According to the Centers for Disease Control and Prevention (CDC), more than 25.2 million people in the United States have asthma. Since May is the peak season for asthma and allergy symptoms, the Asthma and Allergy Foundation of America created this awareness month in May 1984 to help raise awareness at a time of year when asthma affects so many people.

May 2 is World Asthma Day. On this day and throughout May, you can help educate about asthma, participate in events and fundraisers, and show your support.

In 2023, the theme involves debunking myths and misinformation about asthma and allergies, including their causes and how to treat them.

Myths about asthma

Here are a few myths about asthma. Asthma Awareness Month is a time to debunk them.

Myth 1: If you’re not wheezing, you don’t have asthma.

  • Fact 1: While wheezing is a common asthma symptom, there are many reasons you may not hear wheezing during an attack. Sometimes, you need a stethoscope to hear wheezing. If your asthma attack is severe, it may block airflow, stopping wheezing.

Myth 2: Asthma medications are habit-forming.

  • Fact 2: Asthma medications are key to effective asthma management. They aren’t habit-forming and don’t lose their effectiveness over time. Taking your asthma medications as prescribed is important to keep your asthma from worsening.

Myth 3: Asthma is a childhood disease that you eventually outgrow.

  • Fact 3: While asthma usually develops during childhood, people rarely “outgrow” asthma, and it lasts into adulthood. For some people, asthma symptoms may improve as they get older, but there are many reasons why it may worsen or continue to flare up when you’re an adult.

Facts and statistics about asthma

  • In the United States, the number of people with asthma has increased to more than 25.2 million since 2001, but the number of asthma attacks has decreased in that same time, thanks to effective treatments.
  • Additionally, there are nearly 6 million U.S. children under 18 years old with asthma, making asthma a leading cause of chronic illness in U.S. children.
  • Black people in the United States are five times more likely than white people in the United States to go to an emergency room due to asthma, and they are three times more likely to die from asthma than white people. A 2016 study identified a novel genetic change in Black children with asthma that wasn’t as common in children of European or Asian ancestry, suggesting there may be an ethnic genetic component. This also highlights the need to include more Black people in asthma research. Systemic racism and healthcare inequities are likely a major part of this increased risk as well.
  • Ten people in the United States die from asthma each day, and in 2020, deaths from asthma rose for the first time since 2010.
