A short nap can help relieve stress and bolster the immune systems of men who slept only two hours the previous night, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.
Vanderbilt biologists have found a direct link between the biological clock and Angelman syndrome, a neurogenetic disorder that occurs in more than one in every 15,000 live births. The link may provide a valuable way to judge the effectiveness of the first experimental drugs under development for treating the syndrome.
A team of Vanderbilt University biologists have found a way to use a laser and an optical fiber to reset an animal's master biological clock: A discovery that could in principle be used therapeutically to treat conditions like seasonal affect disorder, reduce the adverse health effects of night shift work and possibly even cure jet lag.
According to a new study by researchers from the Perelman School of Medicine at the University of Pennsylvania, only 25 percent of women who had reported no earlier sleep problems developed moderate or severe insomnia or other sleep disturbances during a 16-year period around menopause. What’s more, the researchers say that these sleep woes did not appear to be caused by menopause itself, which may quell common fears about symptoms associated with this phase of life.
Sound sleep in young and middle-aged people helps memory and learning, but as they hit their seventh, eighth and ninth decades — and generally don’t sleep as much or as well — sleep is not linked so much to memory, a Baylor University researcher says.
New research shows that stomach sleepers with epilepsy may be at higher risk of sudden unexpected death, drawing parallels to sudden infant death syndrome in babies. The study is published in the January 21, 2015, online issue of Neurology®, the medical journal of the American Academy of Neurology.
A good night’s sleep is linked to better performance by schoolchildren in math and languages – subjects that are powerful predictors of later learning and academic success, according to a study by researchers at McGill University and the Douglas Mental Health University Institute in Montreal.
Researchers hypothesize that targeting components of the mammalian clock with small molecules like REV-ERB drugs may lead to new treatments for sleep disorders and anxiety disorders. It also is possible that REV-ERB drugs may be leveraged to help in the treatment of addiction.
With an increase in parties, increased food and alcohol consumption and a general disruption of normal routines, the month of December can be exhausting. Here are three tips to improve sleep habits.
Insomnia can predict the appearance of back pain in adults
Studies have shown that periods of high stress and poor sleep can combine to increase the risk of having a migraine attack. Because stress levels are often high – and sleep insufficient -- during the winter holiday season, the American Migraine Foundation and its Chair, David W. Dodick, MD, FRCP (C), FACP, want to help people with migraine better understand some essentials of sleep hygiene that may help reduce their risk of migraine attacks. Dr. Dodick is also Professor of Medicine at the Mayo Clinic College of Medicine.
Sleep-deprived rats on chemotherapy drug Paclitaxal had worse side effects (extra rest later had no effect); religious beliefs can lead cancer patients to better care.
Sleep-related breathing problems and chronic lack of sleep may each double the risk of a child becoming obese by age 15, according to new research from Albert Einstein College of Medicine of Yeshiva University. The good news is that both sleep problems can be corrected. The study, which followed nearly 2,000 children for 15 years, published online today in The Journal of Pediatrics.
Researchers from the University of Missouri School of Medicine have found that drinking alcohol to fall asleep interferes with sleep homeostasis, the body’s sleep-regulating mechanism.
People who have sleep apnea or spend less time in deep sleep may be more likely to have changes in the brain that are associated with dementia, according to a new study published in the December 10, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Patients suffering from the world's most common heart rhythm disorder can have their long-term outcomes significantly improved with an aggressive management of their underlying cardiac risk factors, according to University of Adelaide researchers.
When you go to bed and how long you sleep at a time might actually make it difficult for you to stop worrying, according to researchers at Binghamton University. The study, led by Binghamton Anxiety Clinic Director Meredith Coles and graduate student Jacob Nota, found that people who sleep for shorter periods of time and go to bed very late at night are often overwhelmed with more negative thoughts than those who keep more regular sleeping hours. The findings appear in Springer’s journal Cognitive Therapy and Research, being published this month.
New research from the University of Adelaide has helped to shed light on the complexities of child sleep, and could lead to improved diagnosis of children with sleep-related breathing problems.
Penn Medicine researchers have developed a cognitive test battery, known as Cognition, for the National Space Biomedical Research Institute (NSBRI) to measure the impact of typical spaceflight stressors (like microgravity, radiation, confinement and isolation, exposure to elevated levels of CO2, and sleep loss) on cognitive performance. This computer-based test has already been tested by astronauts on Earth. It will be performed for the first time in a pilot study on the International Space Station (ISS) on November 28.
People with moderate to severe obstructive sleep apnea may have an intrinsic inability to burn high amounts of oxygen during strenuous aerobic exercise, according to a new study led by researchers at University of California, San Diego School of Medicine.
As real as that daydream may seem, its path through your brain runs opposite reality. Aiming to discern discrete neural circuits, researchers at the University of Wisconsin–Madison have tracked electrical activity in the brains of people who alternately imagined scenes or watched videos.
Older women with disordered breathing during sleep were found to be at greater risk of decline in the ability to perform daily activities, such as grocery shopping and meal preparation, according to a new study led by researchers at the Johns Hopkins Bloomberg School of Public Health and the University of California, San Francisco.
Insomnia is a "prevalent and persistent" problem for patients in the early phases of recovery from the disease of addiction—and may lead to an increased risk of relapse, according to a report in the November/December Journal of Addiction Medicine, the official journal of the American Society of Addiction Medicine. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
Service members diagnosed with chronic insomnia had a two times higher risk of developing hypertension and type II diabetes than military personnel who had not been diagnosed with the condition, according to a newly released health surveillance report of a study of the associations between these diseases.
