Why will you have a greater reaction to having cold water

Why will you have a greater reaction to having cold water poured all over your back compared to just a few drops of cold water on your arm? Pouring water stimulates more sensory neurons than a few drops of water. Cold water on the back stimulates a heightened response because it is further away from normal body temperature. More sensory neurons exist in your arms than in your back because the arms are exposed more to the environment. Cold water poured down your back will initiate a sympathetic response and, therefore, all reactions will be greater.
