Asthma is a common, serious and difficult-to-manage chronic health condition. In the U.S., 1 in 7 people are diagnosed with asthma, and that number is rising.
Over the years, researchers have identified a mix of individual and environmental factors that play a role in asthma. For instance, obesity and alcohol use increase a person’s risk for asthma. And more extreme weather is linked to worse asthma symptoms.
