Walking is good for you... even in the smog
Walking or cycling is good for you even in polluted cities, researchers have found.
研究人员发现,即使在有空气污染的城市,行走或骑车也是对健康有益的.
The health benefit of physical activity outweighs the harm caused by chemicals and dust puffed out by traffic and industry, according to Cambridge academics.
根据剑桥大学学者的研究,体育锻炼对健康的好处要大于汽车和工厂排放的化学物质和灰尘造成的危害.
Air pollution is a major problem in British cities, and is estimated to contribute to 40,000 early deaths in Britain every year.
空气污染是英国城市的主要问题,据估计,英国每年有四万人因空气污染而过早死亡.
People who exercise in polluted areas are thought to put themselves at increased risk, because they take deeper breaths, inhaling more of the toxic pollution and particles that do such damage.
人们通常认为,在污染区域进行体育锻炼会增加患病风险,因为锻炼时呼吸更深,会吸入更多有毒污染物和颗粒物,而这些污染物都对健康有害.
But a new study, published in the journal Preventive Medicine, suggests that the act of exercising outweighs this risk, because physical activity reduces the risk of diseases such as diabetes, heart disease, and several cancers.
但是,一项发表在《预防医学》期刊上的最新研究表明,锻炼带来的益处远甚于它带来的风险,因为体育活动可降低患糖尿病、心脏病和某些癌症的风险.
Experts at the Centre for Diet and Activity Research - a collaboration between the universities of Cambridge and East Anglia - used computer simulations to compare the risks and benefits of exercising in polluted areas around the world.
