Daycares in Finland Built a 'Forest Floor', And It Changed Children's Immune Systems

I've always wondered about the wisdom of raising children in a antiseptic sterile environment.

Given that we so successfully evolved through the millennia closely tied to the soil and a diverse environment, suddenly altering that pattern could be counterproductive.

The Fins might be on to something here...



The experiment in Finland is the first to explicitly manipulate a child's urban environment and then test for changes in their micriobiome and, in turn, a child's immune system.

While the findings don't hold all the answers, they do support a leading idea - namely that a change in environmental microbes can relatively easily affect a well-established microbiome in children, giving their immune system a helping hand in the process.

The notion that an environment rich in living things impacts on our immunity is known as the 'biodiversity hypothesis'. Based on that hypothesis, a loss of biodiversity in urban areas could be at least partially responsible for the recent rise in immune-related illnesses.

"The results of this study support the biodiversity hypothesis and the concept that low biodiversity in the modern living environment may lead to an un-educated immune system and consequently increase the prevalence of immune-mediated diseases," the authors write.
