I hang damp bath towels to dry in the bedrooms, especially at night. Have even been known to get them nearly dripping wet to hang on a clothes rack at the foot of the bed.
Never dry clothing completely; use a dryer rack to finish hanging them out of the dryer each day, as this adds a hint of moisture to the air.
Use a neti pot to keep your nose moist and clear.
Leave an inch of water in the bottom of the tub, and leave the toilet seat lids up.
