Why Sleep Matters for Teens with Type 1 Diabetes—and What Gets in the Way

Sleep is foundational to health—it affects everything from immune function to mood to academic performance. Yet adolescents with Type 1 diabetes face unique obstacles to getting enough rest. A new mixed-methods study of 70 teens found that more than half are not meeting the American Academy of Sleep Medicine's sleep recommendations.

The research, published in Hormone Research in Paediatrics, examined sleep patterns, barriers, and experiences among adolescents ages 11 to 17. Using a combination of sleep tracking devices, sleep diaries, surveys, and interviews, researchers built a comprehensive picture of what's really happening at night for these teens.

On average, the study participants slept 7.1 hours per night—about an hour less than most adolescents need. The problem was especially pronounced in older teens: as adolescents got older, their sleep duration decreased significantly. Teens who weren't getting enough sleep also had lower sleep efficiency, meaning they spent less of their time in bed actually sleeping.

Interestingly, most of the teens reported feeling their sleep quality was good. This disconnect—between objectively measured sleep duration and perceived sleep quality—is an important finding. It suggests that many teens may not realize how much their sleep is being reduced or how it affects them.

When researchers asked teens directly about sleep barriers, school and extracurricular activities topped the list. Sports, clubs, homework, and school schedules are the dominant demands on adolescent time, crowding out opportunities for adequate sleep.

Diabetes-related factors also played a role, though not as the primary barrier. Nighttime glucose management, alarms from continuous glucose monitors and insulin pumps, and fear of low blood sugar during sleep all contributed to sleep disruptions and awakenings. These diabetes-specific challenges layer onto the already-busy lives of teens.

Although this particular study did not find a direct correlation between sleep duration and blood sugar control in the short term, other research has established that poor sleep is linked to worse diabetes management and health outcomes over time. Sleep affects how the body regulates blood sugar, manages stress hormones, and handles insulin.

Teens themselves recognized the importance of better sleep. During interviews, many expressed interest in receiving recommendations and support for improving their sleep habits. This openness suggests that families and healthcare teams have an opportunity to address sleep as part of diabetes care.

The study highlights a gap in current diabetes care: sleep assessment is rarely part of routine clinic visits, even though sleep health is critical to overall well-being. The findings suggest that healthcare providers should ask teens and families about sleep patterns and barriers, and work together to find solutions.

For families, this research is a reminder that sleep isn't a luxury—it's a health necessity. Whether the barrier is school demands, diabetes management, or both, prioritizing adequate sleep alongside diabetes care is worth the effort.
