Investigating adiposity in childhood and adulthood on later life sleep health: a lifecourse Mendelian randomization study

This study uses Mendelian randomization to examine the lifecourse effects of childhood and adulthood adiposity on sleep health outcomes, finding that adult adiposity is a risk factor for insomnia while childhood adiposity may have protective effects when maintained in adulthood.

When sleep reports diverge from physiology: correlates of sleep discrepancy in a health population

The paper examines sleep discrepancy between self-reports and objective measurements in a healthy population, finding that questionnaires are less accurate than daily diaries, and sleep discrepancy is influenced by non-pathological factors.

Association of Sleep with Anxiety in Chinese Empty-Nest Older Adults: The Mediating Roles of Physical Exercise and Social Participation

This study examines the relationship between sleep and anxiety in Chinese empty-nest older adults, finding that poor sleep quality and short sleep duration are independent risk factors, with physical exercise and social participation mediating these associations.

Recent lifestyle change impacts sleep and circadian rhythms among the Indigenous peoples of Peninsular Malaysia

This study examines how lifestyle changes in Indigenous Orang Asli communities in Malaysia affect sleep patterns and circadian rhythms, finding delayed timing and shorter duration with improved quality.

Sleep complaints in alexithymia reflect non-specific negative affectivity

The paper investigates whether alexithymia's association with poor sleep quality reflects physiological changes, specific perception issues, or non-specific negative affectivity, finding the latter.

Beyond Aging, Sex and Insomnia Disorder Shape NREM Brain Oscillations

This study examines how sex and insomnia affect NREM brain oscillations beyond aging, finding sex-specific differences in sleep markers that may explain higher insomnia prevalence in females.

Night-to-night sleep EEG variability over one year

This study examines night-to-night variability in sleep patterns using EEG data over one year, finding that macrostructural patterns are relatively stable while temporal alignment varies significantly.

Additive Effects of Sleep Loss, Psychological Distress and Physical Inactivity on Cognitive Failures in Young Adults

This study examines how sleep loss, psychological distress, and physical inactivity independently and cumulatively affect cognitive failures in young adults, finding additive effects rather than compensatory ones.

Associations between habitual light exposure-related behaviors and sleep timing and sleep complaints in an international community sample

This study examines how habitual light exposure-related behaviors affect sleep timing and complaints in a large international sample, finding that outdoor time and device use in bed have significant impacts.

A Systematic Review and Meta-Analysis of Biological Sex Differences in Sleep Spindles and Slow Wave Activity in Adults with and without Insomnia

This paper reviews and meta-analyzes studies on sex differences in sleep spindles and slow wave activity in adults with and without insomnia, finding sex-based variations in spindle density and power but limited interaction effects.

Rare Coding Variants Reveal Distinct Genetic Architectures Across Multidimensional Sleep Phenotypes

The paper identifies 260 genes associated with sleep phenotypes using rare coding variants from large-scale sequencing data, revealing distinct genetic architectures and biological mechanisms across different sleep measurements.

Whos been sleeping in my bedroom? Sleep and cardiorespiratory physiology when co-sleeping with a dog, cat, or child

This study examines the effects of co-sleeping with dogs, cats, or children on sleep, cardiorespiratory physiology, and next-day activity in adults, finding modest physiological benefits and mixed sleep outcomes.

Music facilitates sleep initiation in adults with sleep-onset insomnia: The role of neural synchronization

This study shows that music helps adults with sleep-onset insomnia fall asleep faster, but neural synchronization to the beat of the music is not the main reason for this effect.

Whole-night gentle rocking improves sleep in poor sleepers with insomnia complaints.

This study shows that whole-night gentle rocking improves sleep quality and efficiency in individuals with insomnia complaints.

A Grid-Search Framework for Dataset-Specific Calibration of Actigraphy Sleep Detection Algorithms

This paper presents a grid-search framework for calibrating actigraphy sleep detection algorithms, showing it can replace manual tuning with improved reproducibility and small performance gains.

Sleep initiation difficulties involve weaker neural and physiological sleep transitions, particularly in children with neurodevelopmental conditions

The paper examines sleep initiation in children with neurodevelopmental conditions, finding weaker neural and physiological transitions linked to longer sleep onset latencies.

No Evidence for Seasonal Variations in Fatigue, Sleepiness, and Insomnia Symptoms: Spring Fatigue is a Cultural Phenomenon rather than a Seasonal Syndrome

The study finds no seasonal variation in fatigue, sleepiness, or insomnia symptoms, suggesting spring fatigue is a cultural phenomenon rather than a biological syndrome.

Neurocognitive deficits in controlling aversive memory among insomnia disorders

This study investigates memory control impairments in insomnia disorder, finding reduced suppression-induced forgetting and altered electrophysiological responses during memory suppression tasks.

Insomnia-Related Metabolomic Profiles Reflect Antioxidant Deficits and Relate to Cognitive Decline Through a Metabolic Risk Score in HCHS/SOL

This study identifies metabolites linked to insomnia symptoms and develops risk scores predicting cognitive decline in Hispanic/Latino adults.

Can we predict sleep health based on brain features? A large-scale machine learning study using UK Biobank

This study uses machine learning on UK Biobank data to predict sleep health traits from brain imaging, finding limited predictive power despite extensive model optimization.

The effect of sex on sleep EEG in typical and altered neurodevelopment

The paper examines sex differences in sleep EEG patterns among children with and without neurodevelopmental disorders, finding significant sex-based variations in sleep features but not in brain age predictions.

Sex- and Depression-specific Effects of Non-pathogenic CAG Repeats in HTT, ATXN3 and CACNA1A on Sleep

This study examines how non-pathogenic CAG repeats in HTT, ATXN3, and CACNA1A genes affect sleep outcomes, finding sex- and depression-specific associations.
