The World Health Organization defines health as: health is not only the absence of physical disease, but also a good state of physical, mental and social well-being, which means that health refers to a person’s physical health, mental health, social adaptation health and moral health are sound in four aspects. It is easy to see that mental health is an important part of people’s health, so what is mental health? Most people believe that physical diseases can not only be seen and felt, and most of them can be detected by laboratory or imaging tests; but mental health is not only invisible, and can not be objectively checked out by instruments, in fact, we can see through a person’s long-term behavior patterns and thinking patterns and recent changes in their behavior thinking, thinking, emotions, will and behavior are able to see this person The development of modern psycho-psychometrics has also made the detection of mental illness a fact. Therefore, it can be said that mental health is visible, so what are the signs of mental health for our reference? 1, the basic needs of individuals are satisfied to a certain extent: American psychologist Maslow put forward his theory of hierarchy of needs in 1968, he believes that human needs can be divided into five levels, namely, physiological needs, security needs, the need for love and belonging, the need for respect and the need for self-actualization. According to Maslow, whether from the perspective of racial development or individual development, the lower the level of needs, the more powerful they are, and whether they can be satisfied is directly related to the survival of the individual, so the lower level of needs is also known as the basic needs of human beings. Only when the lower needs are satisfied, the higher needs can appear. In other words, only when people’s needs for food, air, water, sex and rest (including places to sleep and live) are guaranteed, then the needs for life and property, order, stability and freedom from fear and anxiety arise. Otherwise, if you do not have enough food to eat, clothing, schooling, jobless, living in the days of being hunted and scolded by others, I am afraid that people live a very bitter heart, not to talk about happy and healthy. However, to the other end of the spectrum, all day long, luxury clothes, cars and BMWs, beautiful women, eat a big meal every day, is happiness and happiness to the clouds? Not really, almost all happiness surveys have a conclusion: happiness and wealth relationship into an inverted U-shaped, that is, very poor people are not happy, because the basic needs of survival are not met, extremely rich people are not happy, because then the pressure to maintain the status quo is very great, fear of kidnapping, fear of personal privacy violations, many lovers between the jealousy, etc., the happiest part is the middle The happiest part is the middle part, the basic living conditions are good, and there is not much pressure and distress. Therefore, it is wise to stay in the middle state, is too much money in the charity business, so that their own happiness, others can also get a warm, but in China to do charity business suffering is not a lot. 2, maintain the relative integrity of the personality and the relative stability of the emotions: the structure of the personality composed of various psychological characteristics is relatively stable, the personality of this thing although we can not see it directly, but it tells with behavior, its influence on the behavior of people is consistent, is not limited by time and place. The stability of personality does not mean that he will not change, in fact, with the change of social living conditions and the development and maturity of a person and the accumulation of life experience, personality characteristics will also change to a greater or lesser extent. People have different emotional experiences such as happiness, anger, sadness and joy, unpleasant emotions must be released in order to seek psychological balance, otherwise unpleasant emotions are not released, the more accumulated, over time, is bound to produce psychological problems. Emotional venting should be appropriate, you can shout, you can cry, you can get drunk, you can also go for strenuous sports, but the premise is not to hurt others, otherwise the problem is not solved, and intensify the interpersonal conflicts, and will generate new worries. Another situation is: if a person in most cases meek nature, eager to help, and because of some small things and lose their temper, so repeatedly, not only their own pain, mood, others will also be far away from it. 3, and the outside environment to maintain appropriate contact and maintain a certain learning ability: an important feature of modern society is the rapid changes, if you do not read a few weeks or 1 month, do not read the newspaper, do not go online, then you do not even know the advantages and disadvantages of the deposit, the price of food, oil and salt, the rise and fall of housing prices and other information, etc., do not understand, not to mention what “floating clouds “”Phoenix man, peacock woman”” “Pan Jun thin Australia HOLD her?” ”cute” and other fresh phrases you can not understand, and will not communicate with young people. As a medical worker, the development of medicine is ever-changing, if you think that experience allows you to eat the rest of your life without learning, then you are very wrong, young doctors through the network, magazines, purchase new books and other ways to learn, perhaps a few years later exceeded you, then you will be too late to regret! But inertia once formed, even so, you do not want to change yourself. 