The problem Whenever we burn anything inside our homes, we cause indoor air pollution, whether we’re cooking using gas, frying bacon, lighting a wood burner, an open fire, a cigarette or incense, or ruining the toast. “ We spend 80-90% of our time indoors,” says Prof Francis Pope, chair of atmospheric science at the University of Birmingham. “And there is potential to have quite high concentrations of pollution indoors. This affects your respiratory and cardiovascular systems; certain components are carcinogenic, and there’s a growing body of evidence that air pollution affects cognition. In the long term, you get awful diseases such as dementia and Alzheimer’s. But relatively short exposures to air pollution are linked to things like educational outcome, workplace productivity and general mental wellbeing.”
