Cortex-wide variation of neuronal cellular energy levels depending on the sleep-wake states
The brain is assumed to exert homeostatic functions to always keep the cellular energy status constant, this has not been proven. Researchers at Tokyo Metropolitan Institute of Medical Science discovered that cortical neuronal intracellular concentrations of ATP, the major cellular energy metabolite, greatly decreased during REM sleep, despite a simultaneous increase in cerebral hemodynamics for energy supply, compared with waking in mice. These indicate that cerebral energy metabolism may not always meet neuronal energy demands. (2020-10-07)

'I'll sleep when I'm dead': The sleep-deprived masculinity stereotype
In the United States, the average American sleeps less than the minimum seven hours of sleep per night recommended by the Center for Disease Control, and nearly half of Americans report negative consequences from insufficient sleep. This problem appears to be especially prevalent in men, who report getting significantly less sleep, on average, than women. (2020-09-29)

Childhood and adult trauma create sleepless nights for midlife women
Sleep disturbances are often reported by postmenopausal women. A new study reports just how prevalent those sleep problems are and that women who endured trauma as children or adults are more likely to suffer poor-quality sleep. Study results will be presented during the 2020 virtual Annual Meeting of The North American Menopause Society (NAMS), which opens on September 28. (2020-09-28)

Research confirms link between sleep apnea and Alzheimer's disease
New research shows damage in the brain starts in the same place and spreads in the same way in sleep apnea, as in Alzheimer's disease. The study is the first to find Alzheimer's-like amyloid plaques in the brains of people with clinically-verified obstructive sleep apnea, a condition that affects more than 936 million people worldwide. (2020-09-28)

Twinkling, star-shaped brain cells may hold the key to why, how we sleep
A new study published today in the journal Current Biology suggests that star-shaped brain cells known as astrocytes could be as important to the regulation of sleep as neurons. The study builds new momentum toward ultimately solving the mystery of why we sleep and how sleep works in the brain. The discovery may also set the stage for potential future treatment strategies for sleep disorders and neurological diseases and other conditions associated with troubled sleep. (2020-09-24)

Loneliness levels high during COVID-19 lockdown
During the initial phase of COVID-19 lockdown, rates of loneliness among people in the UK were high and were associated with a number of social and health factors, according to a new study published this week in the open-access journal PLOS ONE by Jenny Groarke of Queen's University Belfast, UK, and colleagues. (2020-09-24)

Don't sleep on the hypnotic potential of thalidomide
Researchers from the University of Tsukuba identified a novel molecular pathway for the hypnotic effects of thalidomide. By comparing the effects of thalidomide on the sleep of normal mice and mice in which the protein cereblon was resistant to thalidomide, the researchers found that thalidomide acted independently of cereblon but similarly to general anesthetics and sedatives to induce sleep. These findings could help develop thalidomide-like hypnotic drugs without its teratogenic effects. (2020-09-23)

Insomnia treatment offers relief
Insomnia causing sleepless nights, daytime fatigue and poor health outcomes is a cycle worth busting, experts say, with depression, anxiety and stress a common co-occurrence. A study of more than 450 insomnia patients in Australia has confirmed some positive results for such patients with insomnia. (2020-09-23)

Study finds gut microbiome plays important role in sleep regulation
Obstructive sleep apnea (OSA) affects more than one billion people worldwide. Evidence suggests OSA can alter the gut microbiome (GM) and may promote OSA-associated co-morbidities, including diabetes, hypertension and cognitive problems. Researchers from the University of Missouri School of Medicine have discovered how OSA-related sleep disturbances affect the gut microbiome in mice and how transplanting those gut bacteria into other mice can cause changes to sleep patterns in the recipient mice. (2020-09-23)

Early birds vs night owls: for diabetics, an early bedtime is best
Early to bed, early to rise...while the old saying promises health, wealth and wisdom, new research confirms part of the adage holds true, as a world first study shows that people who go to bed early are more likely to be in better health and more physically active compared to night owls. (2020-09-20)

Size and sleep: New research reveals why little things sleep longer
Using data from humans and other mammals, a team of scientists including researchers from the Santa Fe Institute has developed one of the first quantitative models that explains why sleep times across species and during development decrease as brains get bigger. Crucially, the model identifies a sharp transition at around 2.4 years of age, where sleep patterns change in humans as the primary purpose of sleep shifts from reorganization, which is essentially learning, to repair. (2020-09-18)

