International Sauna Association (ISA)
The International Sauna Association (ISA) is an association of national and other sauna societies, organisations and private people. It was founded in 1958 with the office in Germany . After 20 years quite slow activities it was reborn in 1977 in Helsinki Finland and the office was agreed to be in Helsinki.
The founding members were Austria , Germany , Finland and Japan and they are continuously members. Besides those there are 20 other members including all the important sauna countries. The President has been all these years from Finland.
ISA and its members shall pursue the goal of publicizing the sauna and promoting its use on a global scale by rallying supporters of sauna activities in different countries.
This goal is served e.g. by acceptance of the Definition of Sauna recorded in Aachen , Germany 1999 as well as promoting the scientific studies of the sauna from e.g. such viewpoints as social history, folklore, medicine and technology. A particular emphasis is given to the collection and compilation in archives of the results of such scientific studies as well as other written material on sauna.


Sauna aid
Sauna Aid is a multicountry initiative, sponsored by the International Sauna Association (ISA), to provide movable sauna facilities and supportive services to people facing natural and man-made disasters.
During the 2011 Fukushima tsunami and nuclear plant accident, ISA and the Japanese Sauna Society maintained a tent sauna for five weeks and used it for decontamination and cleaning of over a thousand locals.
Sauna Aid is now focused on the war in Ukraine. The sauna, or laznia/banya, as it is known among Ukrainians, is an important part of everyday life and provides a means of hygiene, stress relief, socialization, psychological comfort, and social identity. It is not considered a luxury, nor is it only about cleanliness. It is a social event that brings together the young and the old, the rich and the poor and promotes peace and a common sense of humanity. Ukrainians call the banya their “second mother”.
