Scientists are trying to determine if health benefits can come from fake smiles as well as genuine ones.
"Smiling could be good for your health.
"Researchers are finding that wearing a smile brings certain benefits, like slowing down the heart and reducing stress. This may even happen when people aren't aware they are forming a smile, according to a recent study. The work follows research that established that the act of smiling can make you feel happier.
"Some research suggests only a full and genuine smile affects the body in positive ways. Other studies, though, indicate even a polite smile may be beneficial. Frowning also may have a health effect: Preventing people from frowning, such as with the use of Botox, can help alleviate depression, a recent study found.
"'You can influence mental health by what you do with your face, whether you smile more or frown less,' says Eric Finzi, a dermatologic surgeon and co-author of the study on frowning."
