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.
Stroke victims who have obstructive sleep apnea die sooner than stroke victims who do not have sleep apnea or who have central sleep apnea, according to Swedish researchers, who will present their findings at the American Thoracic Society’s 2008 International Conference in Toronto on Monday, May 19.
The researchers followed 132 stroke patients over 10 years. Twenty-three of those patients had obstructive sleep apnea; 28 of those patients had central sleep apnea. Those with an obstructive apnea-hypopnea index of 15 or greater were 76 percent more likely to die earlier. Those with a lower apnea-hypopnea index of 10 were also at greater risk of early death.
The recent rise in obesity may be partly due to the reduced amount of time we spend asleep, according to new research from the University of Bristol in the United Kingdom.
Dr. Shahrad Taheri from Bristol University, and colleagues in the United States, examined the role of two key hormones that are involved in regulating appetite — ghrelin and leptin. Ghrelin increases feelings of hunger while leptin acts to suppress appetite.

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.
