To quantify the association of combined sleep behaviours and genetic susceptibility with the incidence of cardiovascular disease (CVD).Methods and resultsThis study included 385 292 participants initially free of CVD from UK Biobank. We newly created a healthy sleep score according to five sleep factors and defined the low-risk groups as follows: early chronotype, sleep 7–8 h per… Continue reading Sleep patterns, genetic susceptibility, and incident cardiovascular disease: a prospective study of 385 292 UK biobank participants

Light at night in older age is associated with obesity, diabetes, and hypertension
Light at night (LAN) has been associated with negative health consequences and metabolic risk factors. Little is known about the prevalence of LAN in older adults in the U.S. and its association with cardiovascular disease (CVD) risk factors. We tested the hypothesis that LAN in older age is associated with higher prevalence of individual CVD… Continue reading Light at night in older age is associated with obesity, diabetes, and hypertension
Rising temperatures erode human sleep globally
Insufficient sleep is a risk factor for several adverse physical and mental outcomes. A lack of sleep has been associated with reduced cognitive performance, diminished productivity, compromised immune function, adverse cardiovascular outcomes, depression, anger, and suicidal behavior. High ambient temperatures have been associated with reduced subjective sleep quality, but little is known regarding the influence… Continue reading Rising temperatures erode human sleep globally
Poor sleep may undermine people’s attempts to keep weight off
New research being presented at this year’s European Congress on Obesity (ECO) in Maastricht, Netherlands (4-7 May), finds that not getting enough good quality sleep undermines people’s attempts to keep weight off after dieting, and suggests that around two hours of vigorous physical activity per week can help maintain better sleep. The study is by… Continue reading Poor sleep may undermine people’s attempts to keep weight off
Sleep deprivation induces corneal epithelial progenitor cell over-expansion through disruption of redox homeostasis in the tear film
Sleep deficiency, a common public health problem, causes ocular discomfort and affects ocular surface health. However, the underlying mechanism remains unclear. Herein, we identified that short-term sleep deprivation (SD) resulted in hyperproliferation of corneal epithelial progenitor cells (CEPCs) in mice. The expression levels of p63 and Keratin 14, the biomarkers of CEPCs, were upregulated in… Continue reading Sleep deprivation induces corneal epithelial progenitor cell over-expansion through disruption of redox homeostasis in the tear film
Subcortical Neuronal Correlates of Sleep in Neurodegenerative Diseases
Importance Sleep disturbance is common among patients with neurodegenerative diseases. Examining the subcortical neuronal correlates of sleep disturbances is important to understanding the early-stage sleep neurodegenerative phenomena. Objectives To examine the correlation between the number of important subcortical wake-promoting neurons and clinical sleep phenotypes in patients with Alzheimer disease (AD) or progressive supranuclear palsy (PSP).… Continue reading Subcortical Neuronal Correlates of Sleep in Neurodegenerative Diseases
Light exposure during sleep impairs cardiometabolic function
SignificanceAmbient nighttime light exposure is implicated as a risk factor for adverse health outcomes, including cardiometabolic disease. However, the effects of nighttime light exposure during sleep on cardiometabolic outcomes and the related mechanisms are unclear. This laboratory study shows that, in healthy adults, one night of moderate (100 lx) light exposure during sleep increases nighttime… Continue reading Light exposure during sleep impairs cardiometabolic function
Trends in Use of Melatonin Supplements Among US Adults, 1999-2018
Exogenous supplementation of melatonin, one of the key hormones governing circadian rhythm , is indicated for treatment of circadian rhythm sleep disorders1 and, despite insufficient evidence,2 is widely used as an over-the-counter sleep aid. Evidence of antioxidant and anti-inflammatory properties of melatonin3 has prompted investigation of its therapeutic value in multiple diseases.4 Although melatonin is… Continue reading Trends in Use of Melatonin Supplements Among US Adults, 1999-2018
Impact of changing school start times on parent sleep
To examine the impact of changing school start times on sleep in parents of students in elementary, middle, and high school. MethodsAnnual surveys were completed by parents of K-12 students (n = 8190-10,592 per year) before (pre-change) and for 2 years (post-change, follow-up) after implementation of new school start times (elementary school [ES]: 60 minutes… Continue reading Impact of changing school start times on parent sleep
