The Importance of a Smile

What is the importance of a smile? Not only will your smile give you health and emotional benefits, but you will also be playing your part in spreading joy around the world.

Many of us are aware of the latest health fads; the ketogenic diet, super-foods, and even Netflix and chill (I’m sure that has health benefits), but how often do we pay attention to the time-honoured humble smile? It’s been around for centuries, so shouldn’t we be giving it the attention it deserves?

Personally, I smile a lot. My nickname, at my first place of work in my late teens, was ‘Smiler’. For someone who had been nicknamed  ‘Ostrich’  by the kids in my street, due to being tall and skinny – ‘Smiler’ was a vast improvement.

My Grandmother’s smile reached right into my heart. Each time her beaming face shone at me it was as if she’d scooped me up in a warm blanket of love. My Grandfather had a cheeky grin and loved a joke. I think they nurtured my propensity to smile and I’ve used it often on my life’s journey.

Keep smiling quote on a post-it note

Life can throw us a few curve balls now and again, and being able to smile our way through them can be a useful tool in our toolbox.

Now, as I travel the world – a smile is always on the packing list – it certainly makes communication easier and when you are doing something that you love, it’s easy to keep your smile in tip top condition.

16 Reasons Highlighting the Importance of a Smile.


A gesture we all understand across the world is a smile. It is something we all do innately and is not something that we learn to do. For example, babies who are blind, smile at their parent’s voice.

In the words of the late writer and poet, William Arthur Ward;

A warm smile is a universal language of kindness.

Being on the road for so long now and having visited so many different countries, we have used this valuable commodity on many occasions.

When neither of you speaks a common language, a smile and a laugh go a long way in getting along.  It’s the universal language, so they say, and for us, it has definitely gotten us out of some tricky situations.

Smiling quote with an old woman smiling
In most countries, a smile conveys warmth and friendliness and tells the other person that, ‘We come in peace!’

That said though, how we perceive a smile is learnt and that perception can vary between cultures. Charlene Solomon writes an interesting article on, The Cross-cultural Implications of Smiling, surmising that countries like the United States, Canada, and Australia have smiling cultures whereas countries like China, Russia, and Japan do not.

This is something to bear in mind if you are travelling to other countries. Throughout our travels, in Europe, we have had many a time where a smile has warmed our hearts and made us feel welcome, even when we shared no common language.

However, there have also been occasions where our smiles have been met with stone-cold faces. Sometimes this is an individual thing, but can also be reflective of a specific culture.

In the main though, smiling brightens the day of most of us across the world.

2. Smiling Encourages Positive Thinking

Studies have shown that smiling when doing something that you don’t necessarily like, helps you to feel much more positive about the task at hand.

Darwin originally developed this theory, which is now known as the Facial Feedback Response Theory What it basically means, is that your brain recognises the movement of your facial muscles, so when they are in the ‘smile’ position it thinks that you are happy which helps you to think positively about the situation.

So next time you want to lift that optimism level a notch, break out a full-bodied beam. One that causes the sides of your mouth to curl up and the skin around your eyes to crinkle.

That way, your brain gets the message that you are happy and it will help you have a more positive outlook.


Ladies, did you know that the most important thing in your makeup bag is your smile?

Studies have found that your smile has a bearing on your perceived atrractiveness.

The study, ‘Something to Smile About‘, found, that “the evaluation of attractiveness is strongly influenced by the intensity of a smile expressed on a face: A happy facial expression could even compensate for relative unattractiveness.’

Therefore, it’s not so much the colour of our lipstick, but what our lips are doing .

Another article discusses how a dating app, Coffee and Bagel, found that women who smiled and tilted their head to the side in a photo, appeared even more attractive!

Something to bear in mind for your profile pics and for those of you using dating sites and apps.

Smiling not only makes you look more attractive but also healthier. What’s even more interesting, and this is especially for those more mature ladies among us, researchers at Swansea University found that,

‘ …while younger adults look healthier when they smile, older adults look much healthier. A smile was a more important cue than how old the face appeared to be.’ … Scientific proof that a smile really is the best accessory. – Dr. Alex Jones


Most often, when you smile at someone, they smile back. Little neurons in our brain are wired to imitate another person smiling as it helps us assess how that person is feeling. We are also emotional human beings and most of us want to reciprocate.

