ronigamiHow bad would it be to inject seawater into your bloodstream?
dandelionBut come on, it wouldn’t be that dangerous, right?
🤦♀️ this is some serious /r/WhyWomenLiveLonger/ content
I mean so far the answer seems to be “as long as you dilute it a bit first you’d be fine”
that does not seem to be a reasonable takeaway, bacterial and fungal infections from injecting non-sterile solutions into your body can definitely kill you
hyperfocusing on how dilute the salt would need to be for it not to be dangerous misses a lot of context
Most of this is fairly handwavey without numbers to be fair. But like, this is the reason we have an immune system, right?
does the immune system nullify risk of contracting an illness in other contexts? Certainly not perfectly - and injecting dirty sea water directly puts the bacteria, fungi, and parasites into your bloodstream, bypassing the protective measures your body normally has for keeping that stuff on the outside (like mucus, hair, the acidic environment of the stomach, etc.).
Yeah, you might be able to make ghetto saline with distilled water and the ocean and not become emergently ill, but you shouldn’t actually do it. Even if you collect from an immaculate site and dodge any human (or mammal? This is the kind of weird situation where zoonosis could happen) pathogens, foreign bodies in the bloodstream won’t make you healthier.
I haven’t seen much evidence OP thinks this is a good idea and not just a thought experiment, though. That would be weird.
I wouldn’t want to do that without some significant heat and pressure for an extended period of time, and maybe add some some preservatives for good measure, and honestly I wouldn’t be past using a syringe filter to further purify it - anything that gets injected into my body better be safe, those are crazy risks
