The study found that the Athens Insomnia Scale score after the intervention was significantly lower in the Warm group compared to the Sham group. Additionally, participants in the warm condition showed a decrease in subjective sleep onset latency, better restorative sleep, and improved subjective anxiety before bedtime. A significant reduction in wake after sleep onset was observed in the Warm group at 4 weeks, and this decrease was significantly associated with the degree of improvement in subjective anxiety before bedtime. Furthermore, regular periocular skin warming before bedtime decreased sleep reactivity and improved well-being.

In practice, mental health professionals providing CBT-I lack consensus on whether or not to tolerate short naps during the CBT-I period for requesting patients. In this pilot study, we examined the effects of authorised napping on CBT-I efficiency in patients with insomnia (a napping group was compared with a matched non-napping group, n = 108).

Adult-onset diseases may be linked to early life environmental conditions. The brain regions involved have not yet been identified but, among other areas, the hippocampus is likely to be permanently modulated by early life stress. This structure is involved in the regulation of the activity of the hypothalamic–pituitary–adrenal (HPA) axis, the primary component of stress response. A growing body of evidence suggests that perinatal stress exposure leads to diseases in adult life associated to a hyperactivation of the HPA axis, possibly through an epigenetic programming of the hippocampus, a key structure in the coordination of the hormonal stress response. The persistent hyperactivation of the HPA axis has several consequences also on wake–sleep bahavior, since its mediators acts as wake-promoting molecules. There is a bidirectional relationship between stress and sleep: stress inducing factors may alter sleep–wake architecture and sleep impairment may deeply impact several biological pathways, including stress responses and, eventually, quality of life. However, a new aspect is emerging: the moment of life in which stress is acting should be considered as a relevant factor in mediating the effects of this bidirectional relationship. Here, data from animal studies are collected and presented in order to demonstrate that perinatal stress exposure has long-term effects on sleep phenotype during adulthood. Moreover, the hypothesis that maternal sleep loss during pregnancy can be considered as a prenatal stress factors with the potential to program wake–sleep behaviour, leading to sleep disturbances in adulthood, will be considered. Animal studies produce compelling evidence that: (1) perinatal stress may lead, possibly through epigenetic mechanisms, to health problems in adults, including sleep derangements; (2) sleep loss during pregnancy may be responsible for long-term negative outcomes, including wake–sleep disorders. In conclusion, stress exposure during pregnancy should be considered a big issue not only for mothers but also for children's health in the long-term. Thus, preserving mothers' mental health during pregnancy should be a worldwide priority.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Conflict of Interest&lt;/b&gt;: No.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Session:&lt;/b&gt; Symposium—What can we learn about sleep from aperiodic neural activity?&lt;/p&gt;&lt;p&gt;&lt;b&gt;Presentation:&lt;/b&gt; Fractal cycles of sleep: A new aperiodic activity-based definition of sleep cycles.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Speaker:&lt;/b&gt; Yevgenia Rosenblum, Netherl","PeriodicalId":17057,"journal":{"name":"Journal of Sleep Research","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jsr.14347","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142313416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As one falls asleep, neurotransmitters from sleep–wake regulating neurones work in synergy to control the switching of different sleep states throughout the night. As sleep disorders or underlying neuropathology can manifest as irregular switching, analysing these patterns is crucial in sleep medicine and neuroscience. While hypnograms represent the switching of sleep states well, current analyses of hypnograms often rely on oversimplified temporal descriptive statistics (TDS, e.g., total time spent in a sleep state), which miss the opportunity to study the sleep state switching by overlooking the complex structures of hypnograms. In this paper, we propose analysing sleep hypnograms using a seven‐state continuous‐time Markov model (CTMM). This proposed model leverages the CTMM to depict the time‐varying sleep‐state transitions, and probes three types of insomnia by distinguishing three types of wake states. Fitting the proposed model to data from 2056 ageing adults in the Multi‐Ethnic Study of Atherosclerosis (MESA) Sleep study, we profiled sleep architectures in this population and identified the various associations between the sleep state transitions and demographic factors and subjective sleep questions. Ageing, sex, and race all show distinctive patterns of sleep state transitions. Furthermore, we also found that the perception of insomnia and restless sleep are significantly associated with critical transitions in the sleep architecture. By incorporating three wake states in a continuous‐time Markov model, our proposed method reveals interesting insights into the relationships between objective hypnogram data and subjective sleep quality assessments.","PeriodicalId":17057,"journal":{"name":"Journal of Sleep Research","volume":null,"pages":null},"PeriodicalIF":4.4,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142250910","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}

Delayed onset muscle soreness (DOMS) mimics aspects of chronic pain, predominantly affecting peripheral pain mechanisms, while experimental sleep provocations have been shown to impact central pain mechanisms. This study aimed to combine a DOMS model with total sleep deprivation (TSD) to create a novel model affecting both peripheral and central pain mechanisms. A total of 30 healthy participants attended two sessions (baseline and follow‐up) separated by 24 h of TSD and a home rating after 48 h. Assessments of interleukin 6 (IL‐6) levels, sleep quality, pain catastrophising, affect, and symptoms of depression and anxiety were included in the baseline and follow‐up sessions. Additionally, pressure pain and tolerance thresholds, temporal summation, and conditioned pain modulation (CPM) were assessed using cuff‐pressure algometry in the baseline and follow‐up sessions. DOMS was induced with eccentric calf raises during the baseline session followed by 24 h of TSD. At follow‐up pain tolerance (<jats:italic>p</jats:italic> = 0.012) was significantly reduced, and CPM (<jats:italic>p</jats:italic> = 0.036) was significantly impaired compared to baseline.
