Why we feel cold

Playing outside with my kids today, I was marveling at the fact that the cold doesn't seem to bother them. As they threw themselves down the mini-snow mountain in our front yard again and again, they seem oblivious to the fact that it's only 20 degrees out there. I, on the other hand, was shivering in my boots!

Every wonder why we feel cold? Scientists have narrowed the sensation down, mostly, to a single protein called TRPM8, though they believe that there are really two neurons that transmit cold -- one that gives you that pleasantly cool feeling and another that makes you feel cold-pain.

If you're like me, though, you don't really care about the scientific reason why you're cold...you just want to warm up. Time to double up on those socks and dig out cute winter hats and mittens!
