Study: Frequent social media use linked to sleep disturbance

A recent study links frequent social media use is linked to sleep disturbances.

Young adults who spend a lot of time on social media during the day or check it frequently throughout the week are more likely to suffer sleep disturbances than their peers who use social media less, according to new research from the University of Pittsburgh School of Medicine.

Published online and scheduled for the April issue of the journal Preventive Medicine, the study indicates that physicians should consider asking young adult patients about social media habits when assessing sleep issues. The research was supported by the National Institutes of Health (NIH).

"This is one of the first pieces of evidence that social media use really can impact your sleep," said lead author Jessica C. Levenson, Ph.D., a postdoctoral researcher in Pitt's Department of Psychiatry. "And it uniquely examines the association between social media use and sleep among young adults who are, arguably, the first generation to grow up with social media."

In 2014, Dr. Levenson and her colleagues sampled 1,788 U.S. adults ages 19 through 32, using questionnaires to determine social media use and an established measurement system to assess sleep disturbances.

The questionnaires asked about the 11 most popular social media platforms at the time: Facebook, YouTube, Twitter, Google Plus, Instagram, Snapchat, Reddit, Tumblr, Pinterest, Vine and LinkedIn.

On average, the participants used social media a total of 61 minutes per day and visited various social media accounts 30 times per week. The assessment showed that nearly 30 percent of the participants had high levels of sleep disturbance.

The participants who reported most frequently checking social media throughout the week had three times the likelihood of sleep disturbances, compared with those who checked least frequently. And participants who spent the most total time on social media throughout the day had twice the risk of sleep disturbance, compared to peers who spent less time on social media.

"This may indicate that frequency of social media visits is a better predictor of sleep difficulty than overall time spent on social media," Dr. Levenson explained. "If this is the case, then interventions that counter obsessive 'checking' behavior may be most effective."

Senior author Brian A. Primack, M.D., Ph.D., assistant vice chancellor for health and society in Pitt's Schools of the Health Sciences, emphasized that more study is needed, particularly to determine whether social media use contributes to sleep disturbance, whether sleep disturbance contributes to social media use -- or both.

For example, social media may disturb sleep if it is:

• Displacing sleep, such as when a user stays up late posting photos on Instagram.
• Promoting emotional, cognitive or physiological arousal, such as when engaging in a contentious discussion on Facebook.
• Disrupting circadian rhythms through the bright light emitted by the devices used to access social media accounts.

Alternatively, young adults who have difficulty sleeping may subsequently use social media as a pleasurable way to pass the time when they can't fall asleep or return to sleep.

"It also may be that both of these hypotheses are true," said Dr. Primack, also director of Pitt's Center for Research on Media, Technology and Health. "Difficulty sleeping may lead to increased use of social media, which may in turn lead to more problems sleeping. This cycle may be particularly problematic with social media because many forms involve interactive screen time that is stimulating and rewarding and, therefore, potentially detrimental to sleep."

Military members and sleep problems

This article discusses the importance of sleep for members of the military, especially post-deployment.

Improving the quality and quantity of U.S. military members' sleep following deployment could help reduce other health problems, including depression and post-traumatic stress disorder, according to a new RAND Corporation study.

However, a lack of consistent and transparent sleep-related policies may impede efforts to promote sleep health among service members, researchers say.

"The U.S. military has shifted from combat operations in Iraq and Afghanistan toward helping service members and veterans reintegrate into noncombat roles," said Wendy Troxel, co-leader of the study and a behavioral scientist at RAND, a nonprofit research organization. "One issue that is often overlooked once military men and women return home is that of persistent sleep problems, because in many ways such problems are viewed as endemic to military culture."

Sleep disturbances are a common reaction to stress and are linked to a host of physical and mental health problems. Sleep problems often follow a chronic course, persisting long after service members return home from combat, with consequences for their reintegration and the readiness and resiliency of the force, researchers say.

The RAND report is the first comprehensive review of sleep-related policies and programs across the U.S. Department of Defense, examining the frequency of sleep disorders and factors that contribute to the problem. A survey of nearly 2,000 service members from all branches of the U.S. military found sleep problems had negative effects on mental health, daytime functioning and perceived operational readiness.

"Military policies on prevention of sleep problems are lacking, and medical policies focus on treating mental disorders that are often linked with sleep problems, instead of sleep itself," said Regina Shih, project co-leader and a senior social scientist at RAND. "We know that sleep problems may precede the onset of mental disorders."

While there may be stigma about seeking sleep treatment, it may be lower than the stigma associated with seeking help for mental health problems. Researchers say this suggests sleep could be a gateway to improving psychological health and readiness in service members.

Researchers say that historically, military cultural attitudes have tended to discount the importance of sleep. For example, service members noted that depriving oneself of sleep is often seen as a badge of honor and acknowledging the need for sleep can be seen as a sign of weakness.

The study recommends widespread education and awareness programs within the Defense Department as one means of shifting these cultural attitudes. In operational contexts, the military emphasizes mission first and the need for sleep may be sacrificed for operational demands. Policies are needed to educate service members and leaders about the importance of sleep, including awareness on the importance of sleep for resilience.

Leaders are not always sure how to develop and execute sleep plans that can balance circadian rhythms with the realities of operational environments, or how to allow for adequate recovery periods after extended sleep deprivation in order to optimize force readiness.

