The skin, including the skin on your hands, has thermoreceptors that send messages to the brain about temperature. However, they respond to CHANGES in temperature, not temperature itself. So, if you come in from the cold, all surface temperatures will feel very warm, but gradually as you warm up, the surfaces will seem neutral. And, think about what happens when you put your hand in a lake on a hot day - it feels really cold, but if you jump in, eventually your skin will adjust to the temperature. Now, if the surface is burning hot or freezing cold, the pain receptors, not the thermoreceptors, in your skin react.
