For better or worse, we have an old drafty house so that helps! If you need to get your humidity down, exhaust fans in the kitchen and bathroom and laundry room help --all fans should vent to the outside (not attic). Your attic and basement and crawl spaces need to be ventilated too. And you can get a dehumidifier.
