A sauna (also sweathouse, sudatory, steambath) is a small room or house designed as a place to experience dry or wet heat sessions, or an establishment with one or more of these and auxiliary facilities. These facilities derive from the Finnish sauna. The word sauna is also used metaphorically to describe an unusually hot or humid environment.
A sauna session is usually a social affair in which the participants disrobe and sit or recline in temperatures of over 80 °C (176 °F). This induces relaxation and promotes sweating.

The modern sauna
Most North American and Western European college/university physical education complexes and many public sports centers and gyms include sauna facilities. They may also be present at public and private swimming pools. This may be a separate area where swimming wear may be taken off or a smaller facility in the swimming pool area where one should keep the swimming wear on.
Under many circumstances, temperatures approaching and exceeding 100 °C (212 °F) would be completely intolerable. Saunas overcome this problem by controlling the humidity. The hottest Finnish saunas have very low humidity levels, which allows air temperatures that could boil water to be tolerated and even enjoyed for long periods of time. Other types of sauna, such as the hammam, where the humidity approaches 100%, will be set to a much lower temperature of around 40 °C (104 °F) to compensate. The "wet heat" would cause scalding if the temperature were set much higher. Finer control over the temperature experienced can be achieved by choosing a higher level bench for those wishing a hotter experience or a lower level bench for a more moderate temperature. Good manners require that the door to a sauna not be kept open so long that it cools the sauna for those that are already in it. A draft, even if at 100 °C, may still be unwelcome.
Infrared saunas are growing in popularity, using far infrared rays emitted by infrared heaters to create warmth.
The sauna can be so soothing that heat prostration or the even more serious hyperthermia (heat stroke) can result. The cool shower or plunge afterwards always results in a great increase in blood pressure, so careful moderation is advised for those with a history of stroke or hypertension (high blood pressure). In Finland, saunas are thought of as a healing refreshment. There is even a saying: "Jos ei viina, terva tai sauna auta, tauti on kuolemaksi." (If a disease can't be cured by booze, tar, or the sauna, it is for death.)
In the Finnish sauna culture, a beer afterwards is thought to be refreshing and relaxing. Pouring a few centiliters of beer into the water that is poured on the hot stones releases the odor of the grain used to brew the beer, and can bring a wonderful smell of freshly baked bread into the air. Also other scents can be used (for example tar or eucalyptus), but using any scents other than birch leaves is frowned upon by the traditionalists.
Social and mixed gender nudity with adults and children is quite common in the conventional sauna. Sometimes the sauna is considered not only a sex-free, but also almost a gender-free zone. It may also be noted that engaging in sexual activity in an environment where the temperature approaches 100 °C would be impractical at the least. In the dry sauna and on chairs one sometimes sits on a towel for hygiene and comfort; in the steam bath the towel is left outside. Some hotel sauna facilities and espescially cruise ships and/or ferries have an area where refreshments (often alcoholic) are served in conjunction with the sauna/pool area; draping a towel around the waist is generally required in that part of such facilities.
As an additional facility a sauna may have one or more jacuzzis.
Health Benefits of Sauna

During a 10-20 minute sauna session, your heart rate increases by 50-75%. This provides the same metabolic result as physical exercise. The increased cardiac load is the equivalent to a brisk walk. There is a nominal effect on blood pressure because the heat also causes blood vessels in skin to expand to accommodate increased blood flow.
Blood vessels become more flexible and there is increased circulation to the extremities. During a sauna, blood flow to the skin increases to as high as 50-70% of cardiac output (compared to the standard 5-10%). This is due to the blood vessels in the skin's surface expanding to accommodate the increased blood flow, a process known as vasodilation. This increased blood flow brings important nutrients to subcutaneous and surface tissue, promoting cellular activity and growth.citation needed] It is especially beneficial to areas of the skin which normally suffer from poor circulation. Along with nourishing the skin, the high temperatures also cause the skin's 2 million eccrine glands to excrete sweat to cool down the skin and blood capillaries. Research has shown that sweat is much more effective than water at emulsifying fat located in the skin's sebaceous glands, and thus at removing the sebum and bacteria lodged in the fat.citation needed] The vasodilation caused by the high temperatures also allow essential fluids to be transported to the skin's surface. This enhances the development of collagen, giving the skin a continued elasticity and wrinkle-free complexion.
