Laughter is a kind of survival ability of human beings. Just like doctors check all parts of the body, laughter has become a correct and effective indicator to measure health. "People are born to laugh, but few people know that laughter is also a good exercise. Every time you laugh, there are about 80 muscles involved in the exercise from the face to the abdomen. If you laugh 100 times, the exercise of heart blood circulation and lung function is equivalent to rowing 10 minutes. Unfortunately, when people reach adulthood, they only laugh 15 times a day on average, which is much less than 400 times a day when they were children. This is at least a regrettable loss of health. As long as you laugh, the muscles of your mouth and cheekbones will laugh with you, pulling your mouth and eyes up. This kind of facial massage can prevent facial lines from falling. Laughter, isn't it just a beauty exercise to keep young? Laughter can cure muscle strain. Because the muscles of neck, back and waist are in a fixed position for a long time, excessive tension and contraction can easily cause headache and backache. Laughter can make muscles in some parts contract, muscles in other parts relax and relax, so that tired muscles can relax during exercise. This is really a good way to relieve spasmodic pain. People with this kind of occupational muscle strain will undoubtedly benefit a lot from this special exercise as long as they laugh often. Laughter helps breathing. When laughing, with the movement of respiratory muscles, the chest and bronchi expand one after another, which not only enhances the ventilation and blood oxygen saturation, but also helps to supply oxygen to the heart, and also has a certain therapeutic effect on patients with asthma and emphysema. As an effective deep breathing exercise, laughter has been recognized by more and more people. The ups and downs of abdominal muscles accompanied by laughter is an excellent abdominal muscle exercise. The intense contraction and vibration of abdominal muscles during laughter not only helps to squeeze blood into thoracic vein and improve blood supply to myocardium, but also is an excellent massage for stomach, intestine, liver, spleen, pancreas and other organs. This is why people with digestive disorders are improved and treated in laughter exercise. A knowing smile can relieve pain. People's laughter comes from the right frontal lobe, which is in charge of emotions. Every time you laugh, you can stimulate the brain to secrete a hormone that can make people happy-endorphins. It can make people feel relaxed and happy, its analgesic effect is 40 times that of morphine, and it is very beneficial to relieve depression and various pains. Laughter can't help but be cultivated. However, although laughter doesn't need to be bought or borrowed, it needs "input"-you should always associate with people who like to laugh. Because I often get along with people who love to laugh, I am immediately infected when I am in it. Pay attention to collecting funny jokes, humor and other materials, and you can't help laughing when you taste them. As long as you have time, try to appreciate comedy, cross talk and other art that makes people laugh, so that you can laugh more. Of course, if you often ponder and practice the art of laughing, so that your laughter will come at once, you still have to work hard. Don't ignore the smirk. " What's fake is real. A psychologist said, "As long as you can take a lie as truth, a sincere smile will follow, which can produce almost the same effect as a real smile. "Laughter can improve health. Raymond Moody, a famous American psychiatrist, said in his book "Smile-the Power to Give Health": "I found that laughter is a kind of survival ability of human beings, just like a doctor checking all parts of the body, laughter has become a correct and effective indicator to measure physical health. "So many organs can benefit from the shock of laughter. As an indicator of exercise and health, laughter should be fully valued and utilized. = = = = = = = = = = = = = = = = = = = = [Edit this paragraph] Psychologists now find that laughter is one of the oldest ways for human beings to communicate with others. Human laughter is to unite with others or laugh at others, or tease others with laughter. Each of us mastered this skill long before we learned to speak. Not just for fun. Laughter is an expression. So far, scientific research has always associated laughter with humor. But scientists have recently discovered that another aspect of laughter is more important. It has nothing to do with humor. We laugh, but we always underestimate its function. Through laughter, people send messages. Although many people will hear laughter, only certain recipients can understand the information in laughter. This kind of information is like encryption, because it is directly aimed at the receiver and does not require his conscious understanding. " Psychologist Ioanna said, "This is a big joke. 6? 1 Holovsky said. She played an experimental video: a woman began to laugh. When she starts laughing, it's like coughing. Then she raised her tone rhythmically until she approached the high note of the bird. In 20 milliseconds, she raised her pitch to an astonishing 1000 Hz-which is10 times higher than her normal voice frequency. Anna? 6? 1 Ba Holovsky said: "This is a kind of smile that can make people feel comfortable." She pointed to the TV screen again, and the next part of the experiment was aimed at men: "'She is interested in me', and this man will' dream' when he hears a woman smile like this. "Human conversation is full of laughter. Anna? 6? Holovsky is a psychologist at Vanderbilt University in Nashville, USA. She is one of six scientists who study human laughter all over the world. From snoring, wheezing, coughing or snoring to mixed sounds, like birds jumping up and down, they are all laughter. It is doomed to be futile for a person who gives out some kind of laughter to let him repeat these sounds on purpose. Because his vocal organs are not ready to be funny like that. In order to investigate the structure of laughter, psychologist Ba Holovsky listened to 109 samples of laughter. She found that the continuous rapid laughter lasted from 0.04 seconds to almost 6 seconds. Men and women are the same. Laughter is a social tool. When a person is alone, his throat rarely