What does sauna mean?
A sauna is a room or building where people sit in heat to sweat, traditionally associated with Finland and also found in other Nordic countries. In English, the word can refer both to the physical space and to the practice of using it. Saunas may use wood-burning or electrically heated stoves and may include steam, although the exact temperature and humidity vary greatly. Taking a sauna is commonly associated with relaxation, bathing, and social interaction, but it can also be part of a vigorous exercise routine. In Finland, the sauna has broader cultural significance and is associated with cleanliness, wellbeing, and hospitality. Outside Finland and the Nordic countries, the term is widely recognized through international travel, wellness culture, and the popularity of Finnish and Scandinavian sauna experiences.
