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?
The link between environment and poverty is central to that great race for sustainability. It is a pity, then, that several powerful fallacies (谬论) keep getting in the way of sensible debate. One popular myth is that trade and economic growth make poor countries' environmental problems worse: Growth, it is said, brings with it urbanization, higher energy consumption and industrialization —all factors that contribute to pollution and pose health risks.
Another common view is that poor countries should pollute now and clean up later. Certainly poor countries should not be made to adopt American or European environmental standards. But there is evidence to suggest that poor countries can and should try to tackle some environmental problems now, rather than wait till they have become richer.
One powerful—and until recently ignored—weapon in the fight for a better environment is local people. Much academic research has shown that the poor are often victims of resource depletion (损耗) : it tends to be rich locals or outsiders who are responsible for the worst exploitation (开发). Local people usually have a better knowledge of local ecological conditions than experts in faraway capitals, as well as a direct interest in improving the quality of life in their village.
