My hands are cold when it's warm inside, i don't feel it at all i feel fine but when i touch someone they jump up telling me i'm freezing!

Vasospasm: Many people have cold hands. This does not necessarily mean there is a problem. Vasospasm of the arteries to the hands can cause cool hands, but if you don't have any pain or discomfort in your hands then don't worry about it. You can try to keep your hands warmer by wearing fingerless gloves and using pocket warmers.. If it becomes painful in any way, get it checked out.
