(1) Affecting academic development. Once college students are confined to online dating, they are often reluctant to think about "books". Some college students are crazy all day, daydreaming, immersed in the sweet words of loving each other. When online dating has gradually become the only pursuit of life, it is not surprising that the spirit is empty and the goal of life is lost. These daydreams of different degrees often seriously interfere with the normal study of college students, leading them to neglect their studies, drop their grades, even repeat grades or even drop out of school.

(2) affecting health. Online dating takes up a lot of precious time of college students, which is not good for health. The distance effect and mystery of the network can easily make college students addicted to online dating. Once they are addicted, they will be addicted to the network and it is difficult to break free. Surfing the Internet for a long time is often due to the high excitement and tension of the brain nerves for a long time, which leads to an abnormal increase in adrenaline level, excessive excitement of sympathetic nerves, high blood pressure and neurological dysfunction, which easily leads to decreased vision, insomnia, headache and neurasthenia, and affects the health of college students.

(3) bring mood swings and mental illness. College students who surf the Internet for a long time show positive emotional states such as excitement, concentration and responsiveness. However, when we leave the network and return to real life, we often feel emotional and restless, showing our dependence on the network and indispensable needs. Online dating has the characteristics of great virtuality and anonymity, which makes it difficult for college students to determine each other's identity when online dating. There is a gap between virtual identity and reality, and the communication means and methods in online dating are also different from those in reality. When college students really return to reality, they will not adapt and become withdrawn, inferior, closed and unsociable, which will cause some psychological diseases for a long time.
