Another Good Reason to Let Your Baby Crawl at Survival of the Sickest: The Book

Scientists at the University of Cincinnati have just published a study in the journal Allergy, showing that exposure to certain indoor microbial elements (specifically something called fungal glucans) at an early age can decrease future wheezing and possibly the development of allergies in children. Infants are often exposed to indoor fungal glucans by crawling on a somewhat dusty floor.
This wonderful interplay between the indoor environment and our immune system is a classic example of evolution at play. Through natural selection, our immune systems were designed, to learn about the world around us and sense the differences between friend and foe (for more on this idea see here). By overusing antimicrobial cleaners or being generally overprotective, we rob our children’s immune systems the important chance to learn these lessons. In an attempt to keep your child healthy you might just be making them sicker.
