According to the “hygiene hypothesis,” the problem with extremely clean environments is that they fail to provide the necessary exposure to germs required to “educate” the immune system so it can learn to launch its defense responses to infectious organisms.
What is the hygiene hypothesis theory?
The hygiene hypothesis proposes that childhood exposure to germs and certain infections helps the immune system develop. This teaches the body to differentiate harmless substances from the harmful substances that trigger asthma. In theory, exposure to certain germs teaches the immune system not to overreact.
How does the hygiene hypothesis serve as an explanation for an increase in allergies seen in humans today?
The hygiene hypothesis proposes that the stimulation of the immune system by microbes protects from the development of inflammatory diseases; therefore a reduced exposure to infectious agents may explain the rise in allergic and autoimmune diseases in industrialized countries (Yazdanbakhsh and Matricardi, 2004).
