Sleep better, parent better: Study shows link between maternal sleep and permissive parenting
A new study looks at the link between maternal sleep and permissive parenting during late adolescence. Findings show that mothers who don't get enough sleep or who take longer falling asleep have a greater tendency to engage in permissive parenting -- parenting marked by lax or inconsistent discipline.
CPAP may reduce resting heart rate in prediabetic patients
Patients with prediabetes who also have obstructive sleep apnea (OSA) may improve their resting heart rate, an important measure of cardiovascular health, by using continuous positive airway pressure (CPAP) to treat their OSA, according to a randomized, controlled trial.
New findings explain how melatonin promotes sleep
Researchers have discovered how melatonin suppresses neurons in the brain that keeps you awake and alert. These findings could lead to new therapies for those who suffer from insomnia.
Consumer sleep technology is no substitute for medical evaluation
Consumer sleep technology must be cleared by the Food and Drug Administration (FDA) and rigorously tested if it is intended to diagnose or treat sleep disorders, according to a position statement from the American Academy of Sleep Medicine.
Snorers suffer from nerve and muscle damage in the palate
People who snore may have extensive tissue damage in the nerves and muscles of the soft palate. This can in turn create problems with swallowing and contribute to development of sleep apnea. Treatment strategies aimed at early intervention to stop snoring might have beneficial effects in healing or preventing development of sleep apnea.
Adversity early in life linked with more physical pain in adulthood
Experiencing trauma as a child may influence how much pain an individual feels in adulthood. Gaining insight about who feels more pain and why is important as issues like the opioid crisis continue to escalate.
To treat pain, you need to treat the patient
People in chronic pain are some of the most difficult patients to treat. Clinicians found that an in-depth questionnaire can help immensely.
Noise throws the heart out of rhythm
With an increasing level of noise, the incidence of atrial fibrillation also increases dramatically. Scientists found that the incidence of atrial fibrillation in subjects with extreme noise annoyance reactions increases to 23 percent, compared to just 15 percent without this environmental impact. Looking at the proportion of sources of extreme noise pollution, aircraft noise came first with 84 percent during the day and 69 percent during sleep.
Effects of night-time light on internal body clock
New research has illuminated the effects of night-time light exposure on internal body clock processes. This is important for helping those who have poor quality sleep, such as shift workers, and could help improve treatments for depression.
Napping can help tired teens' performance in school
Researchers have found a positive relationship between midday-napping and nighttime sleep. They believe it might be key to boosting neurocognitive function in early adolescents. The team examined adolescents in Jintan, China, measuring midday napping, nighttime sleep duration and sleep quality, and performance on multiple neurocognitive tasks. Habitual nappers (who napped more often) tended to have a better nighttime sleep.
New link between sleep arousals and body temperature may also be connected to SIDS
What is the origin of these arousals? Scientists have discovered that brief arousals are probably triggered by the intrinsic electrical noise from wake-promoting neurons (WPN) in the brain. Their research reveals a previously unrecognized neurophysiological mechanism that links sleep arousals with temperature regulation, and may also provide an important new link between temperature and Sudden Infant Death Syndrome (SIDS).
Stress hormones spike as the temperature rises
A new study in medical students finds that summer, not winter, is the season when people are most likely to have higher levels of circulating stress hormones. These non-intuitive findings contradict traditional concepts of the taxing physical toll of winter and the relaxed ease of summer.

Later school start times really do improve sleep time
A new study indicates that delaying school start times results in students getting more sleep, and feeling better, even within societies where trading sleep for academic success is common.
Sleep deficiency increases risk of a motor vehicle crash
Individuals may be unaware of their degree of impairment from sleep deficiency, which raises the question of whether these individuals are at an increased risk of motor vehicle crash.
Infant death study reveals dangerous sleep practices among babysitters, relatives, others
Babies who died during their sleep while being watched by someone other than parents often had been placed in unsafe sleep positions, such as on their stomachs, or in unsafe locations, such as a couch, a new study has found.
Stroke affects more than just the physical
A new study looks at what problems affect people most after a stroke and it provides a broader picture than what some may usually expect to see. Stroke affects more than just physical functioning.
Moving light-dark exposure could reduce disruption faced by night shift workers
New research shows that our brain clock can be shifted by light exposure, potentially to align it with night shift patterns. It highlights that a 'one size fits all' approach to managing sleep disruption in shift workers may not be appropriate. A personalized approach, with light-dark exposure scheduled and taking into account whether someone is a 'morning' or 'evening' person, could reduce shift workers' risk of health problems.
