I have to wear a mask at work all day in a largely non-climate controlled environment. We have been having regular 90-degree 90% humidity days since the heat wave started and when you're wearing a cloth mask over both your mouth and nose it's practically impossible to breathe properly. Just standing outside for five minutes waiting for the whistle to ring in that heat is pretty much unbearable and I just uncover my nose most of the time when I'm not close to other workers. If you use a dinky little paper mask it's easier to breathe but if you physically exert yourself even slightly you sweat so profusely it ruins the mask in seconds.
