Did you know there is a disease called “hyponatremia”, where people have too little salt in their blood, it can actually kill people
From Wiki:hyponatraemia (British English) is a reduction in the salt level in the blood. In the vast majority of cases, it is caused by drinking too much water, resulting in an electrolyte disturbance in which the sodium ion concentration in the blood plasma is lower than normal.......Many conditions including congestive heart failure, liver failure, kidney failure and pneumonia can have an associated hyponatremia.
