Researchers at Texas A&M University School of Public Health studied how the indoor environment affects asthma in adults. The team, led by doctoral student Alexander Obeng, analyzed data on 1,600 adults with asthma collected between 2019 and 2022. Their paper, published in Atmosphere, examined four outcomes: asthma attacks, symptoms, sleep problems and limits on daily activities.
The study identified two major home triggers: lack of exhaust fans in kitchens and bathrooms, and smoking inside the home. People who smoke cigarettes or who do not use air purifiers were more likely to have attacks, frequent symptoms, or trouble sleeping and staying active. Conversely, adults in homes without mold, mice or rats and without furry pets reported fewer problems.
Data showed that women, older adults and Black adults suffered more asthma complications than other groups. The researchers linked these differences to income levels, housing quality and access to health care. They recommended financial help for low-income families, better rules for landlords, and education from health care professionals to remove triggers during checkups.
