A room designed for sweating, typically used for relaxation and health benefits, often found in spas or bathhouses.
After a long workout, I enjoyed a session in the sudatorium to help my muscles relax.
Sudatorium is derived from "sudare" (meaning to sweat) and the suffix "-orium" (indicating a place). The word refers to a place designed for sweating, such as a steam bath or sauna.
Imagine a place where you go to 'sweat' ('sudare') — that's what a sudatorium is, a place for sweating.
