What is the Hygiene Hypothesis?

Researchers are increasingly looking for answers as allergic diseases continue to rise in the population. The predominant explanation, coined the “hygiene hypothesis” by Professor David Strachan in 1989, states that a lack of early childhood exposure to microbes and other infectious agents increases susceptibility to allergic diseases by suppressing the natural development of the immune system. The idea was widely reported by the media that developed societies, like the United States, have become “too clean”.
