Because researchers studying circadian rhythms have discovered that most teenagers are really nocturnal, school administrators should take this into account when organizing a school day. For example, traditionally teenagers must arise in the predawn hours and arrive at school before sunrise. Groggy and unfocused, they find it difficult to concentrate and be alert before lunch. After lunch, which for many students in overcrowded high schools begins at 10:30 a.m., they are finally able to pay attention. Armed with this information, the school board should be innovative and rearrange the schedule, which would curb truancy in grades 8 through 12.
By adjusting the start time of high schools to later in the morning, students would be more awake, alert, and ready to learn. This shift could lead to improved academic performance, better attendance, and overall student well-being.
Additionally, extracurricular activities and sports could also benefit from a later start time, as students would have more energy and focus to participate fully. Teachers might also notice a decrease in behavioral issues, as students would be more engaged and attentive in the classroom.
Furthermore, parents may find it easier to get their teenagers out of bed in the morning, as they would be more likely to have had a restful night's sleep. This could lead to less stress and conflict at home.
Overall, taking into consideration the natural nocturnal tendencies of teenagers and adjusting school schedules accordingly could have a positive impact on the academic success and overall well-being of students in grades 8 through 12.
