Objectives The majority of the previous research has focused on the impact of average sleep
parameters on longevity. In this study, we aimed to investigate the associations of day-to-day …

Objective We investigated the factors that predispose or precipitate greater intra-individual
variability (IIV) in sleep. We further examined the potential consequences of IIV to overall …

INTRODUCTION Measuring day‐to‐day sleep variability might reveal unstable sleep‐wake
cycles reflecting neurodegenerative processes. We evaluated the association between …

Sleep variability (eg intra-individual variabilities in sleep duration or sleep timing, social
jetlag, and catch-up sleep) is an important factor impacting health and mortality. However …

Abstract Study Objectives The purpose of this study was to examine the degree of short-term
stability of polysomnographic (PSG) measured sleep parameters and the overall differences …

Laboratory based sleep deprivation studies demonstrate that lack of sleep impairs well-
being and performance ability, but suggest that these effects are mitigated in older adults …

Background Day‐to‐day variability in sleep patterns and eating timing may disrupt circadian
rhythms and has been linked with various adverse cardiometabolic outcomes. However, the …

Objectives Greater sleep disturbances on average are a risk factor for impaired mental
health. Recent research has shown that more intraindividual variability (ie, inconsistency) in …

Video games are a popular form of entertainment. However, there is mixed evidence for the
association between video game usage and poor sleep quality, short sleep duration, or …

Objective To describe components of night-to-night variation in objective measures of sleep.
Methods We conducted a secondary data analysis of consecutive and chronologically …
