Thank you. The real myth is the idea that it's a myth cold weather doesn't cause colds.

Cold, drier air in contact with your mucus membranes lowers your defenses against viruses. It's that basic. In just regular cold air -- not hypothermia.

Thank you! It always was astounding to me how people could argue with so much vigor and conviction that something as complicated as the immune system could not possibly be affected by something as basic as temperature changes.
