Thirst
Thirst is the craving for fluids, resulting in the basic instinct of animals to drink. It is an essential mechanism involved in fluid balance. It arises from a lack of fluids and/or an increase in the concentration of certain osmolites, such as salt. If the water volume of the body falls below a certain threshold or the osmolite concentration becomes too high, the brain signals thirst.

Famous quotes containing the word thirst:
“While yet it is cold January, and snow and ice are thick and solid, the prudent landlord comes from the village to get ice to cool his summer drink; impressively, even pathetically, wise, to foresee the heat and thirst of July now in January,—wearing a thick coat and mittens! when so many things are not provided for. It may be that he lays up no treasures in this world which will cool his summer drink in the next.”
—Henry David Thoreau (1817–1862)
“To ask strength not to express itself as strength, not to be a will to dominate, a will to subjugate, a will to become master, a thirst for enemies and obstacles and triumphant celebrations, is just as absurd as to ask weakness to express itself as strength.”
—Friedrich Nietzsche (1844–1900)
“Uncontrolled, the hunger and thirst after God may become an obstacle, cutting off the soul from what it desires. If a man would travel far along the mystic road, he must learn to desire God intensely but in stillness, passively and yet with all his heart and mind and strength.”
—Aldous Huxley (1894–1963)
