lose water through urination (排尿), respiration ( 呼吸 ), and by sweating. If you are very active, you lose more water than if you do not take much exercise.

3.A good rule of thumb (好的做法) is to take your body weight in pounds and divide that number in half. That gives you the number of ounces (盎司) of water per day that you need.
