Speleotherapy

Speleotherapy (Greek σπήλαιον spḗlaion "cave") is the respiratory therapy involving breathing inside a cave.

A 2001 Cochrane summary concluded that as no trials had been done, there is no evidence to determine whether breathing air inside a cave is useful in treating asthma.

There are claims of improvements in the breathing of miners in Roman and medieval times. Modern use of this therapy started in Germany by Karl Hermann Spannagel.
