第1936期:Fewer than 5,000 steps a day enough to boost health

For years, thousands of us have been pounding the pavements, trying to reach that magic goal of 10,000 steps a day to stay fit and healthy, but new research has found that walking just half of that could also save lives.

多年来，成千上万的人不停地奔走，试图达到 “每天一万步” 这个被视为有奇妙功效的目标，从而保持身体健康，但一项新的研究发现，每天走路的步数只要达到这个数字的一半就有益于生命健康。

Researchers from the Medical University of Lodz in Poland and John Hopkins University School of Medicine in the US followed 227,000 people for seven years to complete their study.

为完成研究，波兰罗兹医科大学和美国约翰霍普金斯大学医学院的研究人员们对22.7万人进行了为期七年的跟踪调查。

What they found was that walking at least 2,300 steps a day was really good for the heart and blood vessels, and the more people walked, the more they reduced the risk of dying from cardiovascular disease.

他们发现，每天至少走2300步对心脏和血管都有很大的好处，而且走得越多，死于心血管疾病的风险就越低。

And every 1,000 steps above the 4,000 steps mark, brings down the risk of dying early by 15%.

调查还显示，当达到4000步的指标后，每多走1000步，过早死亡的风险就降低15%。
