Zymna Voda was mentioned in 1427 as in Zympnewody. The village initially belonged to the
Ruthenian Voivodeship of the
Polish-Lithuanian Commonwealth and was ethnically Polish as early as the Middle Ages. The names of the inhabitants were also predominantly Polish in the historical sources. After the
Polish–Ukrainian War ended in 1919, Zimna Woda became part of the
Second Polish Republic. In 1921 the municipality had 144 houses with 819 inhabitants, of which 813 were Poles, 6 Germans, 720 Roman Catholics, 24 Greek Catholics, 53 Protestants, and 22 Jews (religion). During
World War II, it first belonged to the Soviet Union and in 1941 to the
General Government, from 1945 again to the
Soviet Union via
Ukrainian SSR. On 18 July 1946, the place was renamed Vodiane (Водяне) and on 18 December 1990, its name was reverted back to Zymna Voda. Until 18 July 2020, Zymna Voda belonged to
Pustomyty Raion. The raion was abolished in July 2020 as part of the administrative reform of Ukraine, which reduced the number of raions of Lviv Oblast to seven. ==Demographics==
