No, your clean home isn’t messing with your immune system.This is the reason

Sometimes useless (or simply wrong) health advice pierces our brains.For example, you don’t have to Drink 8 glasses of water If you have fructose intolerance, apples may not be able to keep the doctor away every day, and every day. But what about over-sterilized homes that ruin our immune system?

I was revealed time And once again, This misinterpretation of’Hygiene hypothesis‘Stuck in our group Consciousness.. Now, British researchers have published a treatise that systematically rejects the idea that we are too clean for our own benefit.

“For more than 20 years, there has been a public story that hand and household hygiene practices, which are essential to stop exposure to disease-causing pathogens, also prevent exposure to beneficial organisms.” Graham Luke said, Lead Author and University College London Microbiologist.

“This treatise coordinates the apparent conflict between the need for cleansing and hygiene to protect us from pathogens and the need for microbial input to live in the gut and set up the immune and metabolic systems. I started to do that. “

Researchers emphasize that microbes are very important to us. Our entire body, including the intestines, skin and lungs, needs them for us to keep running effectively.

The hygiene hypothesis concerns early childhood exposure to certain microorganisms that have co-evolved with humans to support the development of a powerful immune system, especially with respect to allergies and other immune disorders.

Even if you don’t wash your hands before eating, you can’t improve your immune system. That means you are more likely to have gastroenteritis. (However, it is important to note that the choice of cleaning product allows you to: Propagate harder microorganismsSo it’s best to stick with regular soap. )

In a new treatise, a review of previous literature, the team places four specific nails in the casket for the maxim that “a clean house is immune-poor.”

First, babies and children develop their own small microbial system, first sown by the mother and then primarily by the family and their environment.Microorganisms from individuals are washed away and mixed to create a specific one Household microbial flora It is mainly shared by people living together (including pets).

“Our mother, family, natural environment, and exposure to vaccines can provide all the microbial inputs we need.” Luke said.

“These exposures are consistent with intelligently targeted hygiene or cleaning.”

Second, vaccines are surprisingly good at stimulating the immune system in fact, as well as potentially deadly illnesses.

“In the 1980s, live measles vaccination in Africa began to be reported to reduce overall child mortality to a extent that could not be explained by measles incidence itself.” The team wrote.

“The non-specific effects of the vaccine are similar to the non-specific survival benefits seen after recovery from the corresponding infection.”

Third, we are now well aware that outdoor exposure is important to help us. Develop a strong immune system..But no one is cleaning the great outdoors, and the team notes that the natural bacterial profile is completely different from yours Anyway, find it indoors.

“Exposing children from the natural environment to biodiversity in school playgrounds increased immunomodulatory peripheral blood biomarkers.” The team wrote in their treatise.

“Therefore, evolutionary and epidemiological considerations give the view that children need to be exposed to the microbial flora of the natural environment, rather than the unnatural microbial flora of modern buildings.”

Finally, this last point is not yet definitive, but the team said that if there are health problems associated with a clean environment, it may not be the removal of the organism that is causing the health problems. thinking about. The harsh cleaning agent used.

Teams, targeting our cleaning may help limit these types of problems, as well as exposure to the types of microorganisms that can make us sick. It suggests that there is no.

“Therefore, home cleaning is good and personal cleanliness is good, but as detailed in the treatise, targeting the hands and surfaces most often involved in the transmission of the infection to prevent the spread of the infection. need to do it.” Luke said..

“By targeting our cleaning methods, we also limit children’s direct exposure to cleaning agents.”

The review is published in Journal of Allergy and Clinical Immunology..
