Ramazzini, along with Francesco Torti, was an early proponent of the use of cinchona bark (from which quinine is derived) in the treatment of malaria.

His book on occupational diseases, De Morbis Artificum Diatriba (Diseases of Workers) outlined the health hazards of chemicals, dust, metals, repetitive or violent motions, odd postures, and other disease-causative agents encountered by workers in more than fifty occupations.

[4] [5] He proposed that physicians should extend the list of questions that Hippocrates recommended they ask their patients by adding, "What is your occupation?".

In his Oratio given in 1711, he suggested that "it is much better to prevent than to cure, and so much easier to foresee future harm and avoid it rather than have to get rid of it after having fallen prey".

[5][9] In a lifestyle article "Sitting can lead to an early death", the writer acknowledged Ramazzini's pioneering study of this field in the 17th century.
