Drinking a lot of water does not do any good to the body, according to two experts in the United States. In fact, they warn, drinking too much water could be, in certain Cas, harmful. In a study, Dr Stanly Goldfarb and Dr Dan Negoianu, both of the Renal, Electrolyte and Hypertension Division at the University of Pennsylvania, the United States, have denied the popular belief that drinking a lot of water clears body toxins (毒素) better, improves skin, and helps reduce weight.Dr Goldfarb and Dr Negoianu say that they found little proof to support the public opinion that drinking 8 glass of water every day benefits health. At the same time, they found little proof of harm in drinking 8 glass of water every day.It is widely believed that in some cas — such as athletes, people who live in hot, dry  environments, and tho with certain medical conditions — drinking a lot of water indeed helps,  but no studies have been done to prove the benefits of this practice in average, healthy people, the  website medheadlines. com reports.The study at the University of Pennsylvania also examined reports that some people experienced incread headaches when their consumption of water was low. In one small study, which the doctors reviewed, the group drinking the most water reported fewer headaches than the control group, “but the difference in the number of headaches was so small between the two groups as to be considered unimportant.”The rearchers concluded that there is no scientific proof to support that average, healthy people need to drink at least 8 glass of water each day.The website medheadlines. com says that, according to an Indian doctor, drinking too much water is harmful. If water enters the body more quickly than it can be removed, problems can occur.1. What’s the key message delivered in the passage? A. Drinking too much water might bring harm. B.
