Researchers at a university in Norway followed 6.235 people for over 20 years, collecting data on their health and behavior. What they found should make us all think twice about using chemical cleaners. In one example, forced vital capacity (FVC)—a measurement frequently used to assess lung strength and capacity—declined much more quickly for women frequently exposed to cleaners. Specifically, the data showed a 4.3 mL/year faster decline for women who cleaned at home and a 7.1 mL/year faster decline for those who worked as professional cleaners.
What does this mean in real life? This increase in decline was comparable to 10 to 20 pack-years of tobacco smoking. "Pack-years" is a term used by clinicians to measure tobacco smoking and is calculated by multiplying the number of packs of cigarettes smoked per day by the number of years the person has smoked. They also found that asthma was 12 to 13 percent more common in women who frequently used cleaners. "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." Cecile Svanes, M.D., Ph.D., one of the study's authors and a professor at the university, explained to ScienceDaily.
