The Art and Science Behind Smiling

Did you know the average person smiles about 13 times a day? For children, that number jumps to as many as 400 times a day! While a smile might seem like a small gesture, it holds significant power for both the person smiling and those around them. In a recent study, researchers found that individuals who smile are often seen as healthier and more attractive, even more than those who are the “right” weight or wearing makeup.

When you smile, your brain releases four hormones: neuropeptides, endorphins, serotonin, and dopamine. This flood of hormones boosts your mood and can have various beneficial effects.

Let’s break down what happens in your brain when you’re happy. Neuropeptides are small molecules that help neurons communicate, spreading feelings like happiness, sadness, and even pain throughout your body. There are around 100 different types of neuropeptides, which can trigger reactions that relieve stress and create a sense of calm.

Endorphins, known as our ‘happy’ hormones, are released by the pituitary gland. You might have heard about an ‘endorphin rush,’ which happens when these hormones respond to stress and pain, helping to block those feelings and control your emotions. They also lower your heart rate and blood pressure, making you feel more relaxed.

Dopamine plays a crucial role in motivation and productivity. It travels from the ventral tegmental area to the brain’s pleasure centers, creating feelings of joy. Besides making you feel good, dopamine also sends signals to your muscles, aiding in movement.

Serotonin, found in the brain stem, affects your mood by reducing depression and regulating anxiety. Released when you smile, serotonin helps stabilize your mood. It’s also found in blood platelets, aiding in wound healing by narrowing arteries and forming blood clots.

Smiling can significantly improve your health. It lowers your heart rate, meaning your heart isn’t overworked, and reduces stress. A study confirmed that holding a smile during a stressful situation can benefit your heart. Endorphins released by smiling also help lower blood pressure.

Regarding mental health, psychologists have found that forcing a grin when you’re feeling down can instantly boost your mood. In fact, one smile can provide the same level of dopamine as up to 2,000 chocolate bars, explaining the saying “grin and bear it.”

Smiling is contagious because of mirror neurons in the brain that prompt us to imitate others. So, smiling not only makes you feel better but can also brighten the day for those around you.

Humans aren’t the only ones who respond to smiles; some pets like dogs, cats, and horses can sense and respond to your good mood. Smiling is one of the first facial expressions babies make, and ultrasound scans have shown that babies even smile in the womb!

There are 19 different types of smiles, though only six are genuine expressions of happiness. Others include polite smiles, which only involve the mouth, and embarrassed smiles, where the lips are kept tightly shut.

While it takes more muscles to smile than to frown, smiling is easier because we’ve mastered the muscles involved in grinning.

So, keep smiling! Boost your hormones and enjoy the daily benefits.
