Lysette, Use the humidifier for your sinuses. As soon as the heat goes on, so does the humidifier in my bedroom. Clean out well before you start each year. I still get sinus infections. When I do I get some Echinacea (with Eyebright in it) tincture from the health food store and take it. Works for me.Gail in MD beynong@aol.com http://members.aol.com/beynong/
