A stove is the centerpiece of your kitchen. Like your refrigerator, it's an appliance that's used a lot. That ever-present quality can make your range feel unremarkable — but in recent years, gas stoves have become the subject of headlines and legislation.
Video of the Day
Many cities — including New York, Los Angeles and Berkeley — recently banned gas stoves (along with gas-powered heaters and boilers) from new buildings, with Berkeley being the first to enact this type of ordinance in 2019.
And, in 2022, the American Medical Association (AMA) passed a resolution calling for education about the health-related risks of gas stoves, along with supporting programs to encourage an equitable transition to electric stoves.
If you're part of the roughly 35 percent of Americans who use a gas stove, per the U.S. Energy Information Administration, here's what you need to know.
How Gas Stoves Can Affect Your Health
When you cook food using a gas stove, it leads to the emission of carbon monoxide, various pollutants, formaldehyde and particulate matter, says Qunfang (Zoe) Zhang, an air pollution specialist at the Health and Exposure Assessment Branch in the California Air Resources Board's Research Division: Air.
This affects the quality of the air inside your home — and that, in turn, can affect your health.
"These gas byproducts may be implicated in causing or exacerbating respiratory illness," says Jonathan Moore, MD, a pulmonology fellow at Lenox Hill Hospital.
At the center of the conversation: Nitrogen oxides (NOx), which includes both nitric oxide (NO) and nitrogen dioxide (NO2), per the U.S. Department of Energy.
Exposure to nitrogen dioxide is hard on people with asthma and increases the risk of respiratory infections, according to the Environmental Protection Agency (EPA). And using a gas stove can lead to nitrogen dioxide levels that exceed both indoor and outdoor standards, per a 2020 report from the Rocky Mountain Institute, a nonprofit organization focused on a move to clean energy.
Nitrogen dioxide can lead to significant inflammation in the lungs, says William Checkley, MD, PhD, who specializes in intensive care medicine and is currently researching the association between household air pollution and lung function.
There's a link between nitrogen dioxide and COPD, per a May 2018 meta-analysis in Environmental Science and Pollution International.
And, for children, growing up in a home with a gas stove is tied to a 42 percent higher risk of having asthma currently and a 24 percent higher risk of developing it during their lifetime, per an August 2013 meta-analysis in the International Journal of Epidemiology.
Cooking with heat leads to the formation of particulate matter, or teensy-tiny particles in the air. The smaller the particles, the bigger the concern because they can more easily be inhaled, per the EPA.
Once you breathe in particulate matter, it can then affect your heart and lungs, according to the EPA.
And, while all cooking may lead to the release of particulate matter, gas stoves lead to higher amounts than electric ones, per a May 2017 study in the Science of the Total Environment. Other factors, such as cooking method, burner size, cooking oil and more, may also affect the volume and size of particulate matter.
Often deemed the silent killer, carbon monoxide is a gas that can be deadly at high levels, Zhang says. But low or moderate levels of carbon monoxide can also have health effects. These range from fatigue to impaired brain function, according to the EPA.
Carbon monoxide levels are higher in homes with gas stoves than homes that don't have one — and they're higher still near poorly adjusted stoves, according to the EPA.
Plus, there's the environmental impact of burning gas, Dr. Checkley says. "Burning gas in itself is leading to a carbon footprint," he says.
Gas stoves release the greenhouse gas methane — even when they're not in active use, according to a January 2022 study in Environmental Science and Technology.
Across all homes with gas stoves in the United States, the amount of methane released each year could have a similar environmental effect as the carbon dioxide emissions of half a million cars, per the study.
Putting It All Together
Here's what we can conclude about gas stoves: Using one — particularly without ventilating (more on that in a moment) — has a real effect on indoor air quality. And that air plays a similar role to outdoor air when it comes to developing or exacerbating pulmonary disease, Dr. Moore says.
"However, establishing a causal link between indoor cooking with gas stoves and development of respiratory illnesses is limited based on the study methodologies," Dr. Moore says. That is, isolating the effect of a gas range from other factors that might contribute to asthma and other respiratory conditions is challenging.
"Asthma, and most diseases in general, is a complex interaction between an individual's genetics, environment and exposures," Dr. Moore says.
Ventilation Is Key
If using a gas stove causes a variety of unpleasant gasses and other pollutants to gather in the air inside your home, one important strategy is to usher these pollutants outdoors.
