Not Getting Enough Sleep Because Of Homework

My 16-year-old daughter is finally entering the homestretch of sophomore year, and she has been chronically sleep deprived since September. The reasons are multiple but when you add together 45 minutes of homework per class per night, plus a few extra-curricular activities, plus the downtime spent everyday watching a John Green video on YouTube or chatting with friends, and a normal amount of procrastination, it adds up to between 5 and 7 hours of sleep on an average school night. Throw in a term paper or heavy exam week and the average can easily drop to 3 or 4.

My daughter is hardly atypical. In fact, multiple studies have shown that the vast majority of teens today are living with borderline to severe sleep deprivation. According to sleep expert Dr. Mary Carskadon, a professor of psychiatry at Brown University and director of chronobiology and sleep research at Bradley Hospital in Providence, Rhode Island, teenagers actually need more sleep than younger kids, not less. Nine and a quarter hours of sleep is what they need to be optimally alert. According to a 2010 large-scale study published in The Journal of Adolescent Health, a scant 8% of US high school students get the recommended amount of sleep. Some 23% get six hours of sleep on an average school night and 10% get only 5 hours.

In studies conducted by Carskadon, half the teens she evaluated were so tired in the morning that they showed the same symptoms as patients with narcolepsy, a major sleep disorder in which the patient nods off and falls directly into REM sleep.

When you consider the fact that many of these kids are getting behind the wheel in the early morning and driving themselves to school, the issue of sleep becomes literally a matter of life and death.

What’s going on here?

So what exactly is keeping teenagers up so late? Unfortunately biology, technology, and societal expectations together create a perfect storm for the chronic sleep deprivation. The major contributors to adolescent sleep debt come down to these:

Biology

Along with the more obvious hormonal changes that transform your child into a teen, are shifts in the production of melatonin, the sleep hormone. That is why your teenager actually seems more awake at midnight than at dinner and left alone would probably sleep until ten or eleven. It may drive you crazy but, says Dr. Max Van Gilder, a pediatrician in Manhattan, “that is the normal circadian rhythm for 15- to 22-year-olds.” Effectively, they are in a different time zone than the rest of us.

“It’s a major contributing factor to sleep deprivation which is unique to adolescence,” says Dr. Allison Baker, a child and adolescent psychiatrist. “The typical high school student’s natural time to fall asleep is 11pm or later. We really need to adjust the environment instead of asking teenagers to adjust their physiology.”

The problem is compounded when many adolescents, like my daughter, try to make up for lost sleep on the weekends, sometimes sleeping upwards of 12 hours on Friday and Saturday nights, which only further disrupts their sleep cycle. But who has the heart to wake them?

Technology

It’s not just that Facebook, Twitter, Instagram, Tumblr and YouTube are distractions that keep kids up later, it’s the actual light coming off all the electronic devices they’re exposed to, especially late at night. Electronics emit a glow called blue light that has a particular frequency. When it hits receptors in the eye, says Dr. Van Gilder, “those receptors send a signal to the brain which suppresses the production of melatonin and keeps kids from feeling tired. And adolescents are low on melatonin and start producing it later to begin with.” Dr. Van Gilder says he’s seen adolescent bedtimes pushed back an hour to an hour and a half over the years since teens started doing their homework on computers. “On average, my teenage patients are going to bed at around 12:30 now.”

Teens who are up late writing papers on computers or chatting with their friends are effectively creating an even more stimulating environment that will only keep them from being able to fall asleep when they want to.

Homework

Andrea Pincus and Andrew Multer consider it a good night when their 16 year-old son, Jake Multer, a sophomore at The Dalton School in Manhattan, gets to bed by 12:30. And there’s lots of fighting that goes on around the issue of homework and bedtime. “He tells us we micromanage him,” Pincus says. “He tells us we’re helicopter parents, but does he mention he stays up until 5 or 6am writing a paper?” Pincus and her husband are torn between making Jake go to bed and encouraging him to finish his work regardless of how long it takes. “There’s the anxiety of a kid like Jake who cares about the work. He works with a very nice group of kids on certain assignments and it’s great that they have each other but they also on some level add to the anxiety because you always have one kid who’s staying up later or pulling an all-nighter, putting in more work on a paper or studying for a test and it creates this extra anxiety and competition.”

His brother Sam, 13 and an eighth grader at Hunter College High School in Manhattan, is more or less resigned to being sleep deprived. He figures his current bedtime—anywhere between 11pm and 12:30am—which is so late “for the most part due to homework,” will only get later as he gets older. He says his parents want him to go to bed earlier but “they recognize that if I did that I wouldn’t get my work done and it’s important to me and it’s important to them.” Sam however also admits to having a procrastination and time management problem, some of which he believes comes from being so tired in the afternoon.

Overscheduling

We live in a culture that values activity over sleep and there is no part of that culture that reinforces that idea more than the college admissions process. Teens are constantly being told that they have to be “well-rounded” which, in an age when colleges are becoming ever more selective means that the more they do, the better their applications will look. And for some kids, being involved in a lot of extracurricular activities may truly be a matter of pursuing a diversity of passions. Either way, the result is an ever-narrowing window for sleep.

Katrina Karl, 16, is finishing up her junior year at Joel Barlow High School in Redding, Connecticut. She takes 5 academic classes, participates in the three theatrical productions her school puts on every year and volunteers at the middle school in her town. On top of that she works 13 hours a week at a local grocery store to help pay for summer theater camp and to save money for college. This past year, she says, was brutal. “I was lucky if I got 4 to 5 hours of sleep a night,” she says. On the nights she worked, Karl wouldn’t get home until 9 or 10 o’clock. Then she would start doing several hours of homework. Katrina’s bus picks her up at 6:15am and the first period bell rings at 7:20am.

