What was the primary purpose of the tepidarium?

The tepidarium, a key feature of Roman baths, served primarily as a transitional space for bathers to acclimate their bodies to different temperatures. Typically found between the caldarium (hot bath) and the frigidarium (cold bath), the tepidarium was designed to raise the body's temperature gradually after leaving the hot environment, thereby easing the transition to the cooler surroundings. This careful regulation of temperature was essential for promoting overall well-being and hygiene, as well as enhancing the experience of communal bathing in the ancient Roman culture. Consequently, the tepidarium was not merely a place for prolonged soaking, but rather an integral part of the bathing process, making it crucial for a proper thermal regimen.
