5. Reduce Pain

Our bodies release natural painkillers called endorphins when we laugh. These endorphins are moderately pain-relieving. Sarah Pressman, a UCI professor in psychological science, conducted a study that looked at the effects of different emotions on pain and discomfort.

The pain associated with the injection of a needle was no greater than that experienced when you get a flu shot. The injection felt half as painful for those who smiled during it than those who did not smile. What does this mean? It is possible that there could be a correlation between your facial expression and pain. Next time you go in for a shot, smile and keep your face open. This might help.

6. Boosts Mood

We smile when we're happy, and frown when we're sad. These actions directly correlate with the emotion. According to some studies, smiling can make your brain believe you are happy. According to psychologists from the University of Cardiff, people who have had Botox injections that made it difficult for them to smile reported feeling happier than those who can smile normally.

American Psychological Association published another study that found smiling, even if forced, can produce more positive emotions. Studies have also shown that frowning can cause you to feel unhappy. You may feel happier if you smile next time you feel down. If you are suffering from anxiety or depression, or if you have persistent symptoms, it is important to consult a healthcare provider.

Another study showed that smiling people are perceived as more likable and therefore can form better relationships. A second study, published in Journal of Personality and Social Psychology, found that smiling and positive expressions predict better outcomes in life. This includes happier marriages and greater satisfaction.
