That is probably likely!!
We take a lot more Vitamin D than that, too - especially since we’ve been stuck teleworking at home, during these endless, hot months.
When I worked on-site, I would go outside on breaks and get some sun. My perception is that, for some reason, when people work from home, they don’t even give themselves breaks - they just stay glued to the computer.
We’ve got another month or so of optimal Sun, at least in my area. Everybody should go out and EXPOSE themselves to it, as often as possible.
