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."
