Pollution cancels out benefits of exercise
Green neighbourhoods where people walk and cycle are not as healthy as people think, warn researchers
Living in a green, walkable neighbourhood is seen as highly desirable — but there are caveats to the health benefits, researchers say.
Exposure to air pollution needs to be considered when considering the cardiovascular benefits of walking and cycling compared with driving, they note.
In highly walkable areas, where residents tended to be more physically active, the rates of obesity, hypertension and diabetes were lowest.
