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