This study is of interest because it evaluates scientifically how housekeeping's processes may impact our thinking and health, and vice versa. While it mentions the placebo effect, the effect might just be more complex and real than some suppose. This kind of research should rightly create buzz. Does cleaning provide exercise? Yes. Can this make us healthier? Yes – but the study also shows the importance of a positive attitude. The article makes the statement, “actual behavior did not change” between those who were told the value of exercise versus those who were not, but we submit that behaviors could have been subtlety affected – certainly attitude and behavior are intertwined.
