Women working as either professional cleaner or housewives involved in cleaning activities have rapid decline in lung functions as compared to women who are not regularly involved in cleaning activities. This decline in lung function is more in a woman who uses cleaning products with or without spray at least once per week as compared to women not performing cleaning activities. Incidence of asthma was more common in women indulging in cleaning activities; being 12.3 % for housewives, 13.7% for professional cleaners as compared to 9.6% for women not indulged in cleaning activities.
Possible mechanism explained for this decline in lung function is probably due to repetitive exposure to cleaning agents which has irritative effect on lung mucous membrane over time. It can also cause remodelling of the airways and fibrotic changes in the lung tissue resulting in reduce functioning lung capacity.
