Long-term exposure to dirty air -- specifically, the tiny specks known as fine-particulate air pollution -- shortens lives and contributes to cardiovascular and lung disease. Particulate matter is inhaled almost like a gas and is thought to hike blood pressure, heart attack risk, and the chance of heart disease-related death.

The American Heart Association and the American College of Cardiology recommends that heart patients avoid driving for two to three weeks after leaving the hospital to avoid pollution (and stress). Other research has suggested that a nonsmoker living in a polluted city has about the same risk of dying of heart disease as a former smoker.
