I read damage to the nasal epithelium can allow pathogens to reach the brain:
"New research from Griffith University has shown that damage to the lining inside the nose increases the risk of bacteria sneaking into the brain via nerves, potentially causing long-term health issues." ... "Bacteria and viruses, and resultant neuroinflammation, may even contribute to neurodegenerative disorders, such as Alzheimer's and Parkinson's diseases"

- e40 7y agoI wonder if that means people with seasonal allergies are more likely to have these diseases.
- drusepth 7y agoAlso people that chronically pick their nose.
- loco5niner 7y agoLikely not unless they make it 3 inches in: > "The olfactory epithelium is a specialized epithelial tissue inside the nasal cavity that is involved in smell. In humans, it measures 9 cm2 (3 centimetres by 3 centimetres) and lies on the roof of the nasal cavity about 7 cm above and behind the nostrils."
- onionionion 7y agoPhew, that's a relief

Smear infections are a thing, hence the recommendation to not touch one's face during the SARS-CoV-2 pandemic. On the other hand, nasal crusting is presumably also acts as petri dish. Clearly our nostrils are appropriately sized such that our fingers can fulfill a cleaning function, and this is also observed in other great apes with dry nostrils. Some researcher even suggested digesting dried mucous (read eating it) may be beneficial for the immune system as it allows it to build antibodies to novel viruses: https://en.wikipedia.org/wiki/Dried_nasal_mucus https://en.wikipedia.org/wiki/Dried_nasal_mucus
- everyone 7y agoI wonder why picking ones nose is considered gross (and eating it doubly so). Is it simply a weird quirk of our society? Kids will naturally do it right? Are there examples of other societies where its considered to be fine?
- wkearney99 7y agoA co-worker some years ago described being a missionary in the Philippines. The locals were perplexed at his use of a handkerchief. Their perspective was "why would you want to SAVE it?" Their method being to lean over, hold one nostril and BLOW.
- grawprog 7y agoOr people that imbibe certain substances through their nasal cavities?
- agumonkey 7y agoor both, allergies make you over conscious about nose pipes, sometimes I cannot tolerate any clogging and if tissue forbid me to unclog them I'll maniacally 'find a way'
- anonAndOn 7y agoAlthough rare, amoebas found in untreated water can cause fatal brain infections if they get in your nasal passage[0], via neti-pots or swimming, for example.

- jonny_eh 7y agoSounds like we shouldn't be blowing our nose, shooting more bacteria than in necessary into our nasal cavities.
- softwaredoug 7y agoSo... I should stop picking my nose? Seriously asking
- JohnJamesRambo 7y agoYes, but not for that reason.
- hourislate 7y agoIs it because of the Danger Triangle? If you pluck those hairs, germs and particles near the follicles can get inside and cause an infection. He described the concept of a "danger triangle," or the area on the face between your mouth and nose that's susceptible to passing infections on to the brain. https://www.businessinsider.com/why-you-shouldnt-pluck-your-nose-hairs-2016-7 https://www.businessinsider.com/why-you-shouldnt-pluck-your-...
- JohnJamesRambo 7y agoWell that and it is disgusting.
- Swaglord333 7y agoI read this an hour ago and it is still on my mind. I'm a pathological nose picker and this is some hard deterrent
- catalogia 7y agoI suppose plucking nose hairs should also be avoided.
- arthurcolle 7y agoSo no methyl (1R,2R,3S,5S)-3- (benzoyloxy)-8-methyl-8-azabicyclo[3.2.1] octane-2-carboxylate? Got it, good to know.