To do that, use a range hood that vents outside, according to the California Air Resource Board (ARB). Use the back burners when possible since the vent works most effectively on them, per ARB.
Most importantly: If you have a vent, use it whenever you cook.
In one small study, which looked at 71 residences in California for a week, range hoods were only used 36 percent of the time while cooking in homes, and 28 percent of the time in apartments, per the December 2020 research in the International Journal of Environmental Research and Public Health.
Not everyone has a range hood, and if you're a tenant, getting one in place may not be possible. In that case, take up other strategies to ventilate, like opening windows and doors and using fans, according to ARB.
So, Is Using a Gas Stove Dangerous?
That's hard to determine. Gas stoves likely produce more indoor air pollutants than electric ones.
"There is an idea that electric stoves would probably produce less of these pollutants, and definitely there would be a greenhouse gas benefit," says Patrick Wong, a manager in the California Air Resources Board's Research Division: Air.
But, more work is needed to connect the dots, Wong says.
The AMA resolution goes far, saying "our American Medical Association recognizes the association between the use of gas stoves, indoor nitrogen dioxide levels and asthma." And the resolution further encourages implementing mitigation strategies.
None of the experts suggested discarding a stove as the immediate answer. In fact, Dr. Checkley uses a gas stove with the range hood on to avoid exposure to byproducts at his home.
The reality is, many things — including health, affordability, accessibility and personal preference — affect your choice when it comes to a stove, Zhang says. Price is a huge factor. And for renters, a switch to electric isn't always feasible.
The final part of the AMA resolution: A call to advocate for programs that help make the transition from gas to electric stoves equitable.

What to Know Before You Cook With an Electric Stove
If you do opt to transition to an electric stove, be prepared to feel like a newbie cook once again. Here's what you need to know:
Electric vs. Induction
There's a difference between electric stoves — with their classic red coils in place of gas burners — and induction stovetops.
Both types are powered by electricity, but a standard (or coil) electric range works by creating heat, some of which goes into the air, and some of which heats the cookware, says Rachelle Boucher, executive chef and electric kitchens expert at Kitchens to Life. Induction, on the other hand, has a copper coil that connects directly with the cookware, heating it up, she says.
The result: an increase in heat efficiency, which means that the kitchen may feel less steamy and a pot of water will come to a boil incredibly quickly, Boucher says. Plus, you can put a piece of paper next to the induction burner and it won't go up in flames. Only the pot gets hot, she says.
Get Accustomed to New Ways to Regulate Heat
With any type of electric stove — induction or coil — you lose the ability to gauge the heat level by looking at the flames.
That can feel challenging at first. But with time, you'll adjust, taking your cues from the food, Boucher says. You'll know to increase or decrease the heat by the sizzle of your onions or the bubbles appearing around the edges of pancakes.
Plus, you won't have instant heat with a standard electric stove, says Roger Sitrin, lead recreational chef instructor at the Institute of Culinary Education. Unlike a gas stove, where the flame responds immediately to dial adjustments, "with electric stoves, you must allow the element time to heat up and cool down," Sitrin says.
Once the electric stove is on, it'll cycle — as an oven does — to maintain the heat, he says. And even when you turn it off, a standard electric stove will remain hot.
"When cooking on electric stoves, you must move the pan off the element when you want to stop the cooking process," Sitrin says.
Your Pots and Pans May Need an Update
For an induction stove, nearly all the pots and pans you already use — a dutch oven, cast-iron, nonstick and so on — will work.
All aluminum or all copper pans won't work, but clad copper will, she says.
With a standard electric stove, you may need to make some adjustments.
"Old, thin, banged up pans won't work so well on your electric stove," Sitrin says. Opt for enameled cast iron pans, copper pans and clad pans with multiple layers, he says. And make sure they have a flat bottom, to connect with the range, he adds.
You can confirm if a piece of cookware will work on an induction stove by trying to put a magnet on the bottom, Boucher says. “As long as a magnet sticks to the bottom of the pan [it’ll work],” she says.
On an Electric Range, Try Using Multiple Burners for the Best Effect
Going from a rapid boil to a simmer can be hard on an electric range because the element maintains heat, Sitrin points out.
"I've gotten around this by using two burners. I set one on high for boiling and then a second on simmer, then move my pot from the hot burner to the cooler one," he says.
