Back to School and Back to Bed: Why Good Sleep Is Essential for Student Success
As summer winds down and the back-to-school season approaches, many families focus on school supplies, new clothes, and adjusting daily routines. But one of the most critical—yet often overlooked—parts of preparing for a successful school year is getting enough sleep.
Sleep is essential for growing minds and bodies. Research consistently shows that children and teens who get the right amount of rest are more focused, perform better in school, and have improved emotional well-being. Unfortunately, many Iowa students are falling short of the recommended sleep guidelines.
Alarming Sleep Statistics in Iowa
According to recent data:
31% of Iowa elementary and middle school students report not getting enough sleep on school nights.
An even more concerning 73% of Iowa high school students report insufficient sleep during the school week.
These numbers highlight a growing public health concern. As school start times and extracurricular demands push schedules earlier and later, students are sacrificing precious hours of rest—often without fully understanding the consequences.
Why Sleep Matters for Students
Adequate sleep fuels every part of a child’s development:
Cognitive function: Sleep supports memory, problem-solving, and attention span—crucial skills for academic performance.
Mood and behavior: Well-rested students are less likely to experience mood swings, anxiety, or behavioral issues.
Physical health: Sleep boosts the immune system and supports healthy growth and development.
Safety: Tired teens are more prone to accidents, both on the road and in daily life.
How Much Sleep Do Kids Need?
The American Academy of Sleep Medicine recommends:
9–12 hours per night for children ages 6–12
8–10 hours per night for teens ages 13–18
Many students are getting one to two hours less than these recommended amounts, every night. Over time, this sleep debt can have serious impacts.
Tips for Better School-Year Sleep
As school starts back up, here are some strategies for helping kids get the rest they need:
Set a consistent bedtime and wake time, even on weekends.
Limit screen time at least an hour before bed. Blue light from devices can interfere with the body’s natural sleep signals.
Create a calming bedtime routine, like reading or listening to soft music.
Keep bedrooms cool, quiet, and dark, making it easier to fall and stay asleep.
Advocate for healthy school start times. Research supports later start times for teens to align better with their natural sleep cycles.
A Call to Action
Good sleep isn’t a luxury—it’s a necessity for learning, development, and emotional health. As we prepare Iowa students for a successful school year, let’s not forget the power of a good night’s sleep. Encouraging healthy sleep habits now can make all the difference in the classroom—and beyond.
