		<description><![CDATA[Current sleep remedies risk addiction and memory problems, but a new class of medications may avoid these issues. (UPDATED) A good night’s sleep is hard to get— up to 70 million Americans have disorders that disrupt their nightly slumber and take a toll on their daily activities, according to the latest government data. Among those under age 25, 44% reported falling asleep at least once in the past month because they were sleep deprived. But medications that help us to nod off may not always be safe. Sleeping pills don&#8217;t always lead to a restful night&#8217;s sleep, and studies show they can impair memory or even become habit-forming. But in a study published in Science Translational Medicine, researchers led by Jason Uslaner of Merck found that an experimental agent known as DORA-22 can promote sleep in both rhesus monkeys and rats, without affecting memory or reaction time.  DORA-22 is part of a class of new drugs — one of which the Food and Drug Administration is already considering for approval — known as orexin antagonists. “It’s high quality research,” says Jerome Siegel, professor of psychiatry at University of California Los Angeles, who was not associated with the study. (MORE: Can&#8217;t Sleep? Losing Belly Fat Might Help) The authors compared the sleep-inducing effects of DORA-22 to those of three well-known sleeping pills: diazepam (Valium), zolpidem (Ambien) and eszopiclone (Lunesta), which work by slowing down brain activity. Immediately after giving the animals the drugs, the scientists tested the animals&#8217; memory and reaction time. (While most people take sleeping pills before going to bed, such effects are important to document so researchers, and users, can fully understand how their brains and bodies are affected by the medications in case people don&#8217;t take the drugs as prescribed.) “It’s very enticing because there are some clear results that show [that these drugs] differ from old hypnotic drugs in terms of affecting cognition and memory in two animal species,” says Dr. Emmanuel Mignot, director of the Stanford Center for Sleep Sciences, who wrote a commentary on the<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=healthland.time.com&#038;blog=8684427&#038;post=83934&#038;subd=timewellness&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[Having a drink (or two) is one way to nod off more quickly, but how restful is an alcohol-induced slumber? The latest research, published in Alcoholism: Clinical and Experimental Research, shows that while a nightcap may get you to doze off, you&#8217;re more likely to wake up during the night and may not feel as rested following your sleep. Scientists reviewed 20 studies that included 517 participants who were tested in 38 sleep laboratory experiments. The volunteers drank varying amounts of alcohol, ranging from a low of one to two drinks, a moderate amount of two to four drinks, to a high of four or more drinks. While some experiments examined the results of only one night of drinking, others extended into several consecutive nights. Most of the participants were healthy young adults, and none had drinking problems. (MORE: Sleeping Pills Linked with Early Death) “This review confirms that the immediate and short-term impact of alcohol is to reduce the time it takes to fall asleep,&#8221; lead author of the study Irshaad Ebrahim, director of the London Sleep Center, said in a statement. &#8220;In addition, the higher the dose, the greater the impact on increasing deep sleep.” This helps explain why so many people rely on alcohol to fall asleep, despite warnings from experts that it merely postpones and can worsen insomnia. “The effect of consolidating sleep in the first half of the night is offset by having more disrupted sleep in the second half of the night,” Ebrahim said. That presents a more complicated picture of how alcohol affects sleep, and the trade-off may have implications for understanding how sleep can impact overall health as well. At all doses studied, alcohol increased deep or so-called slow-wave sleep (SWS) during the first part of the night. This type of slumber is associated with healing and regeneration of bones, muscles and other tissues, as well as maintaining a strong immune system. “SWS or deep sleep generally promotes rest and restoration,&#8221; Ebrahim said, cautioning, however, that alcohol increases in this stage can<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=healthland.time.com&#038;blog=8684427&#038;post=79400&#038;subd=timewellness&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[Poor sleeping habits can lead to overeating, but can unhealthy diets keep you up at night? Getting enough sleep and eating right are well-known behaviors for good health. Keeping a balanced diet is one of the best ways to maintain a healthy weight, and those who get 7 to 8 hours of sleep per night tend to have better health overall. Previous studies have linked a lack of sleep to overeating, but less is known about how diet influences