why do our bodies crave salt?

Answer 1

We need sodium and chloride (NaCl, or sodium chloride is the most common form of salt) for many things in our body. for one thing, we use sodium in our nerves to fire "action potentials", to communicate with other parts of our bodies. Most things in the body have to have relatively even positive and negative charges; since sodium is positive, we need chloride (which is negative) to keep things even. We keep these ions (charged particles) in relatively high concentration in the extracellular fluid, so there is less osmotic movement of water.

Answer 2

Because salt is an important electrolyte in the body. For example, the depolarization of the myocardium (heart) is based on the influx of sodium ions. This is why patients with high blood pressure are placed on a salt restricted diet.

Answer 3

Because the body excreets/loses salt by way of sweat, urine, and digestion. The body craves to replensih salt to maitain its natural chemical balance.
