Asthma and Environment FAQs

What are some examples of environmental pollutants that can trigger asthma attacks?

Air pollution can trigger attacks and make asthma symptoms worse. Two key air pollutants can affect asthma: ozone and particle pollution. When ozone or particle pollution are in the air, adults and children with asthma are more likely to have difficulty breathing.

Ozone is often worst on hot summer days, especially in the afternoons and early evenings. Particle pollution can be bad any time of year, even in winter. Particle levels can also be high near busy roads, during rush hour, and around factories and when smoke is in the air from wood stoves, fireplaces, forest fires or burning vegetation.

How is asthma impacted by climate change in Vermont?

A lengthening growing season and increased plant growth due to higher levels of carbon dioxide in the air will likely increase allergenic pollen in the air we breathe. This could have widespread respiratory impacts to Vermonters, especially those with asthma.

More frequent heavy precipitation events and other severe weather events—such as high winds, flooding, and winter storms—can cause water damage to buildings, increasing problems with household mold. Climate-induced increases in indoor dampness can increase health problems related to dampness and mold, such as worsening asthma.

Vermont Asthma Program

The Vermont Asthma Program is funded by the Centers for Disease Control and Prevention (CDC) to create an asthma prevention program and to maintain and enhance an asthma surveillance system. Asthma surveillance is the ongoing systematic collection, analysis, and interpretation of asthma-related data for use in planning, implementation, and evaluation of related public health activities. Asthma surveillance data helps to direct and inform the activities of the Vermont Asthma Program and their partners as well as provides information to the public about asthma in their communities.
