Granted, I live in a coastal environment, but my household humidity levels fluctuate between 55% and 72% every day. It usually averages around 62%. It's never affected any of us negatively. Actually, if it gets too dry in the house all of our allergies go crazy, and my eczema flares up. I think 62% is perfect. Our humidity outside here is usually pretty high though. Currently it's at 89%, clear skies, no chance of rain. So, I guess we're just used to it?
I do see that you live in New York. It may be a little too cool to support those humidity levels.