5. The Importance of a Smile for Happiness

When we smile, even if it’s fake, our brain releases serotonin, which is a natural anti-depressant. Along with the release of endorphins, our brains are pumping us full of these natural ‘drugs’ and getting us high on happiness.

Ron Gutman, the author of, Smile: The Astonishing Powers of a Simple Act, gave a fascinating Ted Talk, on the Hidden Power of Smiling.

He refers to studies that have found a smile to be as stimulating as 2000 bars of chocolate, meaning that the pleasure of smiling far outweighs that from chocolate.

Personally, I think they may have used the wrong chocolate bars. That said, if smiling made me feel as good as chocolate, it would definitely save the waistline. The day a smile comes with a smooth, creamy, delicious taste too, then I might buy into that piece of research.


Studies have found that smiling makes you more attractive and as a consequence, you are more likely to be thought of as intelligent.

A more recent marketing study suggests that the size of your smile can affect that perception. They found that a subtle one makes you look intelligent compared to a wide one.

A wider grin, although not so good for the appearance of intelligence, suggests to others,  that you are warmer and kinder.

Apparently, Facebook photos of those with wider, broader smiles are shared twice as much. However, if you are trying to raise money through Crowdfunding, go for a subtle smile as people are more likely to donate and give more if they see you as more competent.

7. Smiling is Free

There aren’t too many valuable assets today that don’t have a price tag attached to them. This is one area that does not need your budgeting attention. So, don’t be frugal with your smiles, use them to your heart’s content.

8. The Importance of a smile on Your Immune System

This one is a great example of the importance of a smile in connection with your health. Smiling releases endorphins (feel-good chemicals) which in turn, causes a reduction of cortisol (your stress hormones). As a result, this means that your body is more effective in fighting off infections. To get the most benefit it should be a genuine one and not a fake one – think of something that makes you laugh or something that genuinely makes you smile and your immune system will get a welcome boost.


So many of us seem to be time-poor, so this is one thing that won’t be a drain on that finite resource. It can take less than a few seconds but can brighten someone’s whole day and improve your health and wellbeing.


If you smile, other people automatically think you are more likeable and warm towards you much quicker.

One study looked at the smiles of college students in their yearbook photos, measured their smiles and then assessed their lives in later life. The study concluded, that those with bigger smiles went on to have happier and longer marriages.

We all like being liked and just a simple act of smiling a little more can make a big difference in how you get along with others.


This simple act does nothing but improve your environment. No trees are cut down, no plastic is wasted and a smile is completely reusable, time and time again. Smiling is sustainability at its best!


Smilers are perceived as more confident and sociable.  Ultimately that means that the more you smile, the more likely you will be picked for promotion.

Next time you are feeling stressed, pop on a smile to let the tension ease away.

The aptly named, Grin and Bear it study, showed that if a person smiles and then undergoes a stressful activity, they have a lower heart rate and their recovery from the stress is quicker.

Again, these results achieved the most success when it was a genuine smile, but just having the face in a smiling pose, decreased the stress in comparison to no smile at all.


It’s quite possible that smiling could add quite a few years to your life. Just another testament to how smiling and positivity are so good for you and your wellbeing.

The wider your smile and the more laughter lines you have, the longer you are likely to live. They measured the smiles of baseball players and then compared these with their lifespan. The study concluded that smiling could add five to eight years to your life.

It’s such a simple thing to do and has such huge gains.  So get those wide grins going and crinkle up those eyes for a longer lifetime of fun and happiness.


Smiling while experiencing pain lessens the effect of the pain. Studies show that pain can be reduced by up to about 40%. Not a bad natural remedy to have available right there on tap.


When someone smiles at you, you get a kind of warm fuzzy feeling. That happens because our brains see it as a reward.

So it doesn’t just feel good for you, that great feeling transfers on to someone else.  In addition, when they smile back at you, you get an extra boost too! …and so it goes on. The gift that just keeps on giving.

‘We shall never know all the good that a simple smile can do.’

 – Mother Theresa

So, go ahead and give yourself a gift right now. The more you do it, the more it becomes a natural habit.

Smiling is not only wonderful for your own wellbeing, but so many other’s welfares too. Due to its remarkable ripple effect, we have the power to spread joy and change the world, one smile at a time.
