Study from pub med about sleep and fibromyalgia

Study of the role of sleep with Fibro
The role of sleep in affect and in negative event reactivity and recovery.Hamilton NA, Affleck G, Tennen H, Karlson C, Luxton D, Preacher KJ, Templin JL.Department of Psychology, University of Kansas.


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. (PsycINFO Database Record (c) 2008 APA, all rights reserved).

A recent small study from France indicates that fibromyalgia my be related to blood flow issues in the areas of the brain that are responsible for pain measurement and emotional response to pain. You can read more at Fibromyalgia May Be All In Your Head

I believe that sleep is an issue with fibromyalgia but I believe that the lack of sleep often begins with blood sugar problems, namely hypoglycemia. Many fibro patients have hypo and are often undiagnosed. When blood sugar drops too low at night your brain begins to panic so to speak due to lack of glucose, its fuel. This can happen without actually causing you to wake up, although there may be times a person actually does wake up, but it doesn't allow your brain to ever reach the deep sleep stage and it can happen many times at night. It also causes an adrenalin reaction. Later after fibromyalgia progresses, the pain can lead to even more interrupted sleep exacerbating the problem. Often when hypoglycemia is treated and blood sugars are stabilized disrupted sleep patterns begin to correct themselves and patients can sleep soundly and wake up refreshed.

Sleep can be a real problem when the body is in pain.There are painkillers which give you relief for some time but when the effect terminates again the pain comes back and sleep is affected.