sleep patterns. A group of researchers from the Perelman School of Medicine at the University of Pennsylvania investigated how diets correlated with sleep patterns. The researchers studied data from the 2007-2008 National Health and Nutrition Examination Survey (NHANES) involving 4,548 people. They looked at how much sleep the participants reported getting each night, as well as a very detailed report of their daily diet. For the study, very short sleep patterns were defined as less than five hours a night, short sleep was five to six hours a night, standard sleep was 7 to 8 hours, and long sleep was nine or more hours a night. (MORE: Why Sleep Deprivation May Lead To Overeating) It turns out that people in the  different sleep categories also had distinct diet patterns.  Short sleepers consumed the most calories, followed by normal sleepers, then very short sleepers. Long sleepers consumed the least calories. Normal sleepers, however, showed the highest food variety in their diets, and very short sleepers had the least variation in what they ate. A varied diet tends to be a marker for good health since it includes multiple sources of nutrients. Very short sleepers drank less tap water and consumed fewer total carbohydrates and lycopene, found in red and orange-colored fruits and vegetables and high in cancer-fighting antioxidants, than people with other sleep patterns. Short sleepers tended to eat  less vitamin C, tap water and selenium (found in nuts, meat and shellfish) consumption, but more lutein or zeaxanthin, which are found in green, leafy veggies. Long sleep was associated with consuming less theobromine, which<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=healthland.time.com&#038;blog=8684427&#038;post=79698&#038;subd=timewellness&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[It&#8217;s no secret that our ability to remember things dulls as we get older. Now researchers have some clues about why that happens. Scientists at the University of California, Berkeley, found a connection between disrupted sleep — common among the elderly — and memory loss. Their work suggests that as we age, we no longer experience the same deep sleep of our youth and in turn generates fewer of the slow brain waves that are critical for a sharp memory. Slow waves are involved in transferring short-term memories from the hippocampus into long-term memories stored in the prefrontal cortex. According to the authors, normal adults spend a quarter of each night&#8217;s sleep in deep, non-rapid-eye-movement sleep, during which these slow waves are generated. (MORE: Even Brief Exercise Can Improve Memory in Older Adults) The study found that slow waves are created in the middle frontal lobe of the brain and the shrinkage of this region among older adults may be linked to their struggle to experience deep sleep. In older adults, this deteriorating sleep quality interferes with the ability to store memories properly overnight, causing some to be overwritten by new ones. In the latest work, published in the journal Nature Neuroscience, the scientists compared sleep and memory skills among 18 healthy adults in their 20s and 15 healthy elderly adults, primarily in their 70s. All were asked to learn 120 tricky word pairings and were tested on their ability to recall them. The younger group scored about 25% better than the older group. The participants then slept for eight hours while the researchers collected images of their dozing brains using electroencephalograms, or EEGs. Their memories were tested again after their slumber, this time while their brains were imaged using functional and structural Magnetic Resonance Imaging scans. These can detail which areas of the brain are active during specific tasks, and the researchers discovered that the second time around, the younger group scored better by about 55%. (MORE: To Boost Memory, Shut Your Eyes and Relax) The scans also highlighted a strong link between the degree of middle-frontal-lobe-brain<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=healthland.time.com&#038;blog=8684427&#038;post=78920&#038;subd=timewellness&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[The latest research on kids and sleep homes in on the biggest dream-robber. Children are sleeping less, and there&#8217;s no shortage of reasons why: with television, video games and the internet, they are finding it harder to shut down and go to sleep. Over the last century, the time children spend asleep has declined by more than an hour. But which factors are most responsible for keeping kids awake? In a study published in the journal Pediatrics, researchers in New Zealand surveyed more than 2,000 children and young adults aged 5 to 18 about their activities over a 24 hour period. The scientists were interested in learning whether children who went to bed earlier engaged in different activities than those who went to sleep later, and focused on what the children did in the hour and a half before bedtime. The participants listed everything from