Missing Just 1 Hour of Sleep May Double Drivers' Crash Risk

Posted 1 day 23 hours ago by Drugs.com

TUESDAY, Dec. 6, 2016 – Missing just an hour or two of sleep at night nearly doubles your chances of a car crash the next day, a new report suggests. And getting behind the wheel after only four to five hours of shut-eye quadruples that risk. That's comparable to driving with a blood alcohol concentration considered legally drunk, the AAA Foundation for Traffic Safety researchers warned. "This is the first study to actually quantify the relationship between lack of sleep and the risk of being involved in a motor vehicle crash," said report author Brian Tefft, who added that the risk of sleep-impaired driving has long been "underestimated and underappreciated." The U.S. National Highway Traffic Safety Administration (NHTSA) recognizes the problem and will soon issue a national strategy to combat drowsy driving, said Bryan Thomas, the federal agency's communications director. "Not ... Read more

24-Hour Shifts Can Play Havoc With the Heart

Posted 6 days ago by Drugs.com

FRIDAY, Dec. 2, 2016 – Sleep deprivation while working 24-hour shifts affects heart function, a new German study suggests. "These findings may help us better understand how workload and shift duration affect public health," said lead researcher Dr. Daniel Kuetting, from the department of diagnostic and interventional radiology at the University of Bonn. "For the first time, we have shown that short-term sleep deprivation in the context of 24-hour shifts can lead to a significant increase in cardiac contractility [the degree to which heart muscle contracts], blood pressure and heart rate," Kuetting said. The study included 20 healthy radiologists with an average age of nearly 32 years. The participants' heart function was checked before and after a 24-hour shift in which they got an average of three hours of sleep. After the shift, the participants showed significant changes in blood ... Read more

Lack of Sleep Takes Big Bite Out of World Economies

Posted 8 days ago by Drugs.com

WEDNESDAY, Nov. 30, 2016 – Too little shut-eye can have far-reaching effects – even financial ones, a new report says. Reduced productivity and an increased risk of death linked to lack of sleep among U.S. workers cost the nation's economy as much as $411 billion a year. That's more than 2 percent of the country's gross domestic product (GDP), the report revealed. Lack of sleep leads to the loss of about 1.2 million working days a year in the United States. Sleep deprivation-related productivity losses are caused by employees missing work or working at less than ideal levels, said the study authors from the RAND Corp., a nonprofit research organization. Compared to someone who sleeps an average of seven to nine hours a night, the risk of death is 13 percent higher for those who sleep less than six hours a night, and 7 percent higher for those who sleep six to seven hours a night, the ...

Sleep Can Affect Male Fertility

Posted 19 Oct 2016 by Drugs.com

WEDNESDAY, Oct. 19, 2016 – Sleeping too little or too much can affect a man's ability to impregnate his partner, new research suggests. The "sweet spot" appears to be 7 to 8 hours of sleep a night, said study author Lauren Wise, a professor of epidemiology at Boston University School of Public Health. Among the 790 couples the researchers followed, "we found both short and long sleep duration – less than 6 hours or 9 or more per night – were associated with a reduced probability of pregnancy," Wise said. Using 8 hours of sleep as the reference point, men who slept less than 6 or more than 9 hours a night "had a 42 percent reduced probability of conception in any given month," she added. The main explanation is most likely hormonal, Wise said. Fertility experts know that testosterone is crucial for reproduction and the majority of daily testosterone release in men occurs during sleep, ... Read more

Health Tip: Making the Transition to Sleep

Posted 6 Oct 2016 by Drugs.com

-- It can be difficult to wind down from a busy day and prepare for sleep, as your body looks for cues that it's time to wind down. The National Sleep Foundation suggests: Before bed, dim the lights. This will help your body release more of the sleep-inducing hormone melatonin. Step away from smartphones, tablets and other electronics that can emit bright light. Finish all stimulating activities well before bedtime. Drop the thermostat to 60 to 68 degrees Fahrenheit at bedtime, which should help prepare you for sleep. Read more

Why Some Women Find Good Sleep Tough to Get

Posted 13 Sep 2016 by Drugs.com

MONDAY, Sept. 12, 2016 – Some women have trouble staying asleep, and a new small study may shed light on why. Women's internal, or circadian, body clocks run at a faster pace than men's, according to the research. It's as if women operate in a different "internal time zone," said study lead author Dr. Diane Boivin, professor of psychiatry at McGill University in Montreal. "They go to bed at a later biological time because their clock is shifted earlier, eastward," Boivin said. Boivin also directs the Centre for Study and Treatment of Circadian Rhythms at Douglas Mental Health University Institute in Montreal, a McGill affiliate. The way women sleep throughout the 24-hour circadian day also outpaces men, the study showed. Boivin said these two findings explain why women's sleep-wake cycle runs about two hours ahead of men. Women are more likely than men to report insomnia at least a few ... Read more

Health Tip: Find a Fun Alarm Clock

Posted 6 Sep 2016 by Drugs.com

-- If you have a tough time getting out of bed in the morning, a fun alarm clock that eases the transition into your day may help. Try these suggestions from the National Sleep Foundation: Look for an alarm clock that's functional, not just pretty. Make sure the buttons are easy to find when you're groggy first thing in the morning. Skip alarm clocks that emit bright blue light that can interfere with sleep. Opt for one that uses softer amber, orange or red to help you sleep more soundly. Choose an alarm clock that wakes you with a sound that you enjoy, whether that's the news, your favorite music or nature sounds. Consider one that gradually increases the volume to gently rouse you. Look for fun features that make sure you won't oversleep. Some alarm clocks have a light that turns on slowly at the time you should wake. Others vibrate the bed to help wake you. Read more

