Treating diseases by bathing has been popular for centuries. Modern medical bathing, or hydrotherapy, first became popular in Europe and by the late 1700’s also became popular in the United States.

For many years frequent bathing was believed to be bad for one’s health. Ordinary bathing just to be clean was avoided, and perfume(香水) was used to cover up body and smell.

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.

In the United States ordinary bathing was slow to become popular. During the 18th and early 19th centuries, many Americans were known as“the great unwashed”.In one American city, for example, a person could only take a bath every 30 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 disease. Therefore in the United States people generally bathe often.
