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 ...
Since the germ theory of disease, cleanliness has come to mean an effort to remove germs and other hazardous materials.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.
Background Chlorine and caustic soda are produced at chlor-alkali plants using mercury cells or the increasingly popular membrane technology that is mercury free and more energy-
The hygiene hypothesis, a concept initially theorized by immunologists and epidemiologists, has been proved to have a strong connection with evolutionary mismatch through recent studies. The hygiene hypothesis states that the profound increase in allergies, autoimmune diseases , and some other chronic inflammatory diseases is related to the ...
The hygiene hypothesis attempts to explain the increased rates of asthma worldwide as a direct and unintended result of reduced exposure, during childhood, to non-pathogenic bacteria and viruses. [ 67 ] [ 68 ] It has been proposed that the reduced exposure to bacteria and viruses is due, in part, to increased cleanliness and decreased family ...

This gives rise to a new slant on the hygiene hypothesis theory—that co-evolution of humans and parasites has led to an immune system that functions correctly only in the presence of the parasites. Without them, the immune system becomes unbalanced and oversensitive.
