Subsequent developments
In November 1881, the British Medical Journal noted that hydropathy was a specific instance, or "particular case", of general principles of thermodynamics. That is, "the application of heat and cold in general", as it applies to physiology, mediated by hydropathy. In 1883, another writer stated "Not, be it observed, that hydropathy is a water treatment after all, but that water is the medium for the application of heat and cold to the body".

Hydrotherapy was used to treat people with mental illness in the 19th and 20th centuries and before World War II, various forms of hydrotherapy were used to treat alcoholism. The basic text of the Alcoholics Anonymous fellowship, Alcoholics Anonymous, reports that A.A. co-founder Bill Wilson was treated by hydrotherapy for his alcoholism in the early 1930s.
