Straight from the Marshall Phillips Files...
University of Bergen researchers looked at the lungs of thousands of men and women and checked-in with them periodically over the course of 20 years.
They found women who cleaned with spray or liquid cleaning products (either around the house once a week or working as a professional cleaner) had 'accelerated' decline in lung capacity.
The drop in lung function was comparable to smoking a pack of 20 cigarettes a day for ten to 20 years.
No effect was found on the lungs of men who cleaned in any capacity.
Researchers suggest that people stop using bleach to clean often, and add that usually 'water and a microfiber cloth' will complete most cleaning tasks.
