I have the same problem you do but with mine they're surfaced so rubbing my nose will make them bleed. Dry heat will do it as well.
I do, but we're on well water and the type of humidifier we have evaporates a salted mist into the air making the issue worse.
And since my office is cold in the winter I have to decide between a personal heater or freeze my ahem off.
They don't happen often, only when I'm stressed a lot, ill, or hot. But they have happened in ice cold weather too. So it really don't matter.
