The loss of body heat when in the water
Increasing the surface area in contact with a cooler object, reducing the thickness of insulating materials between the body and the cooler object, and ensuring good thermal conductivity of the materials in contact with the body.
In high temperatures there are several methods of body heat loss. One is metabolic heat loss, which is where the metabolism of the body produces heat which is increased in higher temperatures, this in turn produces heat loss. There is heat exchange which is where body heat is lost when making contact with a cooler object. Also conductive heat exchange allows the body to lose heat as coming cool, like water or air, move around the person. The body also uses radiant heat exchange which is where the blood is sent to the superficial arteries and veins to let off heat. Finally there is evaporative heat loss which is of course when a person sweats and as that sweat evaporates it takes body heat with it, thus in turn cooling the body down.

Vasodilation actually facilitates heat loss, by bringing blood closer to the surface of the body, where the heat can more readily move from the body to the surrounding environment. The body employs vasoconstriction to retain body heat, for the opposite reason. Thus even though vasoconstriction can cause peripheral coldness and pallor, it's only because the body is conserving its heat in an attempt to prevent the core body temperature from dropping.

Oxidation. That is a chemical reaction process that has nothing to do with heat loss.
