The UK Biobank serves as the primary data source for numerous studies investigating the relationship between sleep duration and various health outcomes, including cognitive performance and brain structure, as evidenced by [1], [2], and [3]. Researchers utilize the UK Biobank cohort to analyze sleep duration patterns, such as the median of seven hours identified in [4] and [5], and to assess the impact of sleep on cognitive ageing and neuroimaging metrics as described in [6] and [7].

claimAfter controlling for age using a quantile-based, age-residual analysis, seven hours of sleep was associated with the highest Executive Function score in the UK Biobank cohort.
claimSleep duration remained stable across the age range of the UK Biobank cohort, centered around a median of seven hours.
claimSleeping between six-to-eight hours is associated with greater grey matter volume in frontal, temporal, parietal, and cerebellar brain regions, according to the largest neuroimaging study to date using the UK Biobank cohort.
claimThe UK Biobank is releasing actigraphy data intended to improve the resolution of sleep duration measurements and provide information about sleep quality for future studies.
measurementThe UK Biobank study measured subjective sleep duration in discrete one-hour blocks, a method that included daytime naps and resulted in a relatively insensitive measure of sleep.
claimThe association between sleep duration and cognition is stronger in younger individuals but remains present in participants over 60 years old, based on analysis of the UK Biobank cohort.
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.
measurementThe study of sleep duration and cognitive function in the UK Biobank analyzed data from 479,420 middle-to-late life individuals aged 38–73 years.
measurementA sub-group of 37,553 individuals from the UK Biobank study was analyzed to determine the relationship between sleep duration and brain structure.
measurementThe median self-reported daily sleep duration for the 479,420 individuals in the UK Biobank cohort was seven hours.
measurementIn a study of 37,553 UK Biobank participants, 46 brain regions were significantly larger in volume in individuals who slept between six and eight hours compared to those with other sleep durations, including the orbital frontal cortex, pre-and post-central gyri, right frontal pole, hippocampi, and thalami.
procedureThe UK Biobank study measured sleep duration by asking participants to report the number of hours they sleep every 24 hours, with data collected during the initial UK Biobank assessment and again for participants who attended the imaging visit.
referenceA mendelian randomisation study on the UK Biobank cohort suggests that an optimal sleep duration exists to impact daily cognitive function and healthy cognitive ageing.
claimThe study of sleep duration and brain structure analyzed cross-sectional data from the UK Biobank cohort, which consists of individuals with a higher socioeconomic baseline and fewer comorbid diseases compared to the general population.
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.
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.
claimSelf-reported sleep duration data in the UK Biobank study may be subject to reporting inaccuracy and recall bias, as older adults often report longer sleep durations than objective measurements indicate, particularly when sleep quality is poor.
