Good interpersonal communication is a necessary condition for college students' mental health.

Interpersonal communication is the guarantee for the healthy development of college students' body and mind. Everyone who lives in society will inevitably have such a relationship with others, so it is inevitable to associate with others. It is found that people who are willing to communicate with others and pay attention to cultivating good interpersonal relationships are mostly healthy and have a long life and good psychological quality. When getting along with people, there are always more positive attitudes than negative attitudes, and they have strong adaptability and sufficient sense of security in social life. And those who have bad interpersonal relationships are always out of place with the people around them and often have interpersonal conflicts. It can be seen that interpersonal communication is an important guarantee for the healthy growth of college students' body and mind.

2. Interpersonal communication is the only way for college students to socialize. Socialization refers to the process that individuals learn knowledge, skills and norms from society and others, obtain social life qualifications, and become social people from natural persons. The socialization of college students must be carried out and realized in social communication. The nature and ability of a person's communication directly affect the degree and level of his own socialization, which is the basic way to promote personal self-improvement. A good interpersonal environment is conducive to the development and optimization of personality. Living in friendly and harmonious interpersonal relationships for a long time, college students will form optimistic, cheerful and proactive personality characteristics and be able to quickly integrate into society.

3. Interpersonal communication is also the need for college students to adapt to the development of modern society. With the development of modern society, the social division of labor is getting finer and finer, so the interdependence between people is getting closer and closer, which requires people to be good at integrating the strength of others to achieve their own goals. Some human resources experts found that 95% of the employees who were dismissed were due to poor interpersonal relationships, and only 5% were due to low technical ability. The famous Hawthorne experiment also shows that the most important factor affecting production efficiency is not the treatment and working conditions, but the interpersonal relationship at work. It can be seen that good interpersonal relationship and high-quality interpersonal communication are the keys for college students to adapt to social development.
