MS is another disease that correlates highly with high latitudes living (during childhood). By late teen years the risk factor for it is already baked in. But I think some sun improves everything. People who go for a short walk with long sleeves, hats and sunscreen make me laugh. I recently got plantar fasciitis and can't walk much, it''s too cold to stand still outdoors so getting little sunlight. Its killing me (mentally and maybe physically).

As a pale but not yet feeble one, I did not know what my Vitamin D levels were, but guessed that they were not high, so started 1000 i/u per day supplementation. After 15 months I got a test which showed 26 ng/mL, which I considered inadequate. So I started sunbathing for 20 min before 9 am when sun and time permitted, and supplementation up to 5000 i/u on non sunbathing days. After 7 months of that my vit D test showed 56 ng/mL. I also have a modest suntan for the first time in 73 years! Sunbathing also seems to improve sleep, and mood. It just feels good. I have never tested positive for Covid despite having it in the house three times. None of this proves anything but I like to feel in charge of events and this regime achieves this. Thanks for the advice.

Not all UV wavelengths go through windows: "Standard window glass, according to the International Ultraviolet Association, will allow UV-A to pass through while almost 100% of the UV-B and UV-C light is blocked." So we need to be careful of extrapolating between indoors and outdoors. However, the light itself absolutely must help with overall mood. My house has NO south-facing windows and very small west-facing ones and I'm in Olympia. It is the most ridiculous design!

Yes.

a century ago people with tuberculosis were put out in the sunshine, all wrapped up depending on the weather some people recovered. The town I live in used to have such institutions.

I’ve had a history of chronic bronchitis that lingers. I’ve also had a history of Vitamin D deficiency. A comprehensive medical exam in 2018 showed low Vitamin D and the doctor told me to take OTC Vitamin D. I did my research and started taking D3, but I wasn’t sure of the dosage. Anyway, I wasn’t really diligent and in 2019 I had a weird respiratory infection that lasted about six weeks. I recovered but when the COVID pandemic came about, I did more research and started taking 10,000 iu of D3 combined with K2. In 2022, I took a home Vitamin D test and my level was optimal at 76 ng/mL. Ironically, since 2020, I haven’t had one cold and zero respiratory issues. Also, coincidentally, I moved to a house with a very large back field in southern Nevada and walk my dogs every day. So starting in 2020, I was taking an increased dose of Vitamin D3 and getting more regular daily sunlight, not to mention taking daily Vitamin C and Zinc. Maybe it’s just a placebo effect but whatever it is, I’ll keep it up!

You're killing it on medical and science. Bravo. You're killing it. No politicization, just science and the limitations of science / technology / medicine.

I'm 78, haven't been vaxed, haven't had Covid19 and am on 50,000 iu a week due to an autoimmune disease. I believe that it's kept me well, I know that I've been exposed 3 times having had close contact. I'm certainly a believer.

I start to experience Seasonal affective disorder (S.A.D.)each year around late November/early December as our sunlight exposure drops significantly with the shortest days of the year. As the spring arrives my moods improve like clockwork. No doubt in my mind that sunlight is the elixir most of us crave and need. Good vid, thx.

The mixture of scientific rigor and open minded consideration of alternatives which you present is truly excellent. You have been meticulous in distinguishing correlation from causation, plausible mechanisms of action from demonstrated mechanisms, informed speculation from proven interventions. I appreciate your promotion of sleep, sunlight, and even things like "forest bathing" as "there is reason to believe this might help and it's very unlikely to harm" as an alternative or complement to the "distill everything into a pill" approach - but you wait for confirmation before claiming effectiveness. What other channel can integrate both forest bathing and AT II ---> AT 1,7 via ACE2 pathways, each in their respective place? During the more acute phases of the pandemic, your channel was a breath of air which helped me process what was going on. I don't follow as closely now, but the sound of your opening music still evokes a very positive feeling in me, like a memory of seeing a light in a time of darkness. It's likely the strongest musical cue I have that takes me back to the depths of the pandemic (and probably still will a decade hence if I'm around), and I'm glad that it also invokes hope that with science and rationality, balanced by lack of dogma, we humans can persevere.

