Regular use of cleaning products may cause significant long-term damage to lung function, according to a new study. Researchers from the University of Bergen in Norway analysed data from nearly 6,000 adults over a 20-year period and found that women who cleaned regularly experienced a greater decline in lung capacity than those who did not.
The study, published in the American Journal of Respiratory and Critical Care Medicine, used data from the European Community Respiratory Health Survey. While previous research had focused on short-term asthma effects, this investigation examined long-term consequences. The authors suggested that chemicals in cleaning products irritate the mucous membranes lining the airways, leading to gradual damage over time.
Professor Cecile Svanes, who led the Bergen team, said: 'We feared that such chemicals, by steadily causing a little damage to the airways day after day, year after year, might accelerate the rate of lung function decline that occurs with age.' The study found no significant difference in lung function decline among men, which researchers said could partly be due to fewer men working as cleaners, but also suggested women may be more susceptible to the effects of the chemicals.
Oistein Svanes, a co-author of the study, said: 'The take-home message is that in the long run cleaning chemicals very likely cause rather substantial damage to your lungs. These chemicals are usually unnecessary; microfiber cloths and water are more than enough for most purposes.'
Commenting on the findings, Sarah MacFadyen of the British Lung Foundation said: 'Breathing in any kind of air pollution can have an impact on our health, especially for those living with a lung condition. This study further confirms that air pollution can come from a range of sources, including from paints, adhesives and cleaning products we use indoors.' She advised that keeping homes well ventilated, using liquid cleaners instead of sprays, and ensuring cookers and heaters are in good working order could help protect lungs.
