Sauna (pronounced /ˈsɔːnə/, or as Finnish [ˈsɑunɑ]) 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 can be 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 oldest known saunas were pits dug in a slope in the ground and primarily used as dwellings in winter. The sauna featured a fireplace where stones were heated to a high temperature. Water was thrown over the hot stones to produce steam and to give a sensation of increased heat. This would raise the apparent temperature so high that people could take off their clothes. Many 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 relatively low humidity levels in which steam is generated by pouring water on the hot stones. This allows air temperatures that could boil water to be tolerated and even enjoyed for longer periods of time. Steam baths, 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. A good sauna has a relatively small temperature gradient between the various seating levels. 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. Leaving the door even slightly ajar or keeping it open for more than a few seconds will significantly cool down the relatively small amount of hot air inside the sauna. Infrared saunas are growing in popularity, using far infrared rays emitted by infrared heaters to create warmth.
According to some old treatises, a sauna gives ten benefits, which include clarity, coolness, energy, health, strength, beauty, youth, cleanness, silk skin and women's attention. Being in a sauna positively affects the functioning conditions of major human organs and intensifies metabolism. In the end, sauna is just very pleasant. There are many saunas in Kiev.
