When I was a kid I'd get pretty bad nosebleeds every winter, due to dry air and having difficulty keeping my nose clear. This pretty much stopped when I moved to more humid climates.
But this winter has been pretty dry indoors, and now I'm on blood thinners...
@fluffy I used to have an aquarium as a kid to keep the humidity in my room up. These days I have gotten a couple of wicking humidifiers that work pretty well. (Thinking about investing in a whole-house humidifier at some point. )
