Teenagers aren’t lazy.
They don’t sleep late because they’re slug-a-beds, who’s only enthusiasm is for sleeping as long as possible. Biologically, they can’t help themselves. And having to go to a high school where classes start far too early in the a.m. doesn’t help either.
The four worst years of my life coincided with the four years Sarcasmo spent in high school.
His school started at 7:20 in the a.m. That meant he got up at 6:15 and I got up 15 minutes later, just in case. I barely made it through those four years and I know for a fact that the early start made Sarcasmo even crankier than he normally would have been.
Researchers have found that during adolescence, as hormones surge and the brain develops, teenagers who regularly sleep eight to nine hours a night learn better and are less likely to be tardy, get in fights or sustain athletic injuries. Sleeping well can also help moderate their tendency toward impulsive or risky decision-making.
That’s all well and good, but what teenager have you met who will be getting a regular eight to nine hours of sleep? Not many. After all, it seems like they can’t even force themselves to bed before 11 or 12 at night. It turns out that the reason for that late bed time isn’t just because teenagers are, by nature, prickly and annoying.
During puberty, teenagers have a later release of the “sleep” hormone melatonin, which means they tend not to feel drowsy until around 11 p.m. That inclination can be further delayed by the stimulating blue light from electronic devices, which tricks the brain into sensing wakeful daylight, slowing the release of melatonin and the onset of sleep. A Minnesota study noted that 88 percent of the students kept a cellphone in their bedroom.
That’s only one of the reasons I’ve been advocating for years that high schools need to start their days later. Teenagers’ biology basically prevents them from going to bed early enough to get the requisite hours of sleep each night. By starting school early, the school districts force teenagers into being perpetually sleep deprived.
Sure, stating high school later in the day might make sports practices end later and cut into time for some extracurricular activities or after-school jobs, but I think it’s a sacrifice that’s worth making. After all, the job of high schoolers is to excel in high school, so they can get to college and learn what’s necessary to get a good job. That’s much easier to do if they’ve been getting enough sleep every night.
New evidence suggests that later high school starts have widespread benefits. Researchers at the University of Minnesota, funded by the Centers for Disease Control and Prevention, studied eight high schools in three states before and after they moved to later start times in recent years. In results released Wednesday they found that the later a school’s start time, the better off the students were on many measures, including mental health, car crash rates, attendance and, in some schools, grades and standardized test scores.
I think part of the problem with moving high school start times to later is that, for some reason, there’s this sense of being a macho manly type if you’re able to do without a lot of sleep. It’s as if folks believe that sleep is for weenies. Do we really need to start toughening up teenagers by depriving them of sleep and then demanding they perform as if they were well rested?
The University of Minnesota study tracked 9,000 high school students in five districts in Colorado, Wyoming and Minnesota before and after schools shifted start times. In those that originally started at 7:30 a.m., only a third of students said they were able to get eight or more hours of sleep. Students who got less than that reported significantly more symptoms of depression, and greater use of caffeine, alcohol and illegal drugs than better-rested peers.
“It’s biological — the mental health outcomes were identical from inner-city kids and affluent kids,” said Kyla Wahlstrom, a professor of educational research at the University of Minnesota and the lead author of the study.
If you’re a dude who, like me, thinks it’s time for schools to start actually making decisions that are good for their students, then you should head on over to Start School Later, an advocacy group for health and safety in education.Share on Facebook Tags: A Dude's Guide to Health, A Dude's Guide to Teens, Adolescence, Alcohol, Attendance, Bed Time, Caffeine, Centers For Disease Control And Prevention, decision-making, dude, education, Electronic Devices, health, High School Students, Hormone Melatonin, Hours Of Sleep, kids, Mental Health, Sacrifice, Sarcasmo, School Start Times, schools, sleeping, teenagers, Test Scores, University Of Minnesota
