Getting dirty helps a child's skin heal from cuts and inflammations.

In the latest confirmation of the "hygiene hypothesis," which states that exposure to different kinds of germs during childhood helps the body fight off allergies and other aliments, researchers at University of California at San Diego discovered that otherwise harmless bacteria found in dirt interrupts the process of skin inflammation.