After you roll your clocks back by an hour this Sunday, you may feel tired. That's because our bodies—more specifically, our circadian rhythms—need a little time to adjust. These daily cycles are run by a network of tiny, coordinated biological clocks. NIH's Mike Sesma tracks circadian rhythm research being conducted in labs across the country, and he shares a few timely details about our internal clocks.
Daylight saving time ends at 2 a.m. on Sunday, Nov. 2. As clocks turn back one hour, we gain an hour of sleep but often still feel groggy and sluggish. Vanderbilt Sleep Disorders Center specialist Kelly Brown, M.D., says this change in sleep schedule is exacerbated by our tendency to alter our sleep patterns on the weekends anyway.
Sleep apnea may affect your ability to form new spatial memories, such as remembering where you parked your car, new research led by NYU Langone Medical Center sleep specialists suggests. The study, published online Oct. 29 in Journal of Neuroscience, demonstrates through the playing of a specific video game that disruption of rapid eye movement (REM) sleep as a consequence of sleep apnea impairs spatial memory in humans even when other sleep stages are intact.
Most Americans who spend part of the year on daylight saving time look forward to the extra hour of sleep when it’s time to “fall back” to standard time. We are a nation of sleep-deprived people, and experts at The Ohio State University Wexner Medical Center say all ages suffer in various, unhealthy ways.
Workers punching in for the graveyard shift may be better off not eating high-iron foods at night so they don’t disrupt the circadian clock in their livers.
Memory decline — a frequent complaint of menopausal women — potentially could be lessened by hypnotic relaxation therapy, say Baylor University researchers, who already have done studies showing that such therapy eases hot flashes, improves sleep and reduces stress in menopausal women.
When the clocks “fall back” this year on Nov. 2, don’t let gaining an extra hour rob you of needed sleep. There’s plenty you can do now to establish healthy sleep habits and make it easier to reset your internal clock.
Reports of insomnia are common among the elderly, but a new study finds that sleep problems may stem from the quality of rest and other health concerns more than the overall amount of sleep that patients get.
Obesity is a risk factor for many health problems, but a new Penn Medicine study published this month in the journal Sleep suggests having a larger tongue with increased levels of fat may be a sign of obstructive sleep apnea (OSA) in obese adults.
Scientists have uncovered how pacemaker neurons are synchronized at dusk and dawn in order to maintain the proper functioning of their biological clocks. Their findings enhance our understanding of how sleep-wake cycles are regulated and offer promise for addressing related afflictions.
A new UI study finds twitches during rapid eye movement sleep comprise a different class of movement, which researchers say is further evidence that sleep twitches activate circuits throughout the developing brain and teach newborns about their limbs and what they can do with them.
Pain can make it difficult for some patients to get a good night’s rest while recovering in the hospital following certain surgical procedures, often resulting in longer hospital stays, according to researchers at Henry Ford Hospital in Detroit.
Scheduled for surgery? New research suggests that you may want to get screened and treated for obstructive sleep apnea (OSA) before going under the knife. According to a first-of-its-kind study in the October issue of Anesthesiology, the official medical journal of the American Society of Anesthesiologists® (ASA®), patients with OSA who are diagnosed and treated for the condition prior to surgery are less likely to develop serious cardiovascular complications such as cardiac arrest or shock.
Insomnia can cause chronic inflammation, which can lead to hypertension, diabetes, heart disease, and more. This study finds that curing the insomnia reduces the inflammation and hopefully reduces disease. It also found the best way to cure lack of sleep is through the use of a common psychotherapy treatment—cognitive behavioral therapy.
Caffeine therapy for apnea of prematurity has no long-term harmful effects on sleep or control of breathing, according to a new study of 201 preterm children assessed at ages 5-12, the first study in humans to examine the long-term effects of neonatal caffeine treatment on sleep regulation and ventilatory control.
Sleep, or lack thereof, and technology often go hand in hand when it comes to school-aged kids. Nearly three out of four children (72%) between the ages of 6 and 17 have at least one electronic device in their bedrooms while sleeping, according to a National Sleep Foundation survey. Children who leave those electronic devices on at night sleep less—up to one hour less on average per night, according to a poll released by the foundation earlier this year.
Sleep difficulties may be linked to faster rates of decline in brain volume, according to a study published in the September 3, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology.
The effectiveness of post-traumatic stress disorder (PTSD) treatment may hinge significantly upon sleep quality, report researchers at the University of California, San Diego School of Medicine and Veterans Affairs San Diego Healthcare System in a paper published today in the Journal of Neuroscience.
Pediatricians have a new prescription for schools: later start times for teens. Delaying the start of the school day until at least 8:30 a.m. would help curb their lack of sleep, which has been linked with poor health, bad grades, car crashes and other problems, the American Academy of Pediatrics (AAP) said in a new policy, which outlined chronic sleep deficits in our nation’s adolescents.
A study is shining new light on a sleep disorder called “sleep drunkenness.” The disorder may be as prevalent as affecting one in every seven people. The research is published in the August 26, 2014, print issue of Neurology®, the medical journal of the American Academy of Neurology.
According to researchers at the University of Montreal, the regions of the brain below the cortex play an important role as we train our bodies’ movements and, critically, they interact more effectively after a night of sleep. While researchers knew that sleep helped us the learn sequences of movements (motor learning), it was not known why.
College students are typically more sleep deprived than the rest of us and often ignore the health benefits of adequate slumber, said a researcher who studies the topic.
Reported online today in the journal Brain, findings from researchers at the University of Toronto and Harvard University show that a group of inhibitory neurons, whose loss leads to sleep disruption in experimental animals, are substantially diminished among the elderly and individuals with Alzheimer’s disease.
Researchers at UT Southwestern Medical Center have found a new way that internal body clocks are regulated by a type of molecule known as long non-coding RNA.
