Water Intoxication "You would need to chug down about three quarts of water or more all at once to come down with a case of true water intoxication. It does happen, but so rarely that I couldn't find statistics on the number of cases. These people become drowsy, lightheaded, and weak. They have trouble coordinating bodily movements and thinking straight, looking and feeling as if they just stumbled out of the local bar. But the water-intoxicated can't just go home and sleep it off. They must get treatment or risk going into convulsions, a coma, or even death. What most Americans actually need to worry about is getting the eight glasses of water nutrition experts recommend (that's eight 8-ounce glasses). They suggest even more for athletes or people living in hot climates. While it may seem like a lot, it really isn't when you recognize that water accounts for up to 80% of your body weight and plays an integral role throughout in the smooth functioning of your body's vital systems."
