Irish winter provides enough vitamin d

wtf vitamin D has nothing to do with temperature. Just expose your ass to sunlight that's all it takes

>Just expose your ass to sunlight that's all it takes
That's not exactly how it works. UVB rays need to hit your skin with a certain intensity in order for you to produce vitamin d. That's a problem during winter because the angle of the sun is much lower then and the UVB intensity is a fraction of that during summer. Not the mention that clouds also reduce the UVB intensity up to 90% if they are really thick.
And now this article essentially claims that despite all these circumstances, there is still enough UVB to produce vitamin d during winter.

Now I have already asked my question in the OP, so if someone could give me some good input on that I'd really appreciate it since it's an interesting topic for me.

Anyone?

I dont understand what youre asking. Youve posted an article that answers your fucking question. Youve posted the answer and literally begged the question. Now go home brainlet.

>>9114577
Read the paper and you might find why.

I think my question now is a better one: why irish winter?

>>9114490
>winter
>Ireland

All right you dumb fuck. In this post >>9114577 I explained why it is very hard or even impossible to build vitamin d during winter in high latitudes.
If you read the article from to The Journal you will see that claim that it's the opposite and that it's very well possible to build vitamin d during winter in Ireland.
What I am asking is how would that be possible? The study abstract (I don't have access to the full study) doesn't says that it's possible to during winter, it says that people who enjoy more sun are less likely to be vit d deficient from what I understand. Does that mean that the news article is wrong? Does that mean that it is possible to build vitamin d in smaller, but still significant amounts? HOW MUCH VITAMIN D CAN YOU BUILD DURING WINTER ACCORDING TO THE STUDY, NOT THE NEWS ARTICLE???

Like I said, I don't have access to the full study and the abstract doesn't answer my questions. Also I am not a native english speaker, so I might have not understand everything right.


Also what's up with Irish winter? I am not from anywhere near there. I know England has winter, so I suppose Ireland has it too.

use scihub.io and read it.

maybe its the sample.

but note the article says that previously it was thought that english weather was fine for getting vitamin d so i dunno. depends on your sources.

>>9116885
Never heard of that. Thanks anon.

It's mostly align with what I have known about vitamin d production.

there is a reason the Irish have light skin and red hair

Vitamin D is a contentious field. Holick and vieth and a few others keep telling us that it's low in most of the world and that it's linked to a million immune disorders but they use shitty RIA assays to measure it. IOM reviewed all available evidence and said that we're generally fine, read the report

>>9116944
Do you have a link to the report?

GO OUTSIDE

Well obviously it's because the Irish are very pale. The paler your skin the more vitamin d you can produce. The people needing supplements there are the darkie migrants
