treatments in vogue at that time. Following the introduction of hydrotherapy to the U.S., John Harvey Kellogg employed it at Battle Creek Sanitarium, which opened in 1866, where he strove to improve the scientific foundation for hydrotherapy. Other notable hydropathic centers of the era included the Cleveland Water Cure Establishment, founded in 1848, which operated successfully for two decades, before being sold to an organization which transformed it into an orphanage. At its height, there were over 200 water-cure establishments in the United States, most located in the northeast. Few of these lasted into the postbellum years, although some survived into the 20th century including institutions in Scott (Cortland County), Elmira, Clifton Springs and Dansville. While none were located in Jefferson County, the Oswego Water Cure operated in the city of Oswego. 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. Recent techniques A subset of cryotherapy involves cold water immersion or ice baths, used by physical therapists, sports medicine facilities and rehab clinics. Proponents assert that it results in improved return of blood flow and byproducts of cellular breakdown to the lymphatic system and more efficient recycling. Alternating the temperatures, either in a shower or complementary tanks, combines the use of hot and cold in the same session. Proponents claim improvement in circulatory system and lymphatic drainage. Experimental evidence suggests that contrast hydrotherapy helps to reduce injury in the acute stages by stimulating blood flow and reducing swelling. Society and culture The growth of hydrotherapy, and various forms of hydropathic establishments, resulted in a form of tourism, both in the UK, and in Europe. At least one book listed English, Scottish, Irish and European establishments suitable for
