As an ordinary citizen, I think it should be able to play a significant role, especially in today's Internet age. No matter high school students or college students, most of their time and energy are devoted to the virtual network world, and there is less and less interpersonal communication in real life, which is very unfavorable for the communication and talk in the inner world. However, the interaction on social platforms is becoming more and more frequent, but they think that the sensitivity of topics and the formation of circle culture seriously restrict students' horizons. Over time, it is easy to form a narrow outlook on life and world, and even extreme behavior may occur, which is also the starting point for individuals to think that physical exercise is needed to alleviate students' depression.

As a student with relatively poor self-control, he has been in a relatively limited social circle for a long time and is prone to extreme and depressed emotions. I believe this is also the cause of suicidal thoughts. If we can find the lost sunshine and innocence in the process of physical exercise,
