Sitting at a desk all day, it's not that hard to stay properly hydrated. I drink water before and after exercising in the morning, and then I keep a big glass of water at my desk all day long. I don't monitor exactly how much water I drink -- I'm not a big believer in getting a certain number of servings. Instead, I pay attention to my body and I know when I've had enough.

Probably the best way to gauge your hydration is by the color of your urine. Your urine should be pale yellow or nearly clear. If you find you need to hydrate a little more, but can't imagine drinking any more water, never fear. There are many foods that help you hydrate. Check out the gallery for some ideas. Cooking Light also has recipes incorporating hydrating ingredients.
