- 1補水、補充水分（運動／健康用語；化學「水合」是另一回事）
Hydration is the work of giving a body — or a plant, or soil — enough water so it stays well. After sport, a coach talks about hydration: have you drunk enough? If you have not, you are dehydrated, which is the other side of the same idea. Ads, bottles, and health class use the word a lot now; older everyday English more often just said “drink water.” Nurses still check a patient’s hydration in a careful, medical way. Chemists also use hydration for a tighter meaning (water joining a chemical), but that is not this sense. Here it is about keeping someone or something healthy with water: a runner, skin, a cut flower in a vase. The verb is hydrate; this word is the noun — the act or the state.
From the word’s history
From hydrate + -ion.
hydrate（使水合）加 -ion，指補充水分或水合作用。
組成hydrate + -ion (turns the verb into a noun: the act or the state).
