According to the U.S. Environmental Protection Agency (EPA), air pollution can trigger heart attacks, strokes and worsen heart disease.

People with heart disease should check the daily Air Quality Index (AQI) forecast, which is color-coded. Code orange or higher represents a condition that can be harmful to your heart.

On bad air quality days, it is best to reschedule outdoor exercise or exercise indoors instead, and avoid exercising near busy roads.
