Professor Tsukasa Sasaki of the University of Tokyo Graduate School of Education, Tokyo Metropolitan Institute of Medical Science, and a research team at Kochi University say that teenagers need 10 hours of sleep to maintain their mental health. I found out.Most junior and senior high school students sleep less than this, and it seems that their habits need to be reviewed.

 According to the University of Tokyo, the survey analyzed answers to questions about average sleep time, depression, and anxiety symptoms on weekday nights, targeting about 2 junior and senior high school students in both Mie and Kochi prefectures.The subjects were divided into hours of sleep, and the proportion of people at risk of depression and anxiety symptoms was calculated, and the sleep time at which the risk of depression and anxiety symptoms was minimized was statistically calculated.

 The results showed that boys sleeping 8.5-9.5 hours and girls sleeping 7.5-8.5 hours had the lowest risk of depression and anxiety.
Furthermore, when the sleep time that minimizes the risk of depression and anxiety symptoms was calculated, it was found that boys had 8.8 hours for junior high school students, 8.5 hours for high school students, 8.0 hours for girls, and 7.5 hours for high school students.
The average sleep time for junior high and high school students is 1 hours for boys and 7.9 hours for girls in the first grade of junior high school, and 7.5 hours for boys and 3 hours for girls in the third grade of high school.Most of them have shorter sleep times than the least risk of symptoms of depression and anxiety, suggesting results that suggest a habit review.

 The relationship between sleep deprivation and mental disorders has been known for a long time, but in recent years, sleep time has been shortened due to changes in lifestyle.However, data analysis did not show how much sleep the children needed.