4, maintain good interpersonal relationships: interpersonal relationships are the direct psychological relationship between people and people established in the process of interaction. In China, as long as you open your eyes, bumping into all the people, want to hide can not hide. Today’s society, want to do a thing, by themselves is often unable to do, must be done through the help of friends, so in a group, good interpersonal relations is very important, or I’m afraid that a good day can not live. Poor interpersonal relationships are often an important factor in causing illness. Many people talk about interpersonal relations is a headache, as if the profound can not learn. In fact, many things in the world can be handled very smoothly by following simple principles. Without direct contact and interaction will not produce interpersonal relationships, interpersonal relationships once established, will certainly be directly experienced by people, in order to maintain the relationship must be in regular contact. The first is the principle of mutuality, the basis of interpersonal relationships is the mutual importance and support of each other. No individual accepts another person without a reason. Mutuality is the prerequisite for liking. At times, interpersonal interactions are a social exchange process. The principle of exchange is that individuals expect interpersonal interactions to be valuable to them, that is, the gain in the process of interaction is greater than the loss, or at least equal to the loss, that is, this interaction is the result of the choice of both parties according to their own values. The third self-protection principle: for others who affirm their self-worth, individuals identify with and accept them, and counter-invest in affirmation and support; while others who deny their self-worth are distanced. In short, happy to interact with people, both stable and extensive interpersonal relationships, but also have friends; in the interaction to maintain an independent and complete personality, self-knowledge, not subservient; can objectively evaluate others, taking the strengths of others to make up for their shortcomings, generous to others, willing to help others, etc. 5, people should have self-knowledge: the so-called self-knowledge, that is, a person fully understand their various strengths and weaknesses, abilities and social status and make appropriate judgments, and have the words and behavior appropriate to it. Self-knowledge, a very important concept in psychiatry, is equivalent to self-control or introspection or disease awareness. As we all know, people with mental illness who do not have self-control or do not admit that they have mental illness, do not have the ability to correctly recognize and criticize the abnormal speech and behavior in the illness, and refuse treatment are classified as heavy psychiatric illnesses, simply put: these people do not have self-awareness (while the recovery of self-control is one of the important indicators for doctors to judge the recovery of mental illness), and conversely, they are diagnosed as light psychiatric illnesses or Psychological disorders (various neuroses and most depressions are classified as such). Thus, it is easy to see how important self-knowledge is for an individual living in modern society. Knowing oneself well is not easy to do. Even Socrates spoke of “knowing oneself” as a very important thing. However, I am afraid that we can be much more objective and truthful as long as we admit in our hearts that we all have flaws, strengths and imperfections, and we are not exempt from them. Think of it this way: I definitely have flaws, but I definitely have a lot of strengths. The key to the problem lies in whether you will be able to build on your strengths and avoid shortcomings, after the problem is not just to find fault with others, it is important to start by looking for themselves, the terrible thing is that we are used to finding the cause of their own problems infinitely narrow or ignore them, the shortcomings of others infinitely enlarge or the problem is caused by the other party, they have no conscience. Casually put any one in the world in front of us, even a beggar, we can find out where he is not as good, even if it is a little. Beggar really look open, put down, the seemingly complex life for the maximum degree of simplification, in addition to filling the stomach every day, fall of nothing, while we are busy for work, study, friends, title / position promotion, parents, children, etc., which is about 1/4 of the people still have to use some sleeping pills from time to time to sleep reason. Of course, the sign of mental health is not only this, life goals are realistic, timely use of their talents and interests, compliance with social morals and laws and regulations, and appropriate to delete some unpleasant things in the past is also very important.
