I've heard conflicting answers as to which water absorbs faster in bloodstream. When you drink water, which water absorbs into your bloodstream faster, lukewarm water or cold water? More times than not I hear it is cold water, but why? I would think it would be lukewarm, and if so, can anybody post why? Thanks.

The water doesn't go straight into the bloodstream. It will go into your stomach just like the rest of your food and enters the bloodstream in the first few segments of the small intestine. By that time, the water is at body temp - it has absorbed the heat from your body. The nice part about that is that your core body heat has radiated to the water. You still have the same amount of heat, but it has dissipated to the water and you will lose that water sooner or later due to sweat.
From a chemistry standpoint, warmer molecules are more chemically active than colder ones. They move faster. If the temperature of the water at the absorption point (small intestine) is cooler than body temp, it would diffuse into the bloodstream more slowly than water at body temp.

By the time liquid reaches your stomach to be absorbed, it's all about the same temperature.
You get more relief from the heat by drinking cold water because it does lower your 'core temperature` as your body warms it up.
