Even a good night's sleep doesn't totally compensate for many weeks of sleep loss. And it's the late-night period when the accumulation of sleep loss may be most apparent. Researchers at Brigham and Women's Hospital examined the effect of weeks of insufficient sleep on performance. They scheduled nine healthy volunteers to live for three weeks on a schedule consisting of 43-hour periods in which they were awake for 33 of those hours. That equals about 5.6 hours of sleep for every 24 hours.

You can't sleep. You've tried counting sheep, drinking warm milk, maybe even taking medications like Benadryl or sleeping pills. Maybe next you should try cooling your brain. According to research presented Monday at Sleep 2011 , the annual meeting of the Associated Profession Sleep Societies, cooling the brain and can reduce the amount of time it takes people with insomnia to fall asleep -- and increase the length of time they stay that way. To achieve "frontal cerebral thermal transfer," as the cooling is called, researchers Dr. Eric Nofzinger and Dr. Daniel Buysse of the Sleep Neuroimaging Research Program at the University of Pittsburgh School of Medicine outfitted 24 people -- 12 with insomnia, and 12 without -- with soft plastic caps. The caps had tubes for circulating water at neutral, moderate or maximum "cooling intensity.

My 88-year-old husband was prescribed Ambien for insomnia. After the first dose, he fell while getting up to go to the bathroom, gashed his head and had to go to the emergency room for stitches. A year later, I gave him a half-dose (again prescribed), and within minutes, his legs collapsed on him. I had the hardest time getting him into bed. Ambien? Never again! Your experience reminds us that sleeping pills may pose a serious risk for older people who have to get up at night to go to the bathroom.

For those who struggle with post-traumatic stress disorder, phobias, anxieties and other fearful memories, the bedroom may be the next big battleground. Researchers are finding that sleep may allow us not just to escape our cares temporarily, but to defang some of the fearful memories that hobble those with such anxiety disorders. Two studies published in the past week break new ground in the effort to take the fright out of frightening memories, both of them exploring the opportunity afforded by sleep to do so. They proceed from two relatively recent neuroscientific insights about memories: that they change a little every time they are taken out, revisited and returned to storage; and that sleep is a time when old memories and new experiences alike are processed, prepared and filed into the brain's long-term storage vault.

It can take several days to recover after experiencing a few nights of little sleep, according to a new study. Researchers found that even a catch-up night of 10 hours of sleep may not be enough to restore many people after they have a few nights of bad sleep. The study involved 159 adults who were assigned to sleep a certain number of hours a night. The participants underwent computerized neurobehavioral tests during the day to assess their cognitive function. Their results were compared to see how well they recovered after various amounts of sleep deprivation.
