Clean harmful to your health?

Children sometimes useful dirty, because that excessive cleanliness damages the skin, according to U.S. researchers. The skin live bacteria that are able to prevent inflammation, they do not give the body too rapidly to react to stimuli, explains the television and radio BBC. Thus, to kill these harmful bacteria.

This finding confirms pre-existing “hygiene hypothesis”: it states that contact with bacteria in early childhood in the future does not develop different types of allergies. It has long been a belief that because of our concerns about cleanliness in the developed world has recently become much more allergies.

Researchers from the Institute of Medicine, University of California at San Diego found that the widespread bacterium-negative staphylococci can affect the skin cells and block the inflammation, not allowing the body to react too strongly to the injured. The findings are published in the online edition of Nature Medicine.

“A notable achievement of our work lies in the fact that she gave a molecular explanation of the hygiene hypothesis and discovered previously unknown elements of healing, – says head of research group of Professor Richard Gello. – This may enable us to develop new approaches to treatment of diseases associated with skin inflammation.

In support of scientists have already made some parents. Group Parents Outloud said that experts have brought theoretical justification for its campaign against the education of children under greenhouse conditions. Representative of the British organization of Allergy UK said that recently there is growing evidence of benefit from contact with microbes, but this issue needs further study.

“Over the past ten years in the UK was three times more allergenic. Every third are allergic to something – she said. – Some cases may be due to the fact that people are better informed. But for the most part the cause of genetics and environmental conditions .