The RAND study presents 16 policy recommendations to help the military improve the prevention, identification and treatment of sleep problems in service members. Those policies fall under four broad categories: prevention of sleep problems; increasing identification and diagnosis of sleep problems; ways to clinically manage sleep disorders and promote sleep health; and ways to improve sleep in training and operational contexts.

Is melatonin safe for children?

This article discusses the research that has been done on melatonin and children.

Melatonin hormone should be made easily available according to some sleep experts despite the conflict of interest among researchers as to whether it is safe for inducing sleep in children or not, reports The Sydney Morning Herald.

Melatonin is a natural hormone secreted by the pineal gland of the body. The small pea-sized gland which is located just above the middle of the brain is inactive during the day and gets turned on by the suprachiasmatic nucleus (SCN) located in the hypothalamus when it gets dark. It then secretes the melatonin in the blood which is responsible for inducing sleep naturally.

Sleep plays a vital part during the early development of brain in the newborns. The Circadian rhythm or the sleep-wake cycle in the body is regulated by the light and dark and it takes time to develop, resulting in the irregular sleep schedules of newborns. The rhythms begin to develop at about six weeks, and by three to six months most infants have a regular sleep-wake cycle.

However, 30 percent of children aged under three suffer from sleep problems, with the most common causes which are either behavioral or medical, according to a Monash University study.

Pediatric sleep specialist Dr Chris Seton, Woolcock Institute of Medical Research says, melatonin is a better alternative to the antidepressants and blood pressure medication that is commonly used by the parents which cause severe side effects.

But the medical experts do not seem to be readily accepting the claim as some of the research reveals that melatonin could adversely affect development during adolescence. They also have raised concern over the increasing trend of use of the hormone for treating sleep related issues in children.

There are reports which say that children with epilepsy and cerebral palsy were prescribed with melatonin way back since 1991. But it is now believed children with behavioural issues, such as ADHD, are more likely to be given melatonin now.

A senior research fellow at The University of Adelaide, David Kennaway says that the studies done on adults and animals have linked melatonin to a negative impact on reproductive, immune, cardiovascular and metabolic systems. In a research article published in the Journal of Paediatrics and Child Health, he says “It is not registered for use in children anywhere in the world and it has not undergone the formal safety testing expected for a new drug, especially long-term in children.”

But Dr Chris Seton, feels otherwise and says,”There is no evidence that it’s anything but a very safe drug. In the contexts of drugs given to kids, it’s at the top in terms of safety”.

The Sleep Health Foundation has cautiously approved the use of melatonin in children, stating it “appears to be safe and works well in the short term”.

Children's academic performance and sleep

This article explains how academic performance in children is affected by their sleep.

Making sure school-aged kids get to sleep at a regular hour is often a struggle for parents. But a study by researchers at McGill University and the Douglas Mental Health University Institute in Montreal suggests it's well worth the effort: the researchers found that a good night's sleep is linked to better performance in math and languages -- subjects that are powerful predictors of later learning and academic success.

In findings published recently in the journal Sleep Medicine, the researchers reported that "sleep efficiency" is associated with higher academic performance in those key subjects. Sleep efficiency is a gauge of sleep quality that compares the amount of actual sleep time with the total time spent in bed.

While other studies have pointed to links between sleep and general academic performance, the Montreal scientists examined the impact of sleep quality on report-card grades in specific subjects. The upshot: with greater sleep efficiency, the children did better in math and languages -- but grades in science and art weren't affected.

"We believe that executive functions (the mental skills involved in planning, paying attention, and multitasking, for example) underlie the impact of sleep on academic performance, and these skills are more critical in math and languages than in other subjects," says Reut Gruber, a clinical child psychologist who led the study. Low academic achievement in children is a common and serious problem that affects 10-20 % of the population. "Short or poor sleep is a significant risk factor for poor academic performance that is frequently ignored," says Gruber, who is a researcher at the Douglas Institute and professor in McGill's Department of Psychiatry.

Gruber's research team, in collaboration with the Riverside School Board in Saint-Hubert, Quebec, studied 75 healthy children between 7 and 11 years of age. The children's nighttime sleep was monitored by actigraphy, which uses a wristwatch-like device to evaluate sleep by measuring movements. "We averaged the data over five nights to build the children's habitual sleep patterns and correlated the data with their report-card grades," Gruber says.

The takeaway for parents

The findings underscore the importance of identifying sleep issues that may otherwise go unnoticed, Gruber says. That doesn't mean parents need to rush out and have their kids tested at sleep clinics -- but it does point to a need for pediatricians to incorporate questions about sleep into routine checkups, she adds.

"I think many kids might have some sleep issues that nobody is aware of," she says. "And if the pediatrician doesn't ask about it, we don't know that it's there. Regular screening for possible sleep issues is particularly important for students who exhibit difficulties in math, languages or reading."

Differences in sleep issues between women and men

This article explains the differences in sleep issues faced by women and men.

As a nation we are severely sleep-deprived. According to data from the Centers for Disease Control and Prevention, as much as a third of all Americans do not get the recommended seven hours of sleep a night.

"One of the myths is that we can power through or sleep when we're dead," Dr. Charles Czeisler, chair of the National Sleep Foundation and director of sleep medicine at Harvard Medical School, told "CBS This Morning." "But of coursewe'll get there faster if we don't get enough sleep. "

Women and men run into different roadblocks when it comes to their quest for a good night's sleep.

