Gas stoves expose millions in the US to unsafe limits of nitrogen dioxide, and disadvantaged communities face higher risk

Gas and propane stoves in homes significantly increase exposure to nitrogen dioxide, with harmful effects on the health of thousands of people in the United States, according to a recent study. The research found that using a gas stove alone causes people to reach 75% of the suggested annual limit for nitrogen dioxide. Breathing air with high concentrations of nitrogen dioxide can irritate the respiratory system and contribute to respiratory diseases and asthma. Disadvantaged communities, particularly those living in smaller residences, are at a higher risk due to increased exposure. The negative effects of exposure to nitrogen dioxide can occur even in bedrooms distant from the kitchen. Experts recommend minimizing the use of gas stoves, cooking for shorter periods and with lower heat, using well-ventilated spaces, and considering alternatives such as induction cooktops.
