International Sauna Congress from 24 – 27 October 2022 in Stuttgart!


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.

The XVIII International Sauna Congress

The XVIII International Sauna Congress has now been awarded to Germany for the period from 24 to 27 October 2022. It will be held in Stuttgart together with the world’s largest sauna trade fair, interbad. The event is held every four years by the International Sauna Association (ISA), based in Helsinki. The German Sauna Association (Deutscher Sauna-Bund) is responsible for the organisation and programme.

We expect that about 400 people will visit the congress.

Objectives of the Congress are

  • to establish forum for dialogue between representatives of the global sauna community
  • to encourage knowledge transfer and exchange of new insights from the fields of medicine, economics, technology, marketing and trend research
  • to facilitate healthy growth for the industry and its individual companies

Sauna – How to take a sauna bath?

Leave your clothes in the dressing room. Also remember to take off your eye glasses because the heath of the Sauna can damage them. Take off your watch also even if it is waterproof – you are here to relax, not to measure the time. You should also have a clean set of clothes to wear after the sauna. Take something to sit on, e.g. a small towel, into the sauna.


Global network of saunapeople

The International Sauna Association consists of four types of memberships.
We have the founding members, national members, supporting members and ou honorary members.

Gathering of all these dedicated sauna people is what makes it possible for the International Sauna Association to spread the important message of good sauna culture and continue the good work around the world.

It is also important for the International Sauna Association to protect the cultural history surrounding sweat bathing while also welcoming and supporting new sauna initiatives and ways to sweat baths.

All this is only possible thanks to our amazing members!
