A recent study, released in July 2026, explored whether replacing gas stoves with electric stoves could improve asthma control among individuals with poorly controlled asthma. Through a US Environmental Protection Agency (EPA) project, MetroHealth System and six Northeast Ohio community organizations provided electric stoves to 85 individuals with poorly controlled asthma and assessed changes in asthma control 2-3 months after the stove replacement.
The researchers found that asthma control improved following the stove replacement, with average Asthma Control Questionnaire scores decreasing from 2.6 to 1.5. Participants also experienced fewer recent emergency room visits or hospitalizations for asthma, as well as fewer missed work or school days. Indoor nitrogen dioxide (NO2) also decreased substantially, from 21.0 to 6.3 parts per billion. Based on these results, the study suggests that transitioning from gas to electric stoves may improve asthma control, but more research is needed to confirm these findings and understand the long-term effects.