eating, getting ready for bed, reading, and completing homework, to watching television, playing video games and listening to music. Television was the most common pre-bedtime activity, accounting for 30 of the 90 minutes analyzed on average. And it was also the major reason children stayed up; those who fell asleep later watched 13 more minutes of TV than those who turned in earlier. Watching television also made it harder for the children to fall asleep; the more time they spent in front of the screen, the longer it took them to drift off. “We know that children sleep less than they used to,” says Louise Foley, who was a research fellow at the National Institute for Health Innovation at the University of Auckland when she conducted the study. “The general consensus is that they’re going to bed later, not that they’re getting up earlier.” (MORE: Too Much TV Linked with Thicker, Weaker Kids) Previous studies have pointed to the stimulating effects of television in shortening children&#8217;s nightly slumber, but this analysis is among the first to focus specifically on what children do just before bedtime. Not only is television stimulating for the brain, keeping watchers alert<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=healthland.time.com&#038;blog=8684427&#038;post=77973&#038;subd=timewellness&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[Most of us have experienced it:  that dull, dragging semi-conscious state of deadened awareness and desperate urge to nap that comes from sleep deprivation.  For people with primary hypersomnia, however, this is the way they go through life, constantly feeling only half-awake but never able to get enough good sleep to arise truly refreshed.  Also known as &#8220;Sleeping Beauty Syndrome,&#8221; the condition leaves those with the worst cases languishing in bed in what seems like the opposite of a fairy tale, without a prince&#8217;s kiss to cure them. But a new study, published in Science Translational Medicine, suggests both a possible cause and a potential treatment for the condition, which may ultimately lead to treatments for other sleep disorders.  The origin of primary hypersomnia, which has some genetic components is still unknown, as is the number of people who are affected by it. MORE: Losing Sleep Leads To Gains in Weight One particularly striking form of the disease, Kleine-Levin syndrome, produces such tiredness and sleep-drunkenness that people are unable to attend school or work.  In males, it can include hypersexual behavior, compulsive masturbation, a desire for promiscuous sex or making inappropriate sexual advances, all while in a sleepy, semi-conscious state. In the latest study, researchers led by David Rye of Emory University in Atlanta studied 10 men and 22 women seeking treatment for primary hypersomnia.  In the patients&#8217; spinal fluid, the scientists discovered a previously uncharacterized chemical that stimulates the GABA-A receptor.  This receptor is best known as the site where sleep-inducing drugs like Valium and Xanax have their effects, since activating GABA-A receptors can result in drowsiness. The finding suggested a possible treatment. A drug, known as flumanezil can treat Valium and Xanax overdoses or to reverse the effects of related compounds used in anesthesia. Could it block or reverse the effects of the unknown agent that was activating GABA-A receptors in primary hypersomnia?

		<description><![CDATA[Overexposure to bright light not only keeps you up at night, but animal studies show it may be linked to depressive symptoms and learning problems. That&#8217;s what Samer Hattar, a biology professor at Johns Hopkins University and his team found while studying mice exposed to repeated cycles of bright light. Previous studies hinted at the connection between continued exposure to light and depression in animals, but Hattar also found that the bright lights contributed to poorer learning as well. In the study, published in the journal Nature, the researchers exposed lab mice to 3.5 hours of light followed by 3.5 hours of darkness, which previous work shows does not disrupt sleep cycles in the animals. After two weeks of the light exposure, the mice exhibited symptoms of depression and learning deficits as well as higher levels of the stress hormone cortisol. (MORE: Unplug! Too Much Light at Night May Lead to Depression) “Of course, you can’t ask mice how they feel, but we did see an increase in depression-like behaviors, including a lack of interest in sugar or pleasure seeking, and the study mice moved around far less during some of the tests we did,” said Hattar in a statement. “They also clearly did not learn as quickly, or remember tasks as well. They were not as interested in novel objects as were mice on a regular light-darkness cycle schedule.” At the end of the experiment, the mice were treated with the anti-depressant Prozac, and their normal behaviors returned, which further suggests that their mood and learning issues were linked to depression. According to Hattar and