Simple Switch: Electric Stoves Improve Asthma Control Dramatically

A recent study indicates that switching from gas stoves to electric models can significantly improve asthma control. The research involved 85 participants with poorly controlled asthma who lived in homes with gas stoves. Following the replacement of their gas stoves with electric induction models, participants experienced a shift from moderate to mild asthma symptoms.

Results showed a dramatic 70% reduction in emergency room visits and hospitalizations for asthma. Furthermore, missed work or school days due to asthma decreased by approximately 80%. Concurrently, indoor nitrogen dioxide levels, a known lung irritant, saw a 70% decline. Participants overwhelmingly reported satisfaction with their new electric stoves, with 98% expressing positive experiences compared to only 41% who were satisfied with their previous gas stoves.

The study acknowledges limitations, including a small participant group and a short follow-up period. Potential barriers to adoption include the cost of replacement, which averaged $1,500 for new stoves and up to $7,000 for electrical system upgrades in older homes. However, the findings suggest that government or health insurer subsidies could be beneficial for individuals with poorly controlled asthma.

An example from Ecuador demonstrates the efficacy of such subsidies. From 2015 to 2021, the Ecuadorian government subsidized 750,000 households to switch to electric induction stoves, correlating with a decrease in respiratory illness hospitalizations. While not a cure, transitioning away from gas stoves may offer meaningful symptom relief for many individuals with asthma, who should continue to manage their condition with medical professionals and by avoiding other triggers.
