ERSS: Frequent fireplace use linked to heart disease risk
Fireplaces release harmful particulate matter into the air that can be inhaled by the lungs and the bloodstream, according to a study published in the journal Energy Research & Social Science (ERSS).
The researchers analysed the air quality in several homes with open and closed fireplaces. Air samples were collected every 11 minutes for 24 hours. On average, concentrations of hazardous microparticles significantly exceeded the World Health Organization (WHO) guidelines. Pollutant levels remained high for one to three hours after fireplace use, with slightly lower levels in homes with closed fireplaces.
The researchers stressed the need for further research into air quality in homes where fireplace use is mandatory in winter, as residents of such homes may be at increased risk of lung and cardiovascular disease. They also found that long-term exposure to fine particulate matter from fireplaces (over months or years) was associated with an increased risk of cardiovascular disease, lung disease, and respiratory problems in children. WHO recommends avoiding prolonged exposure to these fine particles for more than three days a year.
