Even in modern homes, the air we breathe indoors can quietly affect our health. And one small change can make a big difference.
Research shows that tiny particles from fires, stoves, and log burners can linger in the home, which can have negative impacts on human health in many ways. The World Health Organization estimates that indoor air pollutants from sources like fires are responsible for 3.2 million premature deaths every year from illnesses including heart disease, stroke, and lung cancer.
"Quite how harmful these particles are to an individual's health is hard to quantify but, as well as affecting your lungs, the smaller particles can carry nasty chemicals into your bloodstream, causing premature ageing of the cardiovascular system," explained Dr. Mark Porter, NHS GP and columnist for the Sunday Times.
The good news is that there are practical solutions to reducing risk.
"Researchers suggest reducing exposure by minimising burning time … opening windows periodically and only burning seasoned or kiln-dried wood," Porter noted. "To which I would add not opening the door on your stove unless you have to and considering using an air filter."
High-efficiency particulate air (HEPA) filters reduce the smallest particles from fires and stoves, which have potential benefits for cardiovascular health. Research suggests that using HEPA filters at home can help improve blood flow, lower inflammation, and reduce blood pressure. They also remove allergens, which benefits people with allergies and asthma by reducing symptoms such as coughing, wheezing, and blocked noses. And these benefits often happen after days, not weeks.
HEPA filters can even help protect from outdoor air pollution. This is beneficial since, as our planet continues to heat up, it is likely that air quality will continue to get worse as natural sources of air pollution increase by 14%.