I was 57, reasonable health, pre-diabetic and just over the Obese line and live coastal SoCal. I rarely get sick. I did all of this because of a study at Harvard which a family member was aware of. That study was never released... It doesn't sit well with me that the protein ratios in C-19 are round numbers (not typical in natural similar viruses).

If the govt. had pushed ALL known methods of resisting Covid in addition to the vaccine, such as methods to improve your own immune system, it would have been better regarded as an honest agent. But unfortunately, even before the vaccine came out, there was no mention about alternate methods that a person could do for themselves to help make their immune system sharp. Not even for minors. Today, if you don't want the flu, the vaccine is pushed as the ONLY solution. I remember researching the CDC flu vaccine efficacy tests for my age group and was shocked that it was less than 40% (depending on the strain). They demonstrated a huge bias toward only the pharmaceutical industry as the ONLY option to resist Covid or the Flu. I stopped getting sick when I got my Vit D and Zinc levels proper several years back Coincidence?? Not based on what others have also been reporting. I'm not anti vaccine, but I believe the govt. should have outlined all possible methods that people could do for themselves to help prevent Covid, even if these methods were not as good as the vaccine, AND our govt. should have leveled with us about the true efficacy of the Flu vaccine over the years as well. Our govt. should be our independent source of accurate information, not solely an extension arm of the pharmaceutical industry.

Good Morning Dr. Seheult, As always, I hope all is well with you and your family. Thank you for always communicating things so clearly. I've been listening to your reports/updates since the beginning of the Pandemic. What you have shared has been life changing and I often share what I learn to help others as we live through these very trying times. I'm an black male who embraced the profound evidence based conclusions regarding supplementing with higher doses of Vitamin D3. Based on the evidence being presented around the world my family increased our Vitamin D levels to 87ng/ml to 100ng/ml, at the very beginning of the Pandemic. We test our levels twice a year to ensure we main levels on the higher spectrum. I decided to put my trust in the research as billions of people do everyday with prescription medications. A, P-value of 0.001 is very significant. I decided to completely put my trust in what I concluded to be true, even down to the Indian study if we were ever exposed... outcomes proved highly beneficial within 3 days, attributed to optimum D levels as well. I'm an advocate for sun exposre, whoever, given our cultural realities around the world, adequate sun exposure for black people and people with darker skin tones in general is a major behavioral shift for not only the afore mentioned ethnic groups but for all groups, unless cultural norms dictate otherwise. However, in my efforts to defeat Vitamin D Deficiency globally, I have advocate for sun exposure (how ever much we may benefit as a race of people) in conjunction with optimized Vitamin D levels. I do have a few questions. Is the absorption and use of infrared radiation inhibited by darker skin as with UVB rays? If so, how much longer should people of color be exposed to sunlight in order to reap optimum benefit (mitochondria, melatonin, circadian)? Last question, If melatonin proves to be a blocker without prolonged sun exposure, does that mean, darker skinned people are limited once again due to the pigmentation of our skin color or should we drive and conduct additional trials on treating COVID-19 with doses similar to that in the Indian study, until we have a better treatment course? I ask this because black and brown people of all shades are still the highest risk groups of dying from COVID-19 because our Vitamin D levels are so very low? Lastly, what possible role does Vitamin D play in controlling ADE occurrence within monocytes causes massive inflammation all over the body? As always, THANK YOU FOR EVERYTHING! Me along with millions of others truly appreciate every second you give towards informing us on what we need to do to get healthy and maintain our health. Concerned Global Citizen,

Any part of the body detects any amount of light leaking into your room. Utter darkness and a cool room for optimum sleep. Hang heavy drapes. Think cave.

