The Influence of Internet Dependence on Mental Health and People

First, it affects interpersonal communication. Studies have pointed out that Internet addiction is related to dopaminergic, which is a substance directly related to the joy and excitement in the human brain. Teenagers get special experience directly through the internet and feel happy and relieved, which makes them attached to the internet and gradually divorced from the real world, and then may directly replace the real interpersonal relationship with the virtual interpersonal relationship on the internet. Norman, a scholar at Stanford University, believes that the Internet will create a world full of lonely people. In other words, the trend in onlineness will become more and more obvious. Teenagers at the peak of social development should take part in more social activities, have more emotional exchanges with people and truly experience life. However, the extensive use of the Internet directly reduces the communication time with parents, classmates and friends, and forms the indifference to the actual emotional communication. Although the new network communication mode also has its advantages, it weakens the normal interpersonal communication in the real world, hinders the development of teenagers' socialization, and causes teenagers to be more uncomfortable in their daily life, which in turn depends more on the network, forming a vicious circle.

Second, it affects personality development. The shell of personality is the individual's words and deeds, that is, the external performance, while the core of personality is the individual's internal stability. Personality is formed under the interaction of heredity, environment and maturity, and the acquired environment has a great influence on personality. In the real world, due to many legal and moral constraints, people will basically pay attention to their words and deeds. In the virtual network world, there are not too many constraints and pressures, and people's emotions and thoughts that cannot be expressed in the real world can be released. The important task of adolescence is to develop the self-identity of personality. Teenagers have limited cognitive level and poor coordination ability, and sometimes it is difficult to smoothly change roles between the virtual world and the real world. The role of virtual network is often divorced from reality, and it is easy to split personality, which leads to confusion of self-identity. This long-term role confusion will change the personality of teenagers in the real society, form the network personality characteristics of depression, closure, emotion and inferiority, and even eventually lead to personality variation such as personality split, hysterical personality and antisocial personality.

The third is to cause moral problems. It is precisely because the virtual network world lacks many legal and moral constraints of the real world that virtual identities can be used, and teenagers have relaxed their shackles on the internet, their sense of responsibility has weakened, and their sense of freedom has flooded. Teenagers still lack certain discrimination and self-control, and all kinds of negative information on the internet will have a very negative impact on them. Long-term exposure to some bad information will make teenagers lose themselves and lose certain moral norms. In the overwhelming network information, it is difficult for them to form correct values and outlook on life. Attacks, violence and other elements in many games may make some teenagers think that those behaviors are reasonable in the real world, which may lead to illegal and criminal acts such as violence. In addition, the uniqueness of teenagers' physical and mental development makes them pay attention to sexual problems, and there are a lot of unhealthy and even pornographic content on the Internet. Under the influence of these contents, teenagers' sexual concepts are easily misled, resulting in sexual crimes. Teenagers are not economically independent. In order to meet their internet addiction needs, there will be many illegal acts such as theft and robbery.
