3mW/cm2 in the wavelength range so 5.5x more intense at that wavelength approximately. However, he also stated that he's seen the same switch at 2 min (just as good as 20 minutes). It seems to be like a switch that goes off with enough exposure and there is no dose-response curve meaning that more time or intensity doesn't mean a bigger drop in glucose. I've asked him for commercial product recommendations and I'll see what he says. For more information and continuing medical education on vital topics, such as EKG, and congestive heart failure to name a few go to medcram.com today.
The explanation invoking the water viscosity is not convincing. Just 2 min of light will have zero effect on the cells temperature inside the body.
Great enlightening video!
Love this series on the light/health connections!
Makes biological sense that daytime active creatures spin up metabolism/energy availability when they are most likely to be active food gathering, and conserve more energy with lower metabolism at night during rest✨
My arthritic grandma used to take sun baths during the 1970’s for 20 minutes daily which she felt eased her pain inflammation!
Is there a healthier source of light for this red 670 nm light?
I have heard that perhaps some led light may not be good for our eyes?
Anything special about using one’s back for the light exposure vs other parts of one’s body?
Are the red led caps and such good, or is sun light preferred for multiple benefits?
Thank You again Dr !
@@michaelh8167 Water reacts to light itself, it doesn't need to be about temperature
When I go to stand in the sun in the later morning, I can feel in just 5-10 minutes that my appetite increases. It really feels like a switch.
If it works, as some say, the way of NO, then, it depends on nitrite level. After all nitrite is converted to NO by CcO, no more light is needed.
As a species we used to sit around a fire every night, getting a heavy dose of near-IR & red light. Crazy how much our lives have changed in just the last 100 years.

I was diagnosed with Parkinson’s Disease. I bought a red light device and have noticed the improvement of my symptoms when o have used it consistently.

It might do something if you could fire the light directly at your brain but thats impossible.

Thank you very much!
This is so intriguing to me. In 1995 I moved from Kansas to the Virgin Islands for a job. I weighed 165 lbs. I was there for 18 months. I didn't have access to a scale, but I knew I was losing weight, because I had to buy new clothes.
When I got home, I was astonished to find out I weighed 122 lbs. I hadn't actively cut calories. I wasn't hungry. I actually exercised far less, and my diet was worse in the VI.
When I came back home, I immediately started gaining weight again even though I was trying not to. Very quickly I was back to my original weight (and now I'm much more than that!)
I've spent years puzzling over this. The only other changes I can think of are more sunlight and saltier air.
wow. how interesting!
I think your diet on the Virgin Islands was vastly better.
@@EVanDoren It could be. I don't think so, though. They have supermarkets there, and I was pretty much eating the same diet I ate at home. Idk. If I could figure it out, I'd try to do it again.
Thanks for sharing your interesting experience. I wonder if you ate less processed food and sugary drinks while in VI. Those food are more accessible in the mainland like Kansas. I too used to live in the Caribbean and had lost weight. I ate more "real food" (not processed food) over there than back in t he mainland.
I think the Virgin Islands are closer to equater and intensity of sun is greater. I noticed that when I would go to Africa I would lose weight. On returning to US I would gain the weight back.😮
Many old doctors and grandmothers used to recommend sunlight and fresh air for sickly people, so maybe they were right!
And babies!

Before the pandemic, I had figured out that I had dysautonomia/POTS and that sunlight/light hygeine helped dramatically. Watching so many new people struggle from dysautonomia/POTS and other complications of the spike protien, on top of my own aggravations from it, has been sort of traumatizing. I wanted awareness, but not via millions of new sufferers. I wanted enlightenment, not enfrightenment. Your light series has been the best medicine for that frustration and remains my favorite pandemic silver lining. Thanks, y'all!
Hey Elizabeth, could you talk a bit more about the differences you have noticed with light in regards to pots/dysautonomia? as in symptoms reduced/gone? Seems to be my story too... Thank you!
Ditto. Well said!