trembles. Giggling, suicidal laughter and harsh laughter only happen when people are with other people. People who laugh often interrupt the conversation and wait until the laughter is over before continuing the conversation. And the people who laugh rarely notice it themselves. " Obviously, people are looking for opportunities to laugh. "Holovsky said. Women are better at laughing than men. When men give out deep laughter, the frequency reaches 43 Hz, while women's sharp laughter can reach 2083 Hz, even breaking glass. In addition, women's laughter is more beautiful, while men can only give out gasping laughter most of the time. The reason for this difference has not been studied at present. It may be because women have developed a larger and richer sound system. Holovsky did another experiment: she sat men, women and people of different sexes together. Everyone who takes part in the experiment must draw a sketch for others with a pencil. She found that although men and women always laugh as much in three situations, when men are together, they laugh more. When women are with men, they laugh more. When a woman talks to a strange man, if she just laughs, it means she is not interested. The more times a woman laughs, the more interested she is in this man. Her interest is strongest when her laughter is in sync with men's words. Why do women master the art of laughter better than men? Holovsky's experiment shows that this is because women need to lead the process of "finding a partner" more than men. In contrast, men are not so picky as women, so their communication skills, including laughing skills, are still in a relatively rough stage. Laughter is not only a manifestation of personal comfort or happiness, but also can arouse some emotions when facing others. It seems that women can ask men through their laughter, and they are willing to meet again next time. In this way, women can accept a man skillfully, or simply refuse without telling their intentions. But in Holovsky's view, women's laughter is not only used to conquer the opposite sex. It can also help women get rid of men's potentially aggressive plans. In this case, the monotonous "ha ha ha" laughter achieved the purpose of defense, and at the same time did not embarrass men. Different smiles are related to status. When men with good relationships are together, laughing at each other with grunts and coughs can keep the conversation between them in a positive direction. Holovsky believes that hearty laughter can bring a good atmosphere. Perhaps the formation of this "laughing alliance" between men can prevent the feeling of competition and attack. In all aspects of our lives, laughter will have an impact on others. Laughter makes the "victim" look like a fool and turns himself into an aggressor. If people in a group laugh at a person, it is equivalent to excluding him from the group. Although the boss of employees is often a boring person, they still smile modestly-all in order to get the boss's favor. On the other hand, bosses use a different smile to make their subordinates feel superior. If they don't simply laugh "haha" but laugh briskly while talking, then they will lose the respect of their subordinates. Know how to laugh. You should know that when a baby is young, he will giggle at his parents and remind them to think of him often. Before he was four months old and learned to say the first sentence, the baby's throat was already smiling. Even deaf or blind babies. Even thousands of years before humans learned to speak, our ancestors communicated with each other with laughter. So can individual fragments in a series of laughter convey different meanings like words? If so, maybe the person who laughs will say, "You are really possessed!" "That's great! Boss! " Holovsky shook his head and said, "I'm quite sure that laughter itself doesn't make any sense." Laughter, as a complex signal code, involves the heart of the person who laughs and causes others to feel significantly. Cracking the code of this kind of laughter may help us to understand ourselves again. Laughter seems to be a way to eliminate psychological conflicts. As we all know, crying and laughing are both reflections of strong emotions. The crying and laughing of children and adults are essentially to meet psychological and physical needs. Laugh when you are satisfied, and cry when you are not satisfied. But the content is quite different. Children's laughter is simply psychological satisfaction, and the differences between adults are brought about by the great changes in emotional structure. The function of laughter: 1. Express psychological satisfaction. 2. vent psychological conflicts. Happiness and pain are opposite psychological states. Happiness comes from the generation and resolution of psychological conflicts, and pain comes from the psychological gap. The first function is socializing, which is used for communication. It was introduced more before. The second role is the individual, which is mainly introspective and requires high intelligence. Why are humorous jokes funny? It is because they have created an environment and created various channels of interpretation. Simple and direct reasoning channels and complex reasoning channels get the opposite results, and the intellectual needs of the two channels are different, forming an intellectual gap. The greater the difference in complexity, the greater the excitement and the uncontrollable laughter. This has much to do with people's intelligence, so people with different intelligence have different feelings and reactions to jokes. Children can't understand many jokes, and everyone can understand some simple jokes, but they need other jokes with higher IQ to understand them. Different people will have different feelings when watching the same joke. For people with high IQ, the intelligence gap between simple path and complex path is greater. Children's jokes are funny, and adults may not feel anything after reading them, because the intelligence gap of such jokes is too small. Children can't understand jokes that adults can understand because they can't find another complicated reasoning channel. People with different intelligence have different requirements for this gap. The process of jokes coming into effect is the process of getting through another complicated channel, and this process also varies from person to person.
