Why do girls love to laugh

In any corner of society, we can see girls' smiles. Sometimes I laugh, sometimes I smile with my mouth closed, sometimes I laugh nonstop, and even I burst into tears. It is strange that they often laugh inexplicably or meaningless. After careful analysis, girls' laughter may have the following meanings: First, it indicates intimacy or intimacy. For example, laughter when meeting friends and mothers; The second is to show respect. For example, I saw a teacher on campus in the morning; Show shyness again. For example, being praised by others, laughing when meeting strangers or appearing in public; The last point is the most puzzling. Girls also laugh when expressing confusion, melancholy, covering up love or some kind of psychology. We have to admit that girls' laughter is sometimes complicated and intriguing. Why do girls laugh so much? Girls' love to laugh is not morbid, but a manifestation of normal understanding, optimism, strong will, hard work, coordinated behavior and correct response. In short, it is the embodiment of healthy psychology. Girls love to laugh because of complicated physiological reasons. Laughter is the external expression of feelings. The occurrence of human emotions and feelings is directly related to the hypothalamic reticular structure and the limbic system of the brain. Hypothalamus is the subcortical center of autonomic nerve. 1954, Oder and Milner pioneered the buried electrode method and conducted self-stimulation experiments. It is found that there are "pleasure center" and "pain center" in hypothalamus. When the sensory information from emotional stimulation reaches the hypothalamus, on the one hand, it is uploaded to the cerebral cortex to form emotional experience; On the other hand, it is transmitted to muscles, glands and other "expression organs" to produce emotional reactions. Because of the existence of female hormones, the balance between pleasure center and pain center is different from that of men, which leads to different emotional experiences and reactions of women. Another main reason why girls love to laugh is the complicated social factors. In the long history, there have been social and psychological differences between men and women, and there have been personality differences. Women's personality is mainly emotional, passive, closed, integrated, obedient, attached, inferior and self-enclosed, so women's response to external things is not as rational, active, open, antagonistic, dominant, independent, superior and self-prominent as men's. Therefore, laughter has become one of the important ways for women to cope with complex social factors (another way is crying). Because the meaning of laughter is ambiguous and can be understood in many ways. Of course, we are talking about the general law of personality differences, and there are also "feminine" and "masculine" in life. Finally, girls' smiles are beautiful, but when it is necessary to express their views clearly in language, it is best not to use smiles instead to avoid misunderstanding.
