There is no clear consensus on whether or not gas stoves and ovens are bad for your health. Some studies have found that emissions from gas cooktops can contain harmful pollutants, including nitrogen dioxide and carbon monoxide. These pollutants have been linked to a variety of health problems, including respiratory issues, headaches, and dizziness. Additionally, gas cooktops can release fine particulate matter into the air, which has been linked to an increased risk of heart disease and stroke. However, other studies have found that gas cooktops are no more harmful than electric cooktops and that any potential health risks are relatively low. Ultimately, more research is needed to determine the true impact of gas stoves and ovens on human health.
