There are ways to enjoy exercise in the city while minimizing our risk of cardiovascular damage.
- First, you can assess the amount of pollution in your area with Google Earth's 3D air pollution map overlay.
- Second, try exercising during early morning hours or later in the evening, after most of the work commuters have disappeared from roads.
- Work out during or just after a heavy fog. Experts say that fogs help to clean the air.
- On really hot summer days, opt for indoor climates, preferably ones with air conditioning, or wait until the sun has set to exert yourself out of doors.
