Pyrotherapy

Pyrotherapy (artificial fever, therapeutic fever) is a method of treatment by raising the body temperature or sustaining an elevated body temperature (caused by a fever). In general, the body temperature was maintained at 41° Celsius(105° Fahrenheit) . Many diseases were treated by this method in the first half of the 20th century. In general, it was done by exposing the patient to hot baths, warm air, (electric) blankets, or high-frequency steam.
