Your Range Hood Could Be One of the Best Things for Your Kids' Health
A new study published in the Journal of Exposure Science & Environmental Epidemiology (2025) by Dr. Stephanie M. Holm, Dr. Brett C. Singer, and colleagues at UC San Francisco, UC Berkeley, and Lawrence Berkeley National Laboratory found something surprising — and encouraging: just watching a 4-minute video changed how families cooked, and it measurably cleaned up the air in their homes.
If You Cook with a Gas Stove, This Is Worth Knowing
Here's something a lot of people don't realize: every time you fire up your gas stove, it releases invisible pollution right into the air you and your family breathe. We're talking about gases like nitrogen dioxide (NO2) and tiny particles called PM2.5. The same stuff we worry about in outdoor smog. But it's happening in your kitchen.
In fact, researchers have found that nearly half of homes with gas stoves exceed the EPA's outdoor air quality standard for NO2 during a typical cooking session. With roughly 40 million homes in the US still cooking with gas, that's a lot of people unknowingly breathing poor-quality air, including their kids. Children with asthma are especially vulnerable, and studies have linked higher indoor NO2 levels to more frequent asthma symptoms, nighttime inhaler use, and coughing.
The Good News? A Simple Habit Change Makes a Real Difference
Here's where this study gets really encouraging. Researchers worked with families in the San Francisco Bay Area who had gas stoves and kids at home. They showed them a 4-minute educational video. Nothing complicated, just clear tips and measured the air quality in their homes before and after.
The results? After watching the video, families started using their back burners more and turned on their range hoods more often during cooking. That's it. No expensive equipment. No major renovation. Just two small habit shifts. And the air quality in their homes improved significantly. NO2 levels dropped in a meaningful, measurable way. The researchers note this kind of simple, low-cost intervention could be especially helpful for families with kids who have asthma or other breathing conditions. The takeaway for you: turn on your range hood every time you cook, and use your back burners when you can. It really does matter.
