rectal temp will decrease (decrease general body temperature bcoz of the cold water) skin blood flow decrease (reactive vasoconstriction, to conserve heat)

I agree that rectal temperature will decrease.

However, I was thinking that maybe over-hydration could cause more blood volume and thus increased blood flow to the skin?
