While there are still uncertainties regarding the exact cause of allergies, the hygiene hypothesis
theory looks at how increased levels of hygiene and the overuse of antibiotics may affect allergies, explained Tipper.
According to a research hypothesis called the hygiene hypothesis
, the newborn baby's immune system in this way learns to distinguish between its own harmless molecules and foreign molecules.
According to Mroueh, children nowadays were developing more allergies and he put this down to the controversial hygiene hypothesis
, which suggests children are growing more susceptible to allergies due to lack of exposure to infectious agents.
The findings represent a microbial twist in the hygiene hypothesis
, which argues that a less-than-sanitary early life may prime a child's immune system against overreacting to grass, dust mites and other ordinary substances.
The hygiene hypothesis
is the reason investigators are heading down this path.
The hygiene hypothesis
was introduced in 1989 by Strachan, who noted that a reduction in childhood infections might have led to an increase in adulthood allergies.
Knowing what I know about the hygiene hypothesis
, I think twice before I run to a physician for an antibiotic," she says.
This further advances the hygiene hypothesis
that early childhood exposure to microorganisms affects the immune system's development and onset of allergies," said Christine Cole Johnson, Ph.
The IFH report, entitled 'The hygiene hypothesis
and its implications for home hygiene, lifestyle and public health', reviewed evidence that has come to light over the last 20 years, since the 'hygiene hypothesis
' was first proposed.
Alternately, the hygiene hypothesis
posits that the modern obsession with cleanliness is as much a problem as house dust mites.
Thirteen contributions from authors directly involved in the original investigations report on such topics as the hygiene hypothesis
revisited, loss-of-function mutations within the filaggrin gene, the antimicrobial skin barrier, defective sweating responses, the role of cytokines/chemokines in pathogenesis, biomarkers for itch and disease severity, and practical issues on interpretation of scoring systems, among other topics.
One common theory is the hygiene hypothesis
, which posits that excessive hygiene is responsible for the increase of allergies and other immune-mediated diseases.
