Abstract
The connection between stress and sleep is well established in cross-sectional questionnaire studies and in a few prospective studies. Here, the intention was to study the link between stress and sleep on a day-to-day basis across 42 days. Fifty participants kept a sleep/wake diary across 42 days and responded to daily questions on sleep and stress. The results were analyzed with a mixed model approach using stress during the prior day to predict morning ratings of sleep quality. The results showed that bedtime stress and worries were the main predictors of sleep quality, but that, also, late awakening, short prior sleep, high quality of prior sleep, and good health the prior day predicted higher sleep quality. Stress during the day predicts subsequent sleep quality on a day-to-day basis across 42 days. The observed range of variation in stress/worries was modest, which is why it is suggested that the present data underestimates the impact of stress on subsequent sleep quality.
    • Contrary to expectations, no association was found between inflammatory cytokines and any of the subjective health ratings in women. In previous research the link between inflammation and self-rated health was suggested to be more robust for women compared to men[6,32,37,40,41]. However, only a limited number of studies on self-rated health and inflammation have been stratified for sex and the sample sizes have generally been small with low statistical power and few men have been included[6,42].
    [Show abstract] [Hide abstract] ABSTRACT: Asthma is a chronic inflammatory respiratory disorder associated with reduced lung function and poor quality of life. The condition is also associated with poor self-rated health, a major predictor of objective health trajectories. Of biological correlates to self-rated health, evidence suggests a role for inflammatory cytokines and related sickness behaviours. However, this is mainly based on cross-sectional data, and the relation has not been investigated in patients with chronic inflammatory conditions.

    • A range of studies have indicated that subjective and objective sleep disturbances are associated with stress (Bastien et al., 2004;Reynolds et al., 1992Reynolds et al., , 1993); that stressful events can predict future sleep disturbances (Lallukka et al., 2012;Vahtera et al., 2007); and that pre-sleep stress levels are predictive of subsequent subjective sleep quality (Akerstedt et al., 2012). Whilst the link between stress and sleep is well established, the impact of an anticipated stressor upon sleep is less clear, with the exception of a limited number of studies.
    [Show abstract] [Hide abstract] ABSTRACT: Whilst the association between sleep and stress is well established, few studies have examined the effects of an anticipated stressor upon sleep and relevant physiological markers. The aim of the present study was to examine whether an anticipated stressor in the form of next-day demand affects subjective and objective sleep, and multiple indices of the cortisol awakening response. Subjective and objective sleep and the cortisol awakening response were measured over three consecutive nights in 40 healthy adults in a sleep laboratory. During their second night, participants were informed that they would either be required to complete a series of demanding cognitive tasks, in a competition format, during the next day (anticipation condition; n = 22), or were given no instruction (sedentary condition; n = 18). Sleep was measured subjectively using sleep diaries, objectively using polysomnography, and saliva was measured at awakening, +15, +30, +45 and +60 min each morning, from which cortisol awakening response measurement indices were derived: awakening cortisol levels, the mean increase in cortisol levels and total cortisol secretion. There were no between-group differences in subjective or objective sleep in the night preceding the anticipated demand; however, compared with the sedentary condition, those in the anticipation group displayed a larger mean increase in cortisol levels, representing the cortisol awakening response magnitude, on the morning of the anticipated demand. Overall, the results suggest that whilst anticipated stress affected the subsequent cortisol awakening response, subjective and objective sleep remained undisturbed. It is possible that the timing of an anticipated stressor, rather than its expected duration, may influence subsequent sleep disruption.