Women are more likely to toss and turn frequently and fight bouts of insomnia, a result of differences in hormonal regulation. Estrogen tends to shorten the length of the sleep cycle, which is why women often report that they experience sleep troubles around the time of menstruation, pregnancy or menopause.

According to a poll taken by the National Sleep Foundation, 63 percent of women versus 54 percent of men experience insomnia at least few nights a week. Women are also more likely to experience daytime sleepiness.

"One of the things is the internal clock controls the timing of sleep," said Czeisler. "It runs faster in women than it does men. It's only about a tenth of an hour but it adds up so that women, in general, their internal clocks are set to about an hour or an hour and half earlier than men, and that means it wakes them up earlier in the morning and it's harder to stay awake in the evening."

On the other hand, anatomical differences in men mean they're more likely to have sleep apnea -- a result of more fat deposit around the neck. Approximately 17 percent of men and 9 percent of women are diagnosed with sleep apnea, a type of sleep disorder that is caused by infrequent or paused breathing.

"If you crowd out the airway then you're going to have trouble when you sleep," said Czeisler. "One out of 3 men and about 1 out of 6 women suffer from disturbed sleep disordered breathing. But unfortunately, because it tends to be viewed as a male dominated disease women are much less likely to be diagnosed. Only 1 out of 10 women compared with men get diagnosed for sleep apnea."

Regardless of these challenges, everyone can take a number of measures to avoid sleep deprivation. Czeisler says good sleep hygiene is essential, such as going to bed at the same time each night to regulate your circadian rhythm. Some people find it helpful to set an alarm for bedtime. Creating a bedroom that's conducive to sleeping is also essential: remove all electronics from the bedroom and keep your room cool and dark.

Sleep issues in children with mental health diagnoses

Sleep issues are common among children with mental health diagnoses, and may go undiagnosed due to the co-existing conditions.

Sleep difficulties, particularly problems falling asleep, are common among toddlers and preschoolers with mental health issues, according to a new study.

"Sleep problems in young children frequently co-occur with other behavioral problems, with evidence that inadequate sleep is associated with daytime sleepiness, less optimal preschool adjustment, and problems of irritability, hyperactivity and attention," said the study's leader, John Boekamp, clinical director of the pediatric partial hospital program at Bradley Hospital in Providence, R.I.

However, he said, sleep disorders may be unrecognized and underdiagnosed in young children, particularly when behavioral or emotional problems are present.

The study, published online in Child Psychiatry & Human Development, involved 183 children aged 6 years or younger receiving outpatient treatment for psychiatric problems. The researchers examined the prevalence of sleep disorders among these children and the nature of the sleep problems.

"The most common sleep difficulties reported nationally for toddlers and preschoolers are problems of going to bed, falling asleep and frequent night awakenings. Collectively, these problems are referred to as behavioral insomnias of childhood," said Boekamp in a hospital news release.

Recognized sleep disorders, particularly sleep onset insomnia, were more common than expected, the researchers found. Overall, 41 percent of children in the study met the criteria to diagnose a sleep disorder.

Sleep problems were most common in kids with disruptive behavior, and attention, anxiety and mood problems, the researchers found.

Early sleep problems could not only be the result of behavioral and emotional problems, but could also contribute to them, the researchers noted.

"Essentially, these young children might be caught in a cycle, with sleep disruption affecting their psychiatric symptoms, and psychiatric symptoms affecting their sleep-wake organization," said Boekamp. "It is important for families to be aware of how important sleep is to the behavioral adjustment and well-being of young children."

Sleep problems can complicate treatment for challenging behaviors, such as aggression and attention and mood problems. Daytime sleepiness and fatigue can make these problems even worse, the study's authors noted.

"This study is a great reminder that it's critical for mental health providers working with young children and their families to ask about children's sleep," said Boekamp.

"Simple questions about children's sleep patterns, including how long it takes a child to fall asleep at night and how frequently a child awakens after falling asleep, may yield important information that is relevant to clinical care, even when sleep problems are not the primary focus of treatment," he explained.

Study: Self-reported sleep issues increase Alzheimer's riskhttp://i.dailymail.co.uk/i/pix/2012/03/01/article-2108664-11FCB218000005DC-905_468x338.jpg

According to a study, older males self-reporting sleep issues increases his risk of developing Alzheimer's disease.

In a new study, researchers from Uppsala University demonstrate that elderly men with self-reported sleep disturbances run a higher risk of developing Alzheimer's disease than men without self-reported sleep disturbances. The results are published in the scientific journal Alzheimer's & Dementia.

The researchers followed more than 1,000 men, who were initially 50 year old, between the years 1970 and 2010. The results of the study show that self-reported sleep disturbances were linked to an increased risk for Alzheimer's disease during the 40-year follow-up period, particularly if they occurred late in life. The data suggest that a regular good night's sleep could support brain health in men.

'We demonstrate that men with self-reported sleep disturbances run a 1.5-fold higher risk to develop Alzheimer's disease than those without reports of sleep disturbances during a 40-year follow-up period. The later the self-reported sleep disturbance was found the higher the risk was for developing Alzheimer's disease. These findings suggest that strategies aimed at improving sleep quality in late life may help reduce the risk to develop Alzheimer's disease', says Christian Benedict, sleep researcher at Uppsala University, who led the study.

