Sleep is beneficial for learning. However, it remains unclear whether learning is facilitated by non-rapid eye movement (NREM) sleep or by REM sleep, whether it results from plasticity increases or stabilization, and whether facilitation results from learning-specific processing. Here, we trained volunteers on a visual task and measured the excitatory and inhibitory (E/I) balance in… Continue reading Complementary contributions of non-REM and #REM sleep to visual #learning

Risk factors of excessive daytime #sleepiness in a prospective population‐based cohort
Although excessive daytime sleepiness is commonly evaluated in clinical and research settings using the Epworth Sleepiness Scale, few studies have assessed the factors associated with its incidence in the general population. We prospectively investigated the predictors of incident and persistent excessive daytime sleepiness in 2,751 subjects (46.1% men, mean age 56.0 ± 9.8 years) from… Continue reading Risk factors of excessive daytime #sleepiness in a prospective population‐based cohort
#Sleep patterns and #insomnia in a large population‐based study of middle‐aged and older adults: The Tromsø study 2015–2016
Epidemiological studies assessing adult sleep duration have yielded inconsistent findings and there are still large variations in estimation of insomnia prevalence according to the most recent diagnostic criteria. Our objective was to describe sleep patterns in a large population of middle‐aged and older adults, by employing accurate measures of both sleep duration and insomnia. Data… Continue reading #Sleep patterns and #insomnia in a large population‐based study of middle‐aged and older adults: The Tromsø study 2015–2016
Association of Rapid Eye Movement #Sleep With Mortality in Middle-aged and Older Adults
Rapid eye movement (#REM) sleep has been linked with health outcomes, but little is known about the relationship between REM sleep and mortality.. ..The MrOS cohort included 2675 individuals (2675 men [100%]; mean [SD] age, 76.3 [5.5] years) and was followed up for a median (interquartile range) of 12.1 (7.8-13.2) years. The WSC cohort included 1386… Continue reading Association of Rapid Eye Movement #Sleep With Mortality in Middle-aged and Older Adults
The Impact of Optimized Daylight and Views on the Sleep Duration and Cognitive Performance of Office Workers
A growing awareness has recently emerged on the health benefits of exposure to daylight and views. Daylight exposure is linked to circadian rhythm regulation, which can have significant impacts on sleep quality and cognitive function. Views of nature have also been shown to impact emotional affect and performance. This study explores the impact of optimized… Continue reading The Impact of Optimized Daylight and Views on the Sleep Duration and Cognitive Performance of Office Workers
Associations of #sleep duration with patient-reported outcomes and healthcare use in U.S. adults with #asthma
..Asthma was identified by self-report. Habitual hours of sleep duration were categorized as short (≤5), normal (6-8), and long (≥9). Multivariate regression analyses were used to examine the associations between sleep duration and patient-reported outcomes and healthcare use. Results Of the 1389 adults with asthma, 26% reported short sleep duration, 66% reported normal sleep duration,… Continue reading Associations of #sleep duration with patient-reported outcomes and healthcare use in U.S. adults with #asthma
#Circadian rhythm and sleep alterations in older people with lifetime #depression: a case-control study
Depression is common in older people and is associated with underlying brain change increasing the risk of dementia. Sleep disturbance is frequently reported by those with lifetime depression, however whether circadian misalignment also exists is unclear. We aimed to examine circadian rhythms and sleep associations in older patients with and without lifetime depression.. ..Participants underwent… Continue reading #Circadian rhythm and sleep alterations in older people with lifetime #depression: a case-control study
A salt-induced kinase is required for the metabolic regulation of #sleep
Many lines of evidence point to links between sleep regulation and energy homeostasis, but mechanisms underlying these connections are unknown. During Caenorhabditis elegans sleep, energetic stores are allocated to nonneural tasks with a resultant drop in the overall fat stores and energy charge. Mutants lacking KIN-29, the C. elegans homolog of a mammalian Salt-Inducible Kinase… Continue reading A salt-induced kinase is required for the metabolic regulation of #sleep
#Alarm tones, music and their elements: Analysis of reported waking sounds to counteract #sleep inertia
Sleep inertia is a potentially dangerous reduction in human alertness and occurs 0–4 hours after waking. The type of sound people set as their alarm for waking has been shown to reduce the effects of sleep inertia, however, the elemental musical factors that underpin these waking sounds and their relationships remain unclear.. ..However, the analysis… Continue reading #Alarm tones, music and their elements: Analysis of reported waking sounds to counteract #sleep inertia
