What is a smile?
Laughter is the expression of human emotion. Feeling good, happy, joy and the emotion that comes to our mind after any achievement, it is revealed through laughter. But we are not consciously laughing like ‘now you have to smile, everyone smile’. Laughter is the expression of spontaneous emotion. And consciously ‘have to smile’, so to put a sweet smile on the corner of the lips with the annoyance of the state in mind is an artificial smile.

Emotions stimulate the ventromedial prefrontal cortex of the brain, causing the release of a chemical called endorphins, so we laugh. When interpreted differently, emotions cause laughter in the movement of our muscles, then endorphins are released in the brain. It's a lot like 'before the egg or before the chicken'. Activation of the limbic system of the brain and the part called amygdala also plays a role in creating laughter. According to Sigmund Freud, laughter relieves anxiety, anger and sadness; So laughter is important.

Laughter is a means of communication between us. Because, mentally healthy people do not usually laugh alone, they laugh in front of others. Laughter is contagious, that is, when a person starts laughing in a chat, it spreads to everyone. During laughter, the muscles of our face, neck, neck, chest and hands move, and breathing changes. A child who is developing normally learns to smile before learning to speak. Normally, he can smile spontaneously within three to four months of birth, but if he cannot smile spontaneously within six months of birth, it should be assumed that his development is slowing down. Children smile about 100 times a day and adults smile about 10 times a day. There is a lot of research on laughter. Without going into theoretical analysis, we generally see several types of laughter — laughter (loud laughter), smirk (silent laughter), wooden laughter (laughter with difficulty), crooked laughter (sarcastic laughter), suppressed laughter (as much as desired) Don't smile in your mind), Cruel smile (revenge smile), Fake smile (fake, fake smile) etc.
