The traditional definition of a spa is:
A PLACE OF NATURAL OCCURRING THERMAL OR MINERAL WATERS.
For centuries people have travelled to certain towns or places that were renowned for the curative effects of the local water. They would either drink the water or immerse themselves in it believing that it had special healing powers.
The Latin words - Sanus Per Aquam mean health through water
There are also those who associate the term "Spa" with the name of a town in Belgium that drew people from many areas to its healing waters during the 16th century. Water therapy has in fact been in existence for thousands of years and there is documented evidence that the Indians, Egyptians, Assyrians and Mohammedans used mineral waters for curative purposes. Many people including the Japanese, Chinese, Greeks and in particular the Romans used warm baths for therapeutic purpose, relaxation, reducing fatigue, promoting wound healing and increasing a sense of well being.
