It's a little like swimming, you don't breathe under water either.
I will tell you this, the dust is dangerous, in great quantities it can hurt you, and even kill you.
No, I am not joking, breathing in great quantities of any foreign substance can hurt you bad.
I breathe up-wind.
Don't breathe inside clouds of dust.
Don't get inside the clouds in the first place, learn how it works, then learn to time it.
Took a while but it's been years since I've had trouble with the dust.
