Hydration Benefits for Runners

I ran across this in a couple of places, so I can’t reliably quote it, but I thought it was worth repeating here if your goal is not only to run faster, but to be a little healthier along the way.
WATER - 75% of Americans are chronically dehydrated. (Likely applies to half world pop.)

1. In 37% of Americans, the thirst mechanism is so weak that it is often mistaken for hunger.
2. Even MILD dehydration will slow down one?s metabolism as much as 3%.
3. One glass of water shut down midnight hunger pangs for almost 100% of the dieters studied in a U-Washington study.
4. Lack of water, the #1 trigger of daytime fatigue.
5. Preliminary research indicates that 8-10 glasses of water a day could significantly ease back and joint pain for up to 80% of sufferers.
6. A mere 2% drop in body water can trigger fuzzy short-term memory, trouble with basic math, and difficulty focusing on the computer screen or on a printed page.
7. Drinking 5 glasses of water daily decreases the risk of colon cancer by 45%, plus it can slash the risk of breast cancer by 79%, and one is 50% less likely to develop bladder cancer.
   Are you drinking the amount of water you should every day?
