Delayed School Start Time Associated With Improvements in Adolescent Behaviors: This study was conducted by Judith A. Owens, M.D., M.P.H., of the Hasbro Children’s Hospital. The experiment consisted on studying 201 students from a high school in Rhode Island. The class start time in this institution would be delayed 30 minutes from 8 to 8:30 a.m. When the study was over students reported more time of sleep, had more motivation and fatigue-related complaints reduced. Students had 45 minutes more of sleep each day helping them to have a better day at school and coming closer to the appropriate time of hours of sleep each night. I believe that based on studies like this one schools all over the world should start class times later improve their students lives.

Performing Under Sleep Deprivation: It’s In Your Genes: This next study presented was performed by Antoine Viola, Derk-Jan Dijk, and colleagues at University of Surrey’s Sleep Research Center. The purpose of the study was to know if the two variants (short or long) of the gene PERIOD3 influenced in morning and evening activity levels. This can later be connected to the influences these genes might have on performance by unrested individuals. The results of the study were that during the early hours of the morning individuals with the longer variant performed poorly on tests for attention and working memory. Also, only those possessing the longer variant of the gene had 50% more deep sleep than the rest. I believe that these findings are very interesting and important to have fewer accidents during the night shift workers. With these results companies can choose their night shift workers correctly.

High School Students With A Delayed School Start Time Sleep Longer, Report Less Daytime Sleepiness: This study was conducted by Zaw W. Htwe, MD, of Norwalk Hospital’s Sleep Disorders Center. The study was on 259 high school students who answered a questionnaire of school sleep habits. This study was made to compare the results of the students before and after a 40 minute delay school start time. At first they reported sleeping a mean of 7.03 hours per school night, with a mean of bed time from 10:52 to a wake-up time of 6:12. After the 40 minute delay school start time student sleep time increased 33 minutes and they utilized 83% of the extra time for sleep. This study shows us that students will sleep longer if they are given the opportunity. I believe that schools should make these changes to their schedules to improve the efficiency and hours of sleep of their students.
