Does a Wide Smile Make for a Long Life?

It seems like each day another study comes out touting the benefits of a healthy smile and a positive outlook on life. Research has shown that that those who smile often have stable marriages, personalities, and superior interpersonal skills. However, the positive effects don’t end there. Scientific analysis done by Wayne State University in 2010 also seems to indicate that people with bigger, wider smiles may actually live longer. If that’s not a reason to take care of and show off your pearly whites as much as possible, we’re not sure what is!

The study was based on information from the Baseball Register and examined professional baseball players who began their careers prior to 1950. The photos were blown up, rated on a scale of “big smile”, “no smile”, or “partial smile”, and then were compared to deaths that happened between 2006-2009. This data was then took into account and eliminated factors relating to career length, body mass index and college attendance, which are all related to longevity. The players who passed away in this time on average lived 72.9 years for those without smiles, 75 years for those with partial smiles, and 79.9 for big smilers .

The authors of the study claim that there is some solid scientific reasoning behind the results. Positivity has been shown to be a factor in mental and physical health. It’s impossible to know whether the smiles in the photos were elicited by the photographer or spontaneous, but either way bigger smiles tend to reflect genuine happiness more than partial ones.
