Hydrotherapy in the context of "Balneotherapy"

Franklin D. Roosevelt, who was the president of the United States from 1933 to 1945, began experiencing symptoms of a paralytic illness in 1921 when he was 39 years old. His main symptoms were fevers; symmetric, ascending paralysis; facial paralysis; bowel and bladder dysfunction; numbness and hyperesthesia; and a descending pattern of recovery. He was diagnosed with poliomyelitis and underwent years of therapy, including hydrotherapy at Warm Springs, Georgia. Roosevelt remained paralyzed from the waist down and relied on a wheelchair and leg braces for mobility, which he took efforts to conceal in public. In 1938, he founded the National Foundation for Infantile Paralysis, leading to the development of polio vaccines. Although historical accounts continue to refer to Roosevelt's case as polio, the diagnosis has been questioned in the context of modern medical science, with a competing diagnosis of Guillain–Barré syndrome being proposed.

Bathing is the immersion of the body, wholly or partially, usually in water, but often in another medium such as hot air. It is most commonly practised as part of personal cleansing, and less frequently for relaxation or as a leisure activity. Cleansing the body may be solely a component of personal hygiene, but is also a spiritual part of some religious rituals. Bathing is also sometimes used medically or therapeutically, as in hydrotherapy, ice baths, or the mud bath.

People bathe in water at temperatures ranging from very cold to very hot, or in appropriately heated air, according to custom or purpose.

A bathtub, also abbreviated as bath or tub, is a container for holding water in which a person or another animal may bathe. Modern bathtubs can be made of thermoformed acrylic, porcelain-enameled steel or cast iron, or fiberglass-reinforced polyester. A bathtub is usually placed in a bathroom, either as a stand-alone fixture or in conjunction with shower plumbing.

Sebastian Kneipp (German pronunciation: [zeˈbasti̯a(ː)n ˈknaɪp]; 17 May 1821 – 17 June 1897) was a German Catholic priest and one of the forefathers of the naturopathic movement. He is most commonly associated with the "Kneipp Cure" form of hydrotherapy (often called "Kneipp therapy" or "Kneippism"), the application of water through various methods, temperatures and pressures, which he claimed to have therapeutic or healing effects, thus building several hospitals in Bad Wörishofen.

Although most commonly associated with one area of nature cure, Kneipp was the proponent of an entire system of healing, which rested on five main tenets:

A hot tub is a large tub full of water used for hydrotherapy, relaxation or pleasure. Some have powerful jets for massage purposes. Hot tubs are sometimes also known as "spas" or by the trade name Jacuzzi. Hot tubs may be located outdoors or indoors.

In contrast to a typical bathtub, a hot tub is designed to be used by more than one person at a time, with many models accommodating four or more people. Unlike baths, soaps and shampoos are not used in wet-jetted hot tubs (although they can be used in air-jetted hot tubs). Home hot tubs are often closer in construction to standard bathtubs, while the construction of a public hot tub often has more in common with a swimming pool, of which it can be considered a type.
