I think it's very unlikely (putting it kindly) that your indoor humidity is anywhere near as high as you think, especially this time of year being in the Great Lakes region. During the summer, in a basement, after a heavy cool rain (when the A/C isn't running), maybe...and if so you should have a dehumidifier running.
IMHO, a properly calibrated hygrometer sounds like a must.
