While we constantly hear about how healthy water is for our systems, too much of a good thing is possible. Drinking lots of water in a short period of time, say a few hours, can lead to “water intoxication,” which, although rare, can be quite dangerous if not treated promptly and properly. While our kidneys are capable of processing about 60 glasses of water a day – almost four gallons – most people need nowhere near that much. Instead stick to six to eight 8-ounce glasses per day, more if you are in a very hot, dry climate or participate in endurance sports. A safe amount of water to drink while competing in endurance events is between eight and 16 ounces (1 to 2 glasses) per hour. If you do consume a large amount of water in a short time, be aware of symptoms of water intoxication, such as nausea, vomiting, fatigue and confusion, and seek help immediately.
