I always understood it as your immune system gets weaker from being in the cold and makes it easier for viruses and such to propogate in your body. We're constantly fighting off minor infections and disease, and thankfully our immune systems are pretty strong....cold does not help it.

I'd say this one is sort of true...in the right context.

My wife likes to say that so she can keep believing that you can catch a "cold."

No cold virus. No cold.

I thought the opposite. That when you're cold, and your body releases Norepinephrine, that it re-enforces your immune system.

Which makes sense to me from a personal experience. I like to run around in the snow in tshirt and shorts and embrace the cold. I very rarely catch colds and always thought it was genetics and not a product of environment
