Does cleaning your hands make you happy? A New study out of the University of Cologne says it makes most people feel better about themselves. Dr. Kai Kaspar says people who cleaned their hands after failing a task were more confident they could complete it the next time around. Dr. Kaspar split 98 people into groups. When 2 groups failed at a task he would have one group wash their hands before trying it again. The study found that the hand washers were much more optimistic they could complete the task.
Previous research found that hand washing is physically and emotionally cleansing. A team from the University of Michigan reported that 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.
