Chronic insomnia is associated with subjective daytime cognitive dysfunction, but objective corroborative data are often lacking. In this study, we use Perceptual Load Theory to objectively assess distractibility in participants with insomnia (N = 23) compared with age- and sex-matched controls (N = 23). Following overnight supervised sleep observa...

The study had two objectives: (a) to assess the prevalence of sleep-related habitability concerns in the berthing compartments of U.S. Navy surface ships and (b) to assess whether habitability issues in berthing compartments affected the sleep and well-being of crew members. The importance of habitability for human well-being is recognized. Little ...

To determine the day-to-day and longer-term longitudinal associations between daytime physical activity and night-time sleep. We used data from a 2-year longitudinal study which included three time points (i.e. baseline, year 1, and year 2). Participants were recruited from primary schools and included 1059 children (50% girls) with a mean age of 8...

Sleep is an emergent, multi-dimensional risk factor for diabetes. Sleep duration, timing, quality, and insomnia have been associated with diabetes risk and glycemic biomarkers, but the role of sleep regularity in the development of metabolic disorders is less clear. We analyzed data from 2107 adults, aged 19-64 years, from the Sueño ancillary study...

Sleep behaviors are related to brain structure and function, but the impact of long-term changes in sleep timing on brain health has not been clearly addressed. The purpose of this study was to examine the association of longitudinal changes in sleep timing from middle to late-life with gray matter volume (GMV), an important marker of brain aging. ...

Experimental sleep restriction and deprivation lead to risky decision-making. Further, in naturalistic settings, short sleep duration and poor sleep quality have been linked to real-world high-risk behaviors (HRB), such as reckless driving or substance use. Military populations, in general, tend to sleep less and have poorer sleep quality than nonm...

This quantitative study investigated self-reported sleep, mental health and trauma related nocturnal behaviours among South Sudanese Australians (SSA), examined sex differences in their responses, and sought to determine risk factors for insomnia in this population. Comparisons were also made to a general Australian (AUS) sample of 1,512 respondent...

To compare sleep parameters produced by the Fitbit Charge 3 (Fitbit) and Actigraph GT9X accelerometer (Actigraph) to polysomnography in children and adolescents. Participants (n = 56, ages 9.2 ± 3.3 years) wore a Fitbit and an Actigraph on their nondominant wrist concurrently with polysomnography during an overnight observation at a children's slee...

To the best of our knowledge, there has not as yet been any study on the effects of the COVID-19 pandemic on patients with narcolepsy, in particular, in relation to its impact on sleep schedules, symptoms, the need for medication, work, income, and quality of life. This study therefore aimed to explore these factors and their possible influence on ...
