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.