Great information. Started watching you during Covid and without any training past High School Science have learned a lot about cellular biology. I was looking at the diagram with all the letters and thought, "I can't believe I am following all of this!" But the point about how badly we are affected by separating ourselves from nature and light is so important. I have made the effort to get out more. Luckily, I am retired and live in north Florida, so no excuses here. You are really on to something. But since nobody will make money, it may be really hard to get the message out.
Money could be made on light therapy
Start cranking up red light contraption.
I watch about 6 functional medicine MDs and DCs here on u tube and Dr. Roger is by far my favorite. We are creatures of the light
for sure. Thanks for another great talk! I let my real estate license expire and work my old tukus off as a gardener now and never been happier or healthier. Not getting rich....
getting healthy and happy cause health is wealth. Will tell my Kaiser D.O. about you. Someday I will meet her as its been 20 years since last blood work and maybe im due again.
What a great story!!
Thanks so much !! Just purchased a panel and after I showed this to my wife , she didn't give me any flak!She trusts your opinion much more than the ER doc she is married too. Could you please do an analysis of the Nature study regarding long COVID and lab findings? Thanks so much for all you do - it's so helpful top so many!
Thanks! I’m sure my wife would take your word over mine! Lol. I’ll take a deeper look at that study.
which panel did you purchase?
The moral of so many of these "stories" (research papers) is - Try to imagine how humans lived for the last few thousands years, and follow about 90% of it.
Be outside.
Occasional meat only, occasional sugar and oil.
Live kind of like a pauper.
Live slower.
More social interaction everywhere - the street, the train, office, homes.
Cook basically all your meals.
Don't over sanitise and clean everything.
Walk everywhere.
Buy less and work less.
Etc
I like it.
Don't romanticize the past too much. People had a lot lower life expectancy, then.
Clean water and vaccines made a huge difference in life expectancy.@@petersteenkamp
@@petersteenkamp Surprisingly that adage is only supported by evidence in some specific cases. There appears in bronze and iron age literature from the "near east" references to 3 scores and ten being a good life etc. Beyond literature there is no shortage of evidence from middens of teeth and bones of people with advanced age. It was and has not actually been rare for homo sapiens to live seventy or so years, in the same way that many other species live long lives. The industrial revolution has played some role in a deterioration of life expectancy, tied to horrible urban conditions etc. But this does not speak to many thousands of years of humans living more balanced lives in rural contexs.

Thank you ! From the practical point of view, it would be very useful to get some recommendations for in-home therapy devices. Not specific brands (I understand you can't do that), but categorized by design details such as: panels vs. suspended light-bulb, wavelength, power...I searched for this information, but couldn't find an independent and serious review.
Hi, Dr. I am a type 2 diabetic, and I noticed that the two times I participated in a week-long campout, my blood sugars were much better. Spending a week in the outdoors exposes one to a lot more red and NIR light. Now, I know that there is another large confounder: During outdoor campout I am more active, averaging over 20,000 steps per day on my pedometer, compared to around 7,000 steps per day in my usual day-to-day life. However, I think you may be onto something. I had previously bought a red/NIR lamp for my knees that used to hurt from time to time. I may try using it at other times to see if I notice any blood sugar reducing effects.
A component that most overlook is the impact on your circadian rhythms. I have a plant degree and those rhythms have been well studied and there is some research in mammals/humans showing it's importance, including in glucose metabolism. Your camping trip would have done wonders for getting that rhythm back in shape (as well as the increase activity that you observed). If you were to use this red light for any sort of treatment, I suggest doing it at the same time everyday and in the evening just before sleep. This is when the plant researchers found it benefits plants and it simulated sunset.
You are also ignoring the impact of ambient temperature. When you go from an AC controlled
The single best thing you can do for T2 diabetes can be summed up in three words:
Don't.
Eat.
Carbs.
