Yes. The fine dust gets everywhere. Imagine rolling around in the sand at the beach, but 10x worse. Skiing, what, you turn the corner of the mountain and there's a snow maker running full bore at you so you're a little bit cold but then the snow melts into water when you do get inside. You're all suited up but it's okay because it's cold outside. You could wear a tyvek suit to do drywall, but then you're sweating too much to do the job.