    • Active inhibition of one's thoughts and feelings may increase arousal, worry, and intrusive thoughts that may lead to increased experiences of stress over time [35]. Negative affect is often a consequence of stress and has been associated with poor physical health [36], including poor sleep outcomes [29], more frequent asthma symptoms and worse pulmonary functioning in youth with asthma [37] . Research with adolescents has shown that daily negative affect strongly predicts sleep disruptions and sleep quality [38,39].
    [Show abstract] [Hide abstract] ABSTRACT: Among older children and adolescents, keeping secrets from parents is consistently associated with lower levels of psychological well-being. Further, concealing one's thoughts and emotions has been associated with poor physical health outcomes in adults. However, it remains an open question whether secret-keeping is associated with poorer health and health-related behaviors (such as sleep) among youth and, if those hypothesized links exist, what the psychological mechanisms might be. We investigated the associations among youth secrecy towards parents, daily asthma symptoms and daily sleep behaviors in a sample of low-income youth with asthma aged 10–17 and tested negative affect as a possible mediator of these associations.

    • Second, we assessed general or trait worry, not nighttime sleep-related worry. Research documents that nighttime sleep-related worry and stress near bedtime are associated with sleep impairment (Åkerstedt et al., 2012; Lancee, Eisma, van Zantem, & Topper, 2015), which in turn, may increase presleep arousal (Yeh, Wung, & Lin, 2015) that persists into and disrupts sleep. Based on this pattern, it is possible that African Americans engage both in reflection on previous discrimination experiences and worry about future experiences of discrimination at the end of the day.
    [Show abstract] [Hide abstract] ABSTRACT: Background: African Americans experience more problematic and disordered sleep than White Americans. Racial discrimination has been implicated in this disparity. However, the mechanisms by which discrimination disrupts sleep are unclear. It has been theorized that Perseverative Cognition (PC), characterized by recurrent patterns of reflective (i.e., rumination) and anticipatory (i.e., worry) negative thinking about personally relevant stressors, may reflect the functional mechanism linking discrimination to sleep. The present study is the first to empirically examine the dual components of PC as a candidate functional mechanism in the association between racial discrimination and subjective sleep quality. Participants: Sixty-eight self-identified African American college students (55.9% female; Mage = 20.18, SD = 2.93) were recruited at a large predominantly white public university in the Midwest. Methods: The participants completed the Perceived Ethnic Discrimination Questionnaire (PEDQ), Pittsburgh Sleep Quality Index (PSQI), Penn State Worry Questionnaire (PSWQ), and Ruminative Responses Scale (RRS). Results: After adjusting for age, gender, and social class, results revealed a significant indirect effect of racial discrimination (RD) on subjective sleep quality through rumination, 95% CI [.008, .125], but not worry. RD was positively associated with rumination, b =.50, SE =.16, p = .003, and rumination, in turn, was positively associated with poorer sleep quality, b = .09, SE = .04, p = .012. Conclusions: As both RD and poor sleep quality have been directly linked to heart disease, diabetes, depression, and a number of other maladies, our findings suggest that RD, sleep, and coping strategies (e.g., rumination) employed to manage RD experiences may be important targets for addressing racial disparities in health.

    • In addition to this line of research that focused on job stressors, other studies looked at psychological strain as a predictor of poor sleep. Åkerstedt, Orsini, et al. (2012) collected diary data on sleep parameters, stress during the day, and worries at bedtime from a sample of 50 adults (70% employed) over a period of 42 days. In univariate analyses, both average stress during the day and worries at bedtime predicted poor sleep quality during the following night.

    • Secondly, this study focused mainly on burnout as the explanatory variable in the relationship between commuting stress and work outcomes. However, commuting stress may impede other vital processes such as recovery and sleep, which may in turn influence employee well-being (see e.g., Åkerstedt et al., 2012; Van Hooff, 2015). In addition, the alpha coefficient for job satisfaction in the present study was quite low (.62), which may partly account for the nonsignificant relations reported earlier.
    [Show abstract] [Hide abstract] ABSTRACT: This study uses structural equation modelling to test a model that posits that commuting stress would have direct and indirect effects (through burnout) on employee job satisfaction and turnover intention. Based on a sample (N = 336) of employees from diverse occupations in Ghana, the results partly supported the authors’ hypothesized model. Commuting stress was positively related to burnout and turnover intention but had no direct relationship with job satisfaction. In addition, commuting stress was indirectly related to job satisfaction and turnover intention via burnout. These results were found to be invariant for men and women. Implications of the findings for theory and practice are discussed.
