Switching to electric stoves is recommended, but renters and those with financial constraints may struggle to make the change. This is significant, as asthma is more common in disadvantaged areas. Nearly 9% of Australian children suffer from asthma, a condition worsened by exposure to indoor pollutants.
Gas stoves release toxic chemicals, including nitrogen dioxide, carbon monoxide, and formaldehyde. Nitrogen dioxide is especially harmful, as it can trigger and worsen asthma. Gas heaters also produce nitrogen dioxide, making it essential to monitor air quality.
Using high-efficiency exhaust hoods over gas cooktops can reduce indoor pollutants by over 75%. However, many people don’t use exhaust hoods regularly, and for those unable to install them, simply opening windows while cooking can improve air quality.
In winter, unflued gas heaters—commonly used in colder regions—release pollutants into the home. Flued gas heaters or electric alternatives are better options for reducing asthma triggers.
While asthma can’t be cured, improving indoor air quality, even in older or rented homes, can help manage symptoms and create a healthier living environment for children.
