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 daylight and views on the sleep and cognitive performance of … 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, and 8% reported long sleep duration. Those with short sleep … 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 2-weeks of actigraphy followed by a 3-night protocol including dim … 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 (SIK) that signals sleep pressure, have low ATP levels despite … 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 did reveal that a sound which is ranked as melodic … Continue reading #Alarm tones, music and their elements: Analysis of reported waking sounds to counteract #sleep inertia

A randomized, double-blind, placebo-controlled trial of blue wavelength light exposure on sleep and recovery of brain structure, function, and cognition following mild traumatic brain injury

Sleep and circadian rhythms are among the most powerful but least understood contributors to cognitive performance and brain health. Here we capitalize on the circadian resetting effect of blue-wavelength light to phase shift the sleep patterns of adult patients (aged 18–48 years) recovering from mild traumatic brain injury (mTBI), with the aim of facilitating recovery of brain structure, connectivity, and cognitive performance.. ..Relative to placebo, … Continue reading A randomized, double-blind, placebo-controlled trial of blue wavelength light exposure on sleep and recovery of brain structure, function, and cognition following mild traumatic brain injury

Nightly #sleep duration, fragmentation, and quality and daily risk of #migraine

..migraine onset on the day immediately following the sleep period (day 0) and the following day (day 1). ..Sleep duration ≤6.5 hours and poor sleep quality were not associated with migraine on day 0 or day 1. Diary-reported low efficiency was associated with 39% higher odds of headache on day 1 (odds ratio [OR] 1.39, 95% confidence interval [CI] 1.06–1.81). Actigraphic-assessed high fragmentation was associated … Continue reading Nightly #sleep duration, fragmentation, and quality and daily risk of #migraine

#Sleep duration, midday napping, and sleep quality and incident #stroke The Dongfeng-Tongji cohort

..Compared with sleeping 7 to <8 hours/night, those reporting longer sleep duration (≥9 hours/night) had a greater risk of total stroke (hazard ratio [HR] 1.23; 95% confidence interval [CI] 1.07–1.41), while shorter sleep (<6 hours/night) had no significant effect on stroke risk. The HR (95% CI) of total stroke was 1.25 (1.03–1.53) for midday napping >90 minutes vs 1–30 minutes. The results were similar for … Continue reading #Sleep duration, midday napping, and sleep quality and incident #stroke The Dongfeng-Tongji cohort

Influence of #sleep problems and co-occurring musculoskeletal pain on long-term prognosis of chronic low #backpain: the HUNT Study

Compared with persons without sleeplessness, persons who often/always experienced sleeplessness had a lower probability of recovery from chronic LBP (RR 0.65, 95% CI 0.57 to 0.74 in women and RR 0.81, 95% CI 0.69 to 0.95 in men). Although there was no clear evidence of statistical interaction between sleeplessness and co-occurring musculoskeletal pain, women and men who often/always experienced sleeplessness and had ≥5 additional chronic pain sites … Continue reading Influence of #sleep problems and co-occurring musculoskeletal pain on long-term prognosis of chronic low #backpain: the HUNT Study

Effects of total #sleep deprivation on procedural placekeeping: More than just lapses of attention

Total sleep deprivation (TSD) impairs attention as well as higher-order cognitive processes. Because attention is a core component of many tasks, it may fully mediate the effect of sleep deprivation on higher-order processes… A large sample of participants (N = 138 contributing data) performed the Psychomotor Vigilance Task and UNRAVEL under rested or sleep-deprived conditions. TSD impaired placekeeping generally and memory maintenance processes specifically, above … Continue reading Effects of total #sleep deprivation on procedural placekeeping: More than just lapses of attention

In adjusted linear regression models, women who reported sleeping 5 hours or less per night had on average 0.012 to 0.018 g/cm2 significantly lower BMD at all four sites compared with women who reported sleeping 7 hours per night (reference). In adjusted multinomial models, women reporting 5 hours or less per night had higher odds of low bone mass and osteoporosis of the hip (odds ratio [OR] = 1.22; … Continue reading Short #Sleep Is Associated With Low Bone Mineral Density and #Osteoporosis in the Women’s Health Initiative

Temperature and #mental health: Evidence from the spectrum of mental health outcomes

This paper characterizes the link between ambient temperatures and a broad set of mental health outcomes. We find that higher temperatures increase emergency department visits for mental illness, suicides, and self-reported days of poor mental health. Specifically, cold temperatures reduce negative mental health outcomes while hot temperatures increase them. Our estimates reveal no evidence of adaptation, instead the temperature relationship is stable across time, baseline … Continue reading Temperature and #mental health: Evidence from the spectrum of mental health outcomes