It really is that freaking simple. The diabetes-industrial complex knows that a patient cured is a customer lost.
maybe I can help as a fellow "sweet friend"....to remove the confounding variable as I had to CUT DOWN on my exercise and activity due to too much. And the red light (even more than that, IV Ozone and HBOT...largely dropped insulin requirements by 2-4 sliding scale parameters!
I have bought it some time ago and the one thing that I have noticed is that my migraines (that I was getting regularly) are no longer coming back. I might have incidentally a little bit of a headache but nothing that lasts longer than an hour or two. Before I had headaches of many hours of days (with each month one bout of a migraine of 3 days). I hae also noticed that my levels of energy are slightly higher. Three interesting facts: when my family member was sick with flu with a lot of coughing I set it up for her - and after half an hour she stopped coughing constantly (to only once every couple of minutes a slight cough). So it dit something to her lungs that the production of phlegm was was much slower. Second thing, actually a warning too, I have heavy menstrual bleeding and I am usually in a lot of pain. I thought I could use this light on my lower abdomen. But the pain was not better because of this - and my period lasted longer and I got even a lot of pain afterwards (a couple of days). So I cannot recommend if for that purposes. Third of all, I had allergies and inflammation in my body my whole life and it is normal for my to have enlaged lymphatic knots (mainly under my jaw). After using this light it completely went away which was shocking to my. For the first time in my life I could really squeeze my neck without wincing,
I have just ordered a red lamp as I live in the UK. When it gets to December we are lucky to get 6 hours of sunlight and invariably many winter days are cloudy or raining. I have got my Hba1c down to 5.5 (at my worst it was 12). That dropped from 5.9 in the three months from May to September whereby I was out walking in the sun. After hearing this I think having a red lamp will only be beneficial even though I will continue to walk but of course I am more covered due to the temperature dropping. Thank you for explaining this clearly. I had heard of the benefits of red light but didn't know why now I know.
Which one did you get?
Which one dis you get please?
Field report: several months ago I tried switching from blackout sleeping to an LED light strip set to the dimmest red - expecting a worse sleep - and I'm actually much more rested.
Mostly just my face and arms are exposed and wattage is low but duration is high. It looks just like a photographic safelite so I'm guessing around 635nm wavelength.
Why tho.
Even ancient humans used to sleep in dark caves
I've retired to southern AZ. No shortage of sun here. I do feel better when I have a chance to get outside and I have not only lost weight, but my blood sugar level is lower. This all makes total sense to me. The internet is a wonderful source of information. Thank you for posting this.

Yet another informative & pertinent video about sunlight and health Doc! Thanks for these important videos! I am sending this one over to my cousin (M.D.) for viewing! Hope that all is well with you & your family!
That is a new addition to my knowledge about red and near red light lamps. If you live in Northen Europe, going out in sunlight from mid October is a dream which never comes true. Redlight and nearread lamps make sense to have
All red lights on my next Christmas tree! This is an amazing discovery. I do try to get out more often to get as much natural D3 as I can, and supplement for it as well (maintain ~ 70 ng/mL D 25-hydroxy). Now I'm off to order some red lights. Thank you for your explanation and posting this.
HAHAHAHAH that's great! We should call our Christmas trees, rooms, etc...'Roxanne' ... :)
This mechanism should also improve fatty acid metabolism, right? Not just sugar metabolism? If it's the electron transport chain that's being helped, that should mean both glycolysis and beta oxidation should benefit, correct?
That would appear to be the case, although it wasn’t directly measured.
Great I was just listening to this as a podcast while working in the backyard in the sun ☀️.
I greatly appreciate MedCram videos, especially on red light therapy. One correction: in the Cellular Respiration diagram the word “glycolysis” is misspelled. (Sorry, It’s the English teacher in me.) I have type 1 diabetes and own a Red Man model red light. I’m going to get back into the habit of using it again based on the results of this study. Thank you.
Yes. I noticed.
@@Medcram There may be no more common demonstration of confirmation bias: we read what we have just written and it looks good until we send it on its way.
