Changes

Romans often built baths as one of the first things in a town they conquered or built. People would also exercise, often to help built a sweat so that it is easier to remove skin and dirt, while they would also be massaged. Oil treatments, often of varying quality, would be made available to people. There were also two main types of baths, one hot (<i>calidarium</i>) and the other cold (<i>frigidarium</i>). The hot baths were also used to make saunas as water was thrown into the heated rooms, where underground heated bricks would heat the floors and walls. Effectively, Roman baths began to become similar to our concept of spas, where people go to receive massages, skin treatments, relax, and bathe. Roman baths have most likely shaped our concepts of spa treatments and other cultures' baths that followed in the Medieval period. Bath houses continue to spread in many regions, including in Central Asia and China, by at least 200 BC, where these regions began having public bath houses. The spread of public baths could have happened through travelers and merchants that began to connect Eurasia during the Old World. Probably by around 1 AD, bath houses could be found anywhere between Britain and Japan.<ref>For more on the development of bath houses in the Old World and their structure, see: Yegül, F. K.
