Smiling is Nature’s Stress Reducer, it can “Actually Influence Our Physical State”
Just grin and bear it! At some point, we have all probably heard or thought something like this when facing a tough situation. But is there any truth to this piece of advice? Feeling good usually makes us smile, but does it work the other way around? Can smiling actually make us feel better?
In a study forthcoming in Psychological Science, a journal of the Association for Psychological Science, psychological scientists Tara Kraft and Sarah Pressman of the University of Kansas investigate the potential benefits of smiling by looking at how different types of smiling, and the awareness of smiling, affects individuals’ ability to recover from episodes of stress.
“Age old adages, such as ‘grin and bear it’ have suggested smiling to be not only an important nonverbal indicator of happiness but also wishfully promotes smiling as a panacea for life’s stressful events,” says Kraft. “We wanted to examine whether these adages had scientific merit; whether smiling could have real health-relevant benefits.”
Smiles are generally divided into two categories: standard smiles, which use the muscles surrounding the mouth, and genuine or Duchenne smiles, which engage the muscles surrounding both the mouth and eyes. Previous research shows that positive emotions can help during times of stress and that smiling can affect emotion; however, the work of Kraft and Pressman is the first of its kind to experimentally manipulate the types of smiles people make in order to examine the effects of smiling on stress.
The researchers recruited 169 participants from a Midwestern university. The study involved two phases: training and testing. During the training phase, participants were divided into three groups, and each group was trained to hold a different facial expression. Participants were instructed to hold chopsticks in their mouths in such a way that they engaged facial muscles used to create a neutral facial expression, a standard smile, or a Duchenne smile. Chopsticks were essential to the task because they forced people to smile without them being aware that they were doing so: only half of the group members were actually instructed to smile.