TYVM! This is an interest of mine. Awesome, description of the various applications of light therapy. I'm learning so much more on this from you.
Great info. You should upload just the last few minutes of the video like every day, so that information will (hopefully) reach more people. Also consider making more shorts of your words of wisdom.
Great channel!
Another great finding, thanks for sharing doc!
Yes! Excellent. Answers some questions RE: NIR exposures that have been swirling around, and poses more. This summer I have been very intent on increasing outside activity, to get NIR increased. I had been very curious about just HOW NIR to the brain induced melatonin within mitochondria, this information helped scratch that persistent itch! Now, I intend to increase nightly campfire viewing as much as I can, in hopes that NIR and visible red light can better access cells even after sundown. This should help curb my common screen viewing habits before bed. I am coming to more fully see that we have been so very dependent through countless millennia of adaptation outside, and around campfire evenings, that we must be harming many acquired beneficial effects. Diet and other lifestyle modifications more in line with prehistoric living conditions need far more clarification to benefit our paths forward IMHO. Thank you for this important clarification!
I'm a plant scientist and we use far red light to impact the circadian rhythm in plants. Nearly all, if not all, plants and animals have a circadian rhythm and I believe this far red light exposure in this experiment was triggering that cycle. The theory is that the setting sun gives that burst of extra red light. Since you have trouble with sleep, might I suggest if you wanted to use this treatment on yourself, use it in the evening to help maintain your natural circadian rhythm.
Leave it to Roger Seheult to bring us yet another of the most surprising and fascinating research findings.
I can't even imagine the quality of medicine if all doctors kept themselves this well informed and dug this deep.👏
I'm still speculating that the improved metabolism is due to light energy being used to produce melatonin in the skin. Melatonin has been shown to increase atp production because of reduced ros generation.
The water viscocity claim is based on one cited paper and is only a hypohesis. Viscosity may reduce with light, but it was not shown that is what increases atp.
Since I saw your videos on light I have been spending more time outdoors. I sit out side and work on my laptop and work in the garden more, I really have enjoyed this change. "Get outside!" Great message, Thanks!
That is awesome!
Could be nice to have an explanation about the devices and their use at home. Any advice? Thanks.
I would like to. But when we do that, we run the risk of appearing that we are endorsing products. I don’t have one and I don’t know if I would buy one. But I am trying to get outside more.
@@Medcram Thanks to your teachings about sunlight as medicine it's almost a year now that I go out for a walk in the sun every morning.
Very promising research! And many redlight devices available for consumer purchase have both red light and NIR.
I am definitely using mine front and back head and torso every day now that days are getting shorter and I am outside less frequently.
what device did you purchase? I'm about to buy one from reddotlight (what bryan johnson uses, seems legit good) but it's like 250 for device+delivery from china and seems big enough for just the face or perhaps face and upper torso
thanks! great review of new research…I listened while basking under my red lamp -which I purchased after your lecture @ the benefits of light therapy -so enjoyable😃
As someone with a scientific education i really appreciate the break down of the graph. Prior to the explanation i could have easily assumed what you warned against at the end of this video.
I ate pavlova last night for dessert. I should have used my near infrared lights and infrared light. I needed this video last night. Thank you for these excellent videos.
I have ME/CFS & Long Covid. Used a high quality red light consistently for months in a row. I never did know if it was doing anything. Didn't seem to help my wrecked metabolic functioning. I guess if the studies are saying it helps, I should keep at it.
Thanks so much, very informative!
It seems that most of us have been deprived of long-duration, low-intensity red/IR light exposure over the past few years as we've transitioned from broad-spectrum incandescent light bulbs to LED bulbs (most of which emit very little energy above 700 nm). Although it's interesting to consider high-intensity, short-duration therapy and its potential effects, perhaps we should prioritize study of any effects that might have resulted from the change in indoor light exposure many/most humans have already experienced. Perhaps incandescent bulb use should not be eliminated but should be limited to cold/dark seasons when the heat they generate is not wasted (and their light compensates for lower sunlight exposure during those seasons).
