Your home is too dry. For living in a place like Minnesota with your furnace constantly on in mid-winter, that humidity level should be above 55.
Anyone with sensitive skin (there are millions in USA) would be itching and flaking dry skin in your home, without any aid of special moisturizers. My humidity is always above 65. I like it where the windows remain dry, but bordering wetness / fog.
I have terrible sensitive skin - remain indoors for most of the day and all of the night and I'm not itching at all, here in cold Michigan.
