For more than a dozen years, scientists from all over the world have been debating whether smiling makes people happier. Just a few years ago, 17 groups of scientists could not confirm the results of previous studies, according to which a smile in itself can raise a person's mood.

It is not only about emotional feelings, but also about simple physical action. Another attempt to understand all the nuances of this phenomenon is based on 138 studies since the 1970s, including data analysis of more than 10 people.

Scientists have proven the influence of facial expression on the emotions experienced by a person. Namely: a smile can affect our mood in a positive way, and our own angry look, on the contrary, makes us feel angrier.

According to the author of the article, Nicholas Coles, it is impossible to state with certainty that happiness consists in a permanent smile on the face. However, scientists managed to obtain valuable information about how our brain and body interact with each other, forming the perception of experienced emotions.
