The body operates on its own biological clock, also known as circadian rhythm. It helps determine how soon and how long a person needs to sleep to feel rested and energized for the next day. This clock is dynamic, and it changes depending on the stage a person is in.
The changes in sleeping patterns, for example, can vary between adolescents and younger children like elementary schoolers. While the latter may already be dozing off at 9:00 p.m., teens may still be up at 10:00 p.m. These differences in sleeping habits are now forcing schools to seriously consider adjusting their start times to a later period.
According to the American Academy of Pediatrics, teens need at least 8.5 hours of sleep every night to function well the next day. However, the average school time is 8:00 a.m., which means they get less than what is ideal. If this lifestyle continues or becomes chronic, the teen may eventually underperform in school. They may also be forced to use drugs or start drinking caffeine in order to stay awake. Some students, moreover, may exhibit signs that are similar to ADHD (attention deficit hypersensitivity disorder).
Other studies may seem to support the recommendation, as reported by Vox. For instance, Jackson High School, which moved their school time from 7:35 a.m. to 8:55 a.m. in 2012, discovered that more students are showing up to classes on schedule.
In an effort to help children perform better in school, public and school boards are now including changing school start times in their agenda while others are already starting to implement it. Some Toronto schools are already embracing the late start times, which resulted to marked improvements in attendance, math scores, and energy. Students tend to be more receptive and ready to learn. Cathy Dandy, a trustee, hopes that with more research, they can convince more schools to adopt the same change. In the United States, school districts in Seattle are studying it.
