While some disorders have issues in high humidity the minimum suggested for human health in normal conditions is about 35-45% to avoid irritating the respiratory tract and being more sensitive to colds and flus. Getting an entire room to 60% is the controversial point where you start to risk mold growth, you need to be more careful to sterilize your humidifier, and increasing respiratory problems from the other extreme. I ran into major breathing problems and sore throat this past winter so we were checking what we should get the humidity up to for ourselves. At 15% the lack of moisture actually damages wood and can make other items brittle so they are more easily damaged.
