Exercise and the Placebo Effect

Cleaning hotel rooms is a strenuous business. However, when Alia Crum and Ellen Langer talked to 84 maids, most were under the impression that they did not get enough exercise. Furthermore, when they were measured for tests such as BMI and blood pressure, their results were typical of couch potatoes. The researchers let half the group in on the knowledge that they were getting more than enough of a daily workout and kept the rest in the dark. After a month results showed the former group were healthier on every single one of the objective health measurements tested - despite claiming to have been doing no more exercise or to have changed their diet. The study raises the possibility that mindset alone can influence our metabolism. Christopher Shea in the New York Times and Ben Goldacre in The Guardian have articles discussing the original paper.
