Burning the candle at both ends for a week may take an even bigger toll than you thought. Researchers at the University of Wisconsin-Madison have found that five nights of restricted sleep – four hours a night — affect the brain in a way similar to that seen after acute total sleep deprivation.
Study is the first experiment to systematically examine the relationship of the duration of sleep dose to the recovery of neurobehavioral deficits from sustained sleep restriction.
A study in the Aug. 1 issue of the journal Sleep suggests that a dose of extra sleep on the weekend may be good medicine for adults who repeatedly stay up too late or wake up too early during the work week.
Research shows sleep deprivation leads to changes in the levels of key proteins that facilitate events involved in the underlying pathology of migraine headaches.
Disruption of two genes that control circadian rhythms can lead to diabetes, a researcher at UT Southwestern Medical Center has found in an animal study. Mice with defective copies of the genes, called CLOCK and BMAL1, develop abnormalities in pancreatic cells that eventually render the cells unable to release sufficient amounts of insulin. Tweet
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.
People who sleep after processing and storing a memory carry out their intentions much better than people who try to execute their plan before getting to sleep.
Adults with sleep apnea often have more heart trouble than those who sleep soundly, research from the American Heart Association finds.
Some 19 percent of soldiers returning from Iraq have migraine and migraine is suspected in another 17 percent. While prevalence of migraine among the U.S. military is well documented, little is known about sleep quality in soldiers with chronic headaches including post-traumatic headache and migraine. Tweet
Bright light therapy has significant effects on sleep disturbances associated with combat-related post-traumatic stress disorder, according to research presented at SLEEP 2010, the 24th annual meeting of the Associated Professional Sleep Societies.
Severe obstructive sleep apnea (OSA) raised the risk of heart failure for middle-aged and older men — and significantly raised the risk of coronary heart disease in men up to age 70

As of May 2, 2009 at 9:47 p.m. (-0500) (ET), the U.S. population
was 306,340,710. Sleep researchers estimate approximately seven percent
of the population suffers from obstructive sleep apnea. Using that
estimate, there are potentially 21,443,850 apneics in the U.S.

As of May 2, 2009 at 9:47 p.m. (-0500) (ET), the world population
was 6,777,286,604. Sleep researchers estimate approximately seven percent
of the population suffers from obstructive sleep apnea. Using that
estimate, there are potentially 474,410,062 apneics in the world.
