He picked his nose — he remained a fool: an unpleasant habit can lead to dementiaBy Pictolic https://pictolic.com/en/article/he-picked-his-nose-he-remained-a-fool-an-unpleasant-habit-can-lead-to-dementia
The habit of picking your nose is hardly pleasant. As it turned out, it is not only disgusting, but also dangerous. Scientists have found a relationship between nose picking and Alzheimer's disease. It turns out that active "activity" in the nose area leads to infection with pathogenic bacteria affecting the brain.
A nerve passes between the nasal cavity and the brain, which can become a real gateway for infection. It can be dozens of different microbes, most of which are not dangerous. But some, for example, chlamydia pneumonia, are detrimental to the brain.
Noticing the appearance of foreign microorganisms, the brain protects itself by secreting amyloid protein. It is he, according to doctors, who causes the development of Alzheimer's disease. A dangerous disease falls on fans of picking their nose not instantly, but after a while. For many years, science has not seen a connection between a bad habit and a dangerous disease, but now we are warned!
In addition to sticking fingers in the nose, dementia can be the result of overly thorough, but improper self-care. Studies have shown that another reason for the penetration of chlamydia pneumonia into the brain is the plucking of hairs in the nostrils. After that, microtrauma remains in the nose, through which the infection penetrates into the brain.
A healthy person's nose develops its own microbiome — a community of microorganisms. Nasal mucus containing enzymes and antibodies protects the mucosa from infections. It is produced by goblet-shaped epithelial cells of the nasal passages.
It's not difficult to disrupt the microbiome. This is exactly what happens with a runny nose, which everyone is probably familiar with. But some bacteria are successfully defeated by the microflora of the nose, and some pass on and cause more serious diseases.
In order not to put yourself in danger, doctors recommend carrying out all manipulations in the nose exclusively with sterile instruments. As for hair removal, it needs to be done with a special trimmer, cutting, not pulling out the hair.