Steambaths and saunas induce sweating to provide a comprehensive cleansing of the skin and sweat glands. Skin is the largest organ in the body. 30% of body wastes are passed through the skin. citation needed] Profuse sweating enhances the detoxifying capacity of the skin by opening pores and flushing impurities from the body. citation needed] Sauna is an effective tool for drug detoxification. Research on former drug users has shown that sauna will contribute to evidence of drug metabolites in their system even though there were no detectable metabolites before the sauna regimen started. Researchers have often found that the towels smokers use to sit on in saunas turn yellow as a result of the skin removing impurities and toxins. Similarly, when benches in saunas are replaced, workers often find accumulated deposists of thick, black tar underneath them.
When taking a sauna, skin temperature rises to 40°C (104°F) and internal body temperature rises to about 38°C (100.4°F). Exposure to the high heat creates an artificial fever state, a process known as hyperthermia. Fever is part of the body’s natural healing process. Fever stimulates the immune system, resulting in increased production of disease fighting white blood cells, antibodies and interferon (an anti viral protein with cancer fighting capability).citation needed]
Steam inhalation is an excellent treatment for many respiratory problems. For example, the moist air in saunas can relieve throat irritation. Steam also loosens secretions and can stimulate discharge of mucous from the lungs and throat, giving relief to sufferers of bronchitis. Finally steam can also aid sinusitis by relieving congestion and inflammation of the upper respiratory mucous membranes.
The heat also kills all kinds of bacteria and insects. This knowledge was used widely during the Winter War and Continuation War when Finnish troops were forced to sauna (although with the unclean conditions in the field made it unnecessary to force them). While the men were in their sauna, their equipment was in another. This cleansed both very effectively while Russians had problems with many diseases.citation needed]
However, it should be noted, people with heart problems may be at risk due to blood pressure unpredictably rising or lowering after using a sauna. People with stable coronary artery disease are generally safe in a sauna, but people with uncontrollable heart problems may be advised to stay away from a Sauna by a doctor in order to avoid possible complications.
The Finnish Savusauna
Historical evidence and records indicate that the Finns built the first wooden saunas over 2000 years ago. The early Finnish sauna was dug into a hill or embankment. As tools and techniques advanced, they were later built above ground using wooden logs. Rocks were heated in a stone fireplace with a wood fire. The smoke from the fire filled the room as the air warmed.
Once the temperature reached desired levels, the smoke was allowed to clear and the bathers entered. The wood smoke aroma still lingered and was part of the cleansing ritual. This type of traditional smoke sauna was called a savusauna, which means smoke sauna in Finnish. The smell of smoke and wood is relaxing to most people, especially those who have never been to sauna before.
The evolution of the sauna
Eventually the sauna evolved to use a metal woodstove, or kiuas [ˈkiu.ɑs], with a chimney. Air temperatures averaged around 160-180 degrees Fahrenheit (70-80 °C) but sometimes exceeded 200 °F (90 °C) in a traditional Finnish sauna. Steam vapor, also called löyly [ˈløyly], was created by splashing water on the heated rocks.
The steam and high heat caused bathers to perspire, thus flushing away impurities and toxins from the body. The Finns also used a vihta [ˈvihtɑ] (Western dialect, aka vasta in Eastern dialect), which is a bundle of birch twigs, to gently slap the skin and create further stimulation of the pores and cells.
The Finns also used the sauna as a place to cleanse the mind, rejuvenate and refresh the spirit, and prepare the dead for burial. The sauna was an important part of daily life, and families bathed together in the home sauna. Those of differing sexes generally do not mix in public saunas in the modern era, though groups of friend sometimes do. Indeed Sauna was originally place of mystical nature where gender/sex differences did not exist. Because the sauna was often the cleanest structure and had water readily available, Finnish women also gave birth in the sauna.
When the Finns migrated to other areas of the globe, they brought their sauna designs and traditions with them, introducing other cultures the enjoyment and health benefits of sauna. This led to further evolution of the sauna, including the electric sauna stove, which was invented and implemented in the 1950s and far infrared saunas, which have become popular in the last several decades.

Infrared Saunas, Wet, Dry, Smoke and Steam Saunas
Infrared saunas use a special heater that generates infrared radiation rays similar to that produced by the sun. Unlike the sun’s ultraviolet radiation, infrared is said to be beneficial to overall health. In an infrared sauna, the electric heaters warm the air and also penetrate the skin to encourage perspiration, producing many of the same health benefits of traditional steam saunas.
