Today's topic is "Study: Starting School Late Improves Health and Grades" A 2017 study at an English high school found that students who started school at 10 a.m. instead of 8:50 a.m. had better health and school results. For the first year of the study, the students started school at 8:50 a.m. For the second and third years, their start time changed to 10 a.m. Then, for the fourth year, the students went back to starting at 8:50 a.m. The researchers looked at how often students stayed home from school due to illness, and how well they did with their school work. For the first year, the average number of absences due to illness was 15.4 per student. In the second year, that number dropped to 11.3, and by the third year it was just 7.9. But in the fourth year, when the students went back to starting at 8:50 a.m., the number went up to 11.2. The students' school work also improved. By the end of the first year, only 34% of the students had a grade of C or higher in five or more of their GCSEs — General Certificate of Secondary Education subjects, which need to be taken by most students in the UK. By the end of the second year, 53% of students had a C or higher in five or more of their GCSEs. The number went down to 52% in the third year, and 51% in the fourth year. Professor Russell Foster, of Oxford University, says that teenagers need 9 hours of sleep, but many only get 5 hours on a school night. 🍀SNS instagram:https://www.instagram.com/kidslovejapan/ twitter: https://twitter.com/KidsLove_Japan/ facebook: https://www.facebook.com/gmsi.jp/ WorldNews:https://anchor.fm/worldnews/ Tumblr: https://www.tumblr.com/blog/kidslove-japan/ blog: http://masako-toybox.seesaa.net/ ✅SUBSCRIBE https://www.youtube.com/channel/UCHl6jliVGhN3z978Rh1L-AQ?sub_confirmation=1 #WorldNews #AudioNews
