Best Answer

Basically, the lack of liquids in your body system. Actually.... A rise in plasma osmolality triggers thirst which in turn excites the hypothalamic thirst center. The hypothalamic thirst center neurons are stimulated when their osmoreceptors lose water by osmosis to the hypertonic ECF or are activated by angiotensin II, by baroreceptor inputs, or other stimuli.