his team, the study results may have relevance to humans since we share light-reactive cells in the eyes called intrinsically photosensitive retinal ganglion cells (ipRGCs) with mice. These cells react to bright light and activate the brain&#8216;s limbic system&#8211;which is responsible for memory and emotion. At night, the system is designed to slow down, but when exposed to light, it becomes active again, essentially working overtime, when it should be resting. &#8220;We still don’t know the exact<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=healthland.time.com&#038;blog=8684427&#038;post=73754&#038;subd=timewellness&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[Poor sleep can lead to weight gain, but now researchers say the relationship works both ways. Studies consistently show that sleep deprivation is linked to obesity and that heavier individuals tend to report more problems getting a good night&#8217;s slumber. Now researchers at Johns Hopkins University School of Medicine report at the 2012 American Heart Association Scientific Sessions in Los Angeles that weight loss, either through diet or a combination of diet and exercise, can lead to better sleep. For six months, the researchers followed 77 overweight or obese individuals with Type 2 diabetes or prediabetes. At the start and end of the study, the participants filled out sleep surveys detailing their sleep problems such as sleep apnea, fatigue, insomnia, restless sleep, excessive sleep and use of sedative. The scientists also measured the volunteers&#8217; body mass index (BMI) to track changes in weight. The participants were then separated into two groups. The first group went on a weight-loss diet with exercise training and the second group simply stuck to a diet program. (MORE: Losing Sleep Leads to Gains in Weight) At the end of the six months, both groups experienced a weight loss of about 6.8 kg on average and a 15% reduction in belly fat. And factoring in a composite score representing their overall sleep health, the authors found both groups also equally boosted their sleep quality by about 20%. “The key ingredient for improved sleep quality from our study was a reduction in overall body fat and, in particular, belly fat, which was true no matter the age or gender of the participants or whether the weight loss came from diet alone or diet plus exercise,” said study author Kerry Stewart, a professor of medicine at John Hopkins in a statement. According to Stewart, belly fat is particularly concerning since it can be metabolically detrimental to health. &#8220;Belly fat is almost like a living organ. It produces proteins that cause inflammation,&#8221; says Stewart. &#8220;When you lose a lot of belly fat in particular, the level of those substances go way down, and the inflammatory response is much less than<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=healthland.time.com&#038;blog=8684427&#038;post=73289&#038;subd=timewellness&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[What does sleep have to do with weight? The latest research finds a link between lack of sleep and hunger. New research published in the journal SLEEP shows that getting more shuteye could lead to less overeating, and that lack of sleep has different influences on hunger in men and women. To take a closer look at the hormonal effects of sleep restriction on hunger, the researchers brought 27 healthy men and women into a sleep lab and manipulated the amount of time they slumbered. In the first condition, the participants slept for four hours a night for three nights in a row. Three weeks later, they were allowed to sleep for nine hours a night for three consecutive nights. (MORE: Why Sleep Deprivation May Lead to Overeating) In order to measure any changes in the body&#8217;s response to the altered sleep patterns, the scientists took blood samples from the volunteers and recorded glucose, insulin, leptin and other hormone levels — all of which are involved in the chain of metabolic signals that lead to hunger. The researchers found that men under restricted sleep conditions experience increases in the hunger-stimulating hormone ghrelin while women in the same conditions did not see heightened ghrelin levels, but instead had reduced levels of the hormone GLP-1, which is produced by the intestinal cells while we eat and tends to suppress appetite. Ghrelin is released by the stomach and pancreatic cells and surge before meals and start to decline after meals. Men in sleep deprived conditions, in other words, were more likely to feel hungry and have larger appetites while women losing shut eye tend to feel less full — both slightly different parts of the same chain of metabolic signals that contribute to hunger. While the metabolic difference seems subtle, after a few sleepless nights, the authors say, both conditions can lead to overeating. And indeed, that&#8217;s what the researchers saw — participants ate about 300 calories more after losing sleep than when they had a full night&#8217;s rest.

