How to Improve students' Mental Health Have you ever heard college students moan in depression? Do you know anyone with learning pressures? The sad fact is, mental health is becoming an increasingly troublesome issue for undergraduates. But solving the problem calls for collaborative between universities and students themselves. On the part of universities, courses of mental health should be added to the curriculum. Besides, the counseling center staff and faculty alike are expected to expand and improve mental health services on campus. On the students' part, they should try to face the reality and figure out the causes of depression so that they can better understand it. They should also learn how to identify unhealthy behavior or thoughts and make changes accordingly. Besides, students should communicate more with friends, teachers and parents, find better ways to cope with and solve problems, and set realistic goals for their life. To conclude, universities should pay more attention to students' mental health, and put more effort into developing mental health counseling system on campus, whereas students should try to stay positive and optimistic, and fine ways to solve their own problems.
