Heat waves can trigger asthma

Young child holding an asthma inhaler with a spacerSpikes in mold, dust mites, pollens, and air pollution levels on hot, humid days can trigger asthma and allergy attacks. Follow these steps to manage your asthma during heat waves so you can breathe easier:

  1. Take your "controller" medications regularly as directed by your asthma healthcare provider. Don't have an Asthma Action Plan? Ask your provider to fill one out for you at your next asthma appointment.
  2. Always carry a rescue inhaler and spacer with you, especially on hot and humid days.
  3. Check the air quality before heading outdoors on hot days. Better yet, sign up to receive air quality health advisories in your inbox or text.
  4. On hot days, stay inside if you can. Consider exercising indoors or in the morning before the temperatures climb and air quality is impaired.
  5. Know the signs and symptoms of an asthma attack and seek help at urgent care or the emergency room if you rescue medications don't provide relief.

About the Asthma Program

 COVID-19 impact on Asthma

All people ages 5 and older are eligible for the COVID-19 vaccine. We encourage people with asthma to get vaccinated. Find a vaccination appointment near you.

The Wisconsin Department of Health Services has been conducting asthma surveillance activities since 1992 and asthma interventions since 1994.

Since 2001, the Wisconsin Asthma Program has expanded its activities under a cooperative agreement with the U.S. Centers for Disease Control and Prevention (CDC).

In 2003, the first Wisconsin Asthma Plan was adopted to provide the blueprint for addressing asthma as a public health priority, and lists the prioritized goals, objectives, and activities recommended for statewide action to reduce the burden of asthma in Wisconsin. The updated 2021-2025 plan is now available.

The Wisconsin Asthma Program partners with the Wisconsin Asthma Coalition to achieve the goals and activities in the Wisconsin Asthma Plan.
