A spa is a location where mineral-rich spring water (and sometimes seawater) is used to give medicinal baths. Spa towns or spa resorts (including hot springs resorts) typically offer various health treatments, which are also known as balneotherapy. The belief in the curative powers of mineral waters goes back to prehistoric times. Such practices have been popular worldwide, but are especially widespread in Europe and Japan. Day spas and medspas are also quite popular, and offer various personal care treatments.
Mineral spa
The term is derived from the name of the town of Spa, Belgium, whose name is known from Roman times, when the location was called Aquae Spadanae, sometimes incorrectly connected to the Latin word spargere meaning to scatter, sprinkle or moisten.
Since medieval times, illnesses caused by iron deficiency were treated by drinking chalybeate (iron-bearing) spring water (in 1326, the iron-master Collin le Loup claimed a cure, when the spring was called Espa, a Walloon word for "fountain").
In 16th-century England, the old Roman ideas of medicinal bathing were revived at towns like Bath (not the source of the word bath), and in 1596 William Slingsby who had been to the Belgian town (which he called Spaw) discovered a chalybeate spring in Yorkshire. He built an enclosed well at what became known as Harrogate, the first resort in England for drinking medicinal waters, then in 1596 Timothy Bright after discovering a second well called the resort The English Spaw, beginning the use of the word Spa as a generic description.
It is commonly claimed, in a commercial context, that the word is an acronym of various Latin phrases, such as salus per aquam or sanitas per aquam, meaning "health through water". This is very unlikely: the derivation does not appear before the early 21st century and is probably a backronym as there is no evidence of acronyms passing into the language before the 20th century; nor does it match the known Roman name for the location.

Public baths originated when most people in population centers did not have access to private bathing facilities. Though termed "public", they have often been restricted according to gender, religious affiliation, personal membership, and other criteria. In addition to their hygienic function, public baths have also been social meeting places. They have included saunas, massages, and other relaxation therapies, as are found in contemporary day spas.
A swimming pool, swimming bath, wading pool, paddling pool, or simply pool, is a structure designed to hold water to enable swimming or other leisure activities. Pools can be built into the ground (in-ground pools) or built above ground (as a freestanding construction or as part of a building or other larger structure), and may be found as a feature aboard ocean-liners and cruise ships.
Bathing is the act of washing the body, usually with water, or the immersion of the body in water. It may be practiced for personal hygiene, religious ritual or therapeutic purposes. By analogy, especially as a recreational activity, the term is also applied to sun bathing and sea bathing. People bathe at a range of temperatures, according to custom or purpose, from very cold to very hot. In the western world, bathing is usually done at comfortable temperatures in a bathtub or shower.

We analyze an open many-body system that is strongly coupled at its boundaries to interacting quantum baths. We show that the two-body interactions inside the baths induce emergent phenomena in the spin transport. The system and baths are modeled as indepe ...
