For generations, people worldwide have found comfort in the soothing embrace of the sauna, with evidence of earthen sauna pits dating back to 2000 BC that used fire-heated stones to create a warm place to sustain the harsh climate of Northern Europe. Thought to primarily originate in Finland, the practice of hyperthermia or intentional heat exposure is seen around the globe with Indigenous North American sweat lodge, Japanese onsen, Roman thermae, Russian Banya, Swedish Bastu, and Turkish Hammam.  More than just a warm refuge, these spaces are havens for relaxation, cleansing, and community connection.
