Smiling is a facial expression in which one's mouth turns upward, usually indicating pleasure, amusement, happiness, or friendliness. It involves the contraction of the zygomatic major muscles in the cheeks and the orbicularis oculi muscles around the eyes. Smiling is a universal human gesture that can communicate a wide range of emotions and social cues, such as showing approval, indicating agreement, or conveying affection. Smiling can also have a positive effect on one's own mood and can lead to improved social interactions and relationships.
