Replacing Gas Stove Benefits Asthmatics Equivalent to Medications 2026

Replacing a gas stove with an electric alternative can improve asthma symptoms as much as common medications, according to a new US pilot study. Researchers from Case Western Reserve University and Ohio’s MetroHealth system found a 70% drop in hospital admissions and missed work or school days among people with poorly controlled asthma after the swap.

The Study That Almost Wasn’t

The project began in December 2024 intending to enroll 1,200 participants living near Cleveland, Ohio. However, funding was terminated early by the incoming Trump administration. Lead researcher Prof Ash Sehgal said: “We had completed the project at fewer than 100 households. Over 1,100 households were unable to benefit.” The team finished replacements already underway and closed the project, but the scaled‑down analysis of 72 homes still revealed striking results.

Asthma Improvement Comparable to Drugs

Each participant was assessed four weeks before and four weeks after switching from a gas stove to an electric one. Asthma severity was scored using a zero‑to‑six international scale. The average score dropped from 2.6 to 1.5 — a change of 1.1, far above the 0.5 considered clinically significant. “The improvements were similar to – or even greater than – those reported in clinical trials of commonly used asthma medications,” Sehgal said.

How Gas Stoves Harm Breathing

Gas stoves emit nitrogen dioxide (NO₂) and other pollutants. In the study, indoor air pollution measurements in 44 homes showed NO₂ levels fell by 70% after the switch. Participants experienced less wheezing, fewer night‑time awakenings, and reduced reliance on rescue inhalers.

Angela Bland, a 38‑year‑old resident of Akron, Ohio, said: “I didn’t realise my gas stove was the issue until I used the electric stove. I now need my inhaler way less often.”

Comparison: Gas Stove vs Electric Stove for Asthma

Key Takeaways

• Replacing a gas stove with an electric model can yield a 70% reduction in asthma‑related hospital visits and lost school or work days.
• The effect on symptom severity rivals that of prescription asthma medications.
• Indoor nitrogen dioxide levels drop dramatically after the switch.
• Immediate benefits include less wheezing, fewer night awakenings, and decreased reliance on inhalers.

FAQ

For those with asthma, the evidence is clear: switching from gas to electric cooking can be a powerful, non‑pharmaceutical intervention. While larger studies were cut short, the pilot data strongly suggests that replacing a gas stove should be considered alongside medication for managing poorly controlled asthma.
