Grin and bear it -- smiling facilitates stress recovery

31.07.2012
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.

For the testing phase, participants were asked to work on multitasking activities. What the participants didn't know was that the multitasking activities were designed to be stressful. The first stress-inducing activity required the participants to trace a star with their non-dominant hand by looking at a reflection of the star in a mirror. The second stress-inducing activity required participants to submerge a hand in ice water.

During both of the stressful tasks, participants held the chopsticks in their mouth just as they were taught in training. The researchers measured participants' heart rates and self-reported stress levels throughout the testing phase.

The results of the study suggest that smiling may actually influence our physical state: compared to participants who held neutral facial expressions, participants who were instructed to smile, and in particular those with Duchenne smiles, had lower heart rate levels after recovery from the stressful activities. The participants who held chopsticks in a manner that forced them to smile, but were not explicitly told to smile as part of the training, also reported a smaller decrease in positive affect compared to those who held neutral facial expressions.

These findings show that smiling during brief stressors can help to reduce the intensity of the body's stress response, regardless of whether a person actually feels happy.

"The next time you are stuck in traffic or are experiencing some other type of stress," says Pressman, "you might try to hold your face in a smile for a moment. Not only will it help you 'grin and bear it' psychologically, but it might actually help your heart health as well!"

Im Focus: Better thermal conductivity by adjusting the arrangement of atoms

Adjusting the thermal conductivity of materials is one of the challenges nanoscience is currently facing. Together with colleagues from the Netherlands and Spain, researchers from the University of Basel have shown that the atomic vibrations that determine heat generation in nanowires can be controlled through the arrangement of atoms alone. The scientists will publish the results shortly in the journal Nano Letters.

In the electronics and computer industry, components are becoming ever smaller and more powerful. However, there are problems with the heat generation. It is...

Im Focus: Megakaryocytes act as „bouncers“ restraining cell migration in the bone marrow

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.

Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...

Im Focus: Artificial neural network resolves puzzles from condensed matter physics: Which is the perfect quantum theory?

For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.

Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...

Im Focus: Extremely hard yet metallically conductive: Bayreuth researchers develop novel material with high-tech prospects

An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".

The possibility of finding a compound that was metallically conductive, super-hard, and ultra-incompressible was long considered unlikely in science. It was...