"Importantly, there are several lifestyle factors, such as exercise, that can influence your brain's health. Thus, it must be borne in mind that a multifaceted lifestyle approach comprising good sleep habits is essential for maintaining brain health as you age," says Christian Benedict.

In an earlier article published in the journal Sleep, Christian Benedict and colleagues showed that a single night of total sleep deprivation increased blood concentrations of brain molecules in young men that typically rise in blood upon acute brain damage.

Study: Sleep issues common for children with psychiatric disorders

A study found that sleep issues are more common for children with a psychiatric disorder.

John Boekamp, Ph.D., clinical director of the Pediatric Partial Hospital Program (PPHP) at Bradley Hospital recently led a study that found sleep difficulties - particularly problems with falling asleep - were very common among toddlers and preschool-aged children who were receiving clinical treatment for a wide range of psychiatric disorders. The study, titled "Sleep Onset and Night Waking Insomnias in Preschoolers with Psychiatric Disorders," is now published online in the journal Child Psychiatry & Human Development.

"The most common sleep difficulties reported nationally for toddlers and preschoolers are problems of going to bed, falling asleep and frequent night awakenings – collectively, these problems are referred to as behavioral insomnias of childhood," said Boekamp. "Sleep problems in young children frequently co-occur with other behavioral problems, with evidence that inadequate sleep is associated with daytime sleepiness, less optimal preschooladjustment, and problems of irritability, hyperactivity and attention."

Boekamp's team was interested in learning more about sleep and sleep problems in young children with behavior problems, as early sleep problems may be both a cause and consequence of children's difficulties with behavioral and emotional self-regulation. "Essentially, these young children might be caught in a cycle, with sleep disruption affecting their psychiatric symptoms and psychiatric symptoms affecting their sleep-wake organization," said Boekamp.

The partial program that Boekamp leads at Bradley Hospital is a family-centered, intensive day treatment program for very young children aged from newborn to six who have serious emotional, behavioral or relationship disturbances. This study examined the nature and prevalence of diagnostically defined sleep disorders, including Sleep Onset Insomnia (SOI) and Night Waking Insomnia (NWI), in a group of 183 young children admitted to the program. Diagnosable sleep disorders, particularly SOI, were quite common in the group, exceeding previous estimates obtained in community settings. Overall, 41 percent of children in the study also met diagnostic criteria for a sleep disorder. Sleep problems were especially common in children with disruptive behavior, attention, anxiety and mood problems.

"It is important for families to be aware of how important sleep is to the behavioral adjustment and wellbeing of young children," said Boekamp. "Sleep disorders may be unrecognized and under-diagnosed in young children, particularly when other behavioral or emotional problems are present."

Difficulties with sleep may be particularly important to address when children are also struggling with challenging daytime behaviors, such as problems with compliance, aggression, attention and mood. Sleepiness and fatigue may exacerbate these problem behaviors.

"This study is a great reminder that it's critical for mental health providers working with young children and their families to ask about children's sleep," said Boekamp. "Simple questions about children's sleep patterns, including how long it takes a child to fall asleep at night and how frequently a child awakens after falling asleep, may yield important information that is relevant to clinical care, even when sleep problems are not the primary focus of treatment."

Caffeine therapy, preemies, and sleep trouble

A study found that preemies are at risk for having sleep issues and sleep disorders later in life, regardless of any caffeine therapy they may have had in the NICU.

Using caffeine to treat premature newborns for apnea - dangerous pauses in breathing during sleep - does not have long-term harmful effects on their sleep or breathing patterns, according to research led by Children's Hospital of Philadelphia. 

But the new study also found that prematurity itself is a risk factor for sleep disorders years later. Children born preterm had high rates of obstructive sleep apnea and periodic limb movement during sleep, whether or not they had caffeine therapy in the neonatal intensive care unit.

The very idea of caffeinating fragile preemies may sound misguided. But eight years ago, an international study that compared the stimulant to a placebo found it had benefits, including relieving sleep apnea.

Still, there were lingering concerns. Caffeine works in the brain, blocking a molecule that promotes sleep. Animal studies suggest that such early biochemical tinkering can lead to permanent sleep and breathing abnormalities.

"I think we all know from daily life the effect that caffeine has on us," said lead author Carole L. Marcus, a pediatric pulmonologist and director of the sleep center at Children's Hospital. "We give the equivalent of six cups of coffee a day for a week or more - and these are little babies whose brains are still developing."

The new study, published Friday in the American Journal of Respiratory and Critical Care Medicine, tracked down 201 of the original 2006 premature babies, now ages 5 to 12. Half had gotten caffeine therapy, the other half a placebo.

For two weeks, the children wore a noninvasive sensor at night to monitor their sleep. The parents also filled out questionnaires.

There were no differences in the children's sleep patterns, including how long they took to fall asleep and how soundly they slept.

But both caffeine and placebo groups had high rates of sleep disorders. Overall, about 10 percent had periodic limb movement disorder (episodes of involuntary movement, usually of the legs), and 14 percent had obstructive sleep apnea. In general, less than 4 percent of school-age children have apnea, and 5 percent to 8 percent have the limb movement disorder.

Obstructive sleep apnea is different from the apnea of prematurity. In the obstructive form, the throat airway collapses or becomes blocked. In preemies, breathing stops because their immature nervous systems cannot yet enable continuous respiration.

