People who use spray cleaners on a regular basis may want to reconsider how they tackle their spring cleaning. A new study published in the American Journal of Respiratory and Critical Care Medicine [PDF] offers strong evidence that inhalation of these sterilizing and polishing chemicals may be as bad for their lungs as smoking one pack of cigarettes per day, as Newsweek highlights.
A team of scientists led by Cecile Svanes, Ph.D. at Norway’s University of Bergen tracked 6230 study subjects for two decades, looking for a correlation between diminished lung capacity and use of cleaning products. Those who regularly used chemicals for cleaning, like housekeepers, displayed worsening lung function when researchers asked them to blow air into a tube. Even using cleaners once per week was associated with reduced lung capacity.
Those who reported use of the products also had increased rates of asthma when compared to those who did not use cleaners. It’s believed the particles of the abrasive chemicals are damaging the mucus membranes, leading to steady and progressive changes. The results applied to both occupational cleaners as well as those who were responsible for cleaning at home. The study also demonstrated that women were more susceptible to the effects of the chemicals than men, although a comparatively smaller number of men took part.
What can you do to mitigate the risk? Oistein Svanes, a doctoral student who worked on the project, recommends cleaning with a damp microfiber cloth using only water. If you feel you must use a chemical agent, it's better to pour it into a bucket instead of relying on a spray nozzle—the latter is what causes the chemicals to become airborne and respirable.
