Background: During adolescence, sleep is an important activity that affects growth, learning, and personality formation. However, many Korean high school students do not get enough sleep and exercise when they prepare for college entrance examinations. This study investigated the relationship between physical activity and sleep satisfaction.
Methods: Korean high school students with high sleep satisfaction and physical activity were identified with the 2015 Youth Health Behavior Online Survey. Physical activity was categorized as over 60-minute moderate physical activity, over 20-minute vigorous physical activity, and muscle strengthening exercises.
Results: The study, which involved 27,097 high school students, showed that sleep satisfaction was significantly higher in boys than in girls and significantly lower in 3rd grade students compared with students in the other grades. Sleep satisfaction significantly increased with only 1–2 episodes/wk of exercise in the groups doing over 20-minute vigorous physical activity and muscle strengthening exercises compared to the students getting no exercise. The sleep satisfaction of students who got over 8 hours of sleep did not differ on exercise days, and, regardless of their exercise days, these students reported adequate average sleep satisfaction, which suggested that sleep satisfaction was higher when students got physical activity and enough sleep.
Conclusion: The sleep satisfaction of high school students improved when they got enough sleep and physical activity. In addition, improved educational environment and active medical interventions were required.
