It's winter, it's cold, and the heat is constantly blasting throughout my house. This is making the air very dry and uncomfortable to breathe, particularly at night when I'm trying to sleep.
Are there any decent ways to humidify my bedroom without actually buying a humidifier? The only one I'm really aware of is running the shower with hot water, but I don't want to leave that much water running overnight. Plus, I don't sleep in the bathroom.