Incandescent light bulbs should have never been determined by the government to be removed from society because the light emitted is healthy compared to the horrible, artificial white light LED emits. Similar to their food pyramid which is also poor advice.
Does this mean it would be beneficial to get this light before eating meals?
I’m thinking so
Reinforced by your data on mid IR .. I run in Texas at 8am for 90 minutes shirt off and 40 minutes at 5pm. 130 minutes of MIR, I also run in a,park by a lake so plenty of green to reflect the IR. I was on my morning run when I listened to your podcast. I run when uv Index < 5, with 5000iu of vit d .. my levels are good but I would have expected “optimal” .. thank you .. made me feel validated this morning.
I have a near infra-red light that I use on my testicles for testosterone. (10 minutes per day 5x a week) I’m 72. It brought up my testosterone from 300 to 1000 and free testosterone from 30 to 102 in 3 months.
I have not used it for my insulin resistance. I’ll try it using it with my CGM and see if it helps. I was walking on the beach for an hour a day in Florida but didn’t see a noticeable difference. I did just try it and my reading went from 146 t0 130, but I would need to do it a number of times to confirm it as not being a coincidence.
Thanks for sharing this!
We’ll that interesting
Thanks for this dude. I knew about it and I have been doing it from time to time also, but I was not sure about it so I was slacking of and I do not go and do testing regularly, so did not have any good confirmation that it actually worked.
But now I for sure am going to be doing this for ever.
What wavelength NIR? What power, distance etc. please? Any reliable information?
@@bengurion5285 Yeah, this dude should give more information.
I checked after reading this and this thing is controversial. I can not find anyone who can prove this works in humans. But a lot of people who say they have tried and done blood work and got no more test.
So please, If he can prove this a lot of people would benefit to know more.
One thing i noticed while checking up on what others have tried is most seem to way over do it. As in pretty much cooking there balls. It seems that just enough is key.
Maybe he has stumbled on the right dose. As he said only 10 min 5 x week. I am going to try it anyway.
When I used to try this I did get benefits, but I think I did to much and lost them.
But while it worked I did notice a massive increased libido though, to an annoying degree it think that is why I was slacking of in doing it or I just over cooking them.
I wish it was possible to get topped out test levels, to get the recovery and mental drive and confidence but without also way higher libido.
Because I just do not want to be thinking so much about things like that, I have things to do and at a point that type of distraction is just to much.
Sir, I just wanted to ask you, if Melatonin mitigates ROS, has annyone ever tried infusion of melatonin, to say help with pneumonia and stuff? Shouldn't that work theoretically?
I have read melatonin has been used successfully in early treatment trials.
Looking forward commercial product recommendations. Here in PNW, it is highly dark, cloudy and rainy all day long
absolutely amazing - well done and many thanks.
Wow! Another great video guys! Yet another reason that living near Canadian/US border I feel fantastic in the summer and crappy in the dead of winter. Had tried SAD lamp which helps with waking up in the morning, but I'm hopeful that getting a RED/IR therapy device could help a lot in the winter!
I'm Scandinavian and live on the same latitude as southern Alaska, and this will be my first winter with a red light panel! I think it will do wonders
@@Chiburi It made a difference to me last winter, whilst a SAD lamp did not have an effect. I live in northern England.
@@calluna5030 Interesting! I have recently incorporated grounding in my day to day life as well, I think it's had some noticeable effect on a tendonitis issue I have. And also, structured water
This raises several interesting questions
1) How much red light is in typical incandescent bulbs/fluorescent bulbs/sun? White light also contains red light, so it would be interesting to see if there is any benefit to cranking up light in general (RIP electricity bill).
2) This study doesn't consider other frequencies. Do they have minimal effect? Negative effect? Something else?
3) Last I recall, red light doesn't penetrate as far as IR, so is the effect mostly skin deep? There's a measurable CO2 increase, so it's presumably non trivial at least.
