In today’s world, mobile phones have become an essential part of students' lives. While they offer convenience and access to knowledge, they also bring harm. Many students spend too much time playing games or using social media, which affects their study and health. They may stay up late, leading to poor sleep and low energy in class. Moreover, overuse of phones can cause eyesight problems. To enjoy the benefits of technology while staying healthy, students should use phones wisely and set limits on screen time. Balancing study and leisure is key to a successful future.
