Anxiety and depression are the most common mental disorders. Due to their negative impact on work capability and performance, mental disorders have received widespread attention. When young people go to college, they experience a variety of stressors, such as leaving home and becoming independent, assuming new responsibilities, and embracing new academic challenges (1). In addition to the effects of academic and social lives and personal habits, this sudden independence brings numerous choices to students. As a result, many college students report increasing levels of stress and an inability to cope with their stressors, thus leading to an overwhelming feeling (2). Frequently, college students make sacrifices in some major aspects of life, and sleep quality is thus often neglected. To this end, early psychological interventions may contribute to the prevention of mental disorders (3). Moreover, the prevalence of mental health disorders varies widely among university students; in some countries, the prevalence of depressive symptoms reaches up to 50% (4). Therefore, it is necessary to develop a simple, economical, feasible and effective intervention for addressing mental health issues among university students.