UCLA-led team of scientists discovers why we need sleep

Reduction in insomnia symptoms associated with non-invasive neurotechnology
For people with chronic insomnia, a good night's sleep is elusive. But what if insomnia symptoms could be alleviated by simply listening to one's own brainwaves? (2020-09-17)

People react better to both negative and positive events with more sleep
New research from UBC finds that after a night of shorter sleep, people react more emotionally to stressful events the next day--and they don't find as much joy in the good things. This has important health implications: previous research shows that being unable to maintain positive emotions in the face of stress puts people at risk of inflammation and even an earlier death. (2020-09-15)

COVID-19 patients with sleep apnoea could be at additional risk
People who have been diagnosed with obstructive sleep apnoea could be at increased risk of adverse outcomes from COVID-19 according to a new study from the University of Warwick. (2020-09-14)

Measuring brainwaves while sleeping can tell if you should switch antidepressants
Scientists have discovered that measuring brainwaves produced during REM sleep can predict whether a patient will respond to treatment from depression. This enables patients to switch to a new treatment rather than continue the ineffective treatment (and the depression) for weeks without knowing the outcome. (2020-09-12)

Sleep apnea linked with higher spine fracture risk among women
Emerging evidence suggests that obstructive sleep apnea (OSA) may negatively affect bone health. Results from a new study published in the Journal of Bone and Mineral Research now indicate that women with history of OSA may face a higher risk of spine, or vertebral, fractures. (2020-09-10)

Monitoring sleep positions for a healthy rest
MIT researchers have developed a wireless, private way to monitor a person's sleep postures -- whether snoozing on their back, stomach, or sides -- using reflected radio signals from a small device mounted on a bedroom wall. (2020-09-10)

The neurons that connect stress, insomnia, and the immune system
Researchers have pinpointed the circuit in the brain that is responsible for sleepless nights in times of stress--and it turns out that circuit does more than make you toss and turn. Their study, done in mice, ties the same neuronal connections that trigger insomnia to a stress-induced weakening of the immune system. (2020-09-09)

Relief for people who struggle with CPAP masks
A trial of a simple yet effective surgery has led Australian experts to promote it as an option to specialists around the world for managing difficult obstructive sleep apnoea (OSA) cases. After rigorous evaluation of the surgery, excellent outcomes were shown in sleep apnea patients who had been unable to use continuous positive pressure airway (CPAP) treatment, with patients achieved relief from snoring and disrupted sleep and experienced improved general health. according to a new report in the Journal of the American Medical Association (JAMA). (2020-09-04)

Researchers probe Soldier sleep deprivation effects
New Army-funded study looks at effects of sleep deprivation, which can greatly affect Soldiers on the battlefield. Research conducted at the University of Rochester Medical Center and funded by the Army Research Office, an element of the U.S. Army Combat Capabilities Development Command's Army Research Laboratory, suggests that people who rely on sleeping during daytime hours are at greater risk for developing neurological disorders. (2020-09-03)

How we sleep today may forecast when Alzheimer's disease begins
UC Berkeley neuroscientists have found a way to estimate, with some degree of accuracy, a time frame for when Alzheimer's is most likely to strike in a person's lifetime, based on their baseline sleep patterns. Their findings suggest one defense against this virulent form of dementia -- for which no treatment currently exists -- is deep, restorative sleep, and plenty of it. (2020-09-03)

Study in half a million adults with overweight or obesity suggests benefit of weight loss on serious health problems
People with obesity who intentionally (not because of illness) lost an average (median) 13% of their initial body weight reduced their relative risk of developing type 2 diabetes by 42%-44%, sleep apnoea by 22%-27%, high blood pressure by 18%-25%, and dyslipidaemia (unusually high levels of cholesterol and other fats in the blood) by 20-22%, according to a study of over 550,000 adults in primary care in the UK. (2020-09-03)

Circadian rhythms help guide waste from brain
New research details how the complex set of molecular and fluid dynamics that comprise the glymphatic system - the brain's unique process of waste removal - are synchronized with the master internal clock that regulates the sleep-wake cycle. These findings suggest that people who rely on sleeping during daytime hours are at greater risk for developing neurological disorders. (2020-09-02)

UIC research discovers links among poor sleep, high blood pressure, gut microbiome
University of Illinois Chicago researchers have found associations among disrupted sleep, elevated blood pressure and changes in the gut microbiome.The research aimed to determine whether a 28-day period of disrupted sleep changed the microbiota in rats.
