Propane, body heat, vapor, cooking all end up in the air as moisture.
Get a few of the new damp rid hanging bags. We put one in the kitchen, one in the bathroom, and one in the bedroom. In less than a day they all had 1" of water collected.
If you shower, get a damp rid tub and leave it in the shower stall when yor're finished. Wipe down the shower after each use with a towel. Also wipe the inside of the windows of moisture with a towel each morning, then hang all wet rags, towels, etc outside during the day to dry.
