#hydration

• Acrolein — A volatile, colorless or yellowish liquid with an extremely pungent, suffocating, and tear-inducing odor, with the chemical formula CH2=CH-CHO; propenal. It is a highly toxic unsaturated aldehyde formed by the dehydration of glycerol.
• Watering — The act of watering animals and its result; the household or zootechnical process of providing the necessary drinking water to domestic animals (cattle, horses, sheep) to maintain health and productive performance. In a broad sense, the term also designates the entirety of livestock hydration operations at troughs, wells, or automated systems.
• Adipsia — An abnormal diminution, total absence, or loss of the sensation of thirst, manifested even under conditions of severe dehydration of the body. This structural clinical phenomenon is usually caused by lesions located within the anterior hypothalamus (the thirst center), secondary to tumors, head traumas, strokes, or congenital disorders, posing a major vital risk.
• Alcalia — A well-known brand of natural still mineral water, recognized in the market for its strongly alkaline character, featuring a high natural pH (typically around 9.36). It originates from a deep underground spring and is marketed within the context of a healthy lifestyle for its ability to support efficient hydration and help maintain the body's acid-base balance.
• Anadipsia — An intense, excessive, and pathological sensation of thirst, structurally manifested by an urgent and continuous need to consume liquids; it represents an acute or extreme form of polydipsia clinically encountered in severe febrile states, massive dehydration, decompensated diabetes mellitus, or after the ingestion of highly osmotic substances. This symptom indicates a profound hydro-electrolytic imbalance in the body, triggered by the stimulation of osmoreceptor centers in the hypothalamus.
• Anhydride — An organic or inorganic chemical compound formed by eliminating a water molecule from an acid or, less frequently, from an alcohol. Structurally, acid anhydrides react rapidly with water to regenerate their parent acid, being widely used in industrial synthesis, the manufacturing of plastics, pharmaceuticals, dyes, and as acylating agents in research laboratories.
