Turkish hamam or Turkish bath is a type of steam bath or a place of public bathing associated with the Islamic world. It is a prominent feature in the culture of the Muslim world and was inherited from the model of the Roman thermae. Muslim bathhouses or hammams are historically found across the Middle East, North Africa, al-Andalus (Islamic Spain and Portugal), Central Asia, the Indian subcontinent, and in central and Eastern Europe under Ottoman rule. A variation on the Muslim bathhouse, the Victorian Turkish bath, became popular as a therapy, a method of cleansing, and a place for relaxation during the Victorian era, rapidly spreading through the British Empire, the United States of America, and Western Europe.
The oldest known saunas in Finland were made from 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 on 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. The first Finnish saunas are what nowadays are called savusaunas, or smoke saunas. These differed from present-day saunas in that they were heated by heating a pile of rocks called kiuas by burning large amounts of wood about 6 to 8 hours and then letting the smoke out before enjoying the löyly, or sauna heat. A properly heated “savusauna” gives heat up to 12 hours.
