Few women sleep great throughout pregnancy. But a new study shows that poor sleep should be of more concern to doctors and women than is currently recognized because it may be a factor in premature birth. A number of problems can contribute to preterm birth, such as illness during pregnancy, obesity and stress. But the new study, published Tuesday in the journal Sleep, is the first to show a connection between poor sleep and preterm birth. Researchers at the University of Pittsburgh School of Medicine looked at sleep and birth outcomes in 166 pregnant women.

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.

It's not hard to imagine that when our distant ancestors began to band together for protection from predators, they probably slept better too (at least those who were on the inside of the tangle of sleeping bodies). A new study finds that all these years later, the link between sleep, society and survival remains fundamental: When we feel connected, we sleep better -- and very likely are better. The study , published Tuesday in the journal Sleep , finds a direct link between our feelings of social connectedness and the unbroken quality of our sleep.

A powerful aftershock early today sent an already unnerved population rushing into Haiti's streets in panic. The U.S. Geological Survey website said the earthquake had a magnitude of 6.1 and was centered 36 miles west-southwest of Port-au-Prince, the capital. The original quake on Jan. 12 was magnitude 7. Haitian radio reported that a number of already damaged buildings collapsed in Wednesday's aftershock. It urged residents of the traumatized city to leave for the provinces.

If you can't quite get that nine-note treble opening to " Fur Elise," just sleep on it. The brain will rehearse, reorganize and nail the sequential motor tasks that help you play piano or type on a keyboard. How that consolidation of memory happens has remained largely a mystery, despite telling evidence that the brain's motor cortex appears to be quite busy during sleep. Now, a team led by Brown University neuroscientists believes it has found the source of the sleeping piano lesson, and it's not where many expected it to be. Neuroscience has been fixated since its founding on why the brain “needs” that peculiar mix of dormancy and random activity known as sleep.

They touch down at another NBA city and check their smartphones to help them adjust to a new time zone while their own bodies struggle. They arrive with bags under their eyes and often depart that city a day later sleepless, jet-lagged, stowing sore joints and heavy legs. During this lockout-shortened NBA season, it's been a grueling routine: 66 games played in 124 days, a pace of one per 1.88 days, or 8.5% faster than a usual season. Every team has played back-to-back-to-back sets and stretches such as nine games in 12 days; the Clippers played 20 games in 31 days in March, a marathon that has not been on the NBA schedule in 45 years.

It's no secret that poor sleep gets in the way of all kinds of good things in life. People who drive on too little sleep -- and there are a lot of us -- are more likely to be in accidents that result in injuries than people who've had enough rest. When we haven't slept well, we make lousy food choices and have trouble metabolizing our food . Staying up too late studying actually hurts high-schoolers' academic performance ...

Extended hours of daylight in the spring lead to later bedtimes for teens, causing them to be sleepier in the morning, researchers reported Tuesday. The conclusion might seem obvious, but the researchers from the Lighting Research Center at Rensselaer Polytechnic Institute in Troy, N.Y., have provided a biological basis for the finding. They conclude that delays in melatonin production by the teens' bodies leads to the later bedtimes. Melatonin is the naturally occurring hormone that regulates sleep on a 24-hour cycle.

Among the many vital roles that sleep plays in our lives, our nightly rest may give us the chance to take out the cerebral trash, says a new study. No, we're not talking about some kind of Ambien-induced sleep-housework. We're talking about the process by which the brain refreshes itself by removing the buildup of mental metabolites such as beta-amyloid and tau -- the byproducts, if you will, of a day's cogitation. Left to fester on the sidewalks of our brains, these byproducts of everyday mental activity can gum up the works in a hurry.

I recall with fondness the years prior to 1989 when I could take for granted my ability to fall asleep quickly and stay asleep for a full eight hours. After a car accident and subsequent surgeries, however, insomnia and its shiftless cousin, fatigue, settled in for an unwelcome stay -- that is, until recently. I had talked with my doctor over the years about this problem. He offered me sleeping medications -- Ambien, Lunesta, Rozerem, Sonata -- but I happen to be one of those unlucky people who is highly sensitive to most kinds of meds, and these were no exception.