A High Carbohydrate Diet, like the Standard American Diet, will deplete the Body of Vitamin D, the B Vitamins, Vitamin A, and other nutrients necessary for proper functioning of the Immune System. It not only interferes with absorption of Vitamin D, but the resulting High Blood Sugar and Blood Insulin spikes from such a Diet result in Oxidative Stress that leads to Systemic Inflammation, taxing the Immune System and making these deficiencies worse. Over Decades, the Hyperinsulinemia from a High Carbohydrate Diet causes Insulin Resistance, leading to Hypertension, Fatty Liver Disease, Diabetes, Cardiovascular Disease (not surprised your Cardiologist recognized the association), Cancer, Kidney Disease, Autoimmune Diseases, and Dementia/Alzheimer’s. Extra Sunshine Exposure and Supplementing Vitamin D can be ineffective if the Dietary Root Cause is not addressed. A Healthy Ketogenic Whole Foods Diet combined with Intermittent Fasting is the best way to manage Blood Sugar and Insulin while obtaining the essential nutrients for optimal health. 👍

Thank you for continuing to provide these excellent presentations on COVID and health!

Vitamin D cannot be absorbed if there is a co-existing magnesium deficiency. There might have been Mg deficiencies in some of the participants in the supplement-study Vitamin-D-group, if so their vitamin D levels wouldn't respond to supplements. Magnesium deficiency is shockingly common. The authors should have verified serum levels AFTER supplementation and stratified analysis according to change in vitamin D status.

My D level was 118 last year. MD had my PTH checked and was WNL so no worries but backing off on the 10K I was taking. ; Narry a cold in the past 2 years. Work with Cvid pts too. They never checked ICU pts D status. Saddest times ever for medicine. Thanks for your education!

I have been taking vitamin d for many years as my level was at 9ng 5 years ago. I have been supplementing with an average of 5000ui since then and latest blood test showed my level now at 34ng a year ago. I have multivitamins along with extra d3 for my 3 kids. my 16 year old tested positive for covid in January and he then admitted to me he hadnt taken his vitamins. Out of 5 of us in the house, he was the only one who tested positive and was sick. The rest of us take vitamins including d3 and kept testing negative and never had any symptoms. I'm not saying its the Vitamins...but it really is too much of a coincidence not to believe personally.

It’s simple. Severe Covid causes Vitamin D deficiency. Severe Vitamin D deficiency causes other problems. Replacing the Vitamin D solves those other problems, but doesn’t effects Covid itself. But solving those other problems can reduce your risk of death by those other issues that are caused by severe lack of Vitamin D. However, Covid can still kill you, and cause other severe issues.

I suspected that this might be the case and I’ve already been telling my patients to get more sunshine and get outside.

I broke my ankle 3 years ago and I was diagnosed with Osteroperosis and low viatmin D levels. So I began taking 5,000iu of vitamin D3 daily. In the past I was always porne to upper-respiratory infections, but since starting vitamin D I've had far fewer colds (just one, compared to 3-4 per year) and the one I got did not leave me with bronchitis and coughing fits for weeks on end. After watching this video I'll try to get more UV as well.

EXCELLENT presentation.

It seems so obvious and in human's nature. I have a friend who recently was sick with Covid, a neighbour and it was a glorious sunny day and I told him he should spend time in the sun. He went back inside. He's had Covid 4 times now.

Early lockdowns in the big cities in the US kept people indoors. Parks and forest preserves were closed. Kids could not play in playgrounds. Completely opposite of what should have happened, and this was known by many people at the time, but went unheeded by public health officials. On purpose.

Excellent report!! I will even take notes. such helpful information and valuable for all aspects of life...just turned 55 and I sure can use this information in my life!!

It’s not a paradox. If you’re about to jump off a bridge actually having the bungee cord attached before you jump is much better than someone throwing it to you as you fall. Having high serum levels of vitamin D before infection is very protective. Treatment with very high doses of the bio effective form of vitamin D has been trialed and has shown some benefit but usually it’s too little too late. It takes time for the body to build up serum levels especially when some infections actively block the vitamin D receptors. There is a danger that the impression that taking supplements won’t help there for don’t bother will be the message people get from reports about ineffectiveness. The message should have been screamed from the rooftops to take vitamin D. It’s the one proven thing that exceeds the efficacy of the jabs the masks the hand sanitizers and social distancing.

I'm wondering if a more appropriate analogy for Vitamin D not being effective at improving things, if taken after, is that low vitamin D levels is simply the engine check light, and smashing the check light bulb with supplementation doesn't fix the problem.

