Will have a look! The fact that our mucous membranes dry out is caused by the dry heating air in the rooms, not the cold weather. I made my point no clearly there. I wanted to point out that the cold is caused by viruses and that cold weather is in favour for influenca to spread since our immune system is weaker. Without germs there is no infection, doesn't matter how cold it is. Hope you can agreee on this

Sure that is a good point to make. The old wives tail that if you get cold you'll catch a cold, is true. Not for the reasoning exactly that mother's and grandmother's thought, and perhaps not due to anything that bundling up in a coat and hat can help with. The cold disrupts the functioning of interferon in our nasal pathways, our first line of defense against viral Invaders.
