SAN ANTONIO — If you're having a bad day or can't seem to shake a bad mood, try smiling, even if it's a fake one.
According to a paper for Psychological Bulletin, smiling can make people feel happier.
Researchers at Texas A&M University and the University of Tennessee studied nearly 50 years of data to determine whether making a facial expression such as smiling or scowling could lead people to feel the emotions related with those expressions, happiness or anger, respectively.
While researcher Nicolas Coles acknowledges that they "don't think that people can 'smile their way to happiness'" through the use of meta-analysis, they did find that posing facial expressions has a small impact on our feelings.
The team combined data from 138 studies testing over 11,000 participants from all around the world.
