Hygiene and Diabetes?
Researchers at the University of Helsinki Children’s Hospital believe the rise in auto-immune diseases, like type 1 diabetes and allergies, may be linked to a corresponding rise in hygiene standards. The so-called “hygiene hypothesis” suggests that less bacterial exposure during childhood may hinder the development of a child’s immune system. The researchers point out that Finland has the highest incidence of type 1 diabetes in the world but neighboring countries with lower hygiene stands have much lower reports of the auto-immune disease.
