Since the nerves in the skin does not recognize the absolute temperature, like a thermometer. Rather, recognize temperature differences, ie the difference in the temperature of the body and touch everything.
Of course, keep the heat flow from a warmer environment to a cool place. If you absorb your right hand into a bowl, the hand of the heat from the water, so it is warmer than usual. Also takes the basin with cold B heat from his left hand. Therefore, in the Pool C of the nerves in his left hand to say that the water is warmer and the right hand, says its colder.
The skin is the detection of temperature changes.
I do not remember exactly 100%, but I remember learning in school to do something, like the nerves in our body has to work. The man, whom I really want to remember now.
Nerves are adapted to waters in ponds A and B, so that the water in the Pool C looks like a hot and cold hand to another.
Heat flow from hot to cold.
His left hand was in a pool which was warmer than the pool C. When your left hand in the pool C, your hand is warmer than the pool C. The flow of heat from the hand to be cold
His right hand was in part B of the watershed, which was colder than the pool C. Heat flows from a pool of B. If it is your right hand against the pool C, which is warmer, the heat flow from the pool C on the right side . Therefore, you feel hot.
