A Kiuas is a traditional Finnish sauna stove that heats the sauna room by burning wood or using electricity. It is designed to create a hot and steamy environment, essential for the sauna experience. The stove heats stones placed on top, which then radiate heat and can be splashed with water to produce steam, increasing humidity. In Finnish culture, the Kiuas plays a central role in sauna rituals, promoting relaxation and social interaction. Saunas are often used for health benefits, including improved circulation and stress relief, making the Kiuas an important element in Finnish wellness practices.
