Allentown has been named the worst place to live in the United States for people with asthma, according to the Asthma and Allergy Foundation of America's 2026 Asthma Capitals report. The region ranks first nationally for asthma-related emergency department visits, though its asthma death rate remains average. This marks a troubling trend: Allentown was ranked worst in 2021, 2023, and 2024, third worst in 2022 and 2025, and has also been identified as one of the most polluted metropolitan areas by the American Lung Association.

What Makes Allentown Such a Difficult Place for Asthma Sufferers?

Asthma is more than just a single condition. It's an umbrella term for a group of physical phenomena involving airway hypersensitivity, baseline airway inflammation, and reversible airflow obstruction, according to medical experts in the region. The causes and risk factors are numerous and interconnected. While roughly 8% of Americans have asthma, certain areas and populations face significantly higher risks.

The Lehigh Valley's geography and environment create a perfect storm for asthma sufferers. Air quality plays a measurable role; areas near highways have higher incidences of asthma. However, experts emphasize that indoor air quality may actually be a bigger contributor than outdoor pollution. People living in lower-quality housing where they're exposed to mice, cockroaches, and mold face elevated risk. Additionally, the Lehigh Valley is a particularly bad area for allergies, which directly translates to higher asthma rates among residents.

Certain populations face disproportionate risk. Puerto Ricans are at higher risk than the general population, and boys are more likely than girls to develop asthma during childhood, though this pattern reverses after high school.

How Can People With Asthma Take Control of Their Condition?

• Identify and Avoid Triggers: Figuring out what specifically triggers your asthma symptoms and modifying your lifestyle and environment accordingly is one of the simpler yet most effective strategies. This might mean avoiding certain allergens, staying indoors during high pollen days, or reducing exposure to smoke.
• Monitor Air Quality: Check airnow.gov regularly to view your region's air quality and assess daily risks. This allows you to plan outdoor activities during cleaner air days and take preventive measures when pollution levels rise.
• Install Air Filtration: Those with severe allergies should consider getting a HEPA filter for rooms where they spend most of their time, such as bedrooms or home offices.
• Protect Against Respiratory Infections: Certain respiratory viruses become more common at the beginning of the school year and can affect people with asthma more severely. Hand washing and getting the influenza vaccine are effective protective measures.
• Develop a Safety Plan: Having a clear action plan for when an asthma episode begins is critical. This plan should include keeping a rescue inhaler readily available, maintaining an adequate supply of maintenance inhalers, and consulting regularly with a healthcare provider.

The key to managing asthma effectively is medication adherence.

"If you have anything more than rare symptoms, in general we like to treat that underlying inflammation to prevent the exacerbations from happening and I think that's the key is being adherent with your asthma medications to prevent exacerbations, not just treating when you have symptoms," said Dr. Robert Zemble of Lehigh Valley Health Network.

This means taking maintenance medications regularly, not just using rescue inhalers when symptoms appear.

Environmental modification remains central to asthma management.

"Those things aren't changing and you know some of them can't change. So we have to figure out how we're going to manage these for ourselves. And you know if you go to the allergist and you can get desensitized through shots, that's great, but a lot of people can't do that," said Chrysan Cronin, director emeritus of public health at Muhlenberg College.

For those with severe allergies, immunotherapy (allergy shots) can help desensitize the immune system, though this option isn't available to everyone.

Residents of high-risk areas like Allentown shouldn't feel helpless. While external factors like air quality and housing conditions present real challenges, taking proactive steps to identify personal triggers, maintain medication routines, and monitor environmental conditions can significantly reduce asthma exacerbations and emergency room visits. Working closely with allergists and primary care physicians to develop a personalized management plan is essential for anyone living in a region with elevated asthma risk.
