Are you drinking enough water?

We all know it is important to stay hydrated, but what exactly does “hydrated” mean? Eight 8-ounce glasses of water a day is a good start, but the Institute of Medicine now recommends that men get a total of 13 cups, and for women they suggest nine. Pregnant women need a little more, and kids a little less. If you’re sweating from heat or exercise, or if you are suffering from an illness that makes you throw up or run a fever, then you should up your intake. Dehydration can result in headaches, mood swings, reduced concentration and fatigue. All fluids count toward your daily dose, and there are plenty of foods that contain water, including watermelon, cucumbers and lettuce. The key is to listen to your body and not wait until you are thirsty to drink up. And pay attention to your pee—it should be the color of lemonade.
