Cleanliness is next to godliness, but is it possible to have too much of a good thing? For several decades, immunological diseases -- such as hay fever, asthma, diabetes and multiple sclerosis – have been increasing in developed countries, but are uncommon in many undeveloped regions. Medical researcher Joel Weinstock theorizes that modern life is too clean – by scrupulously avoiding dirt, bugs and germs, our immune systems don’t develop properly, leading to the diseases listed above. Weinstock goes so far as to speculate that exposure to hookworm, pinworm, and other intestinal parasites may have been the trigger necessary for developing a healthy immune system. As these parasites have been eradicated, immunological diseases have skyrocketed.

The theory is currently being tested in the lab. Weinstock doesn’t advocate the return of worm infestations. But he does think that getting your hands dirty once in a while can help keep your body in balance.
