How bad would it be to inject seawater into your bloodstream? - Lemmy.World

I did some light research and asked AI, which said it would be extremely dangerous. But come on, it wouldn’t be that dangerous, right? We evolved from animals that lived in the ocean.

Bacteria… Does one really need to say ANYTHING else?
I mean, ocean life seems to deal with the massive amount of bacteria somehow?

Mostly harmless.

The salt is far more of a problem.

Then what is saline made up of??

Salt is fine, it is bacteria that will fuck you up.

Isn’t it just the concentration that’s off? 3.5% vs 0.9%?

It sounds like there’s special compositions sometimes, which are supposed to be more healing - I was given Ringer’s lactate a bit ago - but that the default is literally just salt and pure water at that magic 0.9%.

The bacteria in seawater are generally going to be the kind that like seawater, not people. Unless someone dumped sewage nearby…

The living nasties to be aware of are more parasitic worms like swimmer’s itch and toxic algaes, and unless you’re very unlucky with the algae concentration, neither are a pressing problem in the context that you have concentrated salt water spreading up a damn limb.

I do wonder if the average amount of microplastics by volume in your body would increase or decrease
