Why it's not good to drink sugary sodas when we're thirsty

The need to ingest fluids is controlled by a region of the diencephalon, responsible for controlling the regime of fluids in our body.

One of them measures the tension present in the walls of the heart that informs about the volume of blood circulation. Another measures the proportion of dissolved salts in the blood.
