“…A total of 390 participants met all eligibility criteria and completed all study visits. Note that the sample size here is discrepant from previous publications involving this study (n = 391) (20), as one of the participants who completed the study was recently determined to have been ineligible due to shiftwork. The study was approved by the University of Pittsburgh Institutional Review Board.…”

Objective Evidence suggests a link between positive social relationship perceptions and improved sleep (e.g., quality, efficiency) across the lifespan. Less work has probed the directionality of these relationships. Here, we report findings from the first study to examine bidirectional between- and within- person associations between loneliness and emotional support with daily life measures of sleep. Methods Participants were 389 healthy adults aged 40-64 (61% female) who completed hourly surveys assessing loneliness and perceptions of emotional support over the course of four days. Measures of actigraphy-assessed sleep and nightly sleep quality were also assessed over seven to ten days. Results Individuals with lower average daily loneliness showed higher sleep quality and efficiency than individuals with higher loneliness (r = -0.19, p < .001; r = -0.14, p = .008, respectively), and greater average emotional support was likewise linked with better sleep quality (r = 0.18, p < .001). Controlling for neuroticism attenuated the effects of average loneliness on sleep. Within-person analyses showed unexpected bidirectional effects. Specifically, days in which people felt relatively lonelier were followed by nights with greater sleep efficiency (γ = 1.08, p = .015), and nights when people reported relatively poorer sleep quality were followed by days with greater emotional support (γ = - 0.04, p = .013). These unexpected findings are probed in exploratory analyses. Conclusions Individuals with higher loneliness and lower emotional support report poorer sleep quality and efficiency, on average. Day-to-day fluctuations in perceptions of social relationships may affect the following night’s sleep, and vice versa.

“…Given the heterogeneity of the studies no definitive conclusions can be made, however, the accumulated evidence suggests that sleep duration (specifically short sleep) [46,48,54], sleep fragmentation (frequent awakenings) [43,44,45], a lack of sleep depth (low N3 time) [43,44,58] and increased variability in sleep timing (irregular sleep timing) [50][51][52]57] may be associated with nocturnal BP nondipping in otherwise healthy individuals. The direction of this relationship, however, is unclear (Figure 2).…”

“…In the five studies that did not fully meet the criteria, a lack of confounding factors identified was with the main factor contributing to their lower appraisal. Seven studies assessed sleep using polysomnography (PSG) [42][43][44][45][46][47][48], six used wrist actigraphy [44,45,[48][49][50][51], six used only self-report methods (e.g. sleep diaries and questionnaires) [52][53][54][55][56][57] and one used an EEG headband [58].…”

Objective The current literature investigating nocturnal blood pressure (BP) nondipping has largely focused on clinical populations, however, conditions such as hypertension, obstructive sleep apnoea and insomnia are recognized confounding factors for BP dipping. The exact mechanisms responsible for BP nondipping remain unclear, therefore, there is a need to investigate BP nondipping in healthy individuals to better understand the underlying mechanisms. This review identifies sleep characteristics that may contribute to BP nondipping in healthy individuals. It is anticipated that an understanding of the sleep characteristics that contribute to BP nondipping may inform future sleep-related behavioral interventions to ultimately reducing the burden of cardiovascular disease. Methods The PubMed, Scopus and Web of Science databases were searched for relevant, English language, peer-reviewed publications (from inception to March 2022). The search identified 550 studies. After duplicates were removed, the titles and abstracts of the remaining 306 studies were screened. Of these, 250 studies were excluded leaving 56 studies to test for eligibility. Thirty-nine studies were excluded such that 17 studies fully met the inclusion criteria for the review. Results Findings from this review indicate that short sleep duration, more sleep fragmentation, less sleep depth and increased variability in sleep timing may be associated with BP nondipping in healthy individuals. Conclusion While there is no evidence-based approach for the treatment of nocturnal BP nondipping, it seems promising that addressing one’s sleep health may be an important starting point to reduce the prevalence of BP nondipping and perhaps the progression to cardiovascular disease.

“…There is growing evidence, however, that irregular sleep habits are common in the population and that intraindividual variability in sleep (IIV) could be a key dimension of overall sleep health (8,10). Greater IIV (i.e., irregular sleep patterns) has been associated with adverse health consequences such as risk for cardiovascular disease (11,12), poor metabolic health (13,14), depression (15)(16)(17), worse stress regulation (18), worse cognitive functioning (13), greater daytime sleepiness (19), poorer academic performance (20), and greater mortality (21).…”

Objective We investigated the factors that predispose or precipitate greater intra-individual variability (IIV) in sleep. We further examined the potential consequences of IIV to overall sleep quality and health outcomes, including whether these relationships were found in both self-reported and actigraphy-measured sleep IIV. Methods In Study 1, 699 US adults completed a Sleep Intra-Individual Variability questionnaire and self-reported psychosocial, sleep quality, and health outcomes. In Study 2, 100 university students wore actigraphy and completed psychosocial, sleep, and health surveys at multiple timepoints. Results In cross-sectional analyses that controlled for mean sleep duration, predisposing/precipitating factors to greater IIV were being an under-represented racial/ethnic minority (Study 1: F = 13.95, p < .001; Study 2: F = 7.03, p = .009), having greater stress (Study 2: r values ≥ 0.32, p values ≤ 0.002) or trait vulnerability to stress (Study 1: rs ≥ 0.15, ps < 0.001), and showing poorer time management (Study 1: r = -0.23, p < 0.001; Study 2: rs ≤ -0.26, ps ≤ 0.013). In addition, both studies showed that greater sleep IIV was associated with decreased overall sleep quality, independent of mean sleep duration (Study 1: rs ≥ 0.20, ps < 0.001; Study 2: rs ≥ 0.33, ps ≤ 0.001). Concordance across subjective and objective IIV measures was modest (rs: 0.09-0.35) and similar to concordance observed for subjective-objective mean sleep duration measures. Conclusion Risk for irregular sleep patterns is increased in specific demographic groups and may be precipitated by, or contribute to, higher stress and time management inefficiencies. Irregular sleep may lead to poor sleep quality and adverse health outcomes, independent of mean sleep duration, underscoring the importance of addressing sleep consistency.
