Water-way to have a good time

I was reading the New York Time earlier and spotted an article about debunking health myths. The full article is here. The most interesting - about drinking water - is reproduced below.

DRINK EIGHT GLASSES OF WATER A DAY

I had long believed that eight glasses of plain water or caffeine-free beverages a day were important to keep the body hydrated and to prevent constipation. Perhaps the toilet paper manufacturers were behind this notion. Researchers have been unable to find scientific support for it.

The Institute of Medicine recently noted that you can meet your body’s need for liquids in many ways, including drinking coffee and tea (with or without caffeine) and eating fruits and vegetables with a high water content. Two clues that you may need to drink more are thirst and the color of your urine, which should be clear like, well, water.

If you are physically very active, especially in hot weather, repeatedly sipping cold water is helpful. But beyond two quarts, you may need to also replace the salts lost in sweat — for example, by drinking a diluted sports drink or eating foods with salt and potassium.
