Sleeping is Essential to Learning

Research has shown that teenagers have internal body clocks and hormones that make it hard for them to fall asleep before 11 p.m. and hard for them to wake up before 8 a.m. Most high schools start classes around 7:30a.m., so students have to wake up very early. A National Sleep Foundation survey found that up to 28 percent of high school students fall asleep during their first class. A few high schools have recognized this issue and moved their starting times to around 8:30 a.m. When they did this, test scores and attendance increased.
