Lifestyle Health Is Homework a Waste of Students' Time? Study Finds It's the Biggest Cause of Teen Stress As the debate over the need for homework continues, a new study found that it's the biggest cause of teen stress, leading to sleepless nights and poor academic performance By Julie Mazziotta Julie Mazziotta Twitter Associate Editor, PEOPLE Health People Editorial Guidelines Published on December 18, 2018 09:55 AM Share Tweet Pin Email Photo: Elva Etienne/Getty It’s the bane of every teen’s existence. After sitting through hours at school, they leave only to get started on mountains of homework. And educators are mixed on its effectiveness. Some say the practice reinforces what students learned during the day, while others argue that it put unnecessary stress on kids and parents, who are often stuck nagging or helping. According to a new study, conducted by the Better Sleep Council, that homework stress is the biggest source of frustration for teens, with 74 percent of those surveyed ranking it the highest, above self-esteem (51 percent) parental expectations (45 percent) and bullying (15 percent). Homework is taking up a large chunk of their time, too — around 15-plus hours a week, with about one-third of teens reporting that it’s closer to 20-plus hours. The stress and excessive homework adds up to lost sleep, the BSC says. According to the survey, 57 percent of teenagers said that they don’t get enough sleep, with 67 reporting that they get just five to seven hours a night — a far cry from the recommended eight to ten hours. The BSC says that their research shows that when teens feel more stressed, their sleep suffers. They go to sleep later, wake up earlier and have more trouble falling and staying asleep than less-stressed teens. “We’re finding that teenagers are experiencing this cycle where they sacrifice their sleep to spend extra time on homework, which gives them more stress — but they don’t get better grades,” said Mary Helen Rogers, the vice president of marketing and communications for the BSC.

To end this cycle of sleep deprivation and stress, the BSC recommends that students try setting a consistent time to go to sleep each night, regardless of leftover homework. And their other sleep tips are good for anyone, regardless of age — keep the temperature between 65 and 67 degrees, turn off the electronic devices before bed, make sure the mattress is comfy and reduce noise with earplugs or sound machines.