Why not a red light?
If you can get incandescent bulbs.. which you can online or if you have a stash. I don't know the amount, but there is some.. I don't know if there is enough for this kind of effect ; although I do know some folks who do feel better just using them for bright lighting during daylight hours. Flourescent lights more blue, less/little red and have awful flicker - which is a whole 'nother beast..
Awesome information, and the sort of thing that not only passes aling valuable information, but also shows us non medical folks that there are dedicated / smart people woeking on very useful, non-drug therapies snd the general understanding of the complex systems of the human body and health..
INTELLIGENCE is the most beautiful of the Arts.
Do we need to be concerned about OTC devices that state a certain wavelength but don't get calibrated? Or are the damaging wavelengths far enough away that it is not a concern for our skin?
Can you recommend a few good red light products ? Thanks.
This is the first video on this topic I've seen that is evidence based and quotes light intensity. Well done!
The big question has to be: What's the difference between one of those expensive red light devices and a 20-minute midday stroll? Sunlight will provide 1-5mW/cm2 compared to 0.1-50 mW/cm2 for one of those light boxes (depending on the box).
So someone needs to invent a "red light exercise jacket" to boost exercise tolerance!
They have jackets even mobile battery operated lol
Great video. The part I don't get is the proposed mechanism "reduction in viscosity of water". Given that this cannot be meaningful due to temperature alone. The reduction in viscosity must be thru alteration of the intra-mitochondrial fluid composition. Can you elaborate?
Yes this was my first thought too. What is the MECHANISM? How does 670 nm radiation reduce viscosity of water? Has this been tested extra-cellularly? My general principal is 'No mechanism, no effect.".
I can’t. I was just as surprised as you are to discover that that’s what they think the mechanism is. One area topic that I am interested in. Is this idea of structured water that I’ve heard about, but have not investigated.
Would a person of darker complexion or more pigmentation require more light or a different frequency to get the same results? How does one go about determining the proper duration, frequency and intensity of red light that is required? Are there other studies out there that might address some of these questions? How do you determine if you’re over exposing yourself to red light therapy? Great video thanks for a clear explanation regarding the work within the mitochondria.
I wonder if that is what happens in structured water produced by bulletproof coffee.

Im an outdoor worker, lots of sun. I dont consume a lot of sugar. Have high sugar level. Very poor insulin sensitivity.
Red light ( 650 to 800nm ) stimulate mitochondrial respiration.
670 I'm and other longer wavelengths of red/ infrared light -increases ATP production in which requires more fuel, since glucose is the primary fuel, thus red light reduces sysrptemic glucose concentration. This can help in diabetic management and weight loss.

I wonder how the red light therapy reduction in serum glucose compares with a 10' post prandial walk.
I wonder how enduring this effect is? Iow, would a treatment once a week offer any practical benefits or would treatment every day or every hour be required?
Nowadays, red NIR lamps are popular for health improvement, isn't a better option for example a halogen bulb in an office desk lamp with corresponding power? The spectrum of these bulbs is much wider and mainly closer to the sun... and the price is a bargain
Thanks for the reminder. As we're coming into fall now, I need to start using my red light lamps in the morning before work. I'd put them away during summer.
I would use the red light at night or later in the afternoon.
Natural sunlight is in the blue spectrum in the mornings which is designed to stimulate function and be alert. Whereas the red orange spectrum is what the setting sun emits signaling the body to produce melatonin and fall asleep. Thus natural morning blue light and evening red maintains our healthy circadian rhythm. We are now viewing our blue light emitting devices at night creating unnatural exposure. Wearing blue light filter glasses and using incandescant bulbs at night is healthier.
Dr. Seheult, thanks for this report.
I have been experimenting with a radiant heater, which normally produces orange light (590 - 620nm). Orange is a shorter wavelength and a more energetic light than red light (620 - 750nm). When I reduce the power to the filament of the radiant heater, it becomes dim however, never turns red. This I don't understand.
