The research shows that teenagers are wired to sleep late, yet most schools in the US start before 8:30 am. Sleep is largely dictated by your genes. Inside all mammals is a tiny region of the brain called the suprachiasmatic nucleus, or the SCN. The SCN is referred to as the body’s master clock, telling the body when to go to sleep and when to wake up. It actually shifts as you age -- and the biggest change happens to teenagers, making it tough for them to wake up for those early classes. But schools aren’t heeding the research. Most school schedules revolve around the typical 9 to 5 workday of adults, and so there is a general worry that pushing back when school starts will be too disruptive. What’s the solution?
