Man has moved rapidly from the hunter-gatherer environment to the living conditions of the rich industrialised countries. The hygiene hypothesis suggests that the resulting changed and reduced pattern of exposure to micro-organisms has led to disordered regulation of the immune system, and hence to increases in certain chronic inflammatory disorders. The concept began with the allergic disorders, but there are now good reasons for extending it to autoimmunity, inflammatory bowel disease, atherosclerosis, depression associated with raised inflammatory cytokines, some cancers and perhaps...

This edited collection of 12 chapters by research workers from a wide range of disciplines resolves the confusion that currently surrounds the “hygiene hypothesis” by considering the human need for exposure to microorganisms from an evolutionary point of view. The book explains why we evolved a requirement for exposure to microbiota from our mothers, from other people, and from the natural environment. It also explains the physiological roles of these exposures, what goes wrong when the exposures are distorted and how human lifestyles and activities, including degradation of the natural...
