With the changes of the times, the role of college students is no longer simply to seek students, but to undertake the important mission of promoting social progress as the backbone of society. However, in reality, the mental health problems of college students have gradually become prominent and have become the focus of social attention. They are at a critical stage in their lives and are facing unprecedented pressures and challenges. Study, employment, interpersonal relationships and other problems are like intertwined ropes, tightly binding them and making them carry a heavy psychological burden.
Therefore, how to correctly guide college students to understand themselves, regulate their emotions, and establish a healthy lifestyle has become an urgent problem to be solved. First of all, college students should establish a correct sense of self and clearly understand their own strengths and weaknesses. When making a life plan, they should fully consider their actual situation and avoid the frustration of unrealistic goals. At the same time, by participating in psychological counseling activities, they can understand themselves more deeply, enhance their self-confidence, and cultivate a positive attitude. In daily life, a healthy lifestyle plays a fundamental role in the mental health of college students. Getting enough sleep, eating a sensible diet and exercising moderately are all important factors in maintaining physical and mental health. In addition, college students should also cultivate a variety of interests and hobbies to make their extracurricular life full of fun and vitality, so as to relieve the pressure of studying. 
Harmony in interpersonal relationships is another key factor in the mental health of college students. Respect, good listening, and tolerance and understanding are the foundations of good relationships. At the same time, college students should take the initiative to communicate with their classmates, teachers and family members to seek support and help. In this way, they are no longer alone in the face of difficulties, but are able to cope with challenges together. Emotion management plays an important role in the mental health of college students. Learning to recognize and manage one's emotions is a skill that every college student should master. Through deep breathing, relaxation training, and other methods, they can effectively regulate their emotions and avoid the adverse effects of mood swings. At the same time, it is also important to find suitable ways to release emotions, such as confiding in your heart and writing a diary. Of course, when faced with serious mental health issues, college students should be brave enough to seek professional help. School counselling centres or professional counselling agencies can provide them with effective support and guidance. With the help of professionals, they can develop a personalized psychological intervention plan to address psychological problems and restore mental health. 
To sum up, the maintenance of college students' mental health is not an overnight process, but a long-term goal that requires the joint efforts of individuals, schools, families and society. Only by working together can we create a healthier and more harmonious growth environment for college students, and help them develop and grow in an all-round way. At the same time, all sectors of society need to continue to pay attention to the mental health problems of college students and provide them with necessary support and care. In this way, we can jointly cultivate a group of outstanding young talents with both knowledge and skills and a healthy attitude.
