Objective Sleep restriction alters daytime cardiac activity, including elevating heart rate (HR) and blood pressure (BP). There is minimal research on the cumulative effects of sleep loss and the response after subsequent recovery sleep on HR and BP. This study examined patterns of HR and BP across baseline, sleep restriction, and recovery conditions using multiple daytime cardiac… Continue reading Recovery #sleep following sleep restriction is insufficient to return elevated daytime heart #rate and systolic blood #pressure to baseline levels

The influence of emotion regulation strategies and sleep quality on depression and anxiety
Chronic stress is a major risk factor for a number of mental health disorders, including depression and pathological anxiety. Adaptive cognitive emotion regulation (CER) strategies (i.e. positively-focused thought processes) can help to prevent psychiatric disturbance when enduring unpleasant and stressful experiences, but little is known about the inter-individual factors that govern their success. Sleep plays an important… Continue reading The influence of emotion regulation strategies and sleep quality on depression and anxiety
Sleep Patterns and the Risk of Acute Stroke: Results from the INTERSTROKE International Case-Control Study
Background and Objectives: Symptoms of sleep disturbance are common, and may represent important modifiable risk factors for stroke. We evaluated the association between a spectrum of sleep disturbance symptoms and risk of acute stroke in an international setting.Methods: INTERSTROKE is an international case-control study of patients presenting with first acute stroke and controls matched by… Continue reading Sleep Patterns and the Risk of Acute Stroke: Results from the INTERSTROKE International Case-Control Study
Influence of poor sleep on cardiovascular disease-free life expectancy: a multi-resource-based population cohort study
The complexity of sleep hinders the formulation of sleep guidelines. Recent studies suggest that different unhealthy sleep characteristics jointly increase the risks for cardiovascular disease (CVD). This study aimed to estimate the differences in CVD-free life expectancy between people with different sleep profiles.MethodsWe included 308,683 middle-aged adults from the UK Biobank among whom 140,181 had… Continue reading Influence of poor sleep on cardiovascular disease-free life expectancy: a multi-resource-based population cohort study
Examining understandability, information quality, and presence of misinformation in popular YouTube videos on sleep compared to expert-led videos
The Internet is a common source of sleep information, but may be subject to commercial bias and misinformation. We compared the understandability, information quality, and presence of misinformation of popular YouTube videos on sleep to videos with credible experts. We identified the most popular YouTube videos on sleep/insomnia and 5 videos from experts. Videos were… Continue reading Examining understandability, information quality, and presence of misinformation in popular YouTube videos on sleep compared to expert-led videos
Race Differences in the Association Between Sleep Medication Use and Risk of Dementia
Abstract: Background:The effect of sleep medications on cognition in older adults is controversial, possibly dependent upon sleep quality, and may differ by race. Objective:To determine the longitudinal association between sleep medication use and incident dementia over 15 years, and to explore whether the association is independent of nighttime sleep disturbances and if it differs by race.… Continue reading Race Differences in the Association Between Sleep Medication Use and Risk of Dementia
Associations of serum zinc, copper, and selenium with sleep disorders in the American adults: Data from NHANES 2011–2016
BackgroundEven though various studies have been conducted to investigate the relationship between trace metals and sleep, few epidemiological studies have evaluated the relationship between trace metals and sleep disorders in American adults.ObjectiveThis study intended to evaluate the associations of serum zinc (Zn), copper (Cu), selenium (Se), Zn/Cu, Zn/Se, and Cu/Se ratios with sleep disorders in… Continue reading Associations of serum zinc, copper, and selenium with sleep disorders in the American adults: Data from NHANES 2011–2016
Reported sleep duration reveals segmentation of the adult life-course into three phases
Classically the human life-course is characterized by youth, middle age and old age. A wide range of biological, health and cognitive functions vary across this life-course. Here, using reported sleep duration from 730,187 participants across 63 countries, we find three distinct phases in the adult human life-course: early adulthood (19-33yrs), mid-adulthood (34-53yrs), and late adulthood… Continue reading Reported sleep duration reveals segmentation of the adult life-course into three phases
Associations of sleep timing and time in bed with dementia and cognitive decline among Chinese older adults: A cohort study
Background: The longitudinal associations of sleep timing and time in bed (TIB) with dementia and cognitive decline in older adults are unclear. Methods: This population-based cohort study used data from 1982 participants who were aged ≥60 years, free of dementia, and living in rural communities in western Shandong, China. At the baseline (2014) and follow-up… Continue reading Associations of sleep timing and time in bed with dementia and cognitive decline among Chinese older adults: A cohort study
