Salt in Our Body

Salt in our body is necessary for life itself. Even our bones and muscles contain salt. Each of us has approximately a heaping teaspoon of salt in our blood. If you sweat, go to the toilet or cry, you lose some of this salt.

In modern medicine, if someone has suffered severe blood loss because of an operation or an accident, an approximately 1% salt solution in water is used to replenish the blood volume.

The reason why can be found in the history of how life developed. The first living creatures millions of years ago were single-celled organisms that lived in the sea. The salty sea water was their habitat, supplying them with nutrients and removing waste products.

Over the course of time, those single-celled organisms developed into larger creatures. Dating back to that time are jelly fish, for example, animals that have actually not evolved much since then.

Then those primitive creatures emerged onto the land and had to adapt to the new living conditions. That said, one of their original characteristics remained: Now as then, their body cells have to be “rinsed” in a salty liquid, continuing to provide vital nutrients and remove harmful waste products.
