Do You Think 7:35am Is an Appropriate Time to Start School?
Do you remember the last time you felt truly awake during your first-period class? For many students, early school start times like 7:35am mean dragging themselves out of bed long before the sun rises, squinting at textbooks under fluorescent lights, and struggling to focus on lessons while their brains are still half-asleep. The debate over school start times isn’t new, but it’s gaining fresh urgency as parents, educators, and researchers question whether early schedules align with students’ biological needs—or if they’re setting kids up for burnout.
Let’s unpack why 7:35am has become the norm for many schools, what science says about teen sleep patterns, and whether pushing back the morning bell could lead to healthier, more engaged students.
The Science Behind Teen Sleep Cycles
During adolescence, biological changes shift a teenager’s circadian rhythm—the internal “clock” that regulates sleep and wakefulness. Melatonin, the hormone that signals sleepiness, starts releasing later at night for teens compared to younger children or adults. This means a 16-year-old might not feel tired until 11pm or midnight, even if they need 8–10 hours of sleep for optimal health. Waking up at 6:30am to make a 7:35am start time? That’s a recipe for chronic sleep deprivation.
Studies consistently show that sleep-deprived teens face higher risks of anxiety, depression, obesity, and even car accidents. A landmark report by the American Academy of Pediatrics recommended that middle and high schools start no earlier than 8:30am to align with students’ natural sleep-wake cycles. Yet, many districts still cling to pre-8am schedules, citing logistical challenges or tradition.
Why Do Schools Start So Early?
The 7:35am start time isn’t arbitrary. It often stems from:
1. Transportation logistics: Staggered start times allow districts to reuse buses for multiple grade levels.
2. Extracurricular activities: Earlier dismissal leaves more daylight hours for sports or part-time jobs.
3. Parent work schedules: Some argue that earlier school days align better with typical 9-to-5 jobs.
But these arguments overlook a critical question: Are we prioritizing convenience over student well-being? A 2022 study by the University of Minnesota found that schools starting at 8:30am or later saw improved attendance, higher test scores, and fewer disciplinary issues. When students are well-rested, they’re more likely to engage in class and retain information—benefits that could outweigh the hassle of adjusting bus routes.
The Case Against 7:35am
Imagine a math class where half the students are zoning out, a science lab where safety depends on alertness, or a literature discussion where no one has the energy to analyze metaphors. Early start times don’t just affect academic performance; they also impact social and emotional health.
One high school junior shared anonymously: “I’m up by 6am, but my brain doesn’t ‘turn on’ until third period. By then, I’ve already missed key lessons.” Another student described falling asleep during exams despite studying all night. These stories aren’t outliers—they reflect a systemic issue.
Teachers notice it too. A history instructor in Ohio remarked, “The first hour feels like teaching to zombies. The real learning happens after lunch.”
Is 7:35am a Reasonable Compromise?
Some communities defend early start times as a middle ground. For example, districts that begin at 7:35am might argue they’re “only” 55 minutes earlier than the recommended 8:30am. But those minutes matter. A 2018 study in Sleep Health found that every 15-minute delay in start times correlated with measurable improvements in mood and focus.
Critics also point to screen time and homework loads as bigger culprits for sleep loss. While evening habits do play a role, research suggests that biology—not just Netflix—drives teens’ late-night tendencies. Expecting adolescents to “just go to bed earlier” ignores their shifting internal clocks.
What Would Change Look Like?
Shifting school schedules requires creativity. Some districts have adopted hybrid models:
– Later starts for older students: High schools begin at 8:30am, while elementary schools (whose students naturally wake earlier) start at 7:45am.
– Flexible first periods: Offering optional study halls or low-stakes classes during the earliest slot.
– Community partnerships: Coordinating with local businesses to adjust part-time work hours for teens.
In 2016, Seattle Public Schools shifted high school start times from 7:50am to 8:45am. Despite initial pushback, students averaged 34 extra minutes of sleep per night, and graduation rates climbed.
Final Thoughts
The 7:35am debate isn’t just about clocks and bells—it’s about rethinking how schools can adapt to the realities of adolescent development. While change won’t happen overnight (pun intended), the growing body of research makes a compelling case: Later start times aren’t a luxury; they’re a necessity for fostering healthier, more successful students.
As one parent put it, “If we know better, we should do better.” Maybe it’s time to let teenagers sleep in—at least until the sun comes up.
