Besides heart disease, mental illness is the biggest disease in Europe. Up to 27% of Europeans have had psychological problems at some point in their lives. According to EU statistics, the number of people who commit suicide due to mental illness in EU countries reaches 58,000 every year, which is more than the number of people who die in car accidents and murders. Psychological obstacle is one of the three major reasons that lead to absenteeism, early retirement and application for work-related injury and disability allowance for employees in EU countries. According to conservative statistics, the losses caused by mental illness to European countries are equivalent to 3%-4% of their GDP. In fact, Europe, especially Western Europe and Northern Europe, has a relatively high standard of living and a relatively sound social health and welfare system. An expert on social issues pointed out the root of the problem: the mental health of a society is related to the material living conditions, the degree of harmony of a society as a whole, and the degree of concern and care for individuals and humanity from the system and real life. Sometimes, the improvement of material living conditions provides a "hotbed" for the emergence of more mental diseases. Because when the basic conditions of material life are no longer the primary goal of a person's struggle, he will have higher spiritual needs and more time to pursue spiritual needs. Therefore, even if a society has a very high material standard of living, it is prone to problems if it does not do enough spiritually.
In today's globalization, China can't be immune to it, and people's psychological problems emerge one after another. A survey shows that the incidence of mental illness in China has surpassed that of cardiovascular disease, ranking first. About 30 million teenagers in China have different degrees of psychological problems. During their stay in Spring Festival travel rush this year, some local railway bureaus organized police officers on trains to receive psychological training as "psychological stress releasers". Because there will be "car epilepsy" during the peak passenger flow every year, these people will suddenly jump out of the car, cut people, cry and throw money because of excessive mental stress in some aspects. Song Yumei, a famous psychological counselor, told reporters that people will always encounter things that make them unhappy, and negative emotions will arise. If negative emotions increase too fast and are not released in time, once they are beyond people's tolerance, psychological problems will develop in a vicious direction and people will suffer from different psychological diseases. Out-of-control emotions are introverted, and in severe cases, they will commit suicide. Out-of-control emotions are extroverted, and sometimes they are destructive or even antisocial.
From a macro point of view, some sociologists believe that modern society is an information-based and global society, and the information explosion will bring a large number of news of social imbalance and social injustice to the public quickly, resulting in psychological imbalance of many people. In addition, changes in lifestyle such as residence have led to an increase in people's strangeness and a decrease in their sense of belonging. Coupled with the intensification of social competition, the acceleration of the pace of life and the impact of foreign culture on the original values and ways of thinking, people are experiencing an unprecedented impact. In this environment, it is not difficult to understand that psychological problems have become "global diseases".
