Several years ago, I was real sick. We finally went out & bought a humidifier for the bedroom. It worked wonders. Don't know why we never got one sooner. In the wintertime, the air is so dry. At night, your throat gets dry, so it can make you cough. We even have a little guage that gives the temp. & humidity. It will say if it is dry, comfortable, or wet. They do take some routine maintenance, but they are worth it. Now, I've got to get to bed. I have a cold & should be getting my rest. All the best to everyone! Ruth M. Ross [log in to unmask]
