I wonder if glass windows would block out the benefits?
- mjevans 9y agoAnecdotally, a lot of window products have built in films, coatings, or dopants that reduce UV exposure and possibly other portions of the spectrum. I would /guess/ that pure (greenhouse?) glass, maybe not even visibly transparent, would be effective. Both could be worth studying if someone hasn't already.
- AstralStorm 9y agoGlass itself blocks a lot of UV. Even not doped. There exist optically transparent plastics that do not.

- rollulus 9y agoYes it does block [1]. Coincidentally I was discussing this with a co-worker last week. [1]: http://www.sciencefocus.com/qa/can-you-absorb-vitamin-d-through-window http://www.sciencefocus.com/qa/can-you-absorb-vitamin-d-thro...
- Gibbon1 9y agoOrdinary window glass blocks 90% of UV-B which is needed to produce VitD. I do remember reading years ago about a sanitarium in the late 1800's - early 1900 where the windows in the sun rooms were quartz glass.
