Teens from thirteen to eighteen should get about eight to ten hours of sleep every night” (John Higgins). If the start time is pushed back, students could get the 8-10 hours needed to sleep. If not, they will continue to go to school sleep deprived. After recent studies were done in the U.S. and the U.K., they found that school-age children were losing, on average, 10 hours of sleep a week. This was due to a combination of late-night studying and early-morning wake-up calls to get to school (school start times). This implies how much early start times affect the amount of sleep children are getting. Did you know 75.4 percent of high school students in the United States get less than eight hours of sleep (school start times)? They also found that 43 percent slept less than six hours. This means that over 34 of students aren't getting the sleep they need to function at a high rate. As you can see, the school start times mess with students' sleep schedules and bodies. This leads to many problems, which is why school start times need to be pushed
