The use of cleaning sprays such as bleach in hospitals may be causing a rise in the number of nurses who suffer from asthma, according to a health expert.
Dr Jan-Paul Zock told delegates at a European allergy conference in London that evidence suggested there was a link between using cleaning sprays and asthma.
Dr Zock, of the Centre for Research in Environmental Epidemiology in Barcelona, said breathing in bleach, acids, ammonia, solvents and stain removers more than once a week was linked to a 20% rise in asthma or wheezing.
He added that the rise was also linked to how strong the product was and how well the room was ventilated.
And he said nurses, housekeepers, caretakers, and professional cleaners were most at risk of developing asthma, particularly if they use the products for long periods of time or on a regular basis.
Dr Zock said while some people were more susceptible to the effects than others, “the number of people at risk is very large”.
