Getting sunlight in the morning, in particular, seems important. Even in winter months, I'll go outside for 30 minutes or so in nothing but shorts and do farmer walks, etc. and feel great throughout the day.

In winter, in the more northerly latitudes, being outside is not sufficient, because of the angle at which the sun ray hit, the skin cannot make vitamin D.

I highly recommend watching this video:

Sunlight gives us vitamin D and nitric oxide (which improves blood flow and reduces hypertension). Vitamin D is crucial for the functioning of our immune systems, and the 1000IU dosage of many supplements is laughably small. A light skinned person in a singlet standing outside at noon for 30 minutes will produce between 10,000IU and 20,000IU in their skin. I would recommend supplementing 5,000IU vitamin D while also getting some exposure in the morning or afternoon (but avoiding the sun when it is high in the sky).

Before the vitamin D link was so widely reported, I remember seeing a bunch of comments online (including HN) from people saying things along the lines of "We've been self-isolating at home since January, only bought things online, and STILL got sick!" I'm not a professional and this is just me spouting ideas, but I wonder if this is one reason why America is so hard hit compared to Asia. Americans generally commute…

you can sanity-check your suspicion by looking at the data across countries. peru, spain, mexico and brazil should be enough to show that your idea is probably not correct

>In other words, in an observational study design, it cannot be excluded that VitD deficiency represents a surrogate marker for a general micronutrient deficiency, which in turn reflects only the patient’s overall health status.

From the authors of one of the cited papers. I.e. if you are in generally poor health already, COVID-19 is more likely to kill you.

It's unfortunate that it is not simple to get regular tests for vitamin and mineral deficiencies. The whole process seems to be stuck behind the doctor appointment firewall. This might be one of the reasons why Theranos was so readily believed. As the quantified self movement that gained popularity around the same time showed, there's an appetite in certain segments of the population for this type of testing and trac…

This does exist now. Places like https://www.everlywell.com/ will test all sorts of things for you over the internet -- no doctor required.

Yeah that's a good point. Going outside when the sun is high would probably allow that person to not resort to shorts.

In case you live in a northern climate and want to catch some rays through a window. Glass filters >90% of the rays that cause vitamin D production.

Not only that, but a large fraction of the English-speaking northern hemisphere does not receive enough sunlight in winter months for the skin to produce Vitamin D.

I must admit I was completely ignorant of the effects of Vitamin D deficiency on common illnesses such as the flu as well as how unbelievably common that deficiency is for people living in much of the northern hemisphere. Will it cure COVID19? No. But do I think there's a decent chance it will improve my outcome while simultaneously improving my ability to fight off other viruses. I am honestly completely shocked tha…

The problem is that vitamin D absorption is one of those things linked to ethnicity. It is very basic and undisputed science that lower melanin in skin = higher vitamin D absorption. No European educational institution or government wants to publicise research highlighting that ethnic groups indigenous to the northern hemisphere are more suited to the natural environment they are endemic too, and less likely to have…

Wonder if there is also a connection with the declining popularity of cow's milk, which is typically fortified with vitamins A & D. In primary school, cow's milk have become less common due to increased awareness that different ethnic groups have different tolerances for lactose. Unfortunately, it appears the groups that would benefit the most from more vitamin D are also the ones most likely to be lactose intolerant, and thus not drinking the milk fortified with vitamin D.
