Need to relax after a few stressful months? Perhaps you need to go to a spa.

First of all, what exactly is a spa? Traditionally, spas were places with a natural spring producing warm waters that could be used in hydrotherapy (水疗法) treatments. They were places where you “took the waters” --- meaning you drank some of the water or bathed in it.

But nowadays, a “spa” can mean a variety of things. In general, the term is often used to refer to commercial establishment that provides many services for health, fitness, weight loss, beauty and relaxation. This may include exercise classes, mud baths, body treatment, facials (美容), etc.

In Japan, traditional hot springs have attracted visitors for centuries. And thermal baths (温泉浴) have been found in the ruins of the Cretan Palace of Knossos (2000-1400 B.C.). It was the Romans who made spas popular in Europe. They established a number of towns around thermal waters. These include the English town of Aquae Sulis (which is called Bath today), and the Belgian town of Aquae Spadanae (which is known as Spa these days).

In the 18^th century, spas became the fashionable places to go on holiday. Bath and Harrogate in the UK were popular with British rich people. And in Europe Carsbad (now called Larlovy Vary), Marienbad and Franzensbsf were Europe’s most important holiday centers.

A typical day in Carsbad in the 19^th century went as follows. Visitors got up at 6:00 a.m. to take the waters and listen to music by a band. Next, came a light breakfast, a bath in the waters, and then lunch. In the afternoon, visitors went sightseeing, walked or attended concerts. After dinner, there were theatrical performances. Guests returned to their hotels at about 9 p.m. to rest until six the following morning. Visitors would stay for as long as a month. Some of the more famous patients at these spas included the composers Beethoven and Chopin, and the Russian writer Turgnev.

Marienbad was the best spa town. It was popular with the inventor Thomas Edison, the writer Johann Goethe, and many famous people and European emperors.

Today, although taking the waters isn’t as common as it used to be, spa treatments are more popular than ever.
