Put your fingers in your noseas well as being an unpleasant gesture for those close to you, it is a risky and harmful practice illnesses.
Research advances the hypothesis that get rid of it nose may play a role in increasing the risk of developing Alzheimer’s disease, a link that experts are taking seriously.
It seems like an absurd idea, but it happens that bacteria and virus present on our fingers can easily enter our body if we stick them in our nose. AND cause serious damage.
Picking your nose? The consequences are much more serious than you think
The olfactory system in the nasal cavity has a direct pathway to brain areas where Alzheimer’s disease wreaks havoc, such as the hippocampus. This, according to research by Western Sydney University in Australia, could lead to Alzheimer’s risks.
“Many possible factors could contribute to the development of Alzheimer’s disease, including amyloid peptide and tau deposition, but more recent evidence suggests that neuroinflammation may also play a role – at least partial – in its pathogenesis,” the researchers write.

As we read in the paper published in Biomolecules, the nose could indirectly lead to brain inflammation: picking means that everything found on the fingertips (such as pathogens) is pushed towards the brain. AND the extraction of material from the nose affects the balance of the microbiome, potentially making it a less effective barrier for the body.
As the researchers note, Picking your nose has already been linked to an increased risk of infection: A study published last year showed a link between this habit and the possibility of contracting COVID-19, for example.

Is picking your nose dangerous?
Other significant indicators highlighted include the fact that some viruses have been regularly found in the brains of people with Alzheimer’s and that signs of Alzheimer’s are often identified first in the olfactory bulb, the part of the brain that detects odors.
We are still a lot far from a definitive conclusion that picking your nose increases the risk of Alzheimer’s, but the signs are there, and as we better understand this complex disease, we can also work on more effective treatments.
In short, better be careful.