		<description><![CDATA[How important is sleep for children? Getting too little could leave them more emotional and impulsive. As a nation, we don’t get enough sleep. And we’re passing along our night-owl habits to members of the next generation, which could leave them with less control over their emotions and more prone to impulsivity, according to the latest study. Lead author Reut Gruber, a psychologist at McGill University, and her colleagues describe in the journal Pediatrics a study in which they either added or deprived healthy children ages 7 to 11 of one hour of sleep a night over five nights. Their goal, says Gruber, was to see if such modest changes in the amount of sleep children get could affect their behavior. The children’s teachers were asked to fill out a 10-item standard questionnaire to assess the children’s attention, impulsivity, irritability and emotional reactivity at the end of the study period. (MORE: Do Snoring Babies Become Troubled Teens?) Compared with their same ratings during an initial five days of unmanipulated sleep — in which the researchers asked parents to allow the children to sleep as they normally would to establish a baseline — those who were deprived of an hour’s sleep had worse scores on behavior measures than those who were allowed to sleep an hour more. (The parents were asked to change their children&#8217;s bed times, and while they were able to put the kids to bed an hour earlier when needed, the youngsters ended up sleeping only about 30 minutes more.) In terms of how emotionally reactive, or sensitive, and how attentive the children were, teachers rated the sleep-restricted students on average 4 points higher than their baseline, meaning they showed more irritability, frustration and had more problems paying attention. In contrast, the children who slept more showed an average 3-point drop in these problems. “Nobody became a genius, and nobody became crazy,” says Gruber, “but the findings show that in children small changes can make a big difference, and that is why this is meaningful.” (MORE: A History<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=healthland.time.com&#038;blog=8684427&#038;post=71449&#038;subd=timewellness&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[People who work irregular schedules or work outside of normal daytime hours are at higher risk of heart attack, stroke and other coronary events, according to a new study published this week in the British Medical Journal. This study is not the first to show a link between shift work and heart health, but it is the largest-ever analysis of its kind. It pools together results from 34 previous studies on the topic, with a combined 2 million study participants from across the industrialized world, estimating that shift workers are at 23% greater risk of heart attacks than the other workers, 5% greater risk of ischemic strokes and 24% greater risk of all coronary events combined (a category that includes heart attack but not stroke). Shift workers also had slightly higher overall death rates than average, but those results were not statistically significant. (MORE: Working the Night Shift May Boost Breast Cancer Risk) In their analysis of shift work, the study&#8217;s authors included any regularly scheduled work outside of normal daytime hours — such as evening shifts, night shifts and early-morning shifts — as well as on-call or casual shifts, split shifts or irregular working hours, no matter what time of day that work typically occurred. In Canada (where many of the new study&#8217;s authors are based), about one-third of the workforce is engaged in shift work. What&#8217;s not clear, however, is why those workers have worse heart health. Shift workers may be engaged in a wide range of industries, from retail to health care to transportation, and they may be highly skilled employees, like medical doctors, or relatively unskilled, like fast-food workers. In their paper, the researchers write that shift work can disrupt sleep cycles and circadian rhythms, and that many night-shift workers in particular report insomnia, which is an independent risk factor for heart attack. (MORE: Why Shift Work and Sleeplessness Lead to Weight Gain and Diabetes) But irregular working hours can also be a source of stress. Erratic schedules make it tougher for people to organize convenient child care,<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=healthland.time.com&#038;blog=8684427&#038;post=64822&#038;subd=timewellness&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[Here&#8217;s another reason to log off at a reasonable hour: exposure to dim lighting at night — such as that generated by a TV screen, computer or night-light — may lead to depressive symptoms, new animal research suggests. A study from Ohio State University Medical Center found that hamsters with chronic exposure to dim light at night showed signs of depression within just a few weeks: reduced physical activity compared with hamsters living in normal light-dark conditions, as well as less interest in sugar water (a treat for the hamsters), greater signs of distress when placed in water, and changes in the brain&#8217;s hippocampus that are similar to brain changes seen in depressed people. &#8220;The results we found in hamsters are consistent with what we know about depression in humans,&#8221; Tracy Bedrosian, the first author the on the new study, told reporters. (MORE: TV, Video Games at Night May Cause Sleep Problems in Kids) Mood disorders are by no means the only health condition linked to artificial lighting and screen time at night. Earlier this year, the American Medical Association (AMA) put out a disturbing summary of adverse health effects from nighttime lighting, noting that artificial lights disrupt circadian rhythms and alter the body&#8217;s normal hormonal responses. In particular, when people spend too little time in darkness, it seems that the body suppresses release of the hormone melatonin, which — among other things — is thought to fight tumor growth and cancers. Other health conditions affected by changes in circadian rhythms, according to the AMA report, may include obesity, diabetes and reproductive problems. &#8220;The good news is that people who stay up late in front of the television and computer may be able to undo some of the harmful effects just by going back to a regular light-dark cycle and minimizing their exposure to artificial light at night,&#8221; Bedrosian says. &#8220;That&#8217;s what the results we found in hamsters would suggest.