A study in the Feb. 15 issue of the Journal of Clinical Sleep Medicine shows that the use of sleep or napping to relieve chronic pain caused by tension-type headaches could have the unwanted effect of decreasing the homeostatic drive for sleep, leading to reduced ability to initiate and maintain sleep at night.
Use of sleep as a coping mechanism for pain over time could lead to the development of poor sleep hygiene and serve as a perpetuating factor for chronic insomnia.
Group comparisons on triggers of headache indicate that a significantly greater proportion of the headache group relative to the control group (58 versus 18 percent) reported sleep problems as a trigger of headaches, and women in the headache group reported a significantly higher rating of pain interfering with sleep. Eighty-one percent of women who suffer from tension-type headaches reported going to sleep as a way of managing their headaches; this method was also rated as the most effective self-management strategy for pain.
Principal investigator and lead author, Jason C. Ong, PhD, assistant professor of behavioral sciences at Rush University Medical Center, said the extent to which headache sufferers rated sleep as being an effective method for coping with pain was somewhat surprising
"Insomnia is a common complaint among headache sufferers. While napping may relieve pain, it may also result in poor sleep hygiene, thus triggering sleep disturbance or perpetuating an insomnia episode," said Ong.
A high proportion of both the headache and control groups (97 and 70 percent) reported stress as a trigger of headaches. No significant differences were found between the groups on use of medication to relieve headaches.
A total of 65 women were recruited from undergraduate psychology courses at a university located in the southeastern U.S.; 32 participants who were confirmed to have tension-type headaches, as classified by the International Headache Society System, were placed in a headache group, and 33 were classified as controls who experience minimal pain. The average age of members of the headache group was 21.9 years, while the average age of the control group was 18.9 years.
The average time since the first headache of any type was 9.4 years for participants in the headache group, with an average of 8.11 headache days per month. Participants reported an average of 12.2 tension-type headaches over the past year, and 2.1 tension-type headaches in the past month, with a median duration of 2.0 hours. The average tension-type headache intensity rating using a 0-to-10 scale was 5.6. Six participants in the headache group also met criteria for migraine disorder.
Secondary analyses were conducted on self-report data from participants who completed a psychophysiologic assessment investigating the pattern of physiologic, affective and behavioral responses to a picture-viewing task. All participants completed a research questionnaire packet that included measures pertaining to pain history and pain coping strategies. Electromyographic (EMG) activity, self-reported affect and self-reported oral motor behaviors were also analyzed.
The authors conclude that the assessment of daytime napping behaviors among individuals who report insomnia and headaches may be important for developing behavioral sleep interventions. They also note that clinicians should be aware of the challenges of managing pain without causing sleep disturbances.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