Today there are a wide variety of sauna options. Heat sources include wood, electricity, gas and other more unconventional methods such as solar power. There are wet saunas, dry saunas, smoke saunas, steam saunas, and those that work with infrared waves as described above.
You can have a sauna in your home or apartment, in your backyard, on your rooftop, or even in a vehicle or on a pontoon boat. The possibilities are endless and creating innovative and sometimes quirky designs has become part of the appeal of sauna bathing. But for most people, it is still the health benefits that are the main attraction.
Saunas and sex
In some countries there are adult-only saunas that have different rules and customs, the term "sauna" being used for a bath-house or "health club", sometimes with facilities like a standard sauna, but where people go to find sexual partners and have sex on the premises (however not in the sauna itself). Some such saunas rent out small rooms for this purpose: others are disguised brothels. This euphemistic usage generally applies to establishments that advertise themselves as being a sauna rather than those that have a sauna on the premises. This generally happens more frequently in inner-city areas of the UK (see also Massage parlour) and US than in continental Europe where a sauna is generally seen as a family or social event. In Finland, where the amount of Saunas/capita is by far the highest in the world, and families regularily bathe together nude, sex in Sauna is in fact a social taboo even though the use of saunas and bathhouses as brothels dates back to the medieval 'stews', the original European brothels.
Similar sweat bathing facilities
The Finnish-style sauna (generally 70-80 °C (158-176 °F), but can vary from 60 to 120 °C (140-248 °F)) and the wet steam bath are the most widely known forms of sweat bathing. Many cultures have close equivalents, such as the North American First Nations sweat lodge, the Turkish hammam, Roman thermae, Nahuatl (Aztec) temescalli, Maya temazcal, Russian banya, the Jewish Shvitz, African Sifutu, and Japanese Mushi-Buro. Public bathhouses that often contained a steam room were common in the 1700s, 1800s and early 1900s and were inexpensive places to go to wash when private facilities were not generally available.
Modern sauna culture around the world
As the home of the sauna, Finnish sauna culture is well established. Although cultures in all corners of the world have imported and adapted the sauna, many of the traditional customs have not survived the journey. Today, public perception of saunas, sauna "etiquette" and sauna customs vary hugely from country to country. In many countries sauna going is a recent fashion and attitudes towards saunas are changing, while in others traditions have survived over generations.
In Finland, Estonia and Russia sauna-going plays a central social role. These countries boast the hottest saunas and the tradition of beating fellow sauna-goers with leafy, wet birch bunches ('vasta' or 'vihta' in Finnish, 'viht' in Estonian). In Russia public saunas are strictly single sex while in Finland and Estonia both types occur.
Benelux and Scandinavian countries, where public saunas have been around for a long time too, generally have a moderate, "live and let live" attitude towards sauna-going with few traditions to speak of. Levels of nudity vary, single sex saunas are as common as mixed sex saunas and people tend to socialise.
In Germany and Austria on the other hand, nudity is strictly enforced in public saunas, as is the covering of benches with towels. Separate single-sex saunas for both genders are rare, most places offer women-only and mixed-gender saunas, or organise women-only days for the sauna once a week. Loud conversation is not usual as the sauna is seen as a place of healing rather than socialising. Contrary to Scandinavian countries, pouring water on hot stones to increase humidity (Aufguss) is not normally done by the sauna visitors themselves, but rather by a person in charge (the Saunameister), either an employee of the sauna complex or a volunteer. Aufguss sessions can take up to 10 minutes, and take place according to a schedule. During an Aufguss session the Saunameister uses a large towel to percolate the hot air through the sauna, intensifying sweating and the perception of heat. Once the Aufguss session has started it is not considered good manners to enter the sauna, as opening the door would cause loss of heat (Sauna guests are expected to enter the sauna just in time before the Aufguss. Leaving the session is always, but grudgingly tolerated). Aufguss sessions are usually announced by a schedule on the sauna door. An Aufguss session in progress might be indicated by a light or sign hung above the sauna entrance. Cold showers or baths shortly after a sauna, as well as exposure to fresh air in a special balcony, garden or open-air room (Frischluftraum) are considered a must.
In (at least the German-speaking part of) Switzerland it is generally the same as in Germany and Austria, although you tend to see more families (parents with their children) and young people. Also in respect to socialising in the sauna the Swiss tend more to be like the Swedes or Finns. Also in German speaking countries, there are many facilities for washing after using the sauna, with 'dunking pools' (pools of very cold water in which a person dips themselves after using the sauna), showers. In some saunas and steam rooms, scented salts are given out which can be rubbed into the skin for extra aroma and cleaning effects.
