How did societies in northern regions historically get enough vitamin D? Yes they would have spend more time outdoors than we do now, but they’d also be mostly covered to keep themselves warm, so even on a rare day when it’s sunny they wouldn’t get much exposure.

- kolbe 9y agoThe way I understand it, if you're pale enough, there's more than enough sunshine in a dreary UK winter to get enough exposure. The problem is much more related to how we don't take advantage of it as a culture. Odds are, that the day on which you should be outside soaking in some rays is going to be a day that you cannot leave your office for more than a lunch.
