A new study of more than 50,000 Danish adults suggest that I might be ok. Of course being Denmark, more than 2/3 of them regularly rode a bike and half played sports. As you might expect, both activities lowered the Danes’(丹麦人) risks of death during a 17 years study period. But that effects held true even for Danes exercises in the most polluted parts of Copenhagen, suggesting that the short-term heavy intake of pollutants during exercise is just small proportion of their overall exposure to pollution and thus, does not diminish the benefits of exercises. The results are in the journal Environmental Health Perspectives. 

  Of course Copenhagen has pretty clear air, even by European standards. So these results might not translate to, say, Beijing. And researcher still advise exercises in green spaces, parks and other road free areas if possible. But hey! I’d had to head all the way to midtown Manhattan for that. “Central Park, central park, who cares about central park..”
