Clear the air, breathe easy!

The hidden danger of gas stoves are well documented. The health risks of this cooking appliance are affecting us and our families, especially our children.
The big question now is: What do we to do about it?

We’re ringing the alarm, and it’s something that half of Canadians don’t even know about. Why gas stoves? Well, now we know that they emit nitrogen dioxide, benzene, carbon monoxide and other pollutants, even when the flame is off. Dozens of studies have found that your gas stove could be making you and your family sick.

Really sick, that is. The emissions from gas stoves have been linked to respiratory illnesses like asthma, other respiratory diseases and even cancer. Studies show that exposure to gas stoves can increase a child’s asthma risk by more than 40 per cent. Simply opening a window or turning on a fan, is not enough; depending on the wind direction and ventilation set up, doing so might actually help spread the chemicals farther into your home.

In fact, research shows that the health risks associated with using a gas stove are comparable to second-hand smoke in your home. It’s practically impossible to meet safe indoor air quality guidelines with a gas stove, says Dr. Melissa Lem, a board member at the Canadian Association of Physicians for the Environment (CAPE), who sees firsthand the impact that poor air quality has on her patients. "When we breathe clean air, we breathe easier." she adds.

Gas stoves can emit harmful chemicals even when they’re not in use. After turning off your stove, the nitrogen oxides that were released during cooking can linger for hours, and accumulate to levels that surpass Health Canada’s guidelines for indoor air quality, possibly creating an unsafe environment in your home.

 

Aren’t gas stoves the gold standard for cooking?

It’s true, gas stoves were marketed this way, but technology has come a long way. And high-performing alternatives like induction cooktops are available now; they work by heating the pan, not the stovetop, providing fast and precise heat. The best part? They’re a safer option for kids in the kitchen.

 

Why the focus on gas stoves only? What about other appliances that use gas?

A gas stove, furnace, fireplace, or water heater could all be adding risk to your family’s health. But with gas stoves in the kitchen, you are directly exposed to the emissions. Water heaters and other gas appliances are usually sealed off from the main living area.

 

What To Do?

• Be informed

Educate yourself by looking at the research, so you can make informed decisions with accurate information. A good place to start is the Canadian Association of Physicians for the Environment website, Heat Cook Breathe.

 

• Invest in an electric stove

If you’re in the market for a new stove or replacing an old one, look for an electric one. However, if your rent an apartment or condo, or can’t afford to do this now, you can try to mitigate the risk by using other cooking methods like your microwave more often. You could also look into purchasing a portable countertop electric induction burner or use an electric kettle to boil water.

 

• Consider getting a heat pump

A heat pump is an efficient alternative to a gas furnace, and doubles as an air conditioners during the summertime. It's cost-effective and cheaper than running gas and air conditioning. Bonus: One study found that heat pumps are much more efficient than gas furnaces in cold temperatures. It’s a win-win—a home that stays toasty in winter and cool in summer, while saving money and reducing pollution at the same time. 

 

• Search for government rebates

Designed to help people transition away from gas, some regions have initiatives to encourage switching to energy-efficient appliances. The City of Toronto, for instance, offers up to $2,500 for Home Energy Loan Program participants when they install a heat pump.

 

Protect the Environment

Outdoor air pollution is a mix of many substances, including nitrogen dioxide. Buildings, including houses and apartments, contribute almost 20 per cent of the total nitrogen dioxide found in air pollution—and that’s mainly due to natural gas usage. Gas furnaces are vented to the outdoors, which means that pollutants are released into your yard and neighbourhood, increasing local air pollution, which in turn, can also lead to disease. And don’t forget: A range hood contributes to outdoor air pollution too. Make sure outdoor furniture and areas where friends and family gather are well away from exterior vents.

 

The Number 1 Thing: The Hidden Cost

Ultimately, it’s true, replacing your stove can be costly for all of us, but especially for young families. But ask yourself: Why do we continue to accept the risks associated with a gas stove? Think about this—the hidden cost is greater than dollars and cents. It’s about protecting your health, your family's health, and the environment.
