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 ...
Low hygiene + low motivation: This is the worst situation where employees are not motivated and have many complaints. Unlike Maslow , who offered little data to support his ideas, Herzberg and others have presented considerable empirical evidence to confirm the motivation-hygiene theory, although their work has been criticized on methodological ...

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 ...

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.
