OverExposure to antibacterial soaps affects Immunity

Researchers suggests a new finding that being too clean can actually make people sick. The study collected required data from the survey conducted in 2003-06 by National Health & Nutrition Examination Survey in America. some microorganisms are beneficial for the proper development of our immune system but living in very clean & hygienic environments impacts our exposure to these microorganisms.

Overexposure of children & teenagers to antibacterial soaps that contain the chemical triclosan were more likely to be diagnosed with hay fever & other allergies. Triclosan is an antimicrobial agent. It is widely used in products such as antibacterial soaps, toothpaste, medical devices & 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 & other consumer products. When the levels of triclosan & BPA in the urine were compared with cytomegalovirus (CMV) antibody levels & diagnosis of allergies or hay fever in adults & children o'er age 6 years, it was found that people o'er 18 years who were o'er 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 & teenagers may support the hygiene hypothesis.  To promote this post please click here...
