久坐的危害可能比你想象的更大

If you work a desk job, you might make up for all that sitting around by going for a run every day after leaving the office. That exercise cancels out the negative effects of eight hours spent in a chair, right?

如果你在辦公室工作，你可能每天離開辦公室后通過跑步來彌補這一天的久坐。運動可以抵消八個小時坐在椅子上的負面影響，可以嗎?

Wrong, according to a new advisory from the American Heart Association.

據美國心臟協(xié)會的一項新報告表明這是錯誤的。

In the lengthy paper, a team of cardiology experts reviewed existing evidence about the link between sitting and health. Their conclusions, published this week in the journal Circulation, say that no amount of physical activity is enough to combat the dangerous health effects of sitting for hours each day.

在這篇冗長的論文中，心臟病專家小組回顧了現有關于久坐與健康之間關系的論證。其結論于本周發(fā)表在《循環(huán)》雜志上，認為再多的體育活動也不足以抵消每天久坐所帶來的健康危害。

The average American sits for six to eight hours per day, according to the AHA’s report. Studies have linked long periods of sitting with an increased risk for diabetes, heart disease and even cancer. Sedentary days have also been shown to increase anxiety.

據美國心臟協(xié)會報告美國人每天坐著的時間平均六到八個小時。研究表明久坐會增加患糖尿病、心臟病、甚至癌癥的風險。還表明其會增加焦慮感。

Some research has found that frequent breaks from sitting - even simply fidgeting! - can help ward off its negative health effects.

一些研究發(fā)現，坐立期間不斷休息―即便只是坐立不安―可以幫助避免其對健康的負面影響。

But those efforts are not enough, the new advisory says, confirming earlier reports. The cure for all our sitting isn’t exercising more. It’s sitting less.

但新報告卻認為這些還不足以證實早些時候的報告。治療久坐的方式的不是更多的運動，而是少坐。

"Regardless of how much physical activity someone gets, prolonged sedentary time could negatively impact the health of your heart and blood vessels," said Dr. Deborah Young, chair of the report, in a statement. "There is evidence to suggest that sedentary behavior could contribute to excess morbidity and mortality."

“不管做多少體育運動，長期久坐都可能會影響心血管健康，有證據表明久坐可能會導致發(fā)病率和死亡率過高，”該報告的主席黛博拉。楊博士在聲明中如是說。

In other words, sitting may kill you faster. And while experts say they don’t have enough data to recommend exact time limits for chair potato-ing, it’s wise to adopt their mantra of "Sit less, move more.“

換句話說，久坐可能很快就會要了你的命。即便專家稱他們還沒有足夠的數據來推薦坐在椅子上的確切時間，但是把“少坐多動”作為口頭禪是明智之舉。

Popular ways to sit less include trading TV time for active hobbies, walking or biking to work instead of riding in a car or bus, or hosting a walking meeting instead of gathering your colleagues in a conference room. Even setting regular alarms on your phone can be a helpful reminder to stand up, stretch, and decrease your sitting time by a few minutes each day. Your body will give you a standing ovation。

比較受歡迎的少坐方式包括：把看電視時間換成積極的愛好，步行或騎自行車上班，而不是乘汽車或公共汽車，或者召開一次步行會議，而不是把你的同事叫到會議室。甚至在手機上設置鬧鐘，提醒你定時站起來伸展一下，每天減少幾分鐘坐著的時間。你的身體將為你起立歡呼。
