Shorter self-reported sleep duration is linearly associated with prevalent and persistent psychological distress in young adults, with each hour less of sleep increasing the risk of distress persistence.
If you are a young adult (17-24) struggling with persistent low mood or anxiety, your sleep duration matters significantly. Each hour of sleep you lose increases your risk of maintaining that distress. Prioritize getting 8-9 hours of sleep, as this is the reference range associated with the lowest risk of psychological distress in this demographic.
Shorter sleep duration was linearly associated with prevalent psychological distress: relative risk (RR) 1.14 (95%CI 1.12 to 1.15)... Each hour less of sleep increased the risk of psychological distress persisting after adjustment for potential confounding variables: RR 1.05 (95%CI 1.01 to 1.10).
Why this rating
Large prospective cohort study (n=20,822 baseline, n=2,937 follow-up) with rigorous adjustment for confounders.
