So I just ran across this hydration calculator. It makes you put in your weight, asks how long you exercise, and a few other questions and it tells you how much water you should drink a day! I thought it was pretty cool. It seems to be a more exact answer than just the basic 8 glasses a day...because really glasses come in all shapes and sizes so how much is really a "glass"?
My results were: "138.5 ounces of water today, or 4.2 liters.
If you eat a healthy diet, about 20 percent of your water may come from the foods you eat. If you eat a healthy diet you can drink 110.8 ounces of water today, or 3.3 liters." Thats like WAY more than Ive been drinking! I need to get on the ball!
Check yours out at, nutrition.about.com/library/blwatercalculator.htm , if youre interested! =)
Sorry, its late and I cant sleep and Im a bit rambly! lol
