It is common knowledge that keeping a clean environment is the best way to prevent the spread of germs. Researchers have suggested that ultra-clean environments however, may not be best for children. This type of environment prevents children from being exposed to common germs. This exposure is needed to ensure the development of an effective immune system later in life.
By constantly using antibacterial soaps and hand sanitizers, parents may be inadvertently inhibiting immune network development in their children. Lead author of the study Thomas McDade states, "our research suggests that ultra-clean, ultra-hygienic environments early in life may contribute to higher levels of inflammation as an adult, which in turn increases risks for a wide range of diseases." The researchers contend that inflammatory systems require greater exposure to bacteria and other microbes for proper development.
