“…Recent studies in economics found support for a negative association between sleep and return to wages (Gibson & Shrader, ) and productivity (Jin & Ziebarth, ). The estimated economic cost of insufficient sleep is among the highest in the US ($411 billion per year) and, according to one estimate, the US loses an equivalent of about 1.23 million working days per year due to insufficient sleep (Hafner, Stepanek, Taylor, Troxel, & van Stolk, ). Second, with an increasing pace of adoption of LED lights (Pawson & Bader, ), increasing population density (Bennie, Duffy, Davies, Correa‐Cano, & Gaston, ), and longer awake hours (Walch, Cochran, & Forger, ), exposure to light pollution is also increasing at a rapid pace.…”

Objectives: The objective of this study was to test whether light pollution is associated with lower or insufficient sleep. The American Medical Association recently issued a public notice cautioning against the effects of nighttime light on sleep quality and quantity. Light pollution, through the suprachiasmatic nucleus, disrupts circadian rhythm by reducing the secretion of melatonin, a sleep-inducing hormone. Methods: I used 282 403 individual self-reports of sleep hours and insufficient sleep from the 2014 and 2016 metropolitan and micropolitan statistical area (MMSA) Behavioral Risk Factor Surveillance System (BRFSS) and the prevalence of insufficient sleep during 2014 in 2823 US counties from the County Health Rankings. The nighttime artificial light data are from the cloud-free Visible Infrared Imaging Radiometer Suite available from the National Oceanic and Atmospheric Administration in the US. Results: At the MMSA level, for a 10-unit increase in nighttime light (nW/[cm 2 sr]) the estimated decline in sleep was about 5.59 minutes per day and the odds of reporting insufficient sleep (<7 hours) increased by 13.77%. At the county-level, for a 10-unit increase in nighttime light, the prevalence of insufficient sleep increased by 2.19%. Conclusions: Although light pollution was negatively associated with sleep outcomes, the practical effect sizes were small. The small effects suggest that the effects at the population level are negligible, and the effect of nighttime light pollution is more idiosyncratic.

“…It was also forecasted that non-restorative sleep would impact the world economy due to a decrease in workplace productivity. As an example, a reduction between 299 billion and 433 billion dollars is expected for the United States of America by the year 2020 [2].…”

Sleep related disorders can severely disturb the quality of sleep. Among these disorders, obstructive sleep apnea (OSA) is highly prevalent and commonly undiagnosed. Polysomnography is considered to be the gold standard exam for OSA diagnosis. Even though this multi-parametric test provides highly accurate results, it is time consuming, labor-intensive, and expensive. A non-invasive and easy to self-assemble home monitoring device was developed to address these issues. The device can perform the OSA diagnosis at the patient’s home and a specialized technician is not required to supervise the process. An automatic scoring algorithm was developed to examine the blood oxygen saturation signal for a minute-by-minute OSA assessment. It was performed by analyzing statistical and frequency-based features that were fed to a classifier. Afterward, the ratio of the number of minutes classified as OSA to the time in bed in minutes was compared with a threshold for the global (subject-based) OSA diagnosis. The average accuracy, sensitivity, specificity, and area under the receiver operating characteristic curve for the minute-by-minute assessment were, respectively, 88%, 80%, 91%, and 0.86. The subject-based accuracy was 95%. The performance is in the same range as the best state of the art methods for the models based only on the blood oxygen saturation analysis. Therefore, the developed model has the potential to be employed in clinical analysis.

“…[ 5 ] As the world continues moving toward a modern 24/7 society, a significant proportion of the adult population suffers from insufficient sleep. [ 6 ] The Centers for Disease and Prevention in the United States has declared insufficient sleep a “public health problem.” [ 7 ] Therefore, how to correct the decline in endurance caused by SR has attracted more and more attention, and it is urgent to find a way to deal with it.…”

Scope The study investigates the effects of pterostilbene (PTE) on exercise endurance and circadian rhythm in sleep‐restricted (SR) mice. Methods and results The SR model is established by keeping mice awake during the first 8 h of light period for 5 d and PTE (100 mg kg−1 d−1) is given once a day. PTE improves endurance in SR mice by significantly prolonging the exhaustive swimming time and ameliorating exercise fatigue biochemical parameters, including creatine kinase and lactate dehydrogenase. It is observed that PTE effectively regained mitochondrial function by improving mitochondrial swelling and maintaining oxidative phosphorylation system–related genes expression, and inhibited the decrease of mitochondrial biogenesis–related genes expression. Furthermore, PTE restores rhythms of AMP‐activated protein kinase (AMPK) phosphorylation activity, silent information regulator 1 (SIRT1) deacetylation activity, and SIRT1‐mediated peroxisome proliferator‐activated receptor coactivator 1α (PGC‐1α) deacetylation in SR mice. Finally, the results demonstrate that the AMPK/SIRT1/PGC‐1α pathway may be correlated with the relationships between mitochondrial function and circadian rhythms, markedly regulating the expression of skeletal muscle clock genes, circadian locomotor output cycles kaput, and brain and muscle arnt‐like 1. Conclusions PTE ameliorates SR‐induced exercise intolerance associated with circadian misalignment and mitochondrial dysfunction through AMPK/SIRT1/PGC‐1α pathway.
