Balneotherapy

Balneotherapy (from Latin: balneum, "bath") is the treatment of disease by bathing, usually practiced at spas. While it is considered distinct from hydrotherapy, there are some overlaps in practice and in underlying principles. Balneotherapy may involve hot or cold water, massage through moving water, relaxation or stimulation. Many mineral waters at spas are rich in particular minerals (silica, sulfur, selenium, radium) which can be absorbed through the skin. Medicinal clays are also widely used, which practice is known as 'fangotherapy'.

While the treatments have been mainly recommended for physical disorders they have been prescribed as a treatment for mental disorders

Definition and characteristics
The term "balneotherapy" is generally applied to everything relating to spa treatment, including the drinking of waters and the use of hot baths and natural vapor baths, as well as of the various kinds of mud and sand used for hot applications. Balneotherapy refers to the medical use of these spas, as opposed to recreational use. Common minerals found in spa waters are sodium, magnesium, calcium and iron, as well as arsenic, lithium, potassium, manganese, bromine, and iodine. All these may be contained in the peat that is commonly used in preparation of spa waters. Resorts may also add minerals or essential oils to naturally-occurring hot springs. Though balneotherapy commonly refers to mineral baths, the term may also apply to water treatments using regular hot or cold tap water.

Mud-baths are also included in balneotherapy, and the dirt and water used to mix mud baths may also contain minerals which are thought to have beneficial properties.

Treatment of diseases
Balneotherapy may be recommended for wide range of illnesses, including arthritis, skin conditions and fibromyalgia. As with any medical treatment, balneotherapy should be discussed with a physician before beginning treatment, since a number of conditions, like heart disease and pregnancy, can result in a serious adverse reaction.

Scientific studies into the effectiveness of balneotherapy tend to be neutral or positive, finding that balneotherapy provides no effect or a placebo effect, or that there is a positive effect. However, many of these studies suffer from methodological flaws, and so may not be entirely reliable. A 2009 review of all published clinical evidence concluded that, while available data suggest that balneotherapy may be truly associated with improvement in several rheumatological diseases, existing research is not sufficiently strong to draw firm conclusions.
