Dr Michael Mosley has issued a warning to anyone with a gas hob at home.
It comes as a new study explored how much of a damaging impact in-house pollution can have to our health. According to research by Nature, the world's leading science journal, 3.2m people worldwide are killed by indoor pollution.
Writing in the Daily Mail, Dr Mosley, who is usually known for his weight loss advice, warned: "There has been a lot of research — and concern — about the quality of the air outdoors. But it's increasingly clear that we're also suffering the impact of the poor quality air in our homes."

PM (particulate matter) 2.5, is the most damaging air pollutant known to human health and has been shown to increase your risk of developing cancer, heart disease, dementia and even shown to cause mental illness in children. Shockingly, this is being found increasingly inside people's homes from appliances families use every day, reported Coventry Live.
If you cook with a gas hob, Dr Mosley recommends taking action to prevent dangerous emissions from entering your body. He says: "Cooking with gas and gas boilers produces PM2.5s...the 2.5 relates to the particle size, so these have diameters 2.5 micrometres or smaller (a human hair is about 70 micrometres)."
"What makes them dangerous is that they can penetrate deep into our lungs, then travel through our blood to organs such as the heart and the brain." To reduce the amount of 2.5 pollution in your home, Dr Mosley says: "Make sure your house is well ventilated.
"It is particularly important when you are cooking with gas to turn on the overhead extractor fan, if you have one. Overall it is healthier to bake than to fry."
Dr Mosley added: "As well as damaging our hearts, lungs and brains (it's been linked to cognitive decline and dementia), inhaling polluted air affects our mood. In a study published earlier this month in the journal JAMA Psychiatry, based on the health records of nearly 400,000 Brits, people who were exposed to the least amount of air pollution were found to have the lowest levels of depression and anxiety."
