Sauna — Good or Bad?

Had a quick look in the search bar for "Sauna" not much discussion, Anyway anyone have any experiences with either Traditional hot rock or Infrared Sauna usage to take the edge off the "T"

 

We have a saying here in Finland, where more or less everybody have their own sauna in their homes. 'If sauna and tar don't cure you, it will be death'

Yes, sauna can help, because it relaxes you -> T can go down as well. And especially if you have muscle tension related T.
