Is bottled water better for you than tap? Or should you choose vitamin-enriched water? Experts say, skip it all.None of these products is likely to make you any healthier.Below, we look at four major myths about the benefits of drinking water. 1 Experts say there’s an easy way to judge.If you are not thirsty, your fluid intake is likely “just right”
Myth No 1:Drink eight glasses each day.
Scientists say there’s no clear health benefit of drinking so much water a day. 2 “Nobody really knows,” says Dr.Stanley Goldfarb, a kidney expert at the University of Pennsylvania.
Myth No.2:Lots of water equals healthier skin.
The body is already 60 percent water. 3 Adding a few extra glasses of water each day has a limited effect.“It’s such a tiny part of what’s in the body,” says Goldfarb.“ It’s very unlikely that one’s getting any benefit.”
Myth No.3: 4
A more accurate statement may be:Drinking water is a helpful tool for dieters.“Water is a great strategy for dieters because it has no calories,” says Madeline Fernstrom of the University of Pittsburgh.“So you can keep your mouth busy without food and get a sense of satisfaction.” But water is not magical, she adds.“Other zero-calorie options such as diet sodas are fine, too.”
Myth No.4:It’s easy to get dehydrated(脱水的)during a workout.
Dehydration sets in when a person has lost 2 percent of his or her body weight. 5 “It’s also obvious that individuals in hot, dry climates have an increased need for water,” says Goldfarb.“But for a walk in the park, no water bottle is necessary.”
A.So where does the standard advice come from?
B.But it’s unclear whether these changes are clinically significant.
C.So for a 200-pound man, this means losing 4 pounds of water.
D.Drinking extra water leads to weight loss.
E.Drink as much water as you can.
F.So, if you take a 200-pound man, he’s 120 pounds of water.
G.But first, how do you know if you’re drinking enough water?

A new study suggests that the more teenagers watch television, the more likely they are to develop depression as young adults .
The researchers used a national long-term survey of adolescent(青少年的)health to investigate (调查)the relationship between media use and depression. They based their findings on more than four thousand adolescents who were not depressed when the survey began in 2000.
As part of the survey, the young people were asked how many hours of television or videos they watched daily. They were also asked how often they played computer games and listened to the radio. Media use totaled an average of five and one-half hours a day. More than two hours of that was spent watching TV.
Seven years later, in 2007, more than seven percent of the young people had signs of depression. The average age at that time was twenty-one.
The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio, etc. But the study did find that every extra hour of television meant an eight percent increase in the chances of developing signs of depression. Young men were more likely than young women to develop depression given the same amount of media use.
The study didn't explore if watching TV causes depression. But one possibility is that it was taking time away from activities that could help prevent depression.
Last December, the journal Social Indicators Research published a study of activities that help lead to happy lives. Sociologists from the University of Maryland found that people who describe themselves as happy spend less time watching television than unhappy people. The study found that happy people are more likely to be socially active, to read, to attend religious services and to vote.
