Air Pollution Connection, Impact, and Real-world Examples on Asthma
In many parts of the country, local weather forecasts often caution the public about high levels of air pollution. This concern is not unfounded, as extreme weather and sudden changes can irritate the airways, triggering asthma symptoms.
Air pollution, a pervasive issue, has various sources, both indoors and outdoors. Indoor pollutants include tobacco products, building materials and furnishings, personal care and hobby products, household cleaning products, excess moisture, outdoor pollution, and radon. The American Lung Association advises people to take precautions against these pollutants to minimize the risk of asthma development and exacerbation.
The connection between air pollution and asthma is rooted in oxidative stress, a condition caused by the presence of reactive oxygen species (ROS) in the body. These ROS, found in pollutants like ozone (O₃) and fine particulate matter (PM2.5), can overwhelm the airway's antioxidant defenses, leading to oxidative damage to the airway epithelial lining. This damage impairs the epithelial barrier, making the airways more susceptible to allergens, pathogens, and further irritants, which triggers inflammatory responses characteristic of asthma.
Oxidative stress activates inflammatory pathways, such as NF-κB, increasing the production of cytokines like IL-33 and IL-8. IL-8 stimulates neutrophil recruitment and airway smooth muscle contraction, causing bronchoconstriction—a key event in asthma exacerbations. Persistent oxidative stress also drives structural airway changes known as airway remodeling, involving epithelial abnormalities, fibroblast proliferation, and smooth muscle hypertrophy, which lead to irreversible airflow limitation and more severe asthma.
Moreover, oxidative stress induced by air pollution impairs host defense mechanisms, increasing vulnerability to respiratory infections that can further worsen asthma symptoms and trigger exacerbations.
To monitor air pollution levels, the United States Environmental Protection Agency (EPA) uses the Air Quality Index (AQI). People with asthma should be particularly mindful of AQI levels, as levels of 101 or higher are considered dangerous. If experiencing symptoms such as feeling faint, weak, or dizzy, finding it challenging to perform usual routines, a persistent cough, wheezing, or difficulty breathing, even after taking medications, it is essential to contact a healthcare professional immediately.
In response to high AQI levels, states and cities across the U.S. may declare Action Days. For up-to-date information on the quality of the air where you live, visit AirNow.gov. To further minimise exposure to air pollution, people with asthma can speak with their healthcare professional about the possibility of increasing their medication when air pollution is high. By taking these precautions and staying informed, people with asthma can better manage their condition and maintain their health.
