A little bit of history
We’ve known about salt therapy benefits for a while now. In 1843, Polish doctor Feliks Boczkowski observed that salt miners from Wieliczka Salt Mines didn’t experience respiratory diseases like other miners. Then, during World War II, German doctor Karl Hermann saw the same with his patients, who were hiding in a salt mine from bombs. They noticed that inside these salt caves, their patients’ respiratory health was greatly improved from being there.
