Teenagers Facing Significant Decline in Sleep, New Report Reveals
A recent report published in the Journal of the American Medical Association indicates that teenagers are experiencing a significant decline in sleep.
Key Research Findings
Researchers analyzed data from approximately 121,000 high school students from the Youth Risk Behavior Survey to assess trends in insufficient sleep, defined as less than eight hours per night.
In 2023, about three out of four American adolescents across all demographics reported insufficient sleep, an 8% increase since 2007.
This trend was largely driven by an increase in teens getting five hours of sleep or less, a figure that rose from 15.8% to 23.0% during the same period.
Black students experienced a greater increase in insufficient sleep compared to white students, though widespread increases were observed across all age, sex, and racial/ethnic groups.
Interestingly, the rise in insufficient sleep did not appear to correlate with mental health symptoms, substance use, or daily hours spent watching TV or on social media. In fact, teens with minimal screen time showed a greater increase in insufficient sleep than those with heavy screen use.
Expert Commentary: An "Epidemic" of Sleep Deprivation
Tanner Bommersbach, a child and adolescent psychiatrist, highlighted the crucial role sleep plays in adolescent brain development, emotional regulation, and overall physical and mental health. Adequate sleep is vital for the developing brain and overall well-being.
While the exact causes for the widespread surge in sleep loss remain unclear, Bommersbach speculates that earlier school start times, increased extracurricular demands, and reduced parental monitoring may be contributing factors.
Anita Shelgikar, president of the American Academy of Sleep Medicine, characterized the issue as an "epidemic of adolescent sleep deprivation."
Recommendations for Improving Adolescent Sleep
Anita Shelgikar suggests several steps to improve adolescent sleep:
- Dimming lights and minimizing electronic use before bed.
- Maintaining a consistent sleep schedule.
- Ensuring a cool, dark, and quiet sleep environment.
- Getting exposure to bright light, particularly outdoor light, in the morning to signal wakefulness to the brain and regulate circadian rhythm.
Shelgikar also advocates for adults to model healthy sleep hygiene and integrate sleep health education into school curricula. Crucially, she recommends that schools consider delaying school start times, which research has shown can lead to more sleep and improved academic performance for teens.
