The role of hydrotherapy in European insanity apartments at the beginning of the twentieth century

The report aims to treat the use of hydrotherapy as a method of treating madness in European psychiatric hospitals of the early 20th century. It takes its cue from a scientific article that appeared in three episodes in 1913 in an Italian medical journal (the "Gazzetta Medica Lombarda"): << The warm lukewarm bath as a sedative >> by dr. Carlo Pontiggia, psychiatrist in the Mombello mental hospital near Milan. The report also mentions the role of the lukewarm bath and hydrotherapy in general in the treatment of mental disorders of the time through the analysis of some treatises by illustrious Italian and foreign psychiatrists.
