The EPA Cut Short a Gas Stove Study — the Results Are Alarming

A July study revealed a startling link between gas stoves and asthma symptoms, conducted by MetroHealth System in Northeast Ohio and funded by the EPA for three years. However, the study was abruptly cut short by the Trump administration in May 2025. Dr. Ashwini Sehgal, a professor of medicine at Case Western Reserve University, stated that this is the first research to examine if switching from gas to electric stoves can reduce asthma symptoms.

The study included 85 adults and children with poorly controlled asthma, who switched to electric induction stoves at no cost, with air quality monitors measuring nitrogen dioxide levels before and after the switch. Results showed a 70% decrease in indoor nitrogen dioxide levels and improvements in asthma symptoms, missing work or school days by 80% and ER visits and hospitalizations by 70%.

98% of participants felt satisfied with their new electric stoves, while 41% had the same satisfaction with their previous gas models. However, the study's small sample size, short duration, and reliance on self-reported questionnaires limit its applicability to people with mild asthma or other US regions. Further research is needed to confirm these findings and understand long-term outcomes.

Gas stoves emit gaseous pollutants, including nitrogen dioxide, which can cause cancer and various health issues. Despite the study's results, switching to an electric stove should not replace medical care and other health precautions.