&#8221; Those animals&#8217; depressive symptoms, at least, went away once the hamsters returned to a schedule that included eight full hours of<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=healthland.time.com&#038;blog=8684427&#038;post=64529&#038;subd=timewellness&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[There&#8217;s no shortage of reasons that many Americans don&#8217;t get enough sleep: stress, obesity, late-night shifts on the job, to name just a few. Now new research suggests another factor to consider as well — their race or ethnicity. In two presentations at the annual meeting of the Associated Professional Sleep Societies in Boston, scientists report that the amount and quality of sleep people get each night vary across racial and ethnic lines. In one study, researchers found that blacks and Asians don&#8217;t sleep as much as whites do, while another study showed that foreign-born Americans are less likely to report having sleep problems than those born in the U.S. A better understanding of these discrepancies could help researchers improve the sleep habits of particular groups — a potential public-health boon, considering that inadequate sleep is increasingly associated with greater risks of chronic conditions like heart disease, diabetes, obesity and certain cancers. (MORE: Can&#8217;t Sleep? You May Be Afraid of the Dark) For the first study, led by Mercedes Carnethon, an associate professor of preventive medicine at Northwestern University, researchers randomly selected 439 Chicago-area adults from the phone book to participate. The volunteers, aged 35 to 64, were of white, black, Hispanic or Asian descent. Researchers screened the participants for sleep disorders like sleep apnea, and then asked them to wear a wrist monitor that detected their movements and determined how much time they spent sleeping over a period of seven days. The participants also self-reported the amount and quality of sleep they got each night. Overall, the researchers found, blacks, Hispanics and Asians slept less than whites. Blacks got 6.8 hours of sleep a night on average, compared with 6.9 hours for Hispanics and Asians, and 7.4 hours a night for whites. The differences in sleep times persisted even after the researchers adjusted for other factors known to interfere with sleep, such as weight, diabetes status, high blood pressure and other heart disease risk factors. The study authors also accounted for socioeconomic factors like low education and low income,<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=healthland.time.com&#038;blog=8684427&#038;post=61866&#038;subd=timewellness&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[Adults who routinely get less than six hours of shut-eye a night are four times more likely to suffer a stroke, compared with people getting seven or eight hours, according to a study recently presented at the SLEEP 2012 conference in Boston. To the surprise of the authors, the risk applied to adults who were at a healthy weight, had no risk factors or history of stroke and no increased risk for sleep apnea or other sleep problems. &#8220;People know how important diet and exercise are in preventing strokes,&#8221; lead author Megan Ruiter of the University of Alabama in Birmingham told USA Today. &#8220;The public is less aware of the impact of insufficient amounts of sleep. Sleep is important — the body is stressed when it doesn&#8217;t get the right amount.&#8221; The three-year study followed 5,666 adults aged 45 or older. The participants self-reported their sleep duration and stroke symptoms every six months. The researchers recorded the first stroke symptoms, as well as demographic information, stroke risk factors, depression symptoms and various health behaviors. In healthy people of normal weight, those who slept less than six hours a night were 4.5 more likely to suffer stroke symptoms than people getting seven or eight hours of sleep. Researchers didn&#8217;t find the same elevated risk in overweight or obese people. “Our thought is that habitually sleeping less than six hours is kind of like a precursor,” Ruiter told MSNBC. “It might kind of lead to some of these stronger and more severe risk factors later on.” Experts recommend that adults get about seven to nine hours of sleep a night, but according to recent data, about 30% of working American adults are eking by on six hours or less.

		<description><![CDATA[For some adults, insomnia may be caused by a fear of the dark, finds a new study by researchers at Ryerson University in Toronto. In the study of 93 students, nearly half acknowledged being afraid of the dark, and they were more likely to poor sleepers than good ones. &#8220;We never thought we would see this,&#8221; says Dr. Colleen Carney, assistant professor of psychology at Ryerson University. &#8220;We didn&#8217;t think people would admit or acknowledge this fear. They would say it&#8217;s for kids, or be too embarrassed.&#8221; (MORE: Getting More Sleep at Night May Help You Keep Slim) The participants filled out questionnaires on their sleep behavior, whether or not they had been afraid of the dark as children and they were still afraid of the dark. They also completed an insomnia assessment; based on their responses, the researchers divided the participants into two groups: good and poor sleepers. Following the questionnaires, the participants confirmed the participants&#8217; fear of the dark by putting them in either a dark or lit lab room and subjecting them to unexpected bursts of white noise. The researchers measured the students&#8217; blinking patterns, paying close attention to how they changed in response to the noises. &#8220;If you’re already a little anxious, the noise will make you flinch. We looked at eye reactions because it is one of the most robust ways to measure this anxiety. If you blink immediately after the noise, that means it startles you,&#8221; says Carney. The researchers found that when the lights went out, the poor sleepers were more easily startled than the good sleepers. The poor sleepers became increasingly anxious during their time spent in the dark, while the good sleepers responded less and less to the noises and appeared to get used to them. There was no difference between the groups&#8217; reactions in the light.&#8221;People who were poor sleepers experienced anticipatory anxiety in the dark, and based on the evidence, seem to be afraid of the dark,&#8221; says Carney.

