We are scientists who have researched environmental contaminants – in our homes, in our workplaces, in our gardens – so we have some idea about what exactly you can do when your finger is satisfactorily inserted into your sniffer. What am I jamming there?
Nose picking is a natural habit – children who haven’t yet learned social norms quickly find that the fit between their index finger and nostril is great. But there’s so much more to it than just snot.
Over the course of about 22,000 breathing cycles per day, the mucus that boogers make forms an important biological filter to capture dust and allergens before they enter our airways, where they can cause inflammation, asthma, and other long-term pulmonary issues.
Cells in your nasal passages called goblet cells (named after their cup-like appearance) produce mucus to trap viruses, bacteria, and dust that contains potentially harmful substances such as lead, asbestos and pollen.
Nasal mucus and its antibodies and enzymes are the body’s front-line immune defense system against infection.
The nasal cavity also has its own microbiome. Sometimes these natural populations can be disturbed, leading to various conditions such as rhinitis. But in general, our nasal germs help repel invaders, fighting them off on a mucus battlefield.
The dust, microbes, and allergens that accumulate in your mucus eventually end up in the mucus dripping down your throat.
This is usually not a problem, but it can increase environmental exposure to certain contaminants.
For example, lead—a neurotoxin prevalent in house dust and garden soil—enters children’s bodies most efficiently through ingestion and digestion.
So, if you smell or eat boogers instead of blowing them off, you can especially worsen environmental toxin exposure.
What does science say about the risks of booger-mining?
Golden Staff (staphylococcus aureussometimes shortened s. aureus) is a germ that can cause a variety of mild to severe infections. Studies show that it is most often found in the nose (this is called nasal carriage).
A study has found that piercing the nose is associated with s. aureus Nasal carriage, which means that the nose-lifting role in the nasal carriage may be the cause in some cases. Can help in overcoming the habit of picking nose s. aureus Strategies for liberation from colonialism.
Nose bites may also be associated with an increased risk of golden staph transmission in wounds, where it poses a more serious risk.
Sometimes, antibiotics don’t work on golden staph. Growing antibiotic resistance calls for health care providers to assess patients’ nose picking habits and educate them on effective ways to prevent finger-to-nose practices, a paper says.
The nose raise can also be a vehicle for the transmission of Streptococcus pneumoniaeA common cause of pneumonia among other infections.
In other words, sticking a digit in your nose is a great way to further jam up germs in your body or spread them into your environment with your snorting finger.
There is also a risk of sores and scratches inside the nostrils, which can allow pathogenic bacteria to invade your body. Self-harm through the nose under compulsion is called rhinotylxomania.
Well, I chose. now what?
Some people eat them (the technical term is mucophagy, meaning “mucus feeding”). Besides being disgusting to eat boogers, it also means ingesting all those mucus-bound germs, toxic metals, and environmental contaminants discussed earlier.
Others wipe them at the nearest object, a small gift that can later be discovered by someone else. Gross, and a great way to spread germs.
Some more hygienic people use a tissue for recovery, and then throw it in the trash or toilet.
This is probably at least among the worst options, if you really have to pick your nose. Just make sure you wash your hands extra carefully after blowing or digging in your nose, given that infectious viruses can live on hands and fingers until the mucus dries out completely.
no advice in the world will stop you from digging
Secretly, in the car or on a napkin, we all do it. And truth be told, it’s very satisfying.
But let’s respect the tireless work done by our remarkable nose, mucus, and sinus cavities—such wonderful biological adaptations—and remember that they’re working hard to protect you.
Your sleep is working overtime to keep you healthy, so don’t make it harder by jamming your dirty fingers upward. Don’t be a grub – blow carefully, throw away the tissue thoughtfully, and wash your hands afterward.
