Ozone pollution, more popularly known as smog, is a big problem. Smog can inflame and damage the lining of the lungs, which can lead to swelling and restricted airways. Inhaling smog is like getting a sunburn on your lungs. This inflammation can lead to shortness of breath, wheezing, coughing and chest pain. It can also aggravate asthma and bring on attacks.
According to the American Heart Association, chronic exposure to air pollution has been linked to heart disease and stroke. The EPA says that exposure to smog can also affect your immune system's ability to fight off bacterial infections.
High levels of ozone, the main ingredient in smog, can cause irritation to the eyes, nose and throat, even in the average person. Bad levels of ozone are formed when heat and sunlight warm certain pollutants from cars and smokestacks from buildings.
Since summer is coming up, it's something we really need to watch out for. If you exercise outdoors in a place that's heavily smoggy, you may notice that it's more difficult to catch your breath. So on high alert days, you may want to workout inside.
