A sauna (pronounced /ˈsɔːnə/, or as Finnish ) 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.
History
Etymology
The word sauna is an ancient Finnish word referring to the traditional Finnish bath as well as to the bathhouse itself. The proto-Finnic reconstruction is *savńa. There are etymological equivalents in the Baltic-Finnic languages such as the Ingrian and Votic word sauna, Estonian saun and Livonian sōna. The word suovdnji in Sámi means a pit dug out of the snow, such as a hole for a willow grouse. In Baltic-Finnish, sauna does not necessarily mean a building or space built for bathing. It can also mean a small cabin or cottage like a cabin for a fisherman.
First saunas
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.
