More than half of U.S. college students report at least one symptom consistent with insomnia, including 31.4% who report short sleep of 6 hours or less. In that same population, 11% report sleeping 5 hours or fewer per night. Studies also link sleep patterns to outcomes, including a school-based intervention that reduced daytime sleepiness by 3.1 points on the Epworth Sleepiness Scale.
Key Takeaways
- 11% of U.S. college students reported sleeping 5 or fewer hours per night
- 31.4% of U.S. college students reported short sleep duration (≤6 hours per night)
- 55.4% of U.S. college students reported at least one symptom consistent with insomnia
- One school-based sleep intervention reduced daytime sleepiness scores by 3.1 points (Epworth Sleepiness Scale) in a trial
- A systematic review reported that sleep extension programs improved academic performance measures by 0.2–0.3 SD
- In adolescents, sleep interventions were associated with a reduction of 0.4 standard deviations in behavioral problems in pooled analyses
- Adolescents who slept ≤7 hours had a 2.2-fold higher risk of depressive symptoms than those sleeping 9 hours
- Short sleep (<7 hours) was associated with a 1.55x higher risk of anxiety symptoms
- Insufficient sleep was reported by 24% of adolescents and was associated with increased risk of emotional/behavioral problems
- School start time policies are associated with improved sleep duration by 30 minutes or more in policy evaluation studies
- The 2023 U.S. Behavioral Risk Factor Surveillance System (BRFSS) reports insufficient sleep among adults at 21.6%
- The CDC Youth Risk Behavior Survey shows 35% of U.S. high school students reported sleeping ≤4 hours on an average school night (2019)
- Major consumer wearables shipments totaled 151.7 million units worldwide in 2023
- The global behavioral health software market size was $7.2 billion in 2022
- In a validation study, a wrist-worn actigraphy device estimated sleep time with mean absolute error of 38 minutes compared with polysomnography
Most students do not get enough sleep, harming mood, attention, and learning, though school interventions can help.
