①You know that whole thing about drinking eight glasses of water a day? Sorry to have to tell you this, but it may not do you as much good as you think. It won't make your skin brighter. It won't make you feel more clear headed. It won't make you more energetic. It will, however, make you have to pee(小便) a lot. After all, your body can't take that much water, so it needs a way to get out.
②Most of the time, your body will tell you when you need to drink water, because you have these wonderful, amazing, undervalued things—kidneys (肾). Every day, the blood(血液) in your body passes through the kidneys. What you eat and drink, the temperature around you, and how much you exercise—all of these do something to your body. Your kidneys, with your nervous system(神经系统) and different kinds of hormones (荷尔蒙), care about what your body needs and keep the balance of your body.
③For example, after exercising for a long time, you may sweat （出汗）a lot, so you're losing water from your blood. The kidneys know your blood volume (容量) is going down and the blood is getting saltier （含盐量更高）. They want more water back into the blood to keep the balance. So they will give you a sign to drink, which means you will get thirsty. If you don't have enough water, the thirst message will get stronger and stronger.
④A lot of people may say that they don't drink much water, but here's a point that's often missed: there is water in every single thing you put in your mouth. Your morning milk has water, so does your breakfast. And that snack—an apple, an orange, or a glass of juice, just like you, is made of water too.