One question is, if skin was illuminated in the red as was done in the study you discussed, and that skin had a cancer on it, would the red light help or harm the cancer lesion ? Secondly, would a higher frequency of light (orange) be more lightly to affect cancer metabolism differently than healthy-cell metabolism ?
I suspect that red and infrared frequencies of light are healthy. In the infrared frequencies I suspect energy utilitization is augmented when the cytochromes in the electron transport chain absorb the photons and move to a more exited stated that speed electron transport in a process similar to plant photosystem 1
Would red light be ok for people with lupus and other autoimmune diseases?
This is like asking is it healthy to get sun exposure when sick?
Might this help someone with drastically reduced lung capacity?
Very well presented analytical deconstruction of this study. Thank you. Curious as to the basis of the conclusion as to mechanism of action.
Does a wide area of the body need to be exposed to red light therapy or nir light therapy to get the systemic benefits? Or can it be used only on a specific part of the body for targeted pain relief and still benefit the whole body?
How does using sunscreen affect this?
Any recommendations for light therapy devices? winter is upon us.
Agree give us a good brand name or suggestion for products I saw many of these devices at a skincare show they are thousands of dollars.
I would highly recommend checking out Alex Fergus's Red Light Therapy channel. Very in depth reviews of almost all R/NIR light therapy products on the market. For the type of effect discussed in this video, look for a body panel.
Thanks for the great content. It seems to me that there’s no reason that we shouldn’t be able to get all these benefits from just sitting in front of the heater lamp that they use for reptiles. One of those lightbulbs is like 20 bucks. That should expose you to the full spectrum of infrared, near infrared, and red light. is there some reason or advantage to using LED specialty lamps with two or three fixed wavelengths? If it’s just basically thermal absorption for the water in the mitochondria (why doesn’t affect the rest of the water in the body? Or does it? It must) then, to a certain extent the wave length shouldn’t be that important.
Interesting.
Sunlight is great, no doubt; and you've made that case elsewhere. But, regarding indoor lighting or lamps: white light includes all colors, including red light. So at the right intensity, area, time, and distance from the body, couldn't ordinary, white light give the same benefit? (Granted, of course, that one or more of those factors will need adjusted versus a red-light lamp, since the red frequencies are but a subpart of white light.)
Yes..theoretically. LEDs give off no infrared however.
Wonderful explanation which provided wonderful data from a randomized double-blind control study. The fine art of a good methods section in any research study. :-)
Amazing deep dive. Love. Thank you for sharing. Curious, so the light of the sun itself is the healing element, so what about taking vitamin D then.
Taking vitamin D is fine, but it is not sufficient
Should we use red therapy? At my local tanning salon, they charge to use the red lights. Im not sure how significant the test results were that you mentioned..
The red light only covers one square ft of your back, would there be a more pronounced effect covering more of the body?
Second, how long does the increased BMR last for?
In the eyes a week after one 3 minute exposure in the morning of 670 nm light if you are 40 or over, then you need to do it again
Amazing. Gid is light and in him there is no darkness at all. The sun has risen with healing in his wings.
What brand of red light do you recommend?

How are ketones used in the mitochondria to produce energy? Do the mitochondria have a greater affinity to glucose or ketone?
Ty brother. Medicare needs to pay for it and physicians need to give photobiomodulation devices billing codes in the AMA.
hmmpf. they only want to pay for things that will add to their profit margin and keep you a lifelong customer. i.e statins..
Thank you for delving into this study and explaining the effects of red light on the mitochondrial mechanism. Have or will you produce a video on the synergistic effects of red light with Methylene Blue? Apparently it's quite profound.
If photoexcited, MB can generate reactive oxygen species and genotoxic photodegradation products leading to DNA damage.
Are you referring to Low Dose Methylene Blue? Quite a different outcome tohigher dosages

Best lecturer! Love all your vids
Those GTT blood glucose levels seem to be fairly low. It looks like none of the people studied were diabetics. It would be interesting to see the same study with diabetics both on medication and those who manage their glucose by diet only.
