People who use household cleaners are at greater risk of chronic obstructive pulmonary disease, including chronic bronchitis and emphysema, according to the study. The study was presented at the European Respiratory Association International Conference in London. Researchers followed 5,000 women for 20 years. The results showed that the average pulmonary function of people who depend on cleaning was 17% lower than that of the general population. Even those who regularly scrub furniture at home suffer 14% more lung damage than others. This is mainly because detergents expose people to chemicals. For example, ammonia stimulates the airway, while other chemicals can cause allergic airway diseases. Therefore, you need to pay more attention to the chemical composition of household cleaners, be aware of the risks, and take measures to mitigate the harm to yourself.
