Korean students' sleep duration varies significantly by their grade level, with younger students typically sleeping more hours than those in higher grades.
Understanding Sleep Patterns Among Korean Students
The average sleep time for Korean students on schooldays shows a noticeable decrease as they advance through their education. This trend highlights a diminution in sleep time for students in higher grades.
The sleep duration, measured as net total sleep time (nTST), is as follows:
| Grade Level | Average Sleep Duration on Schooldays |
|---|---|
| 5th-6th Graders | 7 hours 57 minutes (± 1 hour 3 minutes) |
| 7th-9th Graders | 7 hours 34 minutes (± 1 hour 3 minutes) |
| 10th-12th Graders | 5 hours 47 minutes (± 1 hour 8 minutes) |
This data indicates that while elementary and middle school students generally get over seven hours of sleep, high school students (10th-12th graders) average significantly less, often just under six hours. This diminishing sleep time in higher grades is a notable characteristic of sleep patterns among Korean students.
