As a fan of online literature, I think this phenomenon is abnormal. Staying up late to play with your phone in the wee hours of the morning can have a negative impact on your physical and mental health and may even lead to problems such as insomnia and depression. College students should maintain good habits to ensure adequate sleep in order to learn and grow better. At the same time, we should also pay attention to the impact of mobile phones on health. Try to avoid using mobile phones for a long time and do more beneficial activities to maintain physical and mental health.
