A smile is an invitation - a sign ofwelcome
Smiling directly influences how others respond to you. The human brain prefers happy faces; it recognizes them faster than faces with negative expressions. In fact, research shows that if you smile at someone, it activates the “reward center” in that person’s brain.
It is also a natural response for the other person to smile back at you.
It seems that smiling is one of the most basic universal biological factors within the human condition which has a measurable effect on our overall well-being. It is probably one we acquired through evolution in order to get along with others.
Julia Roberts - The Oscar winner is still one of the highest-paid actresses in the biz. All she has to do is keep her larger-than-life "accessory" with her and she is surely to stay on top of her game.
A natural smile (which involves muscles around the eyes, unlike a fake smile) produces physiological feedback that makes the person smiling feel happier. Someone watching another person smile will involuntarily mirror the smile.
Even on the phone, when you “hear” someone smiling back at you, it makes you feel happier. Thus a feedback loop kicks in as the body produces neurochemicals correlated with happy feelings.
For example, research published in the journal Political Psychology used automated face-recognition technology to create a “smile index” for politic candidates’ faces. The study found that a greater “smile index” correlated to a greater vote share for Australian candidates in the 2000 and 2004 elections, smiling increased vote share by 5.2 percentage points in Australia.
