Women have menstruation (commonly known as "menstrual period"), which is arranged by God. But God has a good sense of humor and is always fair. Men also have a few days a month, uncharacteristically depressed ... the cycle is about 28 days. Like all women, men also have "periods"! You may scoff at this, but it's true. Be punctual like a woman. Women's psychological fluctuations are mostly related to the physiological cycle. Although men do not have an obvious physiological cycle like women's menstrual period, they also have a biological cycle of about one month. According to some foreign studies, people's physical strength, intelligence and mood are all controlled by the biological rhythm in the body. The emotional rhythm cycle of men, that is, the "psychological cycle", is about 28 days. "Two or three days after the 28th is an inconvenient day for men. Physical discomfort such as laziness, loss of appetite, dizziness, insomnia, etc. At the same time, it will be accompanied by emotional fluctuations such as depression, irritability, indifference and decreased sexual interest. " This periodic low mood is common among men. Some foreign medical experts call it the "low tide" phenomenon of men. This is actually a change of biological rhythm, which is the result of the change of hormone level in men. 1. Emotional cycle is manifested in both men and women, but the performance of men is different from that of women. Men are controlled by anxiety during this period, which will seriously affect their study and interpersonal communication. 2. There will be some pathological manifestations in the low tide of men's physiological cycle, which will affect men's creativity, sensitivity and understanding of things, as well as some emotional, mental and psychological functions. In the period of "emotional climax", people often show great energy and laughter; During the period of "depression", people will feel bored and grumpy, and even have violent and suicidal tendencies in severe cases. 3. All living things have biological rhythms. Human growth, development, physical strength, intelligence, heartbeat, breathing, digestion, defecation, sleep and even human emotions are all controlled by the biological rhythm in the body. It's just that some people have obvious rhythms, while others don't. This is actually the result of his own biological cycle rotation. That is, we are going to talk about biological rhythm. Most of them happen during the full moon. Every man's "official holiday" cycle is different, but some data show that the "attack period" of men's "official holiday" is the days of the full moon. For example, American studies have found that the crime rate, suicide rate, domestic violence and alcoholism are above average during the full moon. No wonder in Latin, the original meaning of the word "mental disorder" is "influenced by the moon". How do men check their periods? It is a physiological phenomenon that many people have seen but never paid attention to that two ways to deal with men's "menstrual period" skillfully and learn to relieve the pressure of men's "psychological period". In addition, psychology believes that in addition to physiological reasons, the pressure of life and the troubles of work are also the causes of periodic depression: when the work pressure is too great and can not be alleviated, it is like a bomb being detonated in the body, causing periodic imbalance of hormones and neurotransmitters in the brain, thus causing men to have periodic psychological tension, depression, loss and emotional ups and downs. Experts say that men have bad emotions such as impatience and impulsiveness during the psychological period, which is easy to induce digestive system diseases such as digestive tract ulcer, colitis, constipation or diarrhea. Therefore, men should have enough knowledge of their own bodies and conduct appropriate psychological mediation. Find some healthy recreational activities to relieve stress. Experts who participate in many sports and group activities say that although there is no unified conclusion about men's psychological cycle, we can see that when men have psychological fluctuations, they often hide their true emotions, or show them in unhealthy ways such as drinking, gambling and participating in stimulating activities. But experts obviously disapprove of this practice. When men have psychological fluctuations, they can vent through exercise. After moderate exercise, the body excretes not only sweat, but also depression. When you encounter problems that you can't solve, you can ask for help from people around you, or ask for help, or relieve your psychological fluctuations by talking; You can also choose to participate in some group activities, watch a meaningful movie, visit an exhibition and so on. And replace those bad vent channels with these methods. Experts suggest that in the critical period and low tide, men should pay attention to the combination of work and rest, actively adjust their physical functions and emotions, reduce their workload and decompress themselves. Because men's "menstrual period" is not as obvious as women's menstrual period, it is not easy to locate clearly and easy to be ignored.

During this "holiday", you will alienate people you know and even run away from home alone. After three months' records, if more than two of the above items 10 appear regularly, the time period of "official holidays" will be found. In men's "those days", most men, even if their hearts are rough, seem confident and poised. In fact, they are secretly fighting with themselves and fighting hard ... as a result, they have inexplicably done stupid things that they can't explain. Men should not drive on legal holidays. If men also have their period, there is no doubt that a new type of male sanitary towel will occupy the market in an all-round way! All sanitary towel manufacturers will take 50% profit points for nothing, which will lead to a blowout in this industry. The shape of this sanitary towel needs further study. 2. Male sports stars have added a new advertising revenue, such as Liu Xiang. His advertising slogan may be: there are always a few days every month, which makes it difficult for me to cross. With XX brand sanitary napkins, I can cross myself! 3. When the wife asks in bed with desire, the man can say shyly, "Wife, not today! My uncle is coming ... "4. When the team takes part in important games, it needs to adjust the time difference and the holidays of the male players. The football report will appear: Ladies and gentlemen, Manchester United is not full at present. In addition to several main injuries, striker Rooney also temporarily withdrew from the game because of dysmenorrhea. A friend asked him, "Was your girlfriend a virgin when she first slept with you?" The man replied shyly, "I don't know, when we had our first holiday …" 6. The husband and wife came to spend the holidays together. They couldn't touch cold water or do housework, so they ate instant noodles for seven days. 7. A man went to see a doctor with great anxiety and said, "Doctor, I haven't had my period for two months! What do you think is going on? " After careful examination, the doctor said, "Your prostate is blocked ..." 8. A little boy came home crying with blood all over his lower body. His mother kindly told him what to pay attention to when he came to menstruation for the first time, and encouraged him to say that he was already a real man! The theory of three rhythms of human biological clock refers to the fluctuation of a person on his own "horizontal line". When the three rhythms of intelligence, emotion and physical strength are in a critical period or at a low tide, people do feel mental decline, emotional instability and physical fatigue. Biological rhythm treats everyone equally, but it has different effects on different people. For example, for a student, if he happens to have a big exam, he may be at a low ebb and affect his level. For a doctor, if he happens to be on the operating table that day, not necessarily, but the probability of his abnormal performance is relatively high. Doctors advise men not to drive during "official holidays". According to "China Traffic News", "Ningbo Freight Station of Zhejiang Automobile Transportation Company implements the system of compulsory rest for drivers in double or triple critical periods. For drivers in a single critical period, note on the waybill: "Today is your critical period, please pay attention to safe driving. "Some drivers said," When you think you are in a critical period, driving will be much more stable. "After taking this measure, the accident rate of this team has dropped greatly.
