Drinking water / hydration

[CDAT]

One thing to keep in mine with water through the stomach the human body can only absorb about one to one and a half quarts of water an hour. Any more than this and you just pee it out and also run the risk of water intoxication.

Which is why one should not be allowed to guzzle a tummyful of water, but swish each sip/mouthful around to allow the mucous membranes to get their share. It is also more psychologically satisfying than gulping, despite the tendency of a desperately thirsty person to do so.
Another issue that makes a stomachful of water counterproductive is the possibility of vomiting up the excess, thereby wasting the water and further dehydrating yourself. At least peeing it out keeps one's kidneys in function and staves off damaging them.
