Yeah, you would think, but from the research I did about the Vit D
thing, it may not quite be that easy. For example, if you're wearing a
long sleeve shirt and long pants, it'll take much longer. The 15
minutes is a general guideline and apparently it means with both legs
and arms exposed, i.e., like when you're lying on the beach in a
swimsuit.
In winter those in Northern climates, particularly those with darker
skin, actually have a very difficult time keeping Vit D levels adequate
due to the slant of the sun and the fact we tend to cover up all but
our face when it's nippy out.
As for me, I wear sunscreen under my foundation year round, so even for
basic daily things, I'm effectively blocking vit D. And my previous
routine, for days when I am out in a bathing suit or clothes leaving my
arms and legs exposed, I put the sunscreen on 15 minutes before leaving
the house, to give it time to absorb, as is recommended. This is the
habit I'm now considering changing: instead of putting it on before I
leave, perhaps it's wiser to put it on 15 minutes after I've already
been outdoors.