The blood glucose levels were elevated above the baseline. This was on healthy subjects.
@@Medcram There's a vast difference between healthy individuals with elevated glucose and diabetics, but media and marketing are proposing that red lights *cure* diabetes.
There's a long distance between treating wrinkles and skin conditions with infrared-range light, including diabetic lesions, to propose red lights as a treatment for diabetes itself, which is what the comments to the video make it look like - and Google results leading to wellness websites, making red lights good for *everything.* Bone growth, hair repair, acne, oral care, psoriasis. Only skin issues treatments have scientific backup. Infrared light can penetrate the body several centimetres deep, but red light, just 1 to 3 millimeters.
So, no peer-reviewed papers supporting this claim, but one study uploaded to a pre-print service and to a social network. And the cohort study, is not about red light, but *outdoor temperature and bright sunlight,* which included triglycerides - and physical activity? Were the subjects just lying taking sun baths? In England and the Netherlands?
In a country where people die due to insulin being outrageously expensive, proposing red lights as a treatment is borderline irresponsible. The last analogy was flawed, to say the least. Chilean here. The comparison between life in developed and developing countries disregards all the other differences: diet, climate, social activities - the existence of public/affordable healthcare systems. Guess what: there are plenty of diabetics in Chile, and, interestingly, in American First Nations, who are about three times more likely to get diabetes than the white population. Attributing Americans' obesity and diabetes rates to lack of outdoors activity and sunlight, in a country where even bread is actually cake, is fallacious.
Are we already into quackery territory, or can we still stop before having to report the next videos for misinformation?
Librarian here. Please, prove me wrong with peer-reviewed sources.
Would you recommend the biomax product for retina healing as well as other parts of the body
What’s a good red light to get?
I've been researching this, and one thing I'll say is the power density manufacturers list aren't always what independent labs find. I would look for some independent testing of output, but suffice it to say that many of these devices probably are helping, even as they may not be at the power density levels that they claim, and we should keep it In nind because the peer reviewed papers probably are more accurate in the stated power density levels used..
Thanks a lot, Dr. Roger for this excellent podcast.
This opens the topic of sunlight and its healthy effects on human body.
Red and infrared light are beneficial to the human body.
I have been using a red light of 660 nm LED Photobiomodulation therapy for wound healing since 1996 and I have a rich experience of almost 90% success.
Amongst these I would like to stress upon the good results I achieved in diabetic patients. I have always selected patients for this therapy.
I would like to have an opinion from you Dr. Roger on the following experience of mine :
I have seen that wound healing improved even in those patients who did not keep their blood sugars controlled. Would it be that the red light exposure helped reduce local blood sugars in the open wounds much more than the actual blood sugar level in mmols/dl?
Dr. Roger, can you please explain?
Dr. Bipin Deshpande,
Dermatologist,
INDIA.
That’s interesting. I’m not sure. It seems also that it might give more local energy in the form of ATP for wound healing but I know that they are using it here as well.
Thanks for your reply Dr. Roger Seheult@@Medcram
You do an amazing job explaining concepts very clearly and with diagrams. Those help one understand and visualize what you are teaching. I like how you reference to your other videos like the Covid-19 and light, Light as Medicine and how it ties to this particular video. Well done. I learn so much from you Doctor.
You're very welcome!
I am wondering if sunscreen use has any effect.
Very interesting information! Thank you.
Is there a version of this presentation that would be appropriate for patients?
They may benefit from this format. Don’t have another version as yet.
What kind of red light? I have a far infared light heating pad from my neck to my lower spine.
Do home red light devices increase risk of cell damage/cancer?
Northern latitudes here. I get out a lot! Work out five days a week, plus bought my own red light/Nir unit and use it. Plus go to one of our gums locations where they have full red light treatment rooms. I am hoping it might help healing? I use a NIT bulb for my restless legs and it really helps.
