Apparently there's on average 3.5% salt in seawater, so you could probably drink 1 liter 100 ml daily and be fine assuming you supplement it with something "else". you know what..

    You can't supplement it with your urine, because your urine will be containing the salts you're trying to get rid of.

    If you had an ample supply of urine from someone who was extremely well hydrated, maybe.

    But yeah no you shouldn't be drinking seawater at all, it's just too salty. You're expending more water of get rid of the salt. Coffee or tea would be fine despite slight diuretic effects, but ocean water is just too salty.

    You won't die immediately, but there's no way that consuming 35g salt/day won't lead to severe health issues down the line ...

    35g of salt can be a lethal dose for a human of about 70kg, so no one's going to last too long on this diet.

    LD50 for a human of 70kg is 210g (3g salt per kg of human), so it seems rather unlikely that it will be lethal short-term (though always possible). It mostly becomes lethal when you don't have any water that's actually hydrating.

    I think you may be thinking of the LD50 for rats. People have died from much less than 3g/kg.

    The lethal dose was estimated to be less than 10 g of sodium (<5 teaspoons of salt) in two children, and less than 25 g sodium in four adults (<4 tablespoons of salt).

    https://pmc.ncbi.nlm.nih.gov/articles/PMC5537768/

    An acute toxicity from excess sodium intake with the possibility of fatal outcome has been reported in relation to the ingestion of huge amounts of sodium, such as 0.5–1 g of salt/kg body weight.

    Depends on rest of diet and starting conditions and duration.

    Like if in a highly glycolytic diet/state... severely not advisable to do large doses of salt. But if in ketosis, you've a far higher ceiling. 3.5g's normal. 35g's likely going too far even when in ketosis.
