A smile is the least common denominator of communication!
Smile all over the world
All over the world the facial expression of smiling is nearly the same. Nowadays scientists concede this point to old Darwin. Smiling is like other emotions organised from the brain and expressed facially.
So there have to be the same basic forms of facial expressions of feeling happy throughout the world. Admittedly there are some cultural differences which regularise the scale of the shown emotions - so the smiling reactions of some people may seem a bit exotic to each other.
Anyway smiling belongs to the universal human vocabulary!
Your smile development
Smiling is hereditary! It’s a genetic disposition to sense and express happiness. Even children who are born blind and deaf smile like all other children. When a baby is born its facial musculature is completely developed and ready for action. So in the early babyhood there are the same characteristic forms of facial expressions which are shown from adults. Even a new born smiles an unspecific smile and at an age of three to four weeks this smile gets a bit more selective - it helps to forge close interpersonal links with the attachment figure. Babies and little children express their emotions avowedly.
Schoolchildren start to adjust the express of their feelings to the expectations of their social partners and an adult smiling face is a social ‘amplifier’ and acts as an indicator for social competence.
Smiling is an intelligent start of international communication - irrespective of nationality, colour of skin, wealth, gender, age, and even religion.
And you even get an extra bonus again:
Smiling has a stimulating and therewith invigorating effect on the whole human organism. Besides protecting your heart effectively, humour boosts your immune system, is conductive to each healing process and is even a great method for reducing stress and enhancing relaxation.
And the brains of smiling people are better provided with oxygen because the use of the facial muscle while smiling enhances those blood vessels which transport the oxygen to the brain. Probably that’s one of the reasons why Nobel Prize Laureates smile that much.
And as an extra present: While smiling your body distributes the ‘lucky-hormone’ endorphin, so we can actually smile us happy.
