People overexposed to antibacterial soaps with Triclosan (present in soaps, toothpastes, pens, diaper bags and medical devices), may suffer a greater number of allergies. In addition, the Bisphenol-A or BPA , present in many important plastics and plastic additives, can negatively influence the immune system. The above was revealed by a study of the School of Public Health of the University of Michigan, in the United States .
The two mentioned compounds belong to a certain class of environmental toxins that cause endocrine disorders since they mimic or affect the hormones .
The researchers based the study on data from the National Survey of Health and Nutrition Exam 2003-2006, from their region, and concentrated their attention on the comparison with Separate bookmarks of alterations of the immunity system, the presence of BPA and triclosan in the urine of people
It was deduced that people older than 18 years with high levels of exposure to Bisphenol A had higher levels of antibodies, which indicates that their system of immunity mediated by cells may not be functioning properly.
The experts also determined that people older than 18 years and with higher levels of Triclosan were more prone to allergies and hay fever diagnoses.
In the case of Bisphenol A, the results indicated, age is important, since in people older than 18 years the highest volumes of the compound appeared linked with higher levels of reaction.
But in the youngest, the opposite occurs, which suggests that the time of exposure, the amount and duration of exposure can affect the response of the immunity system.
"Life in very clean and hygienic environments can impact our exposure to microorganisms that are beneficial for the development of the immunity system," said the study's principal investigator, Allison Aiello, a professor at the University.
