Greater contact with pets from children reduces the risk of allergies



that relationship between children and pets He tends to divide water: some like children who come into contact with animals from a young age, while others prefer to avoid it (at least temporarily). A new study can give a scientific argument to one position.

Researchers from the University of Gothenburg, Sweden, analyzed the relationship between children and allergies and found a pattern: Greater contact with pets from children reduces the risk of allergies, eczema, or asthma. So far, there have been studies that suggest this relationship but with animals. This working group wonders if this will change by taking a few.

Thus, they analyzed information from the work of previous colleagues and observed that, indeed, the number of pets was relevant. According to results published in the scientific journal PLoS ONE, in the first study they reviewed allergy events fell from 43% in boys who had spent their first year with pets at home to 24% in those living with three -And two who live with five don't develop them-.

In the second work, the same benefits are proven: after eight or nine years, those who share their first childhood with pets have a 48% risk of having allergies, while the number drops to 21% in those who are exposed to two or more.

"A dog or cat that is rarely at home or in contact with children may not have a protective effect," said Bill Hesselmar, one of the authors of the article, because an explanation for this relationship had never been seen before. As for the reason, The researchers hypothesize that maybe pets have microbes that stimulate the children's immune system and hence avoid allergies. In this case, he clarified that spending time outdoors from a young age, as well as contact with other children, also seemed to have a protective effect.
