"Do not wash the pacifier so much when it falls to the ground! Let the child

get stained, that is how he is immunized!

", Said the grandmothers in the times when the coronavirus had not yet changed our lives. His theory, that with our obsession with cleanliness we were raising children in a kind of bubble that would inevitably

lead

them

to have a weak immune system

, has just been dismantled in 'Microbial exposures that establish immunoregulation are compatible with specific hygiene ', research carried out by experts from UCL and the London School of Hygiene and Tropical Medicine.

"For more than 20 years, there has been a public narrative that domestic and hand hygiene practices - essential for stopping exposure to disease-causing pathogens - are also

blocking exposure to beneficial organisms

," says lead author. of this study, published in the 'Journal of Allergy and Clinical Immunology' in late May this year.

According to this widespread hypothesis, exposure, during the first years of life,

to certain microorganisms would protect us when we reach adulthood

, an argument that these researchers have now just calibrated.

"In this document, we set out to reconcile the apparent conflict between the

need for cleanliness and hygiene

to keep us free of pathogens and the

need for microbial inputs

to populate our guts and thus configure our immune and metabolic systems."

In this review of the evidence, the researchers point to

four

key

factors

in understanding that, although some may believe it, we haven't gotten too clean.

First, the

microorganisms found in a modern home

are largely the only ones we need to

achieve the immunity

that exposure to certain microbes provides.

Second, (and this is especially aimed at anti-

vaccines

),

vaccines

, in addition to protecting us against the infections they fight, do even much more to

strengthen our immune system

.

Third, the researchers note that there is now more concrete evidence that microorganisms in

the natural green environment

are particularly important to our health.

And finally, he assures that, when epidemiologists find an association between cleaning the home and health problems such as allergies, these are not usually due to the elimination of organisms, but rather to the

exposure of the lungs to products

that favor development. of allergic responses.

Conclution?

"Both cleaning the house and taking care of personal hygiene is good, but, as we explained in some detail in the document, to avoid the spread of infections, we must

focus on the hands and surfaces most frequently involved in transmissions

. In this way, by focusing our practices, we will also limit the direct exposure of children to the

agents of cleaning products,

"recommends Professor Rook.
