🤣🤣🤣🤣🤣🤣 the so called “hygiene hypothesis” was debunked ages ago. It’s not real science. At all. It’s a bit like the “science” of tobacco companies that found smoking improved lung function, reduced asthma attacks, and is definitely not linked to cancer.

”That “hygiene hypothesis,” first proposed in 1989 (3), has become enshrined in popular culture: We’re too clean for our own good. It’s a straightforward, compelling idea. And many scientists are eager to see it thrown out.
“We know an awful lot now about why our immune system’s regulation is not in terribly good shape, and it’s got absolutely nothing to do with hygiene,” says Graham Rook, an emeritus professor of medical microbiology at University College London. Today, epidemiological, experimental, and molecular evidence support a different hypothesis: Early exposure to a diverse range of “friendly” microbes—not infectious pathogens—is necessary to train the human immune system to react appropriately to stimuli. If this new hypothesis is true, then cutting back on personal hygiene will not have an impact on rates of chronic inflammatory and allergic disorders; it will, however, increase infections. The hygiene hypothesis is a “dangerous misnomer which is misleading people away from finding the true causes of these rises in allergic disease,” says Sally Bloomfield, chair of the International Scientific Forum on Home Hygiene and an honorary professor at the London School of Hygiene and Tropical Medicine. “I’ve even seen things in the media saying we shouldn’t wash our hands. What the hell are they talking about?””
The hygiene hypothesis is out of date and is undermining public health

Researchers are concerned that attitudes to hygiene are being undermined by the hygiene hypothesis, and that this misleading misnomer could contribute to the spread of infectious disease.
Scientists debunk idea that rise in allergic diseases is due to homes becoming “too clean”

”UK researchers say that they have dismantled the “myth” that allergic diseases have risen to epidemic levels because people now live in sterile homes and have become “too clean.” A report published today by the International Scientific Forum on Home Hygiene rejects the so called hygiene hypothesis, which first suggested more than 20 years ago that reduced exposure to infection in early childhood as a result of improved cleanliness might explain the rise of some allergies.1 Not only is the theory unsupported by evidence, says the report, it is “confusing and potentially dangerous” because it could put people off washing and cleaning to remove possible pathogens when the threat of infectious disease is rising.”
No, Your Clean Home Isn't Messing With Your Immune System. Here's Why

“Sometimes unhelpful (or just plain wrong) health advice sticks in our brains. For example, you don't necessarily need to drink eight glasses of water every day, and an apple a day may not keep the doctor away if you have fructose intolerance. But what about overly sanitized homes ruining our immune systems? Although it's been debunked time and time again, this incorrect interpretation of the 'hygiene hypothesis' has stuck around in our collective consciousness. Now, researchers in the UK have published a paper systematically rejecting the idea that we're just too clean for our own good.“
