Wash hands and take a bath, with the naked eye we can see physically clean. But it turns out, in order tohave a greater impact. Wash hands and shower are also on the thoughts and feelings, in addition to providing a positive impact on physical health but also the psychological effect. 

The results of the study at the University of Michigan researchers are able to explain the United States to help their hands “clean up” bad feelings wash. Hand washing, bathing,thinking about it, tidy up, you can reduce or eliminate feelings of immorality, not a promotion,or doubt.

“The experience of the physical body to detoxify can also provide a basis for abstract mentaltoxins and presents a very strong aspect of the metaphor,” to eliminate a researcher said Spike Lee.

The researchers interviewed a group of respondents, the morality of their own and other people will be assessed in different situations. They were asked to think past immoral actsand their error rate was determined by means of psychological tests.

Some were tested in a clean, and the others were tested in the dirt. In another experiment, therespondents have access to participate in hand washing with antiseptic, and an opportunity to participate in the good works after the experiment.

The researchers found, was in a dirty room, the respondents to judge the morality of othersworse off than when they’re in clean room. Then they wash their hands. Apparently reduced their debt.
