回答题Why Are America's Kids So Stressed
I'm usually fairly skeptical about any research that concludes that people are either happieror unhappier or more or less certain of themselves than they were 50 years ago. While any ofthese statements might be true, they are practically impossible to prove scientifically. Still, Iwas struck by a report which concluded that today's children are significantly more anxious thanchildren in the 1950s. In fact, the analysis showed, normal children ages 9 to 17 exhibit ahigher level of anxiety today than children who were treated for mental illness 50 years ago.
Why are America's kids so stressed? The report cites two main causes: increasing physicalisolation -- brought on by high divorce rates and less involvement in community, among otherthings -- and a growing perception that the world is a more dangerous place.
Given that we can't turn the clock back, adults can still do plenty to help the next generation cope.
At the top of the list is nurturing a better appreciation of the limits of individualism. Nochild is an island. Strengthening social ties helps build communities and protect individualsagainst stress.
To help kids build stronger connections with others, you can pull the plug on TVs andcomputers. Your family will thank you later. They will have more time for face-to-facerelationships, and they will get more sleep.
Limit the amount of virtual violence your children are exposed to. It's not just video games and movies; children see a lot of murder and crime on the local news.
Keep your expectations for your children reasonable. Many highly successful people never attended Harvard or Yale.
Make exercise part of your daily routine. It will help you cope with your own anxieties andprovide a good model for your kids. Sometimes anxiety is unavoidable. But it doesn't have toruin your life.