Obstructive apnea can lead to daytime sleepiness, learning problems, high blood pressure, and heart disease. Limb movement disorder is less understood but has been linked to attention deficit hyperactivity disorder and a serious sleep problem called restless leg syndrome.

If caffeine isn't a culprit, why are sleep disorders common in former premature babies?

One possibility, the researchers noted, is enlarged tonsils. About a quarter of the children had already undergone tonsillectomies, the primary treatment for childhood obstructive sleep apnea.

"We're thinking the rate of apnea would have been even higher if not for the tonsillectomies," Marcus said.

The limb movement may be related, at least partly, to iron deficiency. Low blood iron levels were found in the children with the movement disorder who underwent testing.

All the children with apnea or limb movement disorder were referred for more testing and treatment, but most former preemies are not even checked for such problems. The study suggests that should change.

"We should be screening these children," Marcus said. "Then we could prevent problems, or treat them earlier."

What causes sleep issues for Parkinson's patients?

This article discusses the link between Parkinson's disease and sleep issues, and what may cause sleep issues for people with Parkinson's disease.

Up to 70% of Parkinson’s disease (PD) patients experience sleep problems that negatively impact their quality of life. Some patients have disturbed sleep/wake patterns such as difficulty falling asleep or staying asleep, while other patients may be subject to sudden and involuntary daytime sleep “attacks.” In the extreme, PD patients may exhibit REM-sleep behavior disorder (RBD), characterized by vivid, violent dreams or dream re-enactment, even before motor symptoms appear. A review in the Journal of Parkinson’s Disease discusses the underlying causes of sleep problems in PD, as well as medications, disease pathology, and comorbidities, and describes the most appropriate diagnostic tools and treatment options.

Sleep problems in PD patients can have wide-ranging adverse effects and can worsen in later stages of the disease. Sleepiness socially isolates patients and excessive sleepiness can put patients at risk of falls or injury, and can mean patients must give up driving. Sleepiness can impair cognition and concentration, exacerbate depression, and interfere with employment. Wakefulness at night impairs daytime wakefulness and may also cause mood instabilities and can exhaust caregivers.

“Diagnosis and effective treatment and management of these problems are essential for improving the quality of life and reducing institutionalization of these patients,” says lead author Wiebke Schrempf, MD, Technische Universität Dresden, Faculty of Medicine Carl Gustav Carus, Department of Neurology, Division of Neurodegenerative Diseases, Dresden, Germany.

Dr. Schrempf and colleagues describe some of the complexities associated with treating sleep problems in PD patients, such as the worsening of sleep problems by dopaminergic medications used to treat motor symptoms. Lower doses of levodopa or dopamine agonists are able to improve sleep quality partly by reducing motor symptoms such as nighttime hypokinesia (decreased body movement), dyskinesia (abnormal voluntary movements), or tremor (involuntary shaking), which interfere with normal sleep. However, the same medications may also cause excessive daytime sleepiness. The report describes how changing medication, dose, duration of treatment, or timing of administration can improve outcomes.

The presence of other conditions common in PD patients such as depression, dementia, hallucinations, and psychosis may interfere with sleep. Unfortunately, some antidepressants can also impair sleep.

Sleep problems may also be harbingers of future neurodegenerative disease. Patients with RBD exhibit intermittent loss of normal muscle relaxation during REM sleep and engage in dream enactment behavior during which they may shout, laugh, or exhibit movements like kicking and boxing. “RBD seems to be a good clinical predictor of emerging neurodegenerative diseases with a high specificity and low sensitivity, whereas other early clinical features of PD, such as olfactory dysfunction and constipation, are less specific,” says Dr. Schrempf. “These early clues may help identify PD patients before motor symptoms appear, when disease-modifying therapies may be most beneficial.”

PD is the second most common neurodegenerative disorder in the United States, affecting approximately one million Americans and five million people worldwide. Its prevalence is projected to double by 2030. The most characteristic symptoms are movement-related, such as involuntary shaking and muscle stiffness. Non-motor symptoms, such as worsening depression, cognition, and anxiety, olfactory dysfunction, and sleep disturbances, can appear prior to the onset of motor symptoms.

Pregnant women with hypertension and who snore may have a sleep disorder

A study shows that nearly half of pregnant women with hypertension and who snore may also have an undiagnosed sleep disorder.

One in two hypertensive pregnant women who habitually snore may have unrecognized obstructive sleep apnea, a sleeping disorder that can reduce blood oxygen levels during the night and that has been linked to serious health conditions, new University of Michigan-led research shows.

One in four hypertensive pregnant women who don't snore also unknowingly suffer from the sleeping disorder, according to the study that appears in the British Journal of Obstetrics and Gynecology.

"We know that habitual snoring is linked with poor pregnancy outcomes for both mother and child, including increased risk of C-sections and smaller babies," says lead author Louise O'Brien, Ph.D., M.S., associate professor at U-M's Sleep Disorders Center in the Department of Neurology and adjunct associate professor in the Department of Obstetrics & Gynecology at the U-M Medical School.

"Our findings show that a substantial proportion of hypertensive pregnant women have obstructive sleep apnea and that habitual snoring may be one of the most telling signs to identify this risk early in order to improve health outcomes."

Habitual snoring – snoring three or more nights a week – is the hallmark symptom of obstructive sleep apnea, which has been shown to increase in frequency during pregnancy. and affects up to one-third of women by the third trimester.

