The rising rates of asthma are a growing concern in the United States. This chronic respiratory condition is exacerbated by factors such as air pollution, allergens, and temperature fluctuations, making the choice of living environment crucial for those who suffer from it. This article lists five U.S. cities that have been identified as the most challenging for individuals with asthma, based on the American Lung Association's "State of the Air" report and Asthma and Allergy Foundation of America's "Asthma Capitals" report.

Fresno, California

Fresno, California is one of the worst cities for asthmatics due to its high levels of air pollution. The city's geographical location in the San Joaquin Valley traps pollutants, leading to poor air quality. Additionally, the city experiences high levels of pollen, another trigger for asthma attacks. These factors combined make Fresno a challenging place for asthmatics to live.

Bakersfield, California

Bakersfield, another California city, is known for its high levels of particulate pollution. The city's increased industrial activities and heavy vehicular traffic contribute to the poor air quality. This, along with the city's hot and dry climate, exacerbates respiratory problems, making it a difficult place for people with asthma.

Pittsburgh, Pennsylvania

Although the East Coast generally has better air quality than the West Coast, Pittsburgh in Pennsylvania is an exception. The city's industrial history and topography contribute to high levels of both ozone and particulate pollution. The cold winters also pose a challenge as cold air can trigger asthma symptoms.

St. Louis, Missouri

St. Louis, Missouri is a challenging city for asthmatics due to its high levels of both ozone and particulate matter pollution. The city's location in the Midwest, with its hot summers and cold winters, can lead to extreme temperature fluctuations, a known trigger for asthma symptoms.

Cleveland, Ohio

Cleveland, Ohio rounds off the list of the worst cities for people with asthma. High pollution levels, due in part to the city's industrial activities, make the air quality poor. Additionally, Cleveland's cold and long winters can be particularly harsh for asthmatics.
