"You are what you eat," goes an English saying. But actually, you are what you drink. Why? Because 75% of your body is water! When we don't give our bodies enough water, our organs cannot work properly. We are also easier to catch a disease. When we are sick, drinking plenty of water should be one of the first things we do.
Is your body asking for more water?
If you experience headaches, sleepiness, allergies or dizziness (头昏眼花), your body might be telling you to drink more water.
Even problems such as nervousness or forgetfulness can be caused by lack of water. In addition, the medicines that treat these illnesses can sometimes dry out your body further. The more water you are lacking in, the worse your health will be-no matter how much medicine you take.
How much water is enough for you?
Most experts suggest drinking at least 8-ounce glasses of water every day. However, if you weigh more than 128 pounds, you need even more water. Drink an extra glass of water for every 15 pounds of body weight.
Drink more water in the hot summer months and when you exercise to replenish (补充) the water loss through sweating. Caffeine makes your body lose water very quickly. So drink extra water if you drink beverages such as coffee, tea and soda.
