Mineral or hot springs are also known as geothermal waters and are often used for therapeutic treatments, as well as for revitalizing and relaxing the mind and body. The three components in mineral baths that are used therapeutically are the temperature of the water, dissolved minerals and gases in the water, and mud.
Mineral baths have been used for centuries to relieve health problems and for general relaxation. Soaking in mineral water has several benefits. Soaking in a hot spring can be wonderful therapy, for a number of reasons. The heat and subsequent sweating have a deeply cleansing effect on our skin and entire body system.
Among the minerals provided by mineral water are magnesium, chloride and bicarbonates, sulfate and silica and iron aids. Mineral waters are usually classified as alkaline, saline, ferrous, sulfurous, acidulous, or soda, and may be either cold or hot. Mineral baths differ in chemical composition and in the types of gases that are present. Mineral baths used for therapeutic purposes must contain at least 1 gram per liter of dissolved solids. The most common dissolved minerals and gases include calcium, sodium, magnesium, potassium, chloride, silicon dioxide, iron, bicarbonate, carbon dioxide, and hydrogen sulfide.
Spas, by definition, are located where natural sources of mineralized water are used for drinking or bathing to enhance good health.
The term “spa” was named after Spa, a town in eastern Belgium, which is a popular resort known for its baths and mineral springs. The waters have been frequented since ancient times. Such spas remain popular worldwide.
