Finnish sauna: What it is all about<\/h2>\n\n\n\n

The word \u201eSauna\u201c comes from Finnish. In Finland, sauna bathing is part of everyday life: In 2020, UNESCO added the Finnish sauna culture to the Representative List of the Intangible Cultural Heritage of Humanity. According to their data, there are 3.3 million saunas in Finland with 5.5 million inhabitants. The sauna is not only used for body care; people cleanse their bodies and minds there and find peace and quiet.<\/p>\n\n\n\n

The centerpiece of the experience is the \u201eL\u00f6yly\u201c: the steam that is created when water is poured onto hot rocks. It increases the perceived heat and sweating. The way a steam bath usually works is explained in the article. Sauna steaming: types, procedure and etiquette<\/a>.<\/p>\n\n\n\n

Construction: Fireplace, stones and benches<\/h3>\n\n\n\n

The cabin is lined with wood and is heated by a stove that can be operated electrically, with wood or on gas. According to Wikipedia, the benches are located in two to three levels at a height of 0.5 to 1.5 meters; the heat gets noticeably stronger the higher up you go. Therefore, those who are not accustomed to the heat should initially sit lower down (ZDFheute).<\/p>\n\n\n\n

The smoking sauna: the original form<\/h3>\n\n\n\n

The smoke sauna is considered the original form of the Finnish sauna. According to Wikipedia, a stone pile is heated with wood for hours to create the smoke. thisisFINLAND, the portal of the Finnish Ministry of Foreign Affairs, describes the heat as soft; it smells of wood smoke.<\/p>\n\n\n\n

Finnish sauna: Temperature and humidity<\/h2>\n\n\n\n

According to thisisFINLAND, the Finnish Sauna Society recommends 80 to 100 \u00b0C; some people feel comfortable at 70 \u00b0C already. A competition to see who can reach the highest temperature is considered \u201eboth silly and unhealthy\u201c (in the original, \u201eboth silly and unhealthy\u201c). Visit Finland lists 70 to 90 \u00b0C as the typical range. Cologne Badeschampagner lists 90 \u00b0C and 5 to 10 percent humidity for their Finnish steam saunas, which increases to up to 30 percent during the steam bath.<\/p>\n\n\n\n

The values come from the Wikipedia overview on saunas, which cites the German Sauna Association as a source among others. Operators cite varying figures. For more information on humid heat, see the article Steam bath or sauna<\/a>.<\/p>\n\n\n\n

Process of a sauna session in the Finnish sauna<\/h2>\n\n\n\n

The Golden Rules of the German Sauna Association describe a typical process. A full sauna session takes about two hours; one should not rush into it and not start on an empty stomach.<\/p>\n\n\n\n

    \n
  1. Preparation:<\/strong> First, take a shower and dry off thoroughly, because dry skin sweats faster. A warm foot bath also promotes sweating.<\/li>\n\n
  2. Sweating:<\/strong> The sheet is placed under the entire body. Sweating occurs for eight to fifteen minutes, based on your own feeling. In the last two minutes, sit down so that the circulation system gets used to the upright position.<\/li>\n\n
  3. Cooling down:<\/strong> Do not shower or go into the diving pool immediately, but first cool off in the fresh air. Then follow with a Kneipp hose or a jet shower; the sweat must be washed off before entering the diving pool.<\/li>\n\n
  4. Rest:<\/strong> A warm foot bath helps to balance the temperature; after that, a short rest is recommended.<\/li>\n\n
  5. Repeat:<\/strong> Further sessions follow the first. According to the Sauna Association, three sauna sessions are sufficient; more do not increase the effect.<\/li>\n<\/ol>\n\n\n\n

    How do the Finns do it?<\/h3>\n\n\n\n

    In Finland, there are no fixed times. According to thisisFINLAND, there are usually at least two sauna sessions; you stay as long as it is comfortable and then cool down in a shower, a lake or in the snow. Visit Finland lists a duration of 5 to 10 minutes to up to hours of sauna with cooling breaks. Nudity is common, but a swimsuit or towel is also fine according to Visit Finland.<\/p>\n\n\n\n

    Finnish sauna or organic sauna?<\/h2>\n\n\n\n

    The Finnish sauna is hot and dry, the organic sauna is significantly cooler and more humid. Those who cannot tolerate heat well or prefer to stay in milder heat for longer will find an alternative in the organic sauna; those who appreciate the steam and intense heat are right in the Finnish sauna. Which option you get depends on your health as well.<\/p>\n\n\n\n

    The issue of clothing should not be confused with the sauna: the organic sauna and the Finnish sauna describe the climate; the textile sauna describes the clothing. In Germany, bathing attire in saunas is usually not allowed for hygienic reasons, except in special textile saunas (Apotheken Umschau). According to sauna master Romelia Fiering, nudity is not mandatory; as an alternative, she suggests a sauna kilt or a hamam cloth. The house rules always apply.

    Health and contraindications<\/h2>\n\n\n\n

    The Finnish sauna strains the cardiovascular system: According to Barmer, the heart rate rises to about 120 to 150 beats per minute. For healthy adults, sauna use in moderation is considered safe. Among other things, you should avoid it or seek medical advice if you:<\/p>\n\n\n\n
