- Water: "Having a glass of water before you go to bed helps your body replenish the fluids it loses throughout the day from normal activity. Since your body is mostly water, you need to keep it hydrated in order for it to work properly. Because you are not working as hard while you sleep, your body doesn't need to excrete as many fluids. When you provide it with water before you to go bed, it simply refills its necessary levels." (http://www.fitday.com)
