Hot air rises, taking large amounts of pollutants skyward. On air inversion days, the clouds prevent the sun’s rays from getting through to the ground, so the air near the ground is not heated, remains colder and doesn’t rise, causing the air with its pollutants to remain close to the ground.

Air pollutants such as carbon monoxide, ozone, carbon dioxide, and sulfur dioxide can damage your lungs. When you exercise . . .
