Sleep: an important factor in stress-health models

Stress and Health (Impact Factor: 1.04). 08/2010; 26:204-214. DOI: 10.1002/smi.1304

ABSTRACT A growing body of literature supports the notion that psychological stress negatively impacts physical health. In parallel to this programme of stress/health investigations, researchers are demonstrating the deleterious health effects of poor sleep. The current study simultaneously examines the association of both stress and sleep with health. Two hundred and eighteen subjects completed an anonymous survey packet that included stress, sleep and health measures. Psychological stress (as assessed by both life-events and by self-perceived stress), daytime sleepiness and poor sleep quality, but not sleep quantity, were all negatively associated with health. A regression model that integrated both stress measures was a statistically significant predictor of health. Adding the sleep measures to the stress-health model accounted for a statistically significantly greater proportion of the variance in health scores, with the stress + sleep model accounting for 39–56 per cent of the variance in health scores depending on the health measure used. These results suggest that studies of stress and health may benefit from the inclusion of sleep measures and that, from a practical standpoint, poor sleep might be best understood not simply as a sequela of psychological stress but rather as a factor that should be actively addressed as part of the treatment programme.

    ABSTRACT: Background: Flexible work schedules and on-call work are becoming more and more common in working life. However, little is known about the effects of on-call work on health. Methods: Using a daily survey method, 31 employees from an Information Technology Service Organisation filled out a questionnaire four times a week while they were on call and another four times a week while they were not on call. An evaluation of cortisol levels was included. Multilevel analyses were used to evaluate the data. Results: Results showed increases in irritation and negative mood and decreases in social activities, household activities, and low-effort activities. No effects were found concerning the secretion of cortisol. There were no significant differences between those employees who were actually called in to work during the on-call period and those who were not. Conclusions: Flexible work schedules like on-call work have effects on well-being. The mere possibility of being disturbed by calls shows negative consequences, regardless of whether the employees are actually called in or not.

    ABSTRACT: Previous research has emphasized facets of both the organizational environment and individual differences as predictors of work engagement. This study explored sleep hygiene as another important behavioural factor that may be related to work engagement. With a sample of 328 adult workers, we tested a multiple mediator model in which sleep hygiene predicts work engagement through one's appraisals of resource depletion stemming from demands (psychological strain) and general self-regulatory capacity (self-control). Results indicated that individuals who frequently engaged in poor sleep hygiene behaviours had lower self-regulatory capacity, experienced higher subjective depletion and were less engaged at work. Additionally, the path from poor sleep hygiene to decreased work engagement was attributed to perceptions of personal resources that are needed to exert self-regulatory energy at work. This is consistent with current self-regulatory theories suggesting that individuals have a limited amount of resources to allocate to demands and that the depletion of these resources can lead to stress and lower self-regulatory functioning in response to other demands. Specifically, poor sleep hygiene results in the loss of self-regulatory resources needed to be engaged in work tasks by impairing the after-work recovery process. Practical and research implications regarding sleep hygiene interventions for well-being and productivity improvement are discussed. Copyright © 2012 John Wiley & Sons, Ltd.

    ABSTRACT: BACKGROUND: Recent research suggests that poor sleep may be associated with altered stress regulation. PURPOSE: This study aims to examine the associations between prior-night and prior-month sleep measures and affective, cognitive, and physiological responses to a laboratory stressor. METHODS: Ninety-eight (50 % female) young adults completed measures of sleep quality in the context of a laboratory stress study. Measures included positive (PA) and negative affects (NA) and blood pressure (BP) reactivity, as well as change in pre-sleep arousal. RESULTS: Prior-month poor sleep quality and sleep disturbances predicted dampened BP reactivity. Both prior-night and prior-month sleep quality predicted greater decrease in PA. Sleep-associated monitoring predicted NA reactivity and prolonged cognitive and affective activation. Prior-month sleep continuity predicted greater cognitive pre-sleep arousal change, and prior-month sleep quality, daytime dysfunction, and disturbances predicted prolonged cognitive and affective activation. CONCLUSION: Findings suggest that inadequate sleep confers vulnerability to poor cognitive, affective, and physiological responses to stress.
