    Cold is a stress on the body, just as heat would be if we lived in more tropical regions- like Sahara. Most people now stay out of the cold but then they are intermixed more with people and it's easier for germs to spread. Plus it's dryer in the winter so there is less of a protective layer of mucus on your nose.

    Because of the cold weather, of course, the breezy winds can be effective to the nose and can cause cold and cough or flu!

    They stay INSIDE close to other people so it's easier to pass 'bugs' around ...................

    They don't, we just get more snow days.

    Two common theories . 1) people spend more time in doors in closer proximity to each other spreading infection . 2) body temperature ( such as a fever ) plays a role in breeding of infection . even a fraction of a degree drop in body temperature gives the ' bugs ' an advantage they might not have in warmer environments .

    Edit : Some attribute the beginning of ' cold and flu season ' to children returning to school , getting together , sharing and bringing home any variety of viral and bacterial infections .

    Idk but if the way people dress during the winter months is any indication, I'm not surprised. It's November and people are still dressing like it was summer - tee shirts and sandals.
