With you on considering the possible causation in other associated mitigating behaviors, but: > studying possible side-effects of universal, permanent mask wearing Can you suggest a model which would imply there are likely to be any side-effects? I'm also sortof baffled by the suggestion that there's anyone doing "permanent" mask wearing. I've been pretty fastidious about face coverings since early on but I don't think I've ever kept one on for more than 6 hours at a time, and it's hard to imagine anyone doing so outside of a long shift at work.
