Being too clean can actually make people sick, suggests a finding by few researchers.
All the data required for the study was collected from the 2003-2006 National Health and Nutrition Examination Survey in America. Certain microorganisms are beneficial for the proper development of our immune system but living in very clean and hygienic environments impacts our exposure to these microorganisms.
AdvertisementOverexposure of children and teenagers to antibacterial soaps that contain the chemical triclosan were more likely to be diagnosed with hay fever and other allergies.
Triclosan is an antimicrobial agent. It is widely used in products such as antibacterial soaps, toothpaste, medical devices and diaper bags.
The study also found that an adult's immune system may be weakened because of over exposure to higher levels of the chemical bisphenol A (BPA). BPA is believed to affect the human hormones.
It is used to make many types of plastics and other consumer products.
When the levels of triclosan and BPA in the urine were compared with cytomegalovirus (CMV) antibody levels and diagnosis of allergies or hay fever in adults and children over age 6 years, it was found that people over 18 years who were over exposed BPA had higher levels of CMV antibody. This finding suggests that their cell-mediated immune system may not be functioning properly. This triclosan finding among the younger children and teenagers may support the hygiene hypothesis
