According to preliminary research, quenching of thirst – the homeostatic mechanism to stop drinking – occurs via two neural phases: a "preabsorptive" phase which signals quenched thirst many minutes before fluid is absorbed from the stomach and distributed to the body via the circulation, and a "postabsorptive" phase which is regulated by ...
Adipsia, also known as hypodipsia, is a symptom of inappropriately decreased or absent feelings of thirst. [ 1 ] [ 2 ] It involves an increased osmolality or concentration of solute in the urine, which stimulates secretion of antidiuretic hormone (ADH) from the hypothalamus to the kidneys.
A fluid or water deprivation test is a medical test [1] which can be used to determine whether the patient has diabetes insipidus as opposed to other causes of polydipsia (a condition of excessive thirst that causes an excessive intake of water). The patient is required, for a prolonged period, to forgo intake of water completely, to determine ...

The authors defined a body's need for hydration prior to the onset of thirst and the false sense that the immediate thirst was quenched with the first intake of fluid. To avoid the thirst trap, the authors suggested further intake of fluids even though the body's "thirsty message" had been sated. [9]
During this step, the part is submerged into some kind of quenching fluid; different quenching fluids can have a significant effect on the final characteristics of a quenched part. Water is one of the most efficient quenching media where maximum hardness is desired, but there is a small chance that it may cause distortion and tiny cracking.
Plain water restores only the volume of the blood plasma, inhibiting the thirst mechanism before solute levels can be replenished. [42] Consumption of solid foods can also contribute to hydration. It is estimated approximately 22% of American water intake comes from food. [ 43 ]
Tulare Lake, Owens Lake, Mono Lake and other bodies of water remind us of California's past — and that, ultimately, nature is in charge around here. Cities' thirst nearly killed these California ...
