According to a new study released by the National Institute of Environmental Health Sciences, the health benefits of switching from car driving to bicycling are substantially greater than the risks.
From the Abstract:
For the individuals who shift from car to bicycle, we estimated that beneficial effects of increased physical activity are substantially larger (3 — 14 months gained) than the potential mortality effect of increased inhaled air pollution doses (0.8 — 40 days lost) and the increase in traffic accidents (5 — 9 days lost). Societal benefits are even larger due to a modest reduction in air pollution and greenhouse gas emissions and traffic accidents.
Conclusions: On average, the estimated health benefits of cycling were substantially larger than the risks relative to car driving for individuals shifting mode of transport.
Of course, this is not really news for long time bicyclists, but it’s always good to have yet another confirmation from a reliable source.
