Dry air makes your mucus membranes much more virus hospitable.

35 years ago an allergist told me that and said to run a steam vaporizer ANY time the heat was running. We followed that advice and our winter colds decreased by at least 50%.

I have one running right now. I am experiencing my first winter cold this season.

I absolutely agree....plus the vapor retains the heat in your home. I’ve always had a vaporizer running or a kettle going. And also found far less winter illnesses doing so. No flu or colds this winter at all. Now if I could find the magic bullet for Allergies!

Good advice generally. In this case, it is also theorized that it causes the droplets/virus to clump and fall to the ground where they are much less likely to infect someone - especially through inhalation.
