Ah, you're describing physiological process of "cold diuresis." It's the
opposite of sweating, where water is evaporated out the skin. In the cold,
blood is shunted away from the periphery (hands, feet, skin, superficial
tissues) and into the central regions of the body, including the kidneys.
When the kidneys get more blood, they produce more urine.

Important to have extra hydration in cold and at altitude.
