Without water, your body would stop working properly. Water makes up more than half of your body weight, and a person can’t survive for more than a few days without it. Why? Your body has lots of important jobs and it needs water to do many of them. For instance, your blood, which contains a lot of water, carries oxygen to all the cells of your body. Without oxygen, those tiny cells would die and your body would stop working.

Most people think they can get water only from drinking water. However, they can get enough liquid through the drinks they consume every day. These include water, fruit juice, coffee, soda, iced tea, and other drinks. Your body doesn’t get water only from drinking water. Any liquid you drink contains water. Lots of foods contain water, too. Fruit contains quite a bit of water, which you could probably tell if you’ve ever eaten a peach or a plum and felt the juice dripping down your chin! Vegetables, also, contain a lot of water.

How much water should people drink? Many people believe they are supposed to drink eight glasses of water a day, or about two liters. Why? Because that is what they have been told all their life. But a new report offers some different advice. Experts say people should obey their bodies; they should drink as much water as they feel like drinking. The report says most people meet their daily needs for liquid by letting thirst be their guide.

You lose water when you breathe, sweat and so on. So you need to supplement (补充) enough liquid to stay healthy. If you don’t get enough water, you could become dehydrated (脱水). If you get very dehydrated, your body will no longer have enough liquid to circulate. This is very dangerous. Dehydration also can keep you from being as fast and sharp as you’d like to be. Serious dehydration can even make you sick.
