Eat your fluids to stay hydrated - CNN

If your water bottle travels with you everywhere, sip on this thought: Drinking water isn't the only way to stay hydrated.

Several factors influence your need for water, including climate, muscle mass, physical activity, and diet. (People who have more muscle need more water -- that's why men generally have higher fluid requirements than women.)

Food, often overlooked as a water source, can be a rich supply of fluid. On average, it provides 20 percent of the fluid we need -- and far more if you choose water-rich fare.