Hormone imbalance may explain higher diabetes rates in sleep-deprived men
Studies have found an association between insufficient sleep and the development of insulin resistance, one of the factors that cause type 2 diabetes, and now researchers have discovered a biological reason for this relationship, at least in men: an imbalance between their testosterone and cortisol hormones.
New doctors' intense and changing schedules take a toll on sleep, activity and mood
This week, thousands of graduating medical students around the country will find out where they'll head next, to start their residency training. But a new study gives the first objective evidence of the heavy toll that the first year of residency can take on their sleep, physical activity and mood.
The brain puts the memories warehouse in order while we sleep
During the hours of sleep the memory performs a cleaning shift. A study reveals that when we sleep, the neural connections that collect important information are strengthened and those created from irrelevant data are weakened until they get lost.
Nightmares are common but underreported in US military personnel
A new study shows that a high percentage of military personnel with sleep disturbances met criteria for nightmare disorder, but few of them reported nightmares as a reason for sleep evaluation. Those with nightmare disorder had an increased risk of other sleep and mental health disorders.

Can't sleep? Could be down to genetics
Researchers have identified specific genes that may trigger the development of sleep problems, and have also demonstrated a genetic link between insomnia and psychiatric disorders such as depression, or physical conditions such as type 2 diabetes.
The brain's internal clock continually takes its temperature
Circuits in the brain act as an internal clock to tell us it is time to sleep and to control how long we then stay asleep. A new study in flies suggests a part of that clock constantly monitors changes in external temperature and integrates that information into the neural network controlling sleep.
Preschoolers exposed to nighttime light lack melatonin
A new study found that preschoolers exposed to bright light at bedtime had an 88 percent reduction in melatonin levels. Anatomical differences in their young eyes may make them more vulnerable to adverse impacts of bright light, the researchers say.
Sedative may prevent delirium in the ICU
A low dose of the sedative dexmedetomidine given at night may prevent delirium in critically ill patients, according to new research.
Study points to risk of future sleep breathing problems in college football players
Previous studies with older NFL football players have found a high incidence of sleep apnea, a serious health issue, among the group, particularly among older linemen. Now, a study with college-age linemen suggests that the roots of this health problem in football players may begin much earlier, and at an age when the condition is much less likely to occur in the general population. Body training specific to linemen appears to be related.
High blood pressure limits protection to vital organs and tissues in low-oxygen conditions
New research sheds light on the effects of high blood pressure by considering the way the body responds to a lack of oxygen.
Understanding a fly's body temperature may help people sleep better
In findings that one day may help people sleep better, scientists have uncovered the first molecular evidence that two anciently conserved proteins in the brains of insects and mammals share a common biological ancestry as regulators of body temperature rhythms crucial to metabolism and sleep. The scientists study fruit flies (Drosophila) and mice to solve mysteries about body temperature rhythms in insects and mammals.
Slow eating speed may be linked to weight loss
Slowing down the speed at which you eat, along with cutting out after dinner snacks and not eating within two hours of going to sleep may all help to shed the pounds, suggests new research.
Sleepless in Latin America: Blind cavefish, extreme environments and insomnia
A new study has found that differences in the production of the neuropeptide Hypocretin, previously implicated in human narcolepsy, may explain variation in sleep between animal species, or even between individual people. It may also provide important insight into the evolution of sleep and how we might build a brain that does not need to sleep.
Specific neurons trigger waking due to inhaled carbon dioxide
Researchers have shown that a group of neurons responsible for arousal are directly triggered by carbon dioxide and cause mice to wake up without any changes to breathing.
Body clock disruptions occur years before memory loss in Alzheimer’s
People with Alzheimer’s disease have disturbances in their internal body clocks that affect the sleep/wake cycle and may increase risk of developing the disorder. Researchers have found that such circadian rhythm disruptions also occur much earlier in people whose memories are intact but whose brain scans show early, preclinical evidence of Alzheimer’s.
Sixty-four percent of women suffer from insomnia in late pregnancy
A new study warns that health systems need to address the problem of insomnia in pregnancy systematically, since as well as affecting the quality of life of pregnant women, insomnia is a risk factor for high blood pressure and pre-eclampsia, gestational diabetes mellitus, depression, preterm birth and unplanned caesarean sections.
