Answer 2

Cold water is not as good for hydration as room temperature. The theory is that the cold water causes the blood vessels surrounding stomach to shrink, slowing absorption.

One theory, upon which medical researchers have varying opinions regards whether drinking cold water is as good for you as drinking tepid water, particularly when you are exercising. Some doctors suggest that room temperature or body temperature water is better than cold water, because the body has to expend energy to heat cold water to body temperature, resulting in some water loss. On the other hand, some doctors say that after physical exertion, you should drink cold water since it will help cool the body more effectively than room temperature water.
