When your alarm clock rings and you tell yourself to get out of bed, you probably wonder “Why on earth does school have to start so early?”
Luckily, there is a law to back you up, and it’s based on science.
A law in California, passed on 13 October 2019, requires that public middle schools begin classes no earlier than 8:00 a.m. and that high schools start no earlier than 8:30 a.m. The law went into effect on 1 July 2022.
Starting school at 8:00 or 8:30 in the morning may not sound like too big of a change, but it could mean one more hour of sleep for students who normally start school at 7:30 or even earlier.
“The effect of that one hour is something they will be feeling as 40-year-old adults,” Sumit Bhargava, a sleep expert at Stanford University said. He said that not having enough sleep can affect students’ mental health and increase the risk of obesity (肥胖) and diabetes (糖尿病).
In the short run, students’ academic performance should improve almost immediately. Kyla Wahlstrom, a researcher at the University of Minnesota’s College of Education, found that students who have enough sleep are better in class and get better grades.
Some might say that asking students to go to bed earlier could have been a much easier solution than changing the school timetable across an entire state. But according to the American Academy of Sleep Medicine, teenagers go through many changes as they grow up, which makes it difficult for them to fall asleep before 11:00 p.m. So when school starts at 8:00 or earlier, it’s hard for them to get the ideal 8.5-9.5 hours of sleep that experts suggest they need to do their best in the daytime.
When the law was approved, its author, Senator Anthony Portantino, said, “Generations of children will come to appreciate this historic day and our governor for taking brave action.”
