In order to understand the current status of sleep quality of students in Chengdu University of Traditional Chinese Medicine, and to propose countermeasures. A simple random sampling method was used to select 255 university students as the survey subjects, and Pittsburgh Sleep Quality Index (PSQI) scale was used as a tool to evaluate the quality of college students' sleep. The survey found that the average score of PSQI was about 7.6 points. There were 128 people above 7 points, which accounted for 50.2% of the total number of students. This indicated that the overall quality of sleep of the undergraduates was poorer; the quality of sleep for boys was better than that of girls, and the quality of sleep among rural college students was better than that of girls. Urban college students, seniors and undergraduates have worse sleep than sophomores and juniors. The sleep quality of students in Chengdu University of Traditional Chinese Medicine is generally poor, and it is necessary to implement measures that target different populations for different demographic differences to achieve proper treatment and improve sleep quality.