O'Brien's previous studies have found that snoring during pregnancy may influence delivery and baby's health, with a higher risk for C-sections and delivering smaller babies. Women who begin snoring during pregnancy are also at a strong risk for high blood pressure and preeclampsia, O'Brien's research has shown.

"Hypertensive pregnant women who report snoring should be evaluated for obstructive sleep apnea since sleep apnea can be treated during pregnancy," says O'Brien, who is also a member of the Institute for Healthcare Policy and Innovation.

"Prompt recognition, evaluation, and management will not only improve health benefits for both moms and babies but may also help cut the high healthcare expenses of operative deliveries, taking care of babies who are admitted to the NICU and other associated health risks."

Sleep issues can lead to heart conditions

This article discusses how snoring and other sleep issues can lead to heart conditions.

Adequate amount of quality sleep is very essential to maintain good health, replenish energy, and restore the mind. It plays a vital role in maintaining a healthy balance of hormones, strengthening the immune system, sustaining proper brain function, and supporting healthy growth and development. Sleep-related disorders are one of the most commonly encountered problems today and can immensely affect your physical and mental health, cognitive capacity, productivity, quality of life, and safety.

Research shows that sleep disorders and heart disease are closely linked and one condition can lead to the other. Your heart, being only a little larger than a fist, works hard to pump almost 2,000 gallons of blood each day. Sleep provides your heart a chance to slow down, and your breathing and blood pressure drop to levels lower than what occurs while you are awake. Lack of sleep can lead to several heart-related conditions which include:

High blood pressure

Chest pain

Hardening of arteries (atherosclerosis or cholesterol-clogged arteries)

Heart attack

Stroke

Coronary heart disease

Congestive heart failure

Congenital heart defects

Studies have shown that habitual loud snorers are at a considerably higher risk of developing heart disease and stroke as compared to people who never or rarely snore. As you sleep, the soft tissue at the back of your head and neck relaxes and gradually narrows the airways, causing you to snore. Certain factors such as obesity, smoking, consumption of alcohol, allergic reactions, and muscle relaxing antidepressants and sedatives are known to increase the risk of persistent snoring. If not treated, snoring usually gets worse over time, causing the muscles to get weaker and making it harder to keep the airways open.

Patients with sleep disorders are often sleepy during the day and have reduced ability to concentrate, remember, or think, and are at a higher risk of falling asleep while driving or working. Studies have shown that proper treatment of sleep apnea greatly reduces your risk of developing heart-related conditions and, in addition, improves pre-existing cardiac disorders. Medical treatment for sleep disorders may involve the following:

• Weight loss if you are overweight.
• Avoiding drugs/habits that increase the risk of sleep apnea such as sleeping pills, sedatives, alcohol, and tobacco smoking.
• Using Continuous Positive Airway Pressure (CPAP) -- a slightly pressurized mask is fit over the nose or over the nose and mouth to hold the airway open and allow the patient to sleep normally.
• Surgery on the upper airway (if your doctor thinks you are a candidate for surgery) -- enlarging the air passage by removing the uvula and some of the surrounding tissue.
• Wearing a dental device or mouth guard that is designed to move the lower jaw slightly down and outwards helps keep the airway open during sleep.
• Getting a polysomnogram -- a sleep study that is usually done overnight in a sleep center. It electronically transmits and records your brain waves, heart rate, breathing patterns, oxygen levels in the blood, your eye and limb movements, and muscle tension as you sleep. A sleep specialist analyzes the quality of your sleep and determines whether or not you have a sleep order.

Sleep disorders are very common and are often ignored by patients. You should talk to your doctor about your risk of having a sleep disorder and get regular medical check-ups. A timely diagnosis and early medical treatment can help you recover from your sleep disorder and reduce the risk of other serious health issues. It is important to remember that good quality sleep is more of a necessity than a luxury for better cardiovascular and overall health.

Sleep Problems Run In Families - A Challenge for Parental Behavior

This article discusses she most recent Sleep in America Poll which shows that sleep issues can run in families.

Let's model best sleep hygiene by turning off our electronic toys.  JR

The National Sleep Foundation has released its annual Sleep in America Poll. This year, the poll examines sleep in the modern American family. How well—or not—are parents and children sleeping today? What are the challenges facing families in their pursuit of high-quality, plentiful sleep? What are the strategies that parents are using to help their children sleep, and how well are those strategies working? These are some of the questions that this year’s sleep survey investigates. The answers paint a picture of American families needing more sleep than they are getting, and struggling to contend with challenges to sleep that are a product of technologically-driven and highly-scheduled lives.

The survey included 1,103 adults with at least one child between the ages 6-17 living in their households. Among respondents, 54% were mothers. The families surveyed varied in size: 40% of respondents had 2 children, 24% had 1 child, and another 24% had 3 children.  Eleven percent of respondents had 4 or more children in their households. Adults reported on their own sleep and answered sleep questions about their children.

The results indicate challenges to sleep within American families that are, in fact, distinctly modern. Despite a high level of awareness of the importance of sleep to health and well being, neither children nor their parents are getting enough high quality sleep. This appears to be in part because of a heavy rotation of evening activities and commitments for both adults and children. Technology has taken up residence in most bedrooms—parents’ and children’s—to the detriment of sleep for both. The survey also found that parents’ own behaviors about sleep, as well as their willingness to set rules for their children’s sleep, can have a significant effect on sleep within the family:

• There is broad consensus among parents about the importance of sleep to their family’s mental and physical health. More than 90% of parents reported their belief that sleep is highly important to the health and well being of both adults and children in their family.

