    Smiling really can make people feel happier, according to a new study. American psychologists (心理学家) looked at nearly 50 years of data testing whether facial expressions can lead people to feel the emotions related to those expressions. They found smiling made people feel happier; frowning (皱眉) made them feel angrier or sadder.

However, the effects are not so strong, and the researchers warn this should hardly be held up as a way to offset weak mental health conditions like depression. Lead researcher Nicholas Coles said: “Ordinary wisdom tells us that we can feel a little happier if we simply smile. Or that we can get ourselves in a more serious mood if we frown. But psychologists have actually disagreed about this idea for over 100 years.”

The research team says the disagreements became more pronounced in 2016, when 17 teams of researchers failed to copy a well-known experiment showing that the physical act of smiling can make people feel happier. Coles said: “Some studies have not found evidence that facial expressions can influence emotional feelings. But we can’t focus on the results of any one study. Psychologists have been testing this idea since the early 1970s, so we wanted to look at all the evidence.”

Using a data technique called meta-analysis (荟萃分析), the team collected data from 138 studies testing more than 11, 000 people from all around the world. The results of the meta-analysis suggest that facial expressions have a small influence on feelings.

Coles added: “We don’t think that people can smile their way to happiness. But these findings are exciting because they provide evidence about how the mind and the body affect each other to shape our experience of emotion. We still have a lot to learn about these effects, but this meta-analysis put us a little closer to understanding how emotions work.”
