Yes, in some cases, air pollution can result in bronchitis.
Bad air quality resulting from pollutants such as cigarette smoke and traffic emissions has been linked to an increased risk of developing bronchitis.
A 2021 study found that prolonged exposure to harmful gases, such as nitrogen dioxide and black carbon, can cause bronchitis. These gases typically enter the air through burning fossil fuels, which result from activities that require energy from coal and oil, such as:
- running power plant stations to produce electricity
- using gasoline-fueled cars and trucks
- operating large forms of transport, such as ships and airplanes
If you live near a power plant or fuel your vehicle using gasoline, you can be more likely to breathe in harmful gases, increasing your risk of respiratory issues such as asthma, lung cancer, and bronchitis.
The American Lung Association shares the following methods to protect yourself from bad air quality or air pollutants and reduce your chance of developing bronchitis:
- Wear air pollution masks that cover your mouth and nose.
- Carpool or use public transport.
- Limit your time outdoors when possible.
- Close windows and doors when you’re inside.
- Limit outside activities, especially near air pollution sources.
- Use air filters in your home.
- Avoid smoking and secondhand smoke.
Bronchitis typically goes away on its own. However, a healthcare professional may suggest the following to help manage symptoms while you recover:
- getting plenty of rest
- using a humidifier
- staying hydrated
- taking over-the-counter medications, such as cough suppressants
If your symptoms are not going away or getting worse, consider speaking with a doctor. They can help determine if it is a sign of a more serious health condition.
