     Baths and bathing have long been considered of medical importance to man. In Greece there are the

ruins of a water system for baths built over 3,000 years ago. The Romans had warm public baths. In

some baths, as many 3,000 persons could bathe at the same time.

      Treating disease by taking bathing has been popular for centuries. Modern medical bathing first

became popular in Europe and by the late 1700's has also become popular in the United States.

       For many years frequent(经常的) bathing was believed to be bad for one's health. Ordinary bathing

just to keep clean was avoided, and perfume was often used to cover up body smells!

       By the 1700's doctors began to say that soap and water were good for health. They believed that it

was good for people to be clean. Slowly, people began to bathe more frequently. During the Victorian

Age of the late 19th century, taking a bath on Saturday night became common.

       In the United States ordinary bathing was slow to become popular. During the 18th and early 19th

centuries, many Americans were know as "The Great Unwashed!" In one American city , for example, a

person was only allowed to take a bathe every thirty days! That was a law!

       Frequency of bathing today is partly a matter of habit. People know that bathing for cleanliness is

important to health, Doctors know that dirty bodies increase the chance of diseases. As a result, in the

United States, people generally bathe often. Some people bath once a day at least. They consider a daily

bath essential (=necessary) to good health.
