Breathing dirty air is harmful to your health, whether it’s microscopic particulates in wildfire smoke or long-term irritants like ground-level ozone and carbon monoxide from vehicles. However, there’s no denying the benefits of exercise, and a recent study published in the Canadian Medical Association Journal suggests that the advantages of working out, even in less-than-ideal air, may eventually outweigh the negative effects of breathing polluted air. The relationship between the two components is key: heavy exercisers lived longer in polluted areas than sedentary people and even moderate exercisers in the cleanest areas. Pollution clearly lost out to exercise.
