Your body makes its own vitamin D in response to sunlight exposure.
- ErikAugust 6y agoWell, yes. But does the region have significantly less sunlight than others? Or is it just the people in question didn't get nearly as much exposure?
- liability 6y agoLatitude, local geography and weather will all play a role in how much sunlight you get. If you're living in a valley you can have much shorter days than your latitude would suggest. And if the weather is shitty enough to keep you inside much of the year that will obviously have an impact.
- mixmastamyk 6y agoYes, age and skin color also have a large influence on whether your body can utilize the sunlight you receive.
- trhway 6y agoYep, there were studies that Somali refugee populations in MN and Sweden have very low vitamin D levels (and associated high rate of children autism)
- selimthegrim 6y agoHow does the autism follow?
- trhway 6y agowhile we don't know "how", there is growing body of work showing a correlation between low level vitamin D - in particular winter pregnancies in Northern Europe countries correlate with higher rate of autism as well as the mentioned studies of the 2 clusters of Somali refugees.
- oxymoran 6y agoNot all sunlight exposure works though. It needs to have enough UV-B in it. And that’s dictated by the time of year, the location, and the time of day. In some places, you may only get an hour or so of the right kind of rays.