		<description><![CDATA[Snoring and cover-hogging aside, studies increasingly suggest that couples enjoy health benefits just from sharing a bed. According to a round-up of emerging research by Wall Street Journal reporter Andrea Petersen, sleeping with a partner may be part of the reason that people in happy, committed relationships tend to have better health and longer lives than singletons. The new findings challenge previous studies showing that people move around more or don&#8217;t sleep as well when there&#8217;s someone else in their bed. Petersen cites a recent long-term study by Wendy M. Troxel, an assistant professor of psychiatry and psychology at the University of Pittsburgh, that found that women in stable relationships actually fell asleep faster and awoke less frequently during the night than single women or those whose relationship status changed over the study period. Another study in 2010 found that among 29 couples, women slept better at night when they had fewer negative interactions with their partners during the day; on days that women reported more harmony in their relationships, the men slept better too. (PHOTOS: The Artistry of Sleep: Photos of Icons Getting Some Shut-Eye) Essentially, the research suggests, the psychological benefits of bedding down with your loved may outweigh the costs of lost sleep or the hassles of sharing the sheets. Petersen reports: While the science is in the early stages, one hypothesis suggests that by promoting feelings of safety and security, shared sleep in healthy relationships may lower levels of cortisol, a stress hormone. Sharing a bed may also reduce cytokines, involved in inflammation, and boost oxytocin, the so-called love hormone that is known to ease anxiety and is produced in the same part of the brain responsible for the sleep-wake cycle. So even though sharing a bed may make people move more, &#8220;the psychological benefits we get having closeness at night trump the objective costs of sleeping with a partner,&#8221; Dr. Troxel says. But sometimes sharing sleep isn&#8217;t as easy as all that. What if your partner is a night owl and you&#8217;re a lark? Or what<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=healthland.time.com&#038;blog=8684427&#038;post=61085&#038;subd=timewellness&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[Sleepwalking is surprisingly common among Americans, with about 3.6% of U.S. adults — 8.5 million — rising in the wee hours of the night to wander around. A disorder caused by arousal from non-REM sleep, sleepwalking is very common during childhood and tends to decrease with age. &#8221;It&#8217;s dangerous because it is quite a lot of people,&#8221; says lead researcher Dr. Maurice Ohayon, a professor of psychiatry and behavioral sciences at Stanford University School of Medicine. &#8220;Sleep walking is less dangerous if you are home and there is someone to take care of you. But if you&#8217;re alone or not in your home, you could hurt yourself. You could fall or do something inappropriate.&#8221; (MORE: Sex while sleeping? A study suggest it’s not uncommon) The researchers looked at 15 states to select a representative sample of the general U.S. population. Using phone surveys, the team questioned 19,136 individuals about their sleep walking history, mental health, medical history and medication use. Participants were asked to report the frequency of sleepwalking episodes, the duration and any inappropriate or dangerous sleep behaviors. The researchers also asked about childhood sleepwalking and family history. They found that about 3.6% of the participants reported a minimum of one sleepwalking episode in the last year and 1% of participants reported sleepwalking two or more times in a month. The percentage of people who have sleepwalked at least once in their lives was 29.2%. Psychiatric disorders like depression and anxiety were also associated with sleepwalking. In the study, people with depression were 3.5 times more likely to sleepwalk than those without depression. Participants taking SSRI antidepressants were three times more likely to sleepwalk twice a month or more, although there was no significant link between sleeping pills and sleepwalking.  People with alcohol addictions and obsessive-compulsive disorder were also more likely to sleepwalk.
