I'm in New England and while in the summer we often have extreme humidity, in the winter the air is very dry. Especially indoors, heated with forced hot air heating system. Humidity is often 18-20%. That is when static electricity builds up on you while you walk, or even just move your extremities, so you get zapped whenever you touch any metal objects. Some of those zaps are quite painful. And yes, I sometimes get a nosebleed for the sinuses drying out. But we survive. And the low-humidity environment is great for airbrushing and resin casting.