Sleep Is Key to College Success

Posted 17 Aug 2016 by Drugs.com

WEDNESDAY, Aug. 17, 2016 – It can be hard for college students to get enough sleep, and that can affect their physical and mental well-being, a sleep expert says. "A bad night's sleep or chronically not getting enough sleep can affect every aspect of our lives," said Dr. Aneesa Das, assistant director of the sleep medicine program at Ohio State University's Wexner Medical Center. "It can affect how we perform in school, our immunity and our emotions. When we're tired, we're more prone to infections, more likely to get into arguments and less likely to participate in activities we enjoy," she said in a university news release. One important tip is to keep up with schoolwork so you don't have to pull all-nighters. "When you are sleep-deprived, you don't think as clearly. Staying up all night to study can backfire and affect performance on exams. If you can't avoid an all-nighter, do it ... Read more

Don't Lose Sleep Over Screentime at Night

Posted 16 Aug 2016 by Drugs.com

TUESDAY, Aug. 16, 2016 – Daytime exposure to bright light may reduce the sleep-disrupting effects of blue light from smartphones and tablet computers, a new study suggests. Previous research has shown that evening use of devices that emit blue light interferes with sleep. In the new study, researchers at Uppsala University in Sweden assessed how evening use of a tablet computer affected 14 young people who had been exposed to bright light during the day. "Our main finding was that following daytime bright light exposure, evening use of a self-luminous tablet for two hours did not affect sleep in young healthy students," study first author Frida Rangtell said in a university news release. She is a doctoral student in neuroscience at Uppsala. Senior author Christian Benedict, an associate professor of neuroscience, said the results suggest that daytime exposure to bright light through ... Read more

Brain Relies on Two Timekeepers for Sleep

Posted 12 Aug 2016 by Drugs.com

FRIDAY, Aug. 12, 2016 – Both an internal "clock" and an internal "hourglass" affect how different parts of your brain respond to sleep deprivation, a new study shows. The Belgian researchers said these findings could eventually aid in the understanding of sleep disorders, and help folks who work night shifts or those with jet lag. The study involved 33 healthy young people who volunteered to stay awake for 42 hours and have their mental sharpness tracked along the way. Sleep scientists from the University of Liege used MRI scans to chart the volunteers' brain activity as they performed tests of attention and reaction time. Not surprisingly, their performances dulled as their sleep deprivation worsened. But the brain scans revealed a complicated interaction between two basic biological processes: the body's central "circadian rhythm," which pushes people to be awake and active during ... Read more

Drowsy Driving Causes 1 in 5 Fatal Crashes: Report

Posted 8 Aug 2016 by Drugs.com

MONDAY, Aug. 8, 2016 – Nearly 84 million sleep-deprived Americans take to the roads every day. And, drowsy driving was a factor in crashes that claimed about 5,000 lives last year, a new report shows. Traffic deaths rose almost 8 percent in the United States in 2015. Drowsy driving is estimated to cause up to 20 percent of all road fatalities, but the extent of the problem is not fully known, according to experts. The threat posed by tired drivers prompted the U.S. National Highway Traffic Safety Administration (NHTSA) to expand its definition of impaired driving to include not only drunk, drugged and distracted, but also drowsy driving. The annual cost to society of fatigue-related crashes that cause injury or death is $109 billion, not including property damage, according to a Governors Highway Safety Association (GHSA) report. But there are challenges associated both with measuring ... Read more

Could Slight Brain Zap During Sleep Boost Memory?

Posted 28 Jul 2016 by Drugs.com

THURSDAY, July 28, 2016 – Stimulating a targeted area of the brain with small doses of weak electricity while you sleep may enhance your ability to remember what you learned the night before, new research finds. The new procedure is called transcranial alternating current stimulation (tACS). "We work with the brain, that's really unique about what we do. We listen in to brain activity and can boost what the brain already wants to do," said the study's senior author, Flavio Frohlich. He's an assistant professor of psychiatry at the Neuroscience Center at the University of North Carolina in Chapel Hill. While you sleep your brain is not idle, but is actively storing things you learned during the day for later use. Stimulating the brain enhances what the brain is already doing naturally, Frohlich said. During sleep, electrical brain activity oscillates, and can be seen as waves on an ... Read more

Health Tip: Considering a Sleep Study?

Posted 21 Jul 2016 by Drugs.com

-- If you can't find a way to get to sleep, a sleep study may help you figure out what's behind your insomnia. The National Sleep Foundation says a sleep study may help if: Your doctor can't figure out what's causing your sleep problems. You've tried treatments for sleep issues without success. You have significant daytime drowsiness or chronic snoring. You wake up often throughout the night, or have trouble falling asleep. Read more

Sufficient Sleep May Help Protect Men Against Diabetes: Study

Posted 29 Jun 2016 by Drugs.com

WEDNESDAY, June 29, 2016 – Too much or too little sleep may raise the risk of diabetes in men, but not women, a study by European researchers suggests. "Even when you are healthy, sleeping too much or too little can have detrimental effects on your health. This research shows how important sleep is to a key aspect of health – glucose [sugar] metabolism," said senior study author Femke Rutters. She's with the VU Medical Center in Amsterdam, the Netherlands. The study involved nearly 800 healthy adults in 14 European countries. Compared to men who slept about seven hours a night, the men who slept the most or the least were more likely to have an impaired ability to break down sugar and to have higher blood sugar levels, the research found. This put them at increased risk for diabetes, the investigators said. But compared to women who slept an average amount, the women who slept the ... Read more
