What’s in a Smile?

A smile is one of the most powerful ways we have to connect with other people. Having a smile you are confident to share can change your life in unexpected ways! Here are 10 amazing facts about a smile I have discovered in my research.

1) A smile is the only outward way we have to express positive emotions such as joy, love, and curiosity.

2) You can see a real smile in someone’s eyes. Contracting the eye muscles is the marker of a true smile (called a Duchenne smile by scientists). Which of these celebrities is giving a true smile?

3) A true smile changes your brain by activating the left frontal portion of the brain – the very same part activated during emotions of happiness, contentment, and joy. Smiling creates a great feedback loop of happiness!

4) A true (Duchenne) smile in a yearbook photo can predict your happiness 25 years later. Researchers have found people who were smiling in their college yearbook photos felt more competent, experienced fewer negative emotions, were more likely to be happily married, and were more satisfied with their lives 25 years later.[1]

5) Smiling can make you live longer. A study of photos of major league baseball players from the Sporting News Baseball Register compared non-smilers, partial smilers, and true (full) smilers. Controlling for other factors such as weight, education, and marital status, they found that full smilers, on average, lived 7 years longer than the non-smilers! [2]

6) Smiling and experiencing positive emotions makes you smarter. In a study of 6 and 7 years olds, the children were asked to take a portion of a standardized intelligence test after being read one of two stories. The stories were the same, but one ended on a sad note, while the other had a happy ending. The children who heard the happy story got 50% more questions correct than the children who heard the sad story. [3]

7) Smiling can create more success at work. Psychologists observed people at their jobs and found that those who smiled more often were rated more highly by their employers and made more money. [4]

8) Smiling can get you hired. Many companies, especially for jobs where you interact with people such as sales, note how often a candidate smiles during a brief interview as a screening tool. At Holiday Inn, you must smile at least 4 times in an interview in order to be hired. [5]

9) Smiling faces are more attractive. Researchers used computer graphics to manipulate identical faces to be more attractive and/or express more happiness with a smile. Less attractive, but smiling faces were seen just as or even more attractive as the more attractive, but non-smiling faces. All faces were seen as better looking when smiling. [6]

10) People with attractive smiles are perceived to be more successful, kinder, more intelligent and happier than people with less attractive smiles. [7]
