The hypothesis is that individuals with objective short sleep simply have more nights of insomnia per week. Data from a randomised controlled trial of Cognitive Behavioural Therapy for Insomnia combined with zolpidem and/or additional maintenance sessions were analysed. Insomnia frequency was derived from pre-treatment sleep diaries, using two definitions: nights with self-reported sleep latency (SL) or wake after sleep onset (WASO) > 30 min, and nights with self-reported sleep duration < 6 h. Objective short sleep was assessed via PSG sleep study, using < 6 h as the threshold. Results showed that objective short sleep was associated with more frequent insomnia when defined as nights with sleep duration < 6 h (8.1 ± 4.2 vs. 5.9 ± 3.7 nights/fortnight for short sleepers vs. normal sleepers, respectively), but not for nights with SL or WASO > 30 min. While insomnia frequency may partially explain objective short sleep, other factors likely influence this phenotype. Further studies are needed to explore the mechanisms underlying objective short sleep insomnia.","PeriodicalId":17057,"journal":{"name":"Journal of Sleep Research","volume":" ","pages":"e70122"},"PeriodicalIF":3.4,"publicationDate":"2025-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144302352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We previously demonstrated that sleep shortly after learning improves gist abstraction in healthy volunteers across a one-year retention interval using a visual version of the Deese-Roediger-McDermott (DRM) paradigm. Here, we investigate the temporal evolution of this effect by testing recognition performance on a similar DRM task immediately after encoding, as well as 1 week and 1 year later. Moreover, we address the role of feature overlap during encoding, using stimulus sets that are either closely related to or more distant from their common prototype. Behavioural data were obtained from N = 16 healthy volunteers in a within-subjects design, where different sets of shapes were learned in separate experimental sessions, followed by consolidation during day-time wakefulness or nocturnal sleep, respectively. Our results indicate high levels of (false) recognition of non-encoded prototypes for all measurement points, including after 1 year. However, in contrast to our previous findings, gist memory was not affected by whether participants slept or stayed awake during the first 12 h after encoding. Comparisons across experiments indicate that the divergent results are due to changes in task demands rendering item and gist memory traces less distinct in the present study. Our results confirm the behavioural persistence of visual gist abstraction across extended intervals. At the same time, they highlight that sleep effects on this process are highly dependent on task demands.","PeriodicalId":17057,"journal":{"name":"Journal of Sleep Research","volume":" ","pages":"e70106"},"PeriodicalIF":3.4,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144258270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the impact of remote work on employees' sleep health has not been elucidated. This study aimed to examine the longitudinal association between the frequency of remote work and sleep problems among workers in Japan. A 2-year cohort study analysed 824 workers (male: 57.7%, aged 20s: 33.6%) from five companies in Japan. Surveys were administered at baseline (FY2021) and follow-up (FY2023). The outcomes were being at risk of insomnia using the Athens Insomnia Scale, self-reported short sleep duration (SSD), and being at risk of insomnia with SSD. Generalised estimating equation models were used to analyse the association between the frequency of remote work and outcomes, adjusting for demographic, occupational and health-related variables. The retention rate for the follow-up survey was 29.0%, and the prevalence of sleep problems increased during the study. A U-shaped pattern was observed at baseline, with full onsite and full remote work being associated with a higher prevalence of being at risk of insomnia. However, this phenomenon disappeared at follow-up. High frequency (> 80% remote work monthly; odds ratio = 0.54 [95% confidence interval: 0.35-0.82]) and full remote work (odds ratio = 0.41 [95% confidence interval: 0.27-0.61]) were significantly associated with being at risk of insomnia with SSD compared with full-time onsite work. Thus, high frequency and full remote work may have beneficial effects on sleep duration by allowing employees greater flexibility in aligning their work schedules. Further research is needed to confirm these findings and investigate the mechanisms underlying these associations.","PeriodicalId":17057,"journal":{"name":"Journal of Sleep Research","volume":" ","pages":"e70101"},"PeriodicalIF":3.4,"publicationDate":"2025-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144248473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examined associations between hair cortisol concentrations and self-reported sleep quality and objectively measured sleep metrics derived using actigraphy. Data were collected from 306 female and 177 male adults, aged 18-79 years. Hair cortisol was analysed from 3-cm proximal hair segments from the head to represent cortisol accumulation over approximately 90 days. Sleep quality measures included Pittsburgh Sleep Quality Index (PSQI) scores and five actigraphy-derived metrics: sleep latency, total sleep time, wake after sleep onset, sleep efficiency and awakening bouts. In the fully adjusted multiple regression model, higher hair cortisol concentrations were associated with poor self-reported sleep quality (i.e., PSQI > 5; p = 0.020), and higher mean PSQI scores (p = 0.027). No significant relationships were observed with actigraphy-derived sleep measures. The findings support hair cortisol as a promising biomarker for evaluating chronic stress that often coincides with self-reported sleep disturbance. The results suggest the importance of aligning time reference periods for biomarker and self-reported outcomes and highlight the need for further research to reconcile discrepancies between subjective and objective sleep measures.","PeriodicalId":17057,"journal":{"name":"Journal of Sleep Research","volume":" ","pages":"e70105"},"PeriodicalIF":3.4,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144234434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we report an updated preferred reporting items for systematic reviews and meta-analysis systematic review and meta-analysis testing the effects of experimental total and partial sleep deprivation on circulating inflammatory markers in healthy adult individuals. PubMed, Scopus, PsycINFO, and CINAHL were searched up to March 2025. Data were analysed using the DerSimonian and Laird random effects approach. Of the 2264 articles retrieved, we included 35 studies reporting on 887 participants. Compared to normal sleep, multiple nights of experimental partial sleep deprivation (sleep duration reduced to ~4.30 h for 3+ nights) were associated with a significant increase of interleukin-6 [IL-6, k = 5, d = 0.42, [95% CI = 0.11 to 0.73], p < 0.01] and C-reactive protein [CRP, k = 5, d = 0.76, [95% CI = 0.09 to 1.43], p = 0.03] in blood. A single night of total or partial sleep deprivation was not associated with changes in inflammation. Results suggest that the upregulation of inflammatory proteins in blood may only manifest following persistent periods of partial sleep deprivation. Further research will be needed to determine whether sleep recovery strategies (e.g., naps, sleep extension) may restore immune homeostasis. We suggest that experimental partial sleep deprivation for at least 3 nights may elicit peripheral IL-6 and CRP and could therefore serve as a valid procedure to study sleep-related immunopathological processes.","PeriodicalId":17057,"journal":{"name":"Journal of Sleep Research","volume":" ","pages":"e70099"},"PeriodicalIF":3.4,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144234433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cognitively normal older adults (ages 60-85) with symptoms of insomnia underwent PET and overnight polysomnography. Pearson correlations determined the association between sleep variables and the standard uptake values ratio (SUVR) within global cerebral cortex, precuneus, posterior cingulate cortex (PCC), and the medial prefrontal cortex (mPFC). Multivariable stepwise regression was performed for each region of interest with apolipoprotein-ε (APOE) genotype and age as potential covariates.

