"Regular use of bleach and other common disinfectants has been linked to a higher risk of developing fatal lung disease, researchers have found.
The use of disinfectants is linked to a higher risk of developing chronic obstructive pulmonary disease (COPD), according to research looking at incidence of the disease in more than 55,000 nurses in the US.
The 30-year study by Harvard University and the French National Institute of Health and Medical Research (Inserm) found that those who used the products just once a week had as high as a 32% increased chance of developing the condition."
