Lately, I have been briskly walking the 5K route at my workplace with some friends. It is cold out, or at least what passes for cold in Tennessee. Let's say it's 40 F (roughly 5 C) or colder outside.
As I walk briskly, my hands get very hot. As my friends walk briskly, their hands remain cold. In fact, they have to wear gloves on the walk because their hands are so cold. When we get back to our office, my hands are extra warm and puffy, and theirs are cold. We are all sweating in our torso regions and breathing somewhat heavily from the exertion, so it's not like I'm the only one who has exerted him/herself. They think I'm a freak because my hands are so hot and swollen. I think they're freaks because their hands are so cold.
Question: What happens to your hands when you walk briskly on a cold day?
