I use a Dust Bee Gone mask. It is the only one I have tried to date that doesn't make me fog my glasses (haven't tried the 3M one). I've had it for a while now but I didn't really use it much unless I was sanding.
Then I took a week of vacation a month or so ago. My goal was to spend the time out in the shop and get good and ready for Christmas and the winter birthdays because I can't get out in the shop once the temps get too cold. Now, I've known for a long time that working in the shop dries out my hands like crazy. It never even crossed my mind that it could be drying out other things. I spent Monday in the shop as planned. Tuesday morning, I work up way too early and was going to go back to sleep for another hour or so but realized my sinuses seemed really full. So I grabbed a tissue, blew my nose and ended up with two hands full of blood. Anyway, to shorten this, I ended up at the urgent care in the early afternoon because I couldn't get it to really stop. If you haven't ever had your nose cauterized, consider yourself lucky. Even with that though, it continued to bleed until I ended up in the emergency room where they packed it up. Another not very pleasant experience. Even then the blood was trickling out of both nostrils and wanting to go down my throat. Had to leave the packing in for another 24 hours during which time I couldn't even lie down. After that, I wasn't supposed to bend at the waist or lift anything heavy for "several days." Having just been through all that, I was following instructions. Aside from what I got done on Monday, the rest of the week was a complete loss, scrolling-wise.
Why did it happen? The doctor said it was probably because the inside of my nose got too dry. In hindsight, it was obvious. When I touch it the wood and sawdust, my hands get dry. If I breathe it, in only makes sense that my nose would dry out too. I couldn't tell you the last time I had a nosebleed before this one and I have never had one as relentless as this one. I'm using my mask all the time now. I'm still working on remembering it and getting used to it but I don't resent the inconvenience. Not after that experience. I'm also taking other steps to keep my nose moist - the saline spray and, on woodworking days I also put some petroleum jelly on a q-tip and swab myself. Maybe I am overly paranoid after the experience but I sure don't want to walk down that road again.
