Salt is essential for human life, and saltiness is one of the basic human tastes.

Let’s follow salt into the digestive framework and see what happens. In the mass of the small digestive tract, the salt is ingested into your circulation system, making your blood saltier than it was  before.

Charles planted himself on the sofa, looked at the b-ball game on his living room TV and pulled the coffee table. The reason? That is the place he had set the hot, fresh pizza that had just been delivered.

He opened the top and went after a slice, its covering twisting under the weight of pepperoni, ham, bacon and wiener, and sprinkled a little salt on top for good measure before digging in. Six slices later, Charles was full to the gills — and unbelievably thirsty.


From the cured meats to the extra sprinkle, Charles had recently ingested an unbelievable measure of salt, and his body started making adjustments to handle it. The salt going through the wall of his small intestine was entering his circulation system and making the salt content in his blood rise.

As saltier-than-ordinary blood zooms through veins and arteries, the body senses an imbalance. At the point when there’s more salt in the fluid surrounding the cells than in the cells themselves, the sodium-rich fluid attempts to pull even more fluid out of the cells. It’s a condition known as hypernatremia, and it’s a warning that sends the cells’ chemical messengers rushing to the brain to report the high salt levels in the fluid around the cells and criticize their potential dehydration.

“Water! Water! Water!” signals the brain and — voila! — you’re thirsty.
