Because your kidneys can filter out a certain percentage of salt, and that's based on the blood concentration

But if your blood goes above the level where the water is being drawn out of your cells and drying them out, you'll be dehydrated from the inside out

Why

[–] elvith@feddit.org 27 points 2 days ago (1 children)

Salt is hydrophile, which means it attracts water.

To much salt (outside cell) now attracts the water in the cell to the outside -> less water in cell, cell dehydrated.
To little salt (outside cell): salt in cell attracts water from the outside, but now salt levels in the cell are diluted (these are actually needed in your cell to function).
Just the right amount of salt: cells can now directly use the water without diluting the salts they contain and continue working as normal

Why?

[–] funkless_eck@sh.itjust.works 4 points 2 days ago

because salt and water happen to be composed in such a way that they fit together nicely, and salt attracts the water in a similar way to a magnet. The positive and negative charges of the salt ions (Sodium+, Chloride–) fit into and attract the opposite charges of the water ions (Hydrogen–, Oxygen+).

It's simple homeostasis, homeslice!

I felt bad for the interviewer at first, until the guy really got into his explanation. He wasn't being a dick, he was just saying "why" is a really deep question.

Yeah he does start out a bit blunt thankfully it had a point.
