I'm wondering how much natural vitamin D production can be expected by the exposure of only the face to bright sunshine in the winter, when the rest of the skin is covered by clothing?

    Not much at all. In fact during the summer you must expose large areas of skin to make enough For instance your entire back or most all of your legs. Just arms and face are not enough.

    I have to think there would be a time factor as well. Square inches of skin per hour. Something like that.

    Maybe this will help answer some of your questions http://www.vitamindcouncil.org/about-vitamin-d/how-do-i-get-the-vitamin-d-my-body-needs/. (I suppose you should keep in mind that things maybe different for someone in a disease state. Meaning they might have to stay in the sun longer than a healthy person because it takes a lot of Vitamin D to repair. This is a guess on my part. We already know that the bigger you are the more Vitamin D you need, so that is another factor.)

    I see that glass blocks UVB rays. I’m also wondering if any type of plexiglass or even thin plastic sheet would allow UVB rays to pass through?
