Memory And Sleep - Think It Over, Then Sleep On It When it comes to executing items on tomorrow's to-do list, it's best to think it over, then "sleep on it," say psychologists at Washington University in St. Louis. http://www.medicalnewstoday.com/articles/193592.php Brain's Energy Restored During Sleep, Suggests Animal Study In the initial stages of sleep, energy levels increase dramatically in brain regions found to be active during waking hours, according to new research in the June 30 issue of the Journal of Neuroscience. These results suggest that a surge of cellular energy may replenish brain processes needed to function normally while awake. http://www.sciencedaily.com/releases/2010/06/100629170924.htm A Phase 3, Double-Blind, Randomized, Placebo-Controlled Study of Armodafinil for Excessive Sleepiness Associated With Jet Lag Disorder Armodafinil increased wakefulness after eastward travel through 6 time zones. http://www.mayoclinicproceedings.com/content/85/7/630.long The Impact Of Shift Work Induced Chronic Circadian Disruption On IL-6 And TNF-Alpha Immune Responses Shift work induces chronic sleep debt. Our data reveals that chronic sleep debt might not always lead to an activation of the immune system, as we did not observe differences in lymphocyte count or level of IL-6 or TNF-alpha serum concentration between shift workers and day workers. Therefore chronic sleep restriction might be eased by a long-term compensating immune regulation which (in healthy) protects against an overstimulation of proinflammatory immune mechanisms and moderates metabolic changes, as they are known from short-term sleep deprivation or sleep related breathing disorders. http://www.occup-med.com/content/5/1/18 Relations Between Sleep, Fatigue, And Health-Related Quality Of Life In Individuals With Insomnia More severe fatigue is not necessarily related to poorer polysomnography-defined sleep but appears associated with greater impairment in health-related quality of life. Fatigue and health-related quality of life appear to be distinct but interrelated constructs. http://www.jpsychores.com/article/PIIS0022399910002229/abstract?rss=yes |