Quality of children's sleep may affect eating habits and weight
Several measures of poor sleep quality were associated with higher body mass index (BMI) in children, according to new data.

Stroke survivors, especially Mexican-Americans, whose sleep is interrupted by pauses in breathing (sleep apnea) are more likely to die or experience another stroke, according to preliminary research.
Americans are getting more ZZZZs
Although more than one in three Americans still don't get enough sleep, a new analysis shows first signs of success in the fight for more shut eye.
Who uses phone apps to track sleep habits? Mostly the healthy and wealthy in US
The profile of most Americans who use popular mobile phone apps that track sleep habits is that they are relatively affluent, claim to eat well, and say they are in good health, even if some of them tend to smoke.
Bright light therapy improves sleep in people treated for cancer
Results of a randomized controlled trial suggest that systematic bright light exposure can improve sleep for fatigued people who have been treated for cancer.
Newborn immune activation may have long-term negative impact on brain function
Neuroscientists have found that even a brief episode of immune system activation within days of birth can cause persistent changes in sleep patterns concurrent with increases in epilepsy-like brain activity -- a combination of symptoms common in autism spectrum disorder (ASD) and other developmental conditions.
Can writing your 'to-do's' help you to doze? Study suggests jotting down tasks can
Writing a 'to-do' list at bedtime may aid in falling asleep, according to a new study. Research compared sleep patterns of participants who took five minutes to write down upcoming duties versus participants who chronicled completed activities.
Housework gender differences may affect health in elderly men and women
Elderly men across Europe and the US spend less time on housework than elderly women, according to a new study. Researchers found that elderly women on average spent almost five hours a day doing housework compared to only around three hours a day for elderly men.
Sleeping for longer leads to a healthier diet
Sleeping for longer each night is a simple lifestyle intervention that could help reduce intake of sugary foods and lead to a generally healthier diet, according to a new study.
General anesthetics do more than put you to sleep
A new understanding of the complex ways in which general anesthetics act on the brain could eventually lead to improved drugs for surgery. It remains unclear how general anesthesia works, even though it is one of the most common medical procedures worldwide. University of Queensland researcher, Associate Professor Bruno van Swinderen, said his team had overturned previous understanding of what general anaesthetics do to the brain, finding the drugs did much more than induce sleep.
People who sleep less than 8 hours a night more likely to suffer from depression, anxiety
Sleeping less than the recommended eight hours a night is associated with intrusive, repetitive thoughts like those seen in anxiety or depression, according to new research.
Scheduled feeding improves neurodegenerative symptoms in mice
Restricting meals to the same time each day improves motor activity and sleep quality in a mouse model of Huntington's disease, according to new research. These findings suggest that eating on a strict schedule could improve quality of life for patients with neurodegenerative diseases for which there are no known cures.
With wrist-worn gadget, researchers capture real-life sleep for the first time
To measure a person's sleep, researchers have relied on costly and time-consuming approaches that could only be used in a sleep lab. But now researchers have found a way to capture detailed information on human sleep cycles over long periods of time while individuals slumber at home. According to the researchers, it will now be possible to objectively capture the real-life sleep habits and sleep quality of large numbers of people.
Preterm infants have narrowed upper airways, which may explain higher obstructive sleep apnea risk
A multidisciplinary team used MRI to determine that the risk factors that lead to obstructive sleep apena are confined to the uppermost airway and do not appear to be explained by enlarged adenoids and tonsils.
Weekly fish consumption linked to better sleep, higher IQ
Regular fish consumption has been shown to improve cognition. It's also been known to help with sleep. A new study connects all three for the first time. The team found that children who eat fish at least once a week sleep better and have higher IQs by an average of 4 points.
Seeing gene influencing performance of sleep-deprived people
Researchers have discovered a genetic variation that predicts how well people perform certain mental tasks when they are sleep deprived. For the first time, their research shows individuals with a particular variation of the DRD2 gene are resilient to the effects of sleep deprivation when completing tasks that require cognitive flexibility.
Some newborns with chronic illness show signs of serious sleep problems at birth
New parents often hear about how important sleep is for their babies' development -- but some newborns may have more serious sleep challenges than others. A new study finds that babies with spina bifida have early symptoms of sleep-disordered breathing that could contribute to lifelong issues with neurodevelopment.
