Aren’t you satisfied with you decision? Did you fail to solve a task? Wash your hands afterwards to feel much better.
Researchers found that the ritual of cleaning makes us more optimistic after failure, but “while physical cleansing after failure may eliminate negative feelings, it reduces the motivation to try harder in a new test situation.” – dr. Kai Kaspar from University of Cologne explained.
A team of psychologists from the University of Michigan found that handwashing is physically and emotionally cleansing. The simple act of washing hands made people feel more comfortable about the decisions they had made. They found that people who washed immediately after making a difficult decision were happier with their choice compared with those who didn’t.
