Oy, that guy should take a bath! His schvitz is starting to ferment.
Performed in a Russian-Turkish bathhouse, the purpose of a "schvitz" (meaning "sweat"), is multi-fold. Schvitzing, decontaminates the pours, softens the skin, and temporairly lowers blood presure. Some professional fighters use schvitzing, to help make weight for a fight. As it also results in loss of excess water retention. This takes place, in either a dry sauna, or a wet sauna. To complete the process, you douse yourself in ice cold water immediately upon exit, and repeat.
"Damn it's cold outside! Let's warm up with a schvitz!"
