Being addicted to the Internet would have a serious impact on one's physical and mental health and social life. The virtual world and excitement in the online world made it easy for people to lose themselves and neglect interpersonal relationships and practical needs in the real world. Sitting in front of the computer for a long time may cause eye fatigue, cervical vertebra disease, lumbar vertebra disease, and other problems. Overuse of the internet can also affect people's social skills, making them lonely and autistic, and even losing the opportunity to meet and communicate with friends. Being addicted to the Internet would also cause one's creativity and thinking ability to be suppressed, affecting one's intellectual development. Therefore, we should use the Internet appropriately and cherish our physical and mental health and social life.
