Abstract: Stressors are stimulus or variation cause to stress response, and the stress has an adverse effect on the sleep quality. Referring to the stressors that affect sleep quality, most of recent researches mainly focus on the following five traditional stress dimensions: family, academic, work, social-culture and disease. The relationship between these stressors and sleep quality is bidirectional and complex, direct and indirect, which could be changed by the duration and the intensity. In addition, the individual difference is reflected by the mediators and moderators.

Key words: mental health, stress, stressor, sleep quality, theory model for the "stress-sleep" relationship
