Sleep duration and cognitive performance are linked by a quadratic relationship where seven hours of sleep is associated with peak cognitive function, as evidenced by [1], [2], and [3]. This association is supported by large-scale data from the UK Biobank, which identifies sleep duration as a modifiable lifestyle factor influencing cognitive aging [4], [5], and [6].

Impact of sleep duration on executive function and brain structure nature.com 14 facts
accountThe researchers performed sensitivity analyses on individual cognitive test performance and sleep duration to address potential bias in missing data when comparing against the Executive Function latent variable.
claimThe study demonstrates that sleep duration is a modifiable lifestyle factor related to cognitive performance, which has implications for maintaining healthy cognitive aging in middle-to-late life individuals.
claimSeven hours of sleep per day is associated with the highest cognitive performance in middle-to-late life individuals, with performance decreasing for every hour of sleep below or above this duration.
claimThe negative cognitive effects of very short (two to three hours) and very long (11 to 12 hours) sleep durations are more apparent in younger participants (38–59 years) than in older participants (60–73 years).
claimIn the UK Biobank cohort, peak cognitive performance in middle-to-late healthy individuals is associated with seven hours of overnight sleep.
claimSleep duration and cognitive performance show cross-sectional associations in the UK Biobank population, according to a 2017 study in Sleep Medicine.
claimThe study on sleep duration and brain structure found that sleep duration is a modifiable lifestyle factor related to cognitive performance, with implications for maintaining healthy cognitive aging in middle-to-late life individuals.
claimThe six-to-eight hour sleep duration band used in the regression model was selected because seven hours of sleep is associated with the highest cognitive performance, and the one-hour buffer on either side accounts for self-reporting bias.
referenceLo, J. C., Loh, K. K., Zheng, H., Sim, S. K. Y., and Chee, M. W. L. found that sleep duration is associated with age-related changes in brain structure and cognitive performance in a 2014 study published in the journal Sleep.
measurementThe quadratic relationship between seven hours of sleep and optimal cognitive performance persists in individuals older than 60 years, based on an analysis of 212,006 individuals.
claimA multiple regression model using Executive Function as the dependent variable confirmed a quadratic relationship between sleep duration and cognitive performance, controlling for age, chronotype, insomnia, obstructive sleep apnoea traits, vascular co-morbidity, smoking, BMI, APOE ε4 genotype, and socioeconomic status.
referenceThe study examined the relationship between sleep duration and cognitive performance in 479,420 healthy individuals aged 38 to 73, using data from the UK Biobank.
claimSleep duration exhibits a quadratic relationship with cognitive performance, where performance worsens as sleep duration decreases from six to three hours or increases from eight to 12 hours.
referencePrevious studies using UK Biobank cognitive tests associated sleeping 10 hours or more (long sleep) and six hours or less (short sleep) with worse cognitive performance.

claimResearchers predict that normal sleep duration confers optimal long-term cognitive performance, while both insufficient sleep and prolonged sleep duration increase the risk of long-term cognitive decline in middle-aged and older adults.
