Our Mission

The Nebraska Asthma Coalition strives to improve health outcomes and quality of life for individuals affected by asthma in our state. We work to accomplish our mission through our core values of collaboration, inclusivity, data-driven decision making and commitment to addressing health disparities. 

Environmental and Occupational Exposures and Their Impact on Asthma 

Jill Poole, MD, Professor and Division Chief of Allergy and Immunology 

Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, making it difficult to breathe. It is one of the most prevalent respiratory diseases worldwide, affecting millions of people of all ages. While genetics and family history play a role in the development of asthma, environmental and occupational exposures are significant contributors to both the onset and exacerbation of the condition. These exposures can trigger asthma symptoms or worsen existing asthma, leading to increased healthcare visits, reduced quality of life, and greater economic burden. 

Environmental Exposures 

Environmental factors such as air pollution, allergens, and climate changes are well-established triggers for asthma. Pollutants like particulate matter (PM), nitrogen dioxide (NO2), sulfur dioxide (SO2), and ozone are particularly harmful, as they irritate the airways and induce inflammatory responses. These pollutants are primarily emitted by vehicles, industrial activities, and power plants, making urban areas especially prone to asthma exacerbations. Exposure to secondhand smoke is another key environmental factor linked to the development of asthma, particularly in children. In addition to air pollution, indoor allergens such as dust mites, mold, pet dander, and cockroach droppings also contribute to asthma exacerbations. Homes with poor ventilation, high humidity, or inadequate cleaning practices provide an ideal environment for these allergens to thrive. Additionally, seasonal allergens like pollen can worsen asthma symptoms during certain times of the year, particularly for individuals with allergic asthma. 

Occupational Exposures 

Workplace environments can also play a critical role in the development or worsening of asthma. Occupational asthma is a type of asthma triggered by exposure to substances in the workplace. These substances may include chemical fumes, dust, gases, or allergens specific to a particular occupation. For instance, workers in industries such as agriculture, construction, painting, and manufacturing are at higher risk due to frequent exposure to irritants like pesticides, paints, and industrial solvents. Certain occupations that involve exposure to respiratory irritants or allergens, such as cleaners, healthcare workers, bakers, and those working with animals, have an increased prevalence of asthma. The severity of occupational asthma depends on the intensity and duration of exposure, as well as the individual’s genetic susceptibility to developing asthma. Workers may experience symptoms such as coughing, wheezing, and shortness of breath after exposure to irritants or allergens in the workplace. 

Conclusion 

Both environmental and occupational exposures significantly affect asthma. Individuals living in areas with high levels of pollution or who work in environments with respiratory hazards are particularly vulnerable. Reducing exposure to these triggers through improved air quality, workplace safety regulations, and better indoor environments can help reduce asthma symptoms and improve overall health.
