You can be too clean

RatIn a study conducted at Duke University in Durham, N.C., laboratory rats were found to be likely to become ill than rats found in the wild. They think this gives credence to the idea that modern society may be too focused on hygiene.

Industrialized societies that emphasize hygiene have higher rates of allergy, asthma and autoimmune diseases such as rheumatoid arthritis compared to the developing world.

Stimulating the immune cells of wild rodents made no difference, but lab rats overreacted, the team reports in the Scandinavian Journal of Immunology.

The wild rodents also showed as much as four times higher levels of immunoglobulins related to allergy and autoimmune disease, but didn’t get sick. (Source: CBC)