Karl says she’s been living this way since about halfway through freshman year. “Everyone at my school is exhausted,” she says.

Earlier School Start Times

Very early high school start times, like Karl’s, are not uncommon, despite the fact that they run completely counter to the biological needs of adolescents. “Multiple studies have shown that high school students aren’t functional before 9 am,” says Dr. Van Gilder.

Cathi Hanauer, an author and the editor of the anthology The Bitch In The House, has been at the center of a 7-year battle to change the 7:20 start time of her North Hampton, Massachusetts, high school. “It started before my daughter got to high school. She’s now one year out of college. My son is a sophomore. The resistance has been huge,” she says, “despite the fact that 60% of the students are falling asleep in school.”

According to Hanauer, it all comes down to bussing and sports. The school buses used for the high school are used for the middle and elementary schools that have later start times. Pushing back the start time for the high school would mean either making the younger kids get up earlier or adding more buses which is not in the school budget. Then there are concerns that later start times will compromise the practices of sports teams.

Hanauer and some of the other parents got a consultant in who designed an affordable busing plan and in 2013 the school board finally passed a resolution to move the high school’s start time to between 8:00 and 8:30. They have since overturned the decision. “I’m done,” Hanauer says. “It’s been the most frustrating thing I’ve ever been involved with.”

With more than half of American teenagers living with chronic sleep deprivation, parents and teachers tend to overlook the profound effects it has on kids’ physical, mental and behavioral health. The sleep deficit is not in fact, a normal part of being a teenager. It’s part of an invisible epidemic that we need to start addressing.

People say that homework is supposed to help children in school. Homework,however actually can worsen a child’s grades. Homework has many side effects, some of which are dangerous. A clear side effect of too much homework is lack of sleep. Many students do poorly on exams because of sleep deprivation.

 

Research showed that students did not think homework was useful and regarded homework as a burden. Students felt pressured to do homework instead of visiting family and participating in activities they used to enjoy. According to research, “56 percent of the students considered homework a primary source[of sleep deprivation]. Forty-three percent viewed tests as a primary stressor, while 33 percent put the pressure to get good grades in that category. Less than 1 percent of the students said homework was not a stressor.”(healthline.com)Ms. Pope; a researcher said that said the “magic number when it comes to homework is 'nothing over two hours' for highs school and 'no more than 90 minutes' in middle school.”(dailymail.co)As the diagram on the left shows, most students surveyed spent one to two hours each night doing homework. At Wilmington High School and other schools in Massachusetts, that was not always the case.


To prove what research says is true there, was an informal study I conducted that proves students spend too much time on homework and do not always get enough sleep. There was a survey given out to various students in different grades. The results were varied, depending on grade and school. The survey was given out to students both at Wilmington High School and other schools and towns. Students from Wilmington High School said that they did not get enough sleep and knew they needed more sleep. Students at Wilmington High School did around two to three hours of homework per night. Most students were still able to do activities, but by doing extra curricular activities students said they were up later doing their homework. Most Wilmington students got six to seven hours of sleep, but studies show that kids should get eight hours of sleep. See table below for more data.

Students from other towns got roughly the same amount of homework as kids from Wilmington High School, which was two to three hours. All of the students said that they had time for activities, but sometimes they had to spend extra time on homework. The students that go to other schools got around six to seven hours of sleep per night. Wilmington High School students and other students from other schools did not differ in terms of  homework, activities, and sleeping. They both spent around two to three hours on homework with time for activities and got around six to seven hours of sleep. See table below for more data.

One researcher showed the number of hours spent doing homework and the number of hours spent sleeping.This researcher surveyed sophomores. Most sophomores surveyed did two to under four hours of homework, but some students did have more than that. Four students surveyed had eight or more hours of homework to do. The researcher also surveyed the sophomores on how many hours of sleep they got. More than half of the sophomores got seven or less hours of sleep per night.(see diagram to the right) Another researcher surveyed 102 students. 52 students said that they got five to six hours of sleep on a weeknight. Only one student said that he or she got more than nine hours of sleep. On a weekend 48 students got seven to eight hours of sleep. Students spent the weekend catching up on homework and sleep. The researcher also asked the students what were their reason for giving  up sleep was. 86 out of the 102 students said that it was because they were finishing up homework. 57 students said they lost sleep because they were studying for a test. For more information look at the picture to the right.
Teachers give students too much homework. Students do not get enough sleep because they are trying to finish homework or they are studying. Researchers say high school students should get no more than two hours of homework per night. Most students got more than two hours of homework per night and this caused them to lose precious sleep time.


Homework also causes students mental and physical health to deteriorate. Students are putting their health at risk trying to finish homework. “Teens who have more homework than they can handle may become disillusioned with school and may lose the motivation to work hard,” says Gerald LeTendre, head of Penn State’s Education Policy Studies department.( livestrong.com) Research done by Australian researchers clearly suggested that placing too much homework can cause lower grades and even lead pupils to begin suffering from depression.(factualfacts.com) Homework also causes scholars to become less physically active. When teens are not physically active it can lead to obesity and other health related problems.(livestrong.com) Homework affects teens mental and physical health.
Homework causes many problems for students. These problems include sleep deprivation, lack of physical activity, and poor mental health. Students should get about two hours of homework and eight hours of sleep. Some of the homework assigned, is found useless by students. Homework would be more beneficial if the homework assigned was usefull.
