Etymology: "Rehydrated" is simply "rehydrate" with the past-tense ending "-ed", so the history belongs to the verb itself. "Rehydrate" is built from three parts: the prefix "re-" meaning "again" or "back", the Greek-derived "hydr-" meaning "water", and the verb ending "-ate". "Hydr-" comes from the Greek "hydor", "water", which also gives us "hydrant", "dehydrate" and "hydrogen", a name meaning "water-former" coined in the 1780s. "Rehydrate" was formed in English from those parts, and it is a modern coinage rather than a classical word. Its counterpart "dehydrate" is recorded from the 1800s, and "rehydrate" followed it, becoming common in the twentieth century, especially in food science and medicine, where it describes restoring fluid to dried foods or to patients who have lost water through illness.