In much of southern Europe, France and the UK single gender saunas are more common than mixed gender saunas. Nudity is tolerated in the segregated saunas but strictly forbidden in the mixed saunas, a cause of confusion when residents of these nations cross the border to Germany and Austria or vice versa. Sauna sessions tend to be shorter and cold showers are shunned by most. In the UK, where public saunas are becoming increasingly fashionable, the practice of alternating between the sauna and the jacuzzi in short seatings (considered a faux pas in Northern Europe) has emerged.
Saunas in Slovenia and Croatia have setups similar to those in Germany and Austria, and are perhaps a bit more relaxed about enforcing rules.
Hungarians see the sauna a part of a wider spa culture. Here too attitudes are less liberal, mixed-gender people are together and they wear swimsuits. Single-sex saunas are rare, as well as those which tolerate nudity.
In Latin America, particularly in the highlands of southern Mexico and Guatemala, a version of the sauna indigenous to the Americas, called temazcal, is quite popular. The temazacal is usually made of clay or stone, and has a low ceiling. The temazcal structure is usually shared by an extended family unit. Unlike European sauna culture, temazcal is an individual rathern than social activity. One washes in the temazcal, with soap, or in a more traditional setting, with herbs and medicinal bushes. One uses the temazacal only in the evening, so that upon exiting one can feel the chill of the cold evening air (temperature can fall below freezing at high altitudes). One usually bathes in the temazacal 2-3 times a week.
In Africa, on the whole, saunas are kept at a much lower temperature than in Europe.
In Korea, saunas are essentially public bathhouses. Various names are used to describe them, such as the smaller mogyoktang, outdoor oncheon, and the elaborate jjimjilbang. The word 'sauna' is used a lot for it's 'english appeal', however it does not strictly refer to the original Scandinavian steam rooms that have become popular throughout the world. The konglish word sauna (사우나) usually refers to bathhouses with jacuzzis, hot tubs, showers, steam rooms, and related facilities.
In Japan, many saunas exist at sports centers and public bathhouses (sentos). The saunas are almost always gender separated, often required by law, and nudity is a required part of proper sauna etiquette. While right after World War II, public bathhouses were commonplace in Japan, the number of customers have dwindled as more people were able to afford houses and apartments equipped with their own private baths as the nation became wealthier. As a result many sentos have added more features such as saunas in order to survive.
Unfortunately for sauna enthusiasts in the United States, sauna culture is not widespread outside of the Upper Peninsula of Michigan, which is home to a large Finnish-American population. Elsewhere, while sauna facilities are often provided at health clubs and at hotels, they frequently remain unheated because of disuse. To avoid liability, many saunas operate at only moderate temperatures and do not allow pouring water on the rocks. Sauna users enter and exit the sauna as they please, alternately nude, fully dressed in workout clothes, or dripping wet in swimsuits. In some health clubs, the sauna gets more use from patrons drying wet clothing than for taking a sauna. Proper saunas in the United States are either private or are businesses serving a particular ethnic group with a more developed sauna culture.
Sauna traditions and old beliefs
In Finland, the sauna is an ancient thing. It used to be a holy place, a place where women gave birth, and where the bodies of the dead were washed. There were also many beliefs and charms that were connected to sauna. It was, among other things, a place for worshipping the dead – it was thought of as such a wonderful place that even the dead would surely like to return to it. Curing diseases and casting love spells could also happen in the sauna. As in many other cultures, fire was seen as a gift from heaven in Finland, and the hearth and the sauna oven were its altars.
One word in Finnish, strictly connected to sauna, is löyly. It is a bit difficult to translate, but basically it means the heat of the sauna room, especially the heat you get when you throw water on the hot stones of the sauna oven. Originally this word meant spirit or life. In many languages which are related to Finnish, there is a word corresponding to löyly. An example would be lil in Ostyak, which means soul, or leil in Estonian. All this also hints to the sauna's old, spiritual essence.
There still exists an old saying, "saunassa ollaan kuin kirkossa," – you should be in the sauna as in a church.
Saunatonttu is a little gnome that was believed to live in the sauna. He was always treated with respect, otherwise he might cause much trouble for people. It was customary to warm up the sauna just for the gnome every now and then, or to leave some food outside for him. It is said that he warned the people if a fire was threatening the sauna, or punished people who behaved improperly in it – for example slept, or played games or behaved otherwise "immorally" there.