Forty-three adults (69.3 ± 5.5 years old; 32.6% Aβ elevated; mostly non-Hispanic white and female) were included in analyses. Longer stage 1 was related to greater cortical and mPFC SUVR, greater wake after sleep onset was related to greater cortical, mPFC, and precuneus SUVR, and shorter stage 2 was associated with greater PCC SUVR. Compared to those who were Aβ non-elevated, those who were Aβ elevated had longer stage 1 and shorter stage 2 sleep. Greater sleep fragmentation, longer stage 1 sleep, and shorter stage 2 sleep were associated with greater Aβ burden in various regions of the brain in cognitively normal older adults.

This was a retrospective study of all adults that had undergone a MSLT at St. Michael's Hospital (Toronto, Ontario, Canada) from 1 January 2008 until 31 December 2018. Three groups of persons were considered: active cannabis-only smokers, active tobacco-only smokers and non-active cannabis and tobacco smokers.

We identified a total of 139 individuals undergoing MSLT, of whom 9 (6.5%) were active cannabis-only smokers, 14 (10.0%) were active tobacco-only smokers and 116 (83.4%) were non-smokers. There were non-significant trends among cannabis-only smokers versus non-smokers and tobacco-only smokers towards lower mean sleep onset latency on MSLT (8.1 min vs. 9.2 min and 10.5 min, respectively) and there was a greater proportion of severe sleepiness (33.3% vs. 22.4% and 14.3%, respectively), having at least one REM sleep onset period (55.6% vs. 28.4% and 42.9%, respectively), narcolepsy diagnosis (22.2% vs. 8.6% and 7.1%, respectively), and idiopathic hypersomnia diagnosis (33.3% vs. 30.2% and 14.3%).

Three specific periods in a woman's life-puberty, pregnancy and menopause-seem to be associated with marked gender differences in insomnia prevalence. Puberty is a critical stage for the development of insomnia, with an increase in its prevalence among girls after menarche. During pregnancy and the postpartum period, women also report a rise in insomnia symptoms. Various factors, including hormonal, physiological, relational, emotional and environmental ones, can affect sleep during these sensitive times. Furthermore, the transition to menopause tends to exacerbate gender differences in insomnia prevalence, as it is associated with the emergence of physiological and psychological symptoms (e.g., hot flashes, sleep disturbances and mood changes) that can impair sleep. Thus, biological and psychosocial factors seem to explain gender differences in insomnia prevalence and characteristics throughout the lifespan. Considering this framework, this review aims at summarising and deepening the existing empirical literature on gender differences in sleep physiology, insomnia prevalence and clinical characteristics, and predisposing, precipitating and perpetuating factors for insomnia disorder, in different ages throughout the lifespan. Attention is also given to sexual minority groups, providing a snapshot of sleep difficulties and insomnia symptoms among transgender people. Although the topic is relevant, available literature is still quite scarce. The investigation of gender differences in insomnia disorder could be useful to better understand its prognosis and outline an appropriate and personalised treatment.","PeriodicalId":17057,"journal":{"name":"Journal of Sleep Research","volume":" ","pages":"e70110"},"PeriodicalIF":3.4,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144216133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
