Asthma affects approximately 26.5 million people in the United States. While triggers can differ from person to person, poor air quality is a common factor that exacerbates symptoms. High pollution levels increase the presence of irritants, making it harder to breathe.

Additionally, limited access to proper healthcare and asthma treatments can make managing the condition more challenging. Based on data from the Asthma and Allergy Foundation of America (AAFA), several cities are notably difficult for those with asthma. Here's a look at the five worst cities to live in if you suffer from asthma.

1. Detroit, Michigan

Detroit ranks as the worst city for asthma sufferers. The American Lung Association reports the city struggles with low air quality, particularly due to high ozone levels and significant particle pollution. The city's industrial base and heavy traffic contribute to poor air conditions. Unfortunately, these environmental factors worsen asthma symptoms. Detroit also faces higher-than-average asthma cases and deaths, ranking third in asthma cases and eighth in asthma-related fatalities. Combined with the city’s high poverty rates, this makes managing asthma even more challenging, as access to proper medical care can be limited.

2. Cleveland, Ohio

Cleveland takes second place as one of the worst cities for people with asthma. The city experiences high rates of asthma cases, emergency room visits, and asthma-related deaths. A significant cause of these issues is high ozone pollution levels. These poor air quality conditions lead to greater reliance on quick-relief asthma medications, such as inhalers, to manage symptoms. Cleveland's pollution levels, coupled with limited resources for asthma care, make it a difficult place for those living with asthma.

3. Allentown, Pennsylvania

Allentown is the third worst city for asthma sufferers. The city faces high asthma prevalence, with an alarming rate of emergency room visits due to asthma. One of the primary triggers in Allentown is the high pollen count, exacerbating asthma symptoms. Additionally, other pollutants contribute to poor air quality, making it a challenging environment for those with respiratory conditions.

4. Lakeland, Florida

Lakeland, Florida ranks fourth on the list of worst cities for asthma. The area sees a high number of asthma cases and related emergency room visits. Unfortunately, residents often have to rely on quick-relief treatments due to the frequency of asthma attacks. The city has a shortage of specialized asthma care providers, and many people lack adequate medical insurance. This combination makes it harder to manage asthma effectively, increasing the need for emergency interventions.

5. Fresno, California

Rounding out the top five worst cities for asthma is Fresno, California. Fresno struggles with poor air quality, particularly high ozone levels and pollution. The area is also lacking in asthma specialists, and the poverty rate is high, further limiting access to care. As a result, asthma cases are prevalent, and emergency room visits related to asthma are common.
