Our story starts in the mid-1800s with a French scientist named Guillaume Duchenne. He was curious about how our faces show emotions, so he used electrical currents to stimulate different facial muscles. Through his experiments, he discovered which muscles are responsible for expressions like fear, sadness, and joy. Interestingly, he found that only two muscles create a genuine smile: one under our eyes and another on the side of our cheeks. When these muscles work together, it looks like your eyes are smiling too, and this is called a “Duchenne smile.”
We know that feeling happy can make us smile, but can smiling actually make us feel happier? Inspired by Duchenne’s findings, Charles Darwin proposed that our facial expressions can influence our emotions. This means that if you look scared, you might feel more frightened, and if you genuinely smile, you might feel happier. This idea is known as the facial feedback hypothesis.
Fast forward to the 20th century, American psychologist Paul Ekman studied the smiles of women watching movies. He noticed that those who showed genuine Duchenne smiles, engaging the muscles near their eyes, reported feeling more amused and happier than those who didn’t smile. This led to the interesting conclusion that smiling when we’re happy is a natural response.
In a more recent study, some participants received Botox treatments that paralyzed the muscles responsible for frowning. These participants couldn’t show sad or distressed emotions on their faces, and they reported feeling happier than those who had different cosmetic procedures.
Even fake smiles have their benefits. In one study, participants were asked to fake a smile while doing a stressful task. Those who smiled had lower heart rates during the recovery period compared to those who kept a neutral expression. This suggests that forcing yourself to smile can actually help you feel happier and reduce stress.
In summary, smiling can be a powerful tool for boosting your mood and reducing stress. So, the next time you’re feeling down, try grinning and bearing it—you might just find your sadness and stress fading away.

Explore the muscles involved in different facial expressions. Use a mirror to observe your face as you mimic expressions of happiness, sadness, and fear. Try to identify the muscles that are activated with each expression, especially focusing on the muscles used in a Duchenne smile. Discuss your observations with a partner.
Conduct a simple experiment to test the facial feedback hypothesis. Spend a few minutes smiling genuinely and then a few minutes with a neutral expression. Record your mood before and after each session. Share your findings with the class and discuss whether smiling influenced your emotions.
In groups, create short skits where characters use different facial expressions to convey emotions. Perform these skits for the class, and have your classmates guess the emotions being portrayed. Reflect on how facial expressions can impact both the person expressing them and those observing.
Learn about various stress reduction techniques, including smiling. Practice these techniques in class, focusing on how smiling can help lower stress levels. Discuss which methods you found most effective and why.
Research a study related to smiling and emotions, such as the Botox study mentioned in the article. Prepare a short presentation summarizing the study’s methods, findings, and implications. Present your findings to the class and lead a discussion on the potential benefits of smiling.
Our story begins in the mid-1800s when French scientist Guillaume Duchenne studied emotional expressions by stimulating various facial muscles with electrical currents. He identified which muscles are responsible for expressions of terror, sadness, and joy. While many muscles in our face can simulate a smile, only two produce a genuine smile—one under our eyes and another on the side of our cheeks. This phenomenon, where it appears that your eyes are smiling too, is known as a “Duchenne smile.”
Joy and happiness can lead to genuine smiles, but can smiling itself make us feel happier? Inspired by Duchenne’s work, Charles Darwin suggested that our facial movements influence our emotional experiences—there’s a feedback loop where looking scared can make you feel more fearful, and a genuine smile can enhance happiness. This concept is known as the facial feedback hypothesis.
Fast forward a century, and American psychologist Paul Ekman monitored the smiles of a group of women while they watched a series of movies. Those who smiled genuinely (a Duchenne smile) and engaged the muscles near their eyes reported feeling significantly more amused and happier than those who didn’t smile. This led him to the remarkable conclusion that we smile when we’re happy.
In a more recent study, one group of participants received Botox treatment for frown lines, which paralyzed the corrugator muscles in their brow. These participants couldn’t express sad or distressed emotions on their faces, and their reported positive mood was significantly higher than that of other participants who received different cosmetic procedures.
Beyond genuine smiles and frown-muscle paralysis, there’s also hope for our fake smiles. One study found that when participants were asked to fake a smile while completing a stressful activity, they had lower heart rates during a stress recovery period compared to those who maintained a neutral expression. This suggests that forcing yourself to smile can indeed make you feel happier.
In summary, if you grin and bear it, it’s likely that your sadness and stress will diminish over time. If you enjoy this content, consider subscribing to BrainCraft for a new brainy video every Thursday!

Feedback – Information about reactions to a product, a person’s performance of a task, etc., used as a basis for improvement. – The feedback from our facial expressions can affect our emotions, as suggested by the facial feedback hypothesis.
Psychologist – A professional who studies mental processes and behavior and applies this knowledge to help individuals improve their mental health. – The psychologist conducted an experiment to see how different types of music affect people’s emotions.
