Excessive use of the Internet makes teenagers have a strong dependence on the Internet. In particular, the adventure and excitement of online games, the convenience of making friends online, and the * in some unhealthy content in the network will make teenagers form "internet addiction" slowly, thus losing interest in their own life and study, and prone to problems such as lack of perseverance, decline in self-control ability and neglect of their studies.
Second, the formation of "virtual personality" and the deterioration of physical quality.
The characteristics of network personality are: "loneliness, nervousness, fear, indifference and non-socialization". Attachment to the virtual world and man-machine communication between real people and computers can easily alienate people's personality from the real society, and sometimes teenagers are in a vigorous period of growth and development because of incomprehensible behaviors. Sitting in front of the computer for a long time is easy to hurt the spine, and the radiation of the computer will also endanger the health of teenagers.
Third, poor trust and poor interpersonal relationship.
In this virtual world, everyone communicates with a false virtual identity. Many times, everyone can boldly express their true thoughts or say what they want to say without scruple. But under the false identity of the network, this kind of interpersonal relationship is rarely true, full of distrust and unclear interpersonal relationship. Especially for "introverted" teenagers, although the network provides a space for everyone to show themselves, it also makes them more introverted and closed.
Fourth, distorted values and poor moral values.
The Internet has brought rich knowledge, information, spiritual challenges and pleasure to teenagers, but it has also brought a lot of "junk" information. Teenagers are the forming period of outlook on life and values, with strong curiosity and weak self-control, and are easily influenced by alienation. Especially in western developed countries, the propaganda and cultural ideas can easily make teenagers' outlook on life and values tilt and blur. In the network virtual world, interpersonal relationships are exempt from responsibility and punishment, leading to self-centered habits, especially cyber violence, fraud and other behaviors, which make the moral quality of teenagers obsessed with the network decline and their moral concepts fade.
Fifth, the network causes juvenile delinquency.
The Internet has aroused teenagers' anxiety about crime safety. Teenagers' immature physical and mental development, poor ability to distinguish right from wrong and weak sense of self-protection may weaken their moral awareness and reduce their sense of social responsibility. The hidden disadvantages and non-binding nature of network communication make it easy for teenagers to do some unconventional things and even embark on the road of crime.
