#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

Short #Sleep Is Associated With Low Bone Mineral Density and #Osteoporosis in the Women’s Health Initiative

.. 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

#Insomnia symptoms and risk of cardiovascular diseases among 0.5 million adults. A 10-year cohort

..Three insomnia symptoms were assessed with self-reported difficulties in initiating or maintaining sleep, early morning awakening, and daytime dysfunction for at least 3 d/wk at baseline ..Cox regressions showed that 3 insomnia symptoms were associated with increased risk of total #CVD, with respective adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of 1.09 (95% CI 1.07–1.11), 1.07 (95% CI 1.05–1.09), and 1.13 (95% CI … Continue reading #Insomnia symptoms and risk of cardiovascular diseases among 0.5 million adults.

Effect of different #nap opportunity durations on short-term maximal performance, attention, feelings, muscle soreness, fatigue, #stress and sleep.

The aim of the present study was to determine the effect of different nap opportunity durations on short-term maximal performance, attention, feelings, muscle soreness, fatigue, stress and sleep. Twenty physically active men (age: 21.1 ± 3.6 years, height: 176.4 ± 5.7 cm, body-mass: 72 ± 10.8 kg) performed the 5-jump and the digit-cancellation (i.e., attention) tests after four randomized nap opportunity conditions: no-nap opportunity (N0), 25 min of nap opportunity (N25), 35 min of nap opportunity … Continue reading Effect of different #nap opportunity durations on short-term maximal performance, attention, feelings, muscle soreness, fatigue, #stress and sleep.

Interplay of Objective #sleep Duration and Cardiovascular and #Cerebrovascular Diseases on Cause‐Specific Mortality

Cardiovascular and cerebrovascular diseases (CBVDs) and cancer are leading causes of death. Short sleep is a potential contributor to health; however, its role in predicting mortality associated with cardiometabolic risk factors (CMRs) and CBVD remains poorly understood.  CMR was defined as stage 2 hypertension and/or type 2 diabetes mellitus on the basis of blood pressure and glucose levels or a report of diagnosis or treatment for these conditions. CBVD was … Continue reading Interplay of Objective #sleep Duration and Cardiovascular and #Cerebrovascular Diseases on Cause‐Specific Mortality
