A Finnish word for a warm room (temperatures around 80-140°C) used for cleansing and relaxation even more importantly. A sauna is equipped with wooden seating (in Finnish lauteet) and a casing holding an amount of stones heated by electricity or by burning wood (kiuas). Water is thrown on these hot rocks to create steam which makes you sweat thus making the dirt on your skin loosen. Traditionally going to sauna is accompanied by couple of beers and swimming in lake (summertime) or rolling in snow (wintertime). For Finns sauna is almost a holy place and great care has to be taken to behave in a corresponding manner (no farting, no yelling :).
"Let's go to sauna and after that have some beers."
