Many see smiling simply as an involuntary response to things that bring you joy or inspire laughter. While this is certainly true, it overlooks an important point: Smiling can be a conscious, intentional choice.What does psychology have to say about smiling? Whether your smile is genuine or not, it can act on your body and mind in a variety of positive ways, offering benefits for your health, your mood, and even the moods of people around you.
