Gas-to-electric stove swaps linked to asthma symptom relief in Cleveland
A Cleveland project reports larger asthma symptom improvements after gas stoves were replaced with electric ones, but researchers say randomized trials are needed.
The story in focus
A Cleveland study found that 85 people with poorly controlled asthma reported symptom improvement about two to three times larger than typical medication effects after replacing gas stoves with electric ones. Researchers attributed the work to EPA funding, and it was cut short when the Community Change Grants were terminated.
- Eighty-five participants with poorly controlled asthma reported symptom improvement after switching to electric stoves.
- The reported gains were roughly two to three times larger than what is typical with asthma medication, per Science News.
- Participants reported fewer emergency or hospital visits and less missed work or school.
What the Cleveland project found
Science News reports that a project led by Ashwini Sehgal of Case Western Reserve University installed electric stoves in Cleveland households with at least one person with asthma, using initial funding from the U.S. Environmental Protection Agency. Eighty-five participants with poorly controlled asthma were surveyed a few months after the switch.
They reported symptom improvement roughly two to three times as large as what is typical with medication, according to Science News. Those with the worst symptoms saw the biggest improvement, and participants also reported fewer emergency room or hospital visits and less missed work or school.
Pollutant exposure and practical advice
The article notes that burning gas releases pollutants including nitrogen dioxide, which can trigger asthma symptoms, and that stovetop NO2 levels can reach hundreds of parts per billion, above the EPA one-hour outdoor air quality standard of 100 parts per billion.
For households unable to replace a stove, experts quoted by Science News recommend kitchen ventilation, an exhaust hood venting outdoors or an open window, and a HEPA filter with a carbon insert. Sehgal suggested trying an electric hot plate and toaster oven first.
Limits and next steps
The project was initially funded to follow 1,200 households for 12 months, but the Trump administration terminated the EPA Community Change Grants early, sharply reducing participants. Researchers called for randomized trials measuring lung function before and after a switch and accounting for seasonal effects. Sehgal said insurers should consider paying for or subsidizing stove swaps if the link holds.
How many people with asthma took part in the Cleveland stove-swap survey?
Eighty-five participants with poorly controlled asthma were given a questionnaire a few months after switching to electric stoves, according to Science News. The project was originally funded for 1,200 households.
