Summary: New research presented at the SLEEP 2025 meeting indicates that adolescents who use moderate catch-up sleep on weekends—up to two extra hours compared with weekdays—report fewer anxiety symptoms. By contrast, teens who sleep substantially more or less on weekends than during the week showed higher anxiety levels. These findings suggest a balanced weekend recovery sleep pattern may help reduce mental health risks associated with weekday sleep restriction.
With many teenagers not meeting recommended nightly sleep targets during school nights, understanding the optimal amount of weekend recovery sleep could inform healthier routines and targeted recommendations from parents, educators, and clinicians. This article summarizes the study methods, main findings, and practical takeaways for teens and caregivers.
Key findings
- Sleep sweet spot: Up to two additional hours of weekend sleep (versus weekdays) was linked with fewer anxiety symptoms.
- Too much or too little variability: Sleeping substantially more or less on weekends than on weekdays was associated with higher anxiety.
- Widespread short sleep: Only 23% of high school students achieve the recommended 8–10 hours of nightly sleep on an average school night.
Study overview
The research, led by doctoral candidate Sojeong Kim from the University of Oregon, evaluated sleep patterns and internalizing symptoms in 1,877 adolescents (mean age 13.5 years). Objective sleep duration was estimated with wrist-worn Fitbit devices, while internalizing symptoms—such as anxiety and depressive signs—were measured using the Child Behavior Checklist survey. Weekend catch-up sleep was calculated as the difference between average weekend and weekday sleep durations.

Main results and interpretation
The analysis showed that adolescents who extended their sleep on weekends by up to two hours experienced fewer anxiety symptoms compared to those with no weekend extension. However, larger swings—either sleeping much more on weekends or sleeping less—were associated with slightly higher internalizing symptoms. According to Kim, both extremes of weekend sleep variability can be detrimental: “The results show that both sleeping less on weekends than weekdays and sleeping substantially more on weekends were associated with higher anxiety symptoms.”
Kim added, “In contrast, moderate catch-up sleep — defined as less than two hours — was associated with lower anxiety symptoms, suggesting that some weekend recovery sleep may be beneficial.” The findings point to a potential “sweet spot” for weekend recovery that mitigates the psychological strain caused by insufficient weekday sleep without introducing greater variability that might itself be harmful.
Why this matters
The American Academy of Sleep Medicine recommends that teenagers aged 13–18 regularly obtain 8–10 hours of sleep for optimal health. Yet data from U.S. surveys indicate that the majority of adolescents fail to meet that threshold on school nights. Consistently adequate sleep supports attention, learning, emotional regulation, and overall physical and mental health, while chronic sleep deficiency in teens has been linked to higher risks of depression and suicidal thoughts.
For many adolescents, weekend “sleeping in” is a common strategy to compensate for weekday shortfall. This study suggests that limited catch-up sleep—about one to two extra hours—may help reduce anxiety-related symptoms without creating large swings in sleep patterns that could counteract benefits.
Practical recommendations
- Encourage consistent bed and wake times across the week when possible to reduce large variability in sleep patterns.
- If weekday schedules force shorter sleep, aim for modest weekend recovery (up to two extra hours) rather than dramatically different sleep schedules.
- Monitor overall sleep duration across the week, prioritizing the recommended 8–10 hours per night for teenagers whenever feasible.
- Discuss sleep concerns with a pediatrician or mental health professional when anxiety or mood symptoms persist.
Limitations and next steps
The study used objective sleep tracking and a well-established symptom checklist, strengthening the reliability of the findings. Still, observational data cannot prove causation, and additional research is needed to confirm ideal recovery strategies across diverse adolescent populations and to explore how sleep timing, quality, and consistency interact with mental health outcomes.