• Despite this recognition about the importance of sleep, both children and their parents are struggling to get enough sleep, and to sleep well. Fewer than 45% of children between the ages 6-17 are sleeping 9 or more hours per night. Recommendations for sufficient sleep amounts for children vary by age, but at all stages of childhood and adolescence, children need at least 9 hours of sleep per night. Younger school-age children need in excess of 10-11 hours nightly.

• As children age, their nightly sleep shortens, according to these results. Among 12-14 years olds, less than a third were reported to be sleeping 9 hours a night. Among older adolescents ages 15-17, a majority—56%–were reported to be sleeping no more than 7 hours nightly.

• Researchers compared the amount of sleep to quality of sleep, and found that children who slept less also were more likely to experience lower quality sleep. Among children who slept fewer than 7 hours a night, more than a quarter—28%–were reported to have poor quality sleep.

• Parents tended to rate their children’s sleep quality as significantly better than their own. Only 13% of adults reported their sleep as excellent, compared to 42% who rated their children’s sleep this highly.

• When asked about the challenges they face in getting enough sleep for themselves and their children, parents cited busy schedules as the most common obstacle. Evening activities were the most frequently cited challenge, both for parents and for children. For children, homework was also often reported as a nightly obligation that delayed bedtime or otherwise made sleep more difficult.

A substantial majority of adults and children are sleeping in proximity to at least one or more electronic device, according to the survey results. Televisions, computers, tablets, smartphones, gaming and music devices are commonly found in children’s bedrooms as well as in their parents’:

• 89% of adults and 75% of children have at least 1 electronic device in their bedrooms. Roughly half of children—51%–and 68% of adults have 2 or more electronic devices in their bedrooms.

• Televisions are the most common electronic devices in both parents’ and children’s bedrooms. MP3 players, tablets and smartphones are also common in both.

• The results also indicate that these devices are frequently left on during the night, rather than turned off before bedtime.

Electronic devices pose serious hazards to sleep when they take up residence in the bedroom. These devices emit light that disrupts sleep cycles and alters sleep-related hormone levels. The noise and stimulation that they provide is counterproductive to sleep, pushing back bedtimes and risking waking during the night when they are left on. It’s not surprising, then, that the survey found children with electronic devices in their bedrooms slept less and experienced lower quality sleep than those children without these gadgets in their bedrooms. Sleep quality suffered most dramatically when the devices were regularly left on during the night. And the more devices were present, the worse children slept.

Despite the sleep problems associated with electronics in the bedroom, many adults and children use these devices as a means to fall asleep, according to the survey. Sixty-six percent of adults reported a habit of relying on television or videos to help them fall asleep, and 37% used the internet. Parents reported that their children often used these same tactics to help them sleep: 47% of children were reported to watch television to fall asleep with some regularity, and 27% played games or used the internet to help bring about sleep.

One of the more striking details about how technology is intruding on sleep? The prevalence of texting and emailing after initially falling asleep, among both children and their parents. More than one quarter of adults—26%–either read or sent emails and text messages after first falling asleep for the night, as did 16% of children. More than half of the children who texted and emailed during the night had parents who did so as well.

This points out another important finding from the survey: the influence of parents’ sleep -and-technology-related habits on their children’s own sleep behaviors. The results indicate that children with electronic devices in their bedrooms are significantly more likely to have parents’ who also have these devices in their bedrooms. Children who let their devices run during the night are also more likely to have parents who do the same.

Ready for some good news about parental influence on kids’ sleep? Parents who establish sleep-related rules and enforce them consistently report their children sleep longer and better than children whose parents don’t apply regular rules to bedtime. These rules include consistent bedtimes, and also govern before-bed activities like watching television, using phones, playing video games, and drinking soda with caffeine. Children in households with sleep rules that are routinely enforced sleep an average of 1.1 additional hours per night.

There are a lot of moving pieces in this picture of the American family’s sleep life—busy schedules, crowded and active evening hours, constant temptation from technology. These threats to high-quality and plentiful sleep are not going away—in fact, they’re more likely to proliferate. It is our modern-day challenge to find ways to manage these ever-present demands with balance and moderation—and with an eye on protecting sleep.

Middle aged women commonly have sleep disorders

A survey shows that about a quarter of middle-aged women have sleep issues and disorders.

Almost a quarter of middle-aged women report their quality of sleep is less than good, according to a new study.

Sleep problems were tied to poor quality of life, chronic illness and medication use, researchers found.

The new study adds to earlier research by looking at common sleep problems among women before they hit menopause, according to Dr. Päivi Polo. She led the study at the University of Turku in Finland.

"Typically we think that these are problems of menopause and thus menopause is the reason for everything," Polo told Reuters Health.

"Then we try to treat all menopausal insomnia symptoms with hormone replacement therapy ... but because in some women the sleep problems are already evident before the menopause, the HRT may not alleviate all sleep problems and we physicians are wondering what to do next."

After menopause, hot flashes and night sweats increase sleep problems, she said.

Polo and her colleagues surveyed 850 mothers about their sleep when they were 42 years old, on average. One third had a chronic illness, like diabetes or heart disease, and 28 percent were on regular medication.

Women most often reported waking up frequently at night. Sixty percent of them had that problem at least once a week.

