It's healthy rather then dry air. A lot less sinus related problems in the winter
Scott, or should we just say James, James Bond. I like my substrate stirred not shaken. Very cute. Good stuff.
Your points on the humidifier are valid about removing moisture and adding heat in a cold enviroment. I use a humidifier in my CPAP machine when I sleep. It adds moisture to dry air. With the many tanks in my home and their associated heat, I use my central AC unit during winters in the Texas Hill Country.
