Sauna culture in Finland is real, and it’s something you must experience when you’re there. It is estimated that there are two million saunas in Finland, for a population of 5.5 million. Big companies and state institutions have their own saunas, as well as government officials, and private residences. They can be found in city apartments, private clubs, and at country cottages. Traditional saunas are heated by wood, burned either in a stove with a chimney or by a stove with no chimney. All saunas have a basket of rocks heated by the stove that you throw water on to increase the humidity in the room. Aside from keeping warm in the winter, the Finns use saunas to relieve stress, improve cardiovascular health, flush toxins, and help fight illnesses.
