More often than not, you have a pretty good idea of what is keeping you awake at night — from the cat scratching at your bedroom door to the snoring partner next to you. But not all "sleep stealers" are obvious. Here are some big sleep stealers that could be keeping you up at night and you may not know it.
If you think your sleeping environment isn't perfect, try the bottom of the ocean. A recent study in the journal Biology Letters found that elephant seals while migrating from their breeding colonies in California to their wintering areas further north will roll over and sink to the seabed below for rest. A team of researchers tagged six juvenile elephant seals and released them 21 to 43 miles from their home at a reserve in California.
Sleep affects how we look, feel and perform on a daily basis and can have a major impact on our overall quality of life. When your body doesn't get the rest it needs, it will let you know — whether it's through fatigue or sickness as a result of a weakened immune system. A recent article in the Los Angeles Times looks at the negative effect a lack of sleep can have on your skin.
Nurses who work in intensive care units were found to have a low sleep quality, which might lead to more errors and affect patient safety, according to a study presented at the annual meeting of the American College of Chest Physicians. Researchers at Baylor College of Medicine in Houston compared the sleep quality and vigilance of nurses in intensive care with floor nurses. They found the average number of errors at the beginning and end of each shift was significantly different for intensive care nurses, but not floor nurses.
Fall is undeniably a great time of year for sleep enthusiasts because there's nothing better than gaining an hour of sleep. You might also find that it hurts a lot less than when you lose an hour in the spring, according to a new study in the Journal of Applied Psychology. Researchers at Michigan State University found that the return to daylight saving time in the spring can have a negative impact on injuries in the workplace.
A new study published by the Centers for Disease Control and Prevention finds a majority of Americans experience insufficient rest or sleep at least once during a 30-day period. The findings come from an analysis conducted in 2008 of data from all 50 states (as well as D.C. and three U.S. territories) using the Behavioral Risk Factor Surveillance System (BRFSS). The system, run by state health departments in conjunction with CDC, gathered information through a random telephone survey of more than 400,000 adults 18 years and older.
Millions of Americans will roll their clocks back one hour this weekend for the return to Standard Time. But as clocks move back and we wake on Sunday morning, after "gaining" an extra hour of the day, will Americans use that extra hour to catch up on their sleep? Probably not. According to the National Sleep Foundation's 2009 Sleep in America™ poll, two out of every ten Americans sleep less than six hours a night. Even with an extra hour, that's less than necessary for a full night's rest.
Much of our sleep patterns – feeling sleepy at night and awake during the day – are regulated by light and darkness. Light is the most powerful regulator of our biological clock. So what happens if you get too much light at night? According to EurekAlert, a recent study at Ohio State University looked at mice housed in a lighted room for 24 hours a day and mice housed in a room with a normal light-dark cycle. The study found that mice exposed to 24-hour light exhibited more symptoms of depression than the other mice.
Meir H. Kryger, MD, former chair of the National Sleep Foundation and editor of the Principles and Practice of Sleep Medicine, has compiled an atlas on sleep medicine that uses new scoring rules to help doctors score, interpret and diagnose sleep disorders. The book, the Atlas of Clinical Sleep Medicine: Expert Consult, is available in print and online, with more than 20 videos of patient interviews, over 40 sleep lab videos and 200 plus polysomnogram fragments.
The discovery by University of California, San Francisco, researchers of a genetic mutation that allows its carrier to function properly on less sleep than the average adult is opening scientists' eyes to the idea that our genes might actually determine sleep duration, according to a recent Forbes article. According to the article, disorders such as sleep apnea and narcolepsy have been traced to genetic variations and mutations. Dr.
