Often described as a beguiling and mysterious expression, it has led to countless interpretations and speculations. What are the facts and latest scientific evidence on your smile?

Believe it or not, [we are actually born smiling.](https://www.waldenu.edu/online-bachelors-programs/bs-in-psychology/resource/the-power-of-smiling#) With the advancement of 3D ultrasound technology, doctors and medical practitioners have been able to identify that developing babies smile in the womb.

## What is the science behind your smile?

Smiles are universally recognized as expressions of [happiness, ](https://richwoman.co/article/happiness-how-to-break-free-from-the-holiday-blues-and-be-happier)[joy](https://richwoman.co/article/life-is-better-with-joy-finding-joy-in-every-moment-of-life-to-break-free-from-the-cycle-of-a) and[ kindness](https://richwoman.co/article/the-power-of-positive-intentions-what-is-the-real-meaning-of-kindness). Smiling can brighten our day and make us feel more connected to others. But the power of a smile goes beyond just a pleasant facial expression; it has a profound impact on our brain and mood.

We looked into countless[ statistics and scientific evidence that highlight the significant role your smile](https://www.psychologicalscience.org/observer/the-psychological-study-of-smiling) plays in setting the mood and affecting the brain. Here are just a few findings:

**Hormonal Impact**: When you smile, your brain releases a cocktail of hormones, including endorphins and serotonin. Endorphins are your body’s natural painkillers and mood elevators, while serotonin contributes to overall feelings of well-being and happiness. This hormonal surge can reduce stress and anxiety and promote a positive mood.

**Cortisol Reduction**: Smiling has been shown to lower cortisol levels, the hormone associated with stress. Studies have found that even a forced smile can help reduce stress. When you genuinely smile, your brain interprets it as a sign of safety, leading to a reduction in stress levels.

**Boosting Immunity**: The positive impact of smiling on your mood and stress levels can, in turn, strengthen your immune system. Lower stress levels are associated with better immune function, making you more resilient to illnesses.

**Frequency of Smiling**: On average, children smile around 400 times a day, while adults smile only about 20 times a day. This statistic highlights how our smiling habits change as we grow older, potentially impacting our mood and overall well-being.

**Social Connections**: A study published in the journal “Psychological Science” found that people who smiled in their Facebook photos were more likely to be married and have a higher level of well-being compared to those who didn’t smile.

**Workplace Impact**: Research conducted by the University of California, Riverside, revealed that employees who smile more at work tend to receive higher customer satisfaction ratings and are more likely to be promoted.

**Perceived Attractiveness**: Smiles also influence our perception of others. A study published in the journal “Emotion” found that people are viewed as more attractive, reliable, and competent when they smile.

## Is your Smile contagious?

Have you ever noticed how a warm smile from someone can instantly brighten your day? It’s not just a coincidence; there’s a powerful, contagious force behind smiles that can [spread joy and positivity ](https://richwoman.co/article/emotional-resonance-the-paradox-of-letting-go-so-you-can-thrive)like wildfire. Smiles are universal expressions of happiness and friendliness and they have the remarkable ability to influence the emotions and moods of those around us.

**Contagious Nature**: Smiles are contagious. When you smile at someone, they are more likely to smile back. This simple exchange of smiles can create a positive feedback loop, enhancing the mood of both individuals.

**Creating Positive Environments**: In social settings, a smile can set the tone for interactions. When you smile upon entering a room or engaging in a conversation, you create a welcoming and friendly atmosphere, making it more likely that others will respond in kind.

**Stress Reduction**: When you smile during challenging situations, it can help diffuse tension and reduce conflict. Your positive expression sends a signal that you are open to cooperation and resolution, ultimately improving the mood and outcome of the situation.
