Answer 1

The Cold also has a numbing effect. When they warm back up the blood vessels expand causing them to warm up quickly. You don’t feel temperature, you feel a change in temperature. So you don’t really feel how cold your hands are, they quickly regain feeling, and you have a large difference in temperature. Its not that different from when you first step into a show and the water feels too hot until you get used to it
