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 cases, harmful.

In a study, Dr Stanly Goldfarb and Dr Dan Negoianu, both of the Renal, Electrolyte and Hypertension Division at the University of Pensylvania, 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 back the public opinion that drinking 8 glasses of water every day benefits health. At the same time, they fond little proof of harm in drinking 8 glasses of water every day.

It is widely believed that in some cases-such as athletes, people who live in hot, dry environments, and those 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 increased headaches when their consumption（消耗）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 o small between the two groups as to be considered unimportant.”

The researchers concluded that there is no scientific proof to support that average, healthy people need to drink at least 8 glasses of water each each day.

The website medheadines.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.

Spending a lot of time watching TV, playing video games and surfing the Web causes a lot of healthy problems to children such as overweight and smoking, US researchers said yesterday.

U.S. experts analyzed 173 studies on how media sources influence the physical health of children and adolescents (青少年). The studies, mostly carried out in the United States, largely focused on television, but some looked at video games, films, music, computer and Internet use. Three quarters of them found that increased media viewing was connected with poor health.

The studies offered strong evidence that children who get more media exposure are more likely to become overweight, start smoking and begin earlier sexual activity than those who spend less time in front of a screen, the researchers said. Studies also showed more media exposure is linked to drug and alcohol use and poorer school performance. “We were pretty surprised by the number of studies that showed these negative health results,” said one of the researchers in the report.

For decades, experts have worried about the effect on young viewers of the violence and sexual content in some TV programs, movies and video games. Another issue is that kids are spending time sitting on a couch（长沙发) watching TV or playing computer games when they could be running around outside.

One study found that children who spend more than eight hours watching TV per week at age 3 are more likely to be overweight at 7. And research showed that many US children watch far more. Another study showed TV and other media content can have a deep influence on children’s attitudes and beliefs, particularly among teens. A US study published in November showed that adolescents who watched more programs with sexual themes had a higher risk of becoming pregnant (怀孕的) or causing a pregnancy. Thirteen of 14 studies that evaluated (评估）sexual behavior found a connection between media exposure and earlier sexual behavior, the researchers said.
