Cold Hands & Feet

It's because you're basically warming the floor, it is similar to how elephants use heat. They got their thick skin which is like our clothes, but through their ears there's a lot of blood flow through which they lose their heat to keep their temperatures a bit lower. Same story pretty much goes for your feet, the blood flowing through it is losing energy in the form of warmth to the colder floor, then in the rest of the body it takes up energy again to warm up and flows towards the feet again where it gives it away. This process keeps going on and on making you lose energy. With your hands and other parts this happens a lot less fast, because air doesn't take up energy as fast as solids, metals are pretty much fastest of all. Heat absorbing properties and such. So unless you're touching something with your hands, you won't lose that much energy due to it relatively speaking compared to your feet. You can increase the loss of energy through your hands by flapping your hands and basically moving the air, but it remains less effective. When you touch something solid though it goes a lot faster just like with your feet. In a similar way though you can also warm up your body quite easily by placing your feet in warm water, energy just going the other way this time.

yep... but we have cement floors which really draw the heat out of my feet. sometimes it is downright painful. my hands tend to get cold when I am typing or playing the violin.

I have the same problem :-( And nothing helps. Even i am with warm clothes, socks and etc. Some think that the reason is lack of enough movement.

Yes, I have this same problem with my cold feet. I can never get my feet to get warm unless I have a fever. lol I guess it doesn't really matter with me as my feet are always cold. I don't really worry about it anymore. :)
