A sauna (, Finnish: [ˈsɑu̯nɑ]) is a room or building designed as a place to experience dry or wet heat sessions or an establishment with one or more of these facilities. The steam and high heat make the bathers perspire. A thermometer in a sauna is used to measure temperature; a hygrometer can be used to measure levels of humidity or steam. Infrared therapy is often referred to as a type of sauna, but according to the Finnish sauna organizations, infrared is not a sauna.

[edit] Main article: Finnish sauna A sauna session can be a social affair in which the participants disrobe and sit or recline in temperatures typically between 70 and 100 °C (158 and 212 °F). This induces relaxation and promotes sweating. People use a bundle of birch twigs with fresh leaves (Finnish: vihta or vasta; Estonian: viht), to slap the skin and create further stimulation of the pores and cells. [...] Smoke sauna (Finnish savusauna, Estonian suitsusaun, Võro savvusann) is one of the earliest forms of the sauna. It is simply a room containing a pile of rocks but without a chimney. A fire is lit directly under the rocks and after a while, the fire is extinguished. The heat is retained in the rocks, and the earlier fire becomes the main source for heating the sauna. Following this process, the ashes and embers are removed from the hearth, the benches and floor are cleaned, and the room is allowed to air out and freshen for some time. The smoke deposits a layer of soot on every surface, so if the benches and back-rests can be removed while the fire is alight the amount of cleaning necessary is reduced. Depending on the size of the stove and the airing time, the temperature may be low, [...] As a result of the Industrial Revolution, the sauna evolved to use a wood-burning metal stove with rocks on top, kiuas, with a chimney. Air temperatures averaged around 75–100 °C (167–212 °F) but sometimes exceeded 110 °C (230 °F) in a traditional Finnish sauna. As the Finns migrated to other areas of the globe, they brought their sauna designs and traditions with them. This led to a further evolution of the sauna, including the electric sauna stove, which was introduced in 1938 by Metos Ltd in Vaasa. Although sauna culture is more or less related to Finnish and Estonian culture, the evolution of the sauna took place around the same time in Finland and Baltic countries; they all have valued the sauna, its customs and traditions until the present day.
- Sauna and sleep - Sauna
Bathing in the sauna makes falling asleep easier and usually improves the quality of sleep. As a result, it also allows us to think more clearly and make important decisions. The information on the page was compiled by Raili Vihavainen. [...] We know that the sauna relaxes the body and mind, inducing pleasant and calm feelings. In addition to that, studies have shown that the sauna has a positive impact on our sleep as well. Sauna bathing increases the amount of deep sleep we get, and sufficiently deep sleep, in turn, affects our memory functions, learning and problem solving skills in a positive way. Through good sleep, bathing in the sauna promotes our ability to think and, subsequently, our ability to make important decisions. ### The sauna’s effects on sleep [...] ### Falling asleep becomes easier Most test subjects found it easier to fall asleep after a bathing session in the sauna, with only around three per cent experiencing increased difficulties. Furthermore, one third of the respondents felt that the sauna had no effect on how quickly they were able to fall asleep. Over 40% found the sauna to have a positive impact on their sleep quality, although the majority (approx. 60%) said that they had not experienced a significant impact. Only two per cent of the respondents stated that they tend to sleep worse after the sauna. The reason for this is unclear, but it may be connected to migraines.
- 5 surprising health benefits of sauna use
## Types of saunas A sauna is a small room filled with dry heat. Traditional Finnish saunas are common in many health clinics, day spas and recreational facilities. These are small, wood-planked rooms that are heated to a temperature somewhere between 70° to 100° Celsius (158° to 212° Fahrenheit) with a relative humidity of 10 to 20 percent. Heating is usually achieved with electricity or burning wood. Many of these saunas feature rocks that users can douse with water to increase the relative humidity in the air. [...] ## Is the sauna safe for me? Most researchers and doctors agree that sauna bathing is safe and well-tolerated in most people when utilized properly, but it's not right for everyone. You should always check with your personal health care provider before using a sauna for the first time, especially if you have any medical conditions, are taking any prescription medications, are pregnant or are under medical supervision. Research suggests that sauna use is not safe for people with certain health conditions, including: Finally, don't consume alcohol if using a sauna, as this could increase the risk of potentially serious sauna-related complications including dehydration, decreased blood pressure, abnormal heart rhythms and even death in extreme cases. [...] As for how sauna use confers these health benefits, researchers have proposed a variety of possible mechanisms. For example, it's been suggested that sitting in a sauna may help by reducing oxidative stress and inflammation, improving blood vessel function and beneficially activating different parts of the nervous system. These aren't the only suggested benefits of regular sauna use, by the way. For example, some reports indicate that sauna bathing may improve sleep and ease certain skin conditions like psoriasis. More research will help us understand all the ways saunas are health-promoting and who could benefit from regular use. ## Is the sauna safe for me?
- Sauna and Unesco - Sauna
Happy news were received in early June 2018: the Ministry of Education and Culture had selected sauna bathing as Finland’s first nomination for Unesco’s list! Autumn 2018 was spent preparing the Unesco application and its appendices. The finished application was submitted to the Finnish Heritage Agency at the end of 2019. Subsequently, on 31 March 2019, the Ministry of Education and Culture sent the application to Unesco. Unesco (United Nations Educational, Scientific and Cultural Organization) decided to include the Finnish sauna bathing tradition to its list of intangible cultural heritage ( on 17 December 2020. Sauna bathing is the first Finnish tradition added to this list. Sauna bathing in the Wiki-Inventory for Living Heritage Sauna coalition’s open Facebook group [...] Project stages In November 2017, Sauna bathing was added to the National Inventory of Living Heritage in Finland (link in Finnish), alongside 51 other items. In addition to sauna bathing, the Inventory includes traditions such as taking candles to the cemetery on Christmas Eve, the freedom to roam, the game of pesäpallo and the thriftiness of people from Laihia. Items included in the Inventory of Living Heritage can be nominated for Unesco’s lists of intangible cultural heritage. In January 2018, a panel was held at the Finnish Sauna Society’s premises in Vaskiniemi, Helsinki, for Finnish sauna enthusiasts. As a result, sauna-related operators from around Finland decided to initiate a project aiming to have sauna bathing added to Unesco’s list. [...] The aim of the Convention is to promote the protection of intangible cultural heritage, guarantee respect towards the intangible cultural heritage of communities, groups and individuals, and increase awareness of the importance of intangible cultural heritage. The Convention emphasises the elements of passing on traditions, cultural diversity and people’s ownership of their cultural heritage. The focus is on the communities, groups and individuals practising traditions. They themselves can decide what is important and worth saving. Project stages

PubMed, Web of Science, Scopus, and Proquest were initially searched with keyword “sauna” and date restrictions of January 2000–April 2017. Search dates were chosen to focus on updated findings reflecting advancing technology in both diagnostics and physiological monitoring to build upon the foundational literature of prior nonsystematic clinical reviews of sauna activity published in the early 2000s. After further restrictions of English language and humans, records were then expanded using Google Scholar, with searches for other research by key authors, searches of citations and reference lists of original and review articles, and other “related articles”. Additional searches with expanded keywords relating to sauna including “interventional study”, “whole body hyperthermia”, and “whole
