Corinna Treitel's research focuses on science, medicine, and popular culture. She has published on everything from occultism and modernism to natural foods, organic farming, and biopolitics. Her current research investigates the puzzle of health consciousness. Health consciousness is that voice in your head that tells you to brush your teeth, exercise, and eat lots of fresh fruits and vegetables. How did it get there? Treitel’s book uses the German case to explore a group of movements—medical enlightenment, popular hygienic education, Lebensreform (life reform), health communication, and wellness—that worked hard over the past 200 years to put it there.
