Replacing gas stoves with electric stoves greatly reduces asthma symptoms
8 hours ago
- Over one-third of U.S. households use natural gas stoves, which produce indoor air pollutants like nitrogen dioxide that can worsen asthma.
- A study replaced gas stoves with electric induction stoves for 85 participants with poorly controlled asthma, finding significant symptom improvements.
- After switching, asthma symptoms shifted from moderate to mild, emergency visits dropped 70%, and missed work/school days fell by about 80%.
- Indoor nitrogen dioxide levels decreased by 70%, and 98% of participants preferred electric stoves over gas stoves.
- Cost and electrical upgrades are major barriers, especially for low-income communities, but subsidies could help, as seen in Ecuador.
- The study had limitations, including a small sample size, short follow-up, and lack of a comparison group.
- Switching stoves is not a cure, but patients with poorly controlled asthma may benefit; physicians should discuss stove use and alternatives.
