22:06:00 +07:00 I'm finding that very humid environments make my lungs worse. More coughing. Also air polution. People keep banging on about masks, and seemingly everyone wears them, especially here in HCMC. But imho they don't work!
They don't filter the air very well, because the poluted air just goes around the sides of the mask. So you inhale it anyway. And ontop of that, the air on the inside of the mask is hugely humid, because obviously the air that comes from your body is full of water vapour.
Isn't this mask theatre really just a dangerous way to avoid the air polution problem? #
