Chinese students often get insufficient sleep, averaging around 7-9 hours on weekdays, with university students averaging about 7.08 hours and high schoolers sometimes getting as little as 7.2 hours, significantly less than recommended guidelines (9-10 hours for younger, 8 for older). Many compensate by sleeping longer on weekends, but short weekday sleep, late bedtimes (often past midnight), and heavy academic loads, especially for the Gaokao exam, lead to widespread sleep deficiency, even resulting in napping in class.
The results showed that 29% of students had fairly bad or very bad sleep quality, and the average daily actual sleep time was 5.67 hours (SD =0.582). Male students (M =5.62, SD =0.645) had significantly less sleep time than female students (M =5.72, SD =0.509), with F=12.048 and P=0.001.
The pooled mean sleep duration of 21 studies with available data was 6.82 hours/day (95% CI: 6.59-7.05 hours/day). The estimated proportions of sleep duration <5 hours/day, <6 hours/day, <7 hours/day were 18.8% (95% CI: 1.7%-35.9%), 26.7% (95% CI: 19.7%-33.7%) and 42.3% (95% CI: 34.8%-49.8%), respectively.
