Fibromyalgia: the role of sleep in affect and in negative event reactivity and recovery

OBJECTIVE: 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. DESIGN AND MEASURES: 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. RESULTS: 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. CONCLUSIONS: These results lend support to the hypothesis that sleep is a component of allostatic load and has an upstream role in daily functioning.     

Things fall apart. The cultural complex in contemporary times1

These extraordinary months due to COVID-19 and the Black Lives Matter protests, set as they are against a backdrop of the increasingly worrying climate emergency, have brought fear, anxiety and discord across the globe. But we have also experienced a deepening of our understanding of our connectedness, protests against injustice, expressions of social concern and a demand for change. The concept of the cultural complex as developed by Singer & Kimbles (2004) offers a helpful means of connecting the psychology of the individual psyche and the political phenomena of power relations. Using a small example to illustrate how it might operate at a local level, I suggest that a fundamental shift is taking place raising profound levels of anxiety as we move from the known to the unknown. The bipolar nature of these complexes means the extremes are surfacing bringing fears of the very real possibility of more entrenched attacks on democracy from the far right and the hunkering down behind armed borders. But there is also hope that different ways of living together may be developing from the ground up, ways that are rooted in our sense of interdependence – with each other and our planetary home.

The breathing bear with preterm infants: Effects on sleep,respiration, and affect

This study investigated the sleep/wake states, respiration, and affective behaviors of premature infants who were provided à “breathing” bear in the isolette from 33 to 35 weeks conceptional age (CA). The Breathing Bear is à source of rhythmic stimulation that is optional for the infants. Its “breathing” reflects the breathing rate of the individual infant. At 33 weeks CA, 27 premature infants were provided à Breathing Bear (BrBr) and 26 were given à Non-Breathing Bear (N-BrBr). At 35 weeks, interfeed observations for an average of 1.7 hours were made of the babies' states and state-specific behaviors, along with respiration recordings. By 35 weeks, the BrBr babies showed less wakefulness, more quiet sleep, fewer startles in quiet sleep, and less crying than the N-BrBr babies. In addition, they were more likely to smile and N-BrBr babies were more likely to grimace in active sleep. These findings replicate and extend previous reports of effects of the Breathing Bear on neurobehavioral organization. They also suggest that less negative affect is expressed by the BrBr babies; and they point to the importance of future study of preterm infants' affective expressions, both in sleep and in waking.
