That’s a good point. The article mentioned needing only 3-8 minutes with 25% skin exposed to get enough vitamin D in Boston. I wonder how much you’d need in places with less sunlight.
…It turns out that you don’t need high doses of sun to get sufficient vitamin D. A 2010 study calculated that between April and October, someone in Boston with 25 percent of their skin exposed would need between three and eight minutes of sunlight per day to get enough. Of course, in the winter it might be challenging to find even this amount of sun at some latitudes.
