Smiling is one of the best and simplest ways to spread positivity and warm feelings towards the world around us. It doesn’t only have a great impact on the people around, but on our own health, too. It has been proven by different studies that smiling fights stress and anxiety boosts the immune system and the release of endorphins in our bodies which leaves us feeling happier. It is also contagious which means that when we see someone smile, our brains’ area which controls the facial expressions activates, which results in us smiling, too. A simple smile makes us more approachable and attractive to others. It shows that we are open to socializing and that we are confident in ourselves.
