Fibromyalgia (FM) syndrome is a chronic pain condition characterized by diffuse muscle pain, increased negative mood, and sleep disturbance. Until recently, sleep disturbance in persons with FM has been modeled as the result of the disease process or its associated pain. The current study examined sleep disturbance (i.e., sleep duration and sleep quality) as a predictor of daily affect, stress reactivity, and stress recovery.
A hybrid of daily diary and ecological momentary assessment methodology was used to evaluate the psychosocial functioning of 89 women with FM. Participants recorded numeric ratings of pain, fatigue, and positive and negative affect 3 times throughout the day for 30 consecutive days. At the end of each day, participants completed daily diary records of positive and negative life events. In addition, participants reported on their sleep duration and sleep quality each morning.
After accounting for the effects of positive events, negative events, and pain on daily affect scores, it was found that sleep duration and quality were prospectively related to affect and fatigue. Furthermore, the effects of inadequate sleep on negative affect were cumulative. In addition, an inadequate amount of sleep prevented affective recovery from days with a high number of negative events.
These results lend support to the hypothesis that sleep is a component of allostatic load and has an upstream role in daily functioning.

    • "Evidence on the influence of sleep on emotional reactivity in everyday life is indirect. For instance, sleep deprivation paradigms may model the effects of acute sleep loss (Hamilton et al., 2008; Talbot, McGlinchey, Kaplan, Dahl, & Harvey, 2010), but may not be informative about the effects of chronically poor sleep quality on emotional functioning. Moreover , results from deprivation studies have been conflicting (sleep deprivation enhances negative emotional reactivity: (Franzen, Buysse, Dahl, Thompson , & Siegle, 2009; Prather, Bogdan, & Hariri, 2013; Rosales-Lagarde et al., 2012); sleep deprivation reduces negative emotional reactivity: (Baran, Pace- Schott, Ericson, & Spencer, 2012; Schwarz et al., 2013).

    ABSTRACT: Disordered sleep has been linked to impaired emotional functioning in healthy and depressed individuals. Little is known, however, about how chronic sleep problems influence emotional reactivity in everyday life. Participants with major or minor unipolar depressive disorder (n = 60) and healthy controls (n = 35) reported on sleep and emotional responses to daily life events using a computerised Experience Sampling Method. We examined whether impaired sleep quality influenced emotional reactivity to daily events, and if this relationship was altered by unipolar mood disorders. Among healthy individuals, sleep difficulties were associated with enhanced negative affect (NA) to unpleasant events and a dulled response to neutral events. However, among mood-disordered persons, sleep difficulties were associated with higher NA across all types of everyday life events. Impaired sleep quality differentially affects daily life emotional reactions as a function of depression.

    • "Sleep quality has been associated with a variety of additional benefits, including lower fatigue (Bliwise, 1992) and lower psychological distress (Shaver & Paulsen, 1993). Good-quality sleep has also been implicated in enhanced physical (Haack & Mullington, 2005) and psychological recovery (Hamilton et al., 2008). Conversely, individuals with chronic pain who report more problematic sleep are more likely to experience significant pain (Finan, Goodin, & Smith, 2013), fatigue (Fishbain, Hall, Risser, & Gonzales, 2009), and poorer physical functioning (L.

    • "Although fatigue and sleep disturbances are not significant enough to differentiate patients with FMS from those with articular and connective tissue disease, subsequent clinical studies determined that the most commonly rated symptoms are unrefreshing sleep, morning stiffness, fatigue, pain, and problems with concentration and memory [4]. It is stated that inadequate sleep has a cumulative effect on negative affects and prevents affective recovery from days with a high number of negative events [5] [6]. Sleep-disordered breathing (SDB) is defined as obstructive breathing episodes occurring exclusively during sleep which is related to relaxation of the pharynx and the consequent increase in upper airway resistance [7].
