The power of engagement?
Is there truly a piece of mind over matter in creating healthy people?
The NYtimes has an an interesting piece where a couple of Harvard psychologists turned awareness of healthy behavior into meaningful improvement in health metrics.
At the start of the study, Langer and Crum quizzed 84 maids at seven carefully matched hotels about how much exercise they got. Fully a third of the women said they got no exercise at all, while two-thirds said they did not work out regularly. Langer and Crum took several measures of the women’s basic fitness levels, which indicated that they, indeed, had the poor health of basically sedentary people. Then just over half the women were told an unfamiliar truth: cleaning 15 rooms daily — pushing recalcitrant vacuum cleaners, scrubbing tubs, pulling sheets — constitutes more than enough activity to meet the surgeon general’s recommendation of a half-hour of physical activity daily. The researchers even provided specifics: 15 minutes of scrubbing burns 60 calories, 15 minutes of vacuuming burns 50. The basic message and the details were then posted in the maids’ lounges in the hotels where the 44 women worked, to serve as reminders, while a control group was left in the dark.
A month later, Langer and Crum checked back with the women to find, as they reported in the February issue of Psychological Science, remarkable results. The average study-group maid had lost 2 pounds, while her systolic blood pressure had dropped by 10 points; by all measures the 44 women “were significantly healthier.” Yet there were no reported changes in behavior, only in mind-set, with the vast majority of the women now considering themselves regular exercisers.
This has some interesting correlations to other stories of expectation, notably the Pygmalion in the Classroom example of a teacher with high expectations for a “gifted” class of randomly selected students ended up with a group of high achievers at the end of the year.