Sixteen percent of women reported having difficulty falling asleep and 20 percent said they woke up too early in the morning on a weekly basis.

Morning sleepiness was reported by 42 percent and daytime sleepiness by 32 percent.

Sleep troubles are not new for people of any age, but they do seem to be a bit more common among women. Hormonal changes related to menstrual cycles or menopause may be partly to blame, the authors write in Maturitas.

Occasional alcohol drinking was tied to better sleep quality and less falling asleep at work, they found.

But women's weight and physical activity levels were not linked to sleep problems. That might be because most women in the study were in the normal range for body size, Polo said. Other studies have tied obesity to sleep problems like sleep apnea.

"There is likely a bidirectional association such that obesity may induce poor sleep, and short sleep may induce weight gain and subsequent obesity," Dr. Helen Driver, who researches sleep at Queen's University in Kingston, Ontario, Canada, said.

"The study was not designed to assess much detail about the relationship between physical activity and sleep, which is a complex interaction depending on factors such as physical fitness, aerobic capacity, exercise type (aerobic, non-aerobic, stretching) and timing," Driver told Reuters Health in an email.

All sleep problems can affect daytime tiredness, work performance and quality of life, Driver said.

Women tend to get about seven hours of sleep each night during the week, but sleep needs are unique to individuals, she said.

"Sleep is so crucial, since we sleep one third of our life and it affects so much of our health," Polo said. Sleep problems can be a symptom of a disease or mental state, which doctors should keep in mind, she said.

Women having sleep problems should talk to their doctor and be sure to note any potential sleep-related side effects of medications, researchers said.

"A good start is to keep a sleep diary and note any patterns or symptoms such as snoring, restlessness, morning headache," Driver said. "If there is concern ask your family physician for a referral to a sleep center for an assessment by a qualified sleep specialist."

Why is sleep so important to maintaining a healthy lifestyle?

This article discusses three studies, all which show how important sleep is in order to maintain a healthy lifestyle.

Three new studies show just how critical it is for adults to seek treatment for a sleep illness and aim for seven to nine hours of sleep each night in order to maintain a healthy lifestyle.

One study of 2,240 adults is the first to examine the link between obstructive sleep apnea (OSA) and mortality in Asians. Results show that all-cause mortality risk was 2.5 times higher and cardiovascular mortality risk was more than 4 times higher among people with severe OSA. The results are consistent with previous studies in the U.S. and other countries.

Another study of 2,673 patients in Australia found that untreated OSA is associated with an increased risk of motor vehicle crashes in very sleepy men as well as near-misses in men and women. Participants with untreated OSA reported crashes at a rate three times higher than the general community.

That last study examined the relationship between sleep duration and self-rated health in Korean adults. Results show that short sleep duration of 5 hours or less per day and long sleep duration of 9 hours or more per day was associated with poor self-rated health. The results add weight to recent data emphasizing the importance of adequate sleep in physical and mental health.

All three of the studies are in the Oct. 15 issue of the Journal of Clinical Sleep Medicine, which is published by the American Academy of Sleep Medicine.

The AASM reports that at least 12 to 18 million adults in the U.S. have untreated obstructive sleep apnea, which involves the repetitive collapse of the upper airway during sleep. OSA is a serious sleep illness that is associated with an increased risk of high blood pressure, heart disease, diabetes, depression and stroke. The most effective treatment option for OSA is CPAP therapy, which helps keep the airway open by providing a stream of air through a mask that is worn during sleep.

Most adults need about seven to eight hours of nightly sleep to feel alert and well rested. However, 30 percent of adults in the U.S. regularly get insufficient sleep.

Help for people who have OSA or another sleep problem is available from board certified sleep medicine physicians at more than 2,500 AASM accredited sleep disorders centers.

Smoking leads to sleeping issues

Research suggest that smoking can negatively influence sleep and result in sleeping issues and disturbances.

Smoking may interfere with a good night's sleep, a new study suggests.

Despite being well established as the leading cause of preventable death and a wide range of health problems, smoking's effects on sleep are little understood.

In an effort to fill this gap in knowledge, researchers from the University of Florida and Research Triangle Park examined the relationship between sleep difficulty and smoking status among a nationally representative sample.

Twelve percent of current smokers, they found, reported trouble falling asleep, while 10 percent complained of waking too early. An additional 11 percent, moreover, said they often woke during the night.

Insufficient sleep is associated with a wide range of health problems, including depression, diabetes and high blood sugar. As a result, the researchers hypothesize that smokers may be putting themselves at risk for much more than the commonly recognized health problems associated with smoking, such as cancer and cardiovascular disease.

In an effort to decrease smoking rates across the United States, government health officials launched an anti-smoking campaign last year using funding provided by the Affordable Care Act's Prevention and Public Health Fund. Called "Tips From Former Smokers," the campaign was designed to depict in graphic detail the effects of smoking.

According to a study released by the Centers for Disease Control (CDC), the campaign prompted more than 1.6 million Americans to try to quit, of which 200,000 succeeded. 

All told, the results far exceeded the campaign's original goals of 500,000 quit attempts and 50,000 successful quits.

"This is exciting news," CDC Director Dr. Tom Frieden said in a statement. "Quitting can be hard, and I congratulate and celebrate with former smokers -- this is the most important step you can take to a longer, healthier life."

According to the CDC, more than 1,200 people living in the United States die every day due to the effects of smoking.
