As early as in ancient Greece, Hippocrates, the father of Western medicine, used hot springs for treatment. In addition, ancient China and Japan also recorded hot spring therapy.
Until the 18th-19th century, Sebastian Kneipp, the father of the German spa, published the spa as a formal medical use.
Spas are often used to treat diseases such as muscles and bones, and the popular "SPA" is also a type of spa.
The effects of spa on the human body are mainly temperature stimulation, mechanical stimulation and chemical stimulation.