Vitamin D is "low hanging fruit". It's one of those things that won't hurt (in reasonable amounts) and most people need as a supplement. If it has a beneficial effect on COVID outcomes, I figure that's "gravy"! I'm older and took 5000iu per day but that only got me to 27 ng/ml, so my doctor has me at 10000iu. I'll have it checked again in a couple of months. And I'm getting my NIR, too! 😁

Excellent deep dive into cause and effect. Thank you.

Given the relatively safe profile of vitamin D, most doctors are still sleeping at the wheel. 3,200 IU is still a bit of a joke. A number of people I know take 5,000 IU, but most can't even reach 40ng/mL. I now take 7,000 IU to reach 50 ng/mL which appears to be the optimum level for your immune system. But even still, you need auxiliary supplements, zinc, melatonin, omegs 3, NAC, tumeric etc. And on top of that walk 30 minutes in the sun, wearing as much clothing as you can stand, to cause heavy sweating. You get both UVA and boosting of your interferon. And this is for free. Maybe the only way to really battle Covid, meaning not suffer long Covid, is to boost your immune system, which is not the same as vaccines, such as mRNA. These very specific vaccines leaves your body completely unprotected as the virus mutates.

Thumbs up! I still wish you would understand how vitamin D goes through the body. The goal is not to get 25(OH)D3 levels up. The goal is to get 1,25(OH)2D3 to the VDRs to effect gene expression. The 25 form is the WORST form for this due to being tightly bound to VDBP. D3 itself enters cells where the 2 conversions take place allowing the 1,25 form to make it to the VDRs but D3 has a half-life of around 24 hours. The "paradox" disappears when you understand this.

Above the 74 parallel. UK is mostly above. I have been taking cod liver oil as a supplement for decades. I have also been taking 4000iu vitamin D daily since very early in the pandemic. I had hardly any symptoms when I had Omicron.

I have also read that exercise improves how well Vitamin D is converted to the active form. When the seasons warm, people are much more likely to get more exercise outside than when they are bound inside. Certainly the Melatonin benefits are real, but is it the dominant effect. Does exercise produce internal MIR radiation? The body definitely gets warmer with exercise.

thanks for breaking down all that scientific literature into such easy to understand language. Awesome!

Thank you-extremely informative- consice and Crystal clear even for non medical person.

Fascinating! I have read many things over the years that seemed to indicate health benefits from being out in the sun, yet all of the emphasis was on the danger of UVB exposure. This could be the explanation! Avoid UVB, but get lots of NIR! The anti-oxidative effect of melatonin also raises questions about melatonin supplementation. Thanks! I’m going outside now.

Since obese people have a lot of subcutaenous fat (which binds vitamin D to fatty tissue) it could perhaps explain why they are more prone to develop serious disease even though they take supplements. Second, it takes some time before vitamin d is broken down by the liver into a substance that increases your ng/mL (forgot what its exact name was but its used intravenously to patients who need a instant boost of vitamin d in blood system. So your lifestyle is more than a factor.

There are plenty of videos on KZread.

It’s a simple one to solve- when trying to invoke a rapid response, it takes a much higher initial dosing. First, it takes a bit of time to ramp-up melatonin and related levels and also at least 6000 IU upon acute onset to make a difference, which is substantially higher than many using/testing Vit-D in response rather prophylactically. Some use 10,000 IU for the first and second day, and then start trailing down to about 4,000 IU. There is a reason why hospitals often use a one-time massive 50,000 IU dose upon admittance (for entire week), and why 2,400 - 3,200 IU upon acute onset see little benefit. Also, that BJD is NOT independent of the Vitamin D pathway, since creation of Vit-D from sun is NOT an on/off switch. When you positively correlate it with sunlight exposure- even at slightly higher latitudes, you are STILL correlated with Vitamin-D exposure, as noted in that report.

Really interesting talk. Thank you!

amazing detective work, incredible that such a simple thing like benefits of sunlight is so difficult to figure out exactly

Even before watching the full video , I suggest that even Simple Simon could question whether all Vitamins D are equal . D3 and D2 are two separate forms that are synthesized differently .
