Air pollution: Benefits of cycling and walking outweigh harms - study

(BBC News, 5 May 2016) The health benefits of cycling and walking outweigh the harmful effects of air pollution, a study has suggested.

Air pollution contributes to 40,000 early deaths each year in the UK and we gulp in more of it when we exercise.

On the other hand, regular exercise reduces the risk of diabetes, heart disease, and several cancers.

The University of Cambridge study showed that even in cities with high pollution levels, the benefits outweigh the risks.

The researchers used computer simulations to compare data on different kinds of physical activity and different levels of air pollution in locations around the world.
