Should school start later?
In October 2014, the American Academy of Pediatrics (AAP) issued a policy statement suggesting that school districts consider starting school after 8:30am. Currently, some schools start as early as 7am. With the option of a 0 period, or an optional class before 1st period, it can be even earlier. One reason for this schedule is a consideration for parents' work schedules, making it easy for parents to drive their kids to school. Many argue, however, that teenagers and adults do not function on the same sleep schedule. They say that students can find other ways to get to school: a small price to pay for getting enough sleep.
The proposal to push back when first period begins comes from concerns that starting school too early negatively affects teenagers. Studies have shown that middle and high school students with adequate amounts of sleep, 8-10 hours, have better test scores. This subject has been debated heavily since schools began starting earlier and earlier.
The AAP study found that most teenagers need sufficient sleep to cope with busy lives filled with school, sports, and extracurricular activities. According to this research, the ideal amount of sleep for the average teenager falls between 8.5 and 9.5 hours a night, and teenagers who receive adequate sleep benefit from better physical and mental health, safety, and academic performance. It also revealed that puberty causes a “phase delay” in teenagers, which shifts the time that teenagers fall asleep back by two hours. Because of this, the average teenager is expected to fall asleep after 11pm and wake up around 8am.
When students do not get enough hours of sleep due to the phase delay and waking up early, it can have a long term impact on students' health. A National Sleep Foundation poll reported that 28 percent of teenagers have fallen asleep in class at least once due to lack of sleep. Negative effects of sleep loss include impairments in mood, attention, memory, behavior and executive function. In addition, a lack of sleep may lead to an increase in caffeine use to counter the effects of drowsiness. Finally, this study found that sleep-deprived teens are at a higher risk of car accidents.
Many researchers agree that starting the school day later might be beneficial to young people. Lawrence Epstein, a medical director of Sleep Health Centers in Brighton, Massachusetts and an instructor of medicine at Harvard Medical School, believes that “adequate sleep is essential to feeling awake and alert, maintaining good health, and working at peak performance.” Starting later can allow youth to get the necessary amount of sleep, which is due to the natural late-to-bed and late-to-rise biology of teenagers. According to the American Academy of Sleep Medicine, “Students with symptoms of sleep disorders are more likely to receive poor grades in classes such as math, reading and writing than peers without symptoms of sleep disorders.” Getting enough sleep might lead to a decreased risk of car accidents, less depression and obesity, the prevention of illnesses like colds and flus that adversely affect academic performance, and generally improved mental ability. Although students can get more sleep by simply going to bed earlier, many need this time to finish homework. With a later school start time, students can have both: adequate time to prepare for the next day and a sufficient amount of sleep.
