The idea of a link between parasite infection and immune disorders was first suggested in 1968 [13] before the advent of large scale DNA sequencing techniques.The original formulation of the hygiene hypothesis dates from 1989, when David Strachan proposed that lower incidence of infection in early childhood could be an explanation for the rise in allergic diseases such as asthma and hay fever ...
The Hygiene hypothesis postulates that decreasing exposure to pathogens and other microorganisms results in an increase of autoimmune diseases, according to Rook. [17] This theory and the theory that certain parasitic worms pacify the immune response are similar in that both theories attribute the recent rise of autoimmune diseases to the ...
A reaction to an excessive desire for a germ-free environment began around 1989, when David Strachan put forth the "hygiene hypothesis" in the British Medical Journal. This hypothesis holds that environmental microbes help develop the human immune system; the fewer germs people are exposed to in early childhood, the more likely they are to ...

Environmental factors are also thought to play a role in the development of atopy, and the 'hygiene hypothesis' is one of the models that may explain the steep rise in the incidence of atopic diseases, though this hypothesis is incomplete and in some cases, contradictory to findings. [4]
Antonin (Maxim Gaudette, “Polytechnique”) stands in lovely grass fields and proclaims his dissent. The world, embodied by the three women in his life, want him to buckle under, get a decent ...
A new research study has found an association between the affluence of a country, hygiene conditions and the prevalence of Alzheimer in their population. According to the Hygiene Hypothesis, affluent countries with more urbanized and industrialized areas have better hygiene, better sanitation, clean water and improved access to antibiotics. [52]
Epidemiological data support the hygiene hypothesis. Studies have shown that various immunological and autoimmune diseases are much less common in the developing world than the industrialized world, and that immigrants to the industrialized world from the developing world increasingly develop immunological disorders in relation to the length of ...
