Healthy through Confidence. Placebos are the pills that don't work? Just a trick by doctors? Antje Maly-Samiralow radically challenges this widespread notion. The journalist presents "The Placebo Principle," the first popular science book that reveals astonishing connections between the psyche and the healing power of the body. Science proves that even those who take placebos can benefit when their brains are conditioned for healing success. What heals, among other things, is confidence. And this can trigger powerful placebo effects. Negative suggestions, on the other hand, can ignite nocebo effects, with sometimes devastating consequences for the health of those affected. The author also outlines ways in which everyone can positively influence their health and avoid unnecessary nocebo effects.
