Speleotherapy (Greek σπήλαιον spḗlaion "cave") is a proposed respiratory therapy involving breathing inside a cave.[1]

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.[1]

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.[2]
