10 Cities to Avoid with Asthma

The Worst Cities to Live in with Asthma in the USA

Asthma, a chronic respiratory condition characterized by airway inflammation and constriction, affects millions across the United States. While various factors contribute to asthma, environmental elements—particularly air pollution—play a significant role in exacerbating symptoms. Several U.S. cities present challenging environments for asthma sufferers due to elevated pollution levels and other contributing factors. Here are ten of the worst cities to live in with asthma, along with explanations of why each poses risks to respiratory health:​

1. Fresno, California

Situated in the San Joaquin Valley, Fresno consistently ranks among the top U.S. cities for poor air quality. The valley's unique geography traps pollutants from vehicle emissions, agriculture and industry, leading to elevated levels of particulate matter (PM2.5) and ozone. These pollutants exacerbate asthma symptoms and contribute to higher rates of respiratory issues among residents.

2. Bakersfield, California

Also located in the San Joaquin Valley, Bakersfield experiences similar air quality challenges as Fresno. The area's high ozone and particulate matter levels are primarily due to vehicle emissions, agricultural activities and oil production. These environmental factors significantly contribute to the prevalence of asthma in the region.

3. Los Angeles, California

Los Angeles is notorious for its smog, resulting from a combination of heavy traffic, industrial activities and a warm climate that facilitates ozone formation. The city's air pollution has been linked to various health issues, including asthma, lung cancer and premature death.

4. West Oakland, California

West Oakland residents are exposed to high levels of airborne toxins due to the neighborhood's proximity to highways and the Port of Oakland. Diesel pollution from these sources contributes to elevated asthma rates and shorter life expectancies in the community.

5. Richmond, California

Home to several oil refineries, including the Chevron Refinery, Richmond's residents face air pollution from industrial emissions and heavy traffic. This pollution has been associated with higher rates of asthma and other respiratory illnesses in the area.

6. Wilmington, Los Angeles, California

Wilmington hosts the highest concentration of refineries in California, leading to significant air pollution from industrial emissions and diesel trucks serving the ports of Los Angeles and Long Beach. Residents face elevated risks of asthma and other health complications due to these pollutants.

7. Shafter, California

In Shafter, numerous fracking sites are located near schools, exposing children to air toxins that may contribute to health issues like asthma and epilepsy. The proximity of these sites to residential areas raises significant public health concerns.

8. New York City, New York

New York City has faced challenges with air pollution, particularly prior to the implementation of the Clean Air Act of 1970. While air quality has improved, certain areas still experience elevated levels of airborne chemicals, contributing to respiratory issues among residents.

9. Omaha, Nebraska

Omaha's air quality is affected by emissions from coal-fired power plants, leading to health issues like asthma and premature deaths. Despite investments in renewable energy, ongoing operations of these plants continue to impact the city's air quality.

10. Bronx, New York

The Bronx experiences high rates of asthma, particularly among children, due to exposure to transportation-generated air pollution. Major highways, bus depots and shipping facilities contribute to higher emission levels, disproportionately affecting low-income communities and people of color.

These cities highlight the critical impact of environmental factors on asthma prevalence and severity. Addressing air pollution through stricter regulations, cleaner technologies and targeted public health initiatives is essential to improve respiratory health outcomes in these regions.
