Japanese researchers centered at Nagoya University reveal a role for orexin neurons of the hypothalamus when mice respond to painful stimuli, and suggest a link between stimulus response and consciousness.
Preschoolers who are regularly tucked into bed by 8 p.m. are far less likely to become obese teenagers than young children who go to sleep later in the evening, new research has found. Bedtimes after 9 p.m. appeared to double the likelihood of obesity later in life.
Men who sleep either fewer or more hours than average may face a greater risk of developing diabetes, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.
Teaching parents bedtime techniques to encourage healthy sleep habits in their infants may help prevent obesity, according to Penn State College of Medicine researchers. Strong links exist between inadequate sleep and childhood obesity.
Circadian rhythms are internal clocks that determine many of an organism's daily rhythms, for example sleep-wake, feeding, urinary output and hormone production. Aligned with the environment by external forces such as sunlight and ambient temperature, circadian rhythms are important for animal health and survival. Disturbances of the circadian clock are associated with a variety of diseases in humans and animals, including cancer, mental illnesses and metabolic disorders, such as diabetes and obesity.
People with multiple sclerosis often have trouble with memory, attention and mental processing. New research shows some of these issues could stem from sleep disorders.
While it’s important for children of all ages to embrace the down time away from the high expectations and heavy workloads of being in school, summer is not necessarily the time to abandon a structured schedule and learning opportunities. Here are a few tips for families to follow to help make this summer season productive and enjoyable.
A new study found that the NFL, NBA and NHL teams traveling from west to east had a higher winning percentage compared to teams traveling in the opposite direction.
A team of sleep researchers at the University of California, Riverside, led by psychology professor Sara C. Mednick, has found that the autonomic nervous system, which is responsible for control of bodily functions not consciously directed (such as breathing, heartbeat, and digestive processes) plays a role in promoting memory consolidation – the process of converting information from short-term to long-term memory – during sleep.
For the first time, the American Academy of Sleep Medicine (AASM) has released official consensus recommendations for the amount of sleep needed to promote optimal health in children and teenagers to avoid the health risks of insufficient sleep.
Preliminary findings from a Penn Medicine study (abstract #0508) presented at SLEEP 2016, the 30th annual meeting of the Associated Professional Sleep Societies LLC, suggest that what may prevent 70 to 80 percent of individuals with new onset insomnia (acute insomnia) from developing chronic insomnia is a natural tendency to self-restrict time in bed (TIB).
The old adage “you are what you eat,” may be better phrased as “your sleep relates to what you eat.” An individual’s body composition and caloric intake can influence time spent in specific sleep stages, according to results of a new study (abstract 0088) from researchers at the Perelman School of Medicine at the University of Pennsylvania that will be presented at SLEEP 2016, the 30th annual meeting of the Associated Professional Sleep Societies LLC.
Since the 1980s, continuous positive airway pressure (CPAP) – in which positive pressure is pushed through the nasal airways to help users breathe while sleeping – has been by far the most widely used treatment for obstructive sleep apnea (OSA). With more than 18 million people experiencing OSA, a number expected to rise, new results from a Penn case study of a new device implanted in the chest called hypoglossal nerve stimulation (HGNS) offers promise for patients with moderate to severe OSA who cannot tolerate CPAP. Researchers at the Perelman School of Medicine at the University of Pennsylvania will present data (abstract 0378) on their outcomes with hypoglossal nerve stimulation for the treatment of patients with sleep apnea at SLEEP 2016, the 30th annual meeting of the Associated Professional Sleep Societies LLC.
Simon Fraser University research aimed at helping people get to sleep will be highlighted at an international sleep conference next week. Luc Beaudoin, an adjunct professor in cognitive science and education, created the mySleepButton® app two years ago (a new version with the world's first configurable "body scan" will be released shortly).
The amino acid acetylcarnitine may help predict an individual’s neurobehavioral performance during chronic sleep restriction, according to results of a new study (abstract 0251) from researchers at the Perelman School of Medicine at the University of Pennsylvania that will be presented at SLEEP 2016, the 30th annual meeting of the Associated Professional Sleep Societies LLC.

While the evidence behind this age-related weakening of the circadian rhythm has been established in medical literature, the mechanisms behind it, and the connectivity structure of the neurons, have remained elusive. To better understand these neuronal and hormonal mechanisms and help develop potential treatments, researchers have conducted experimental analyses of the SCN’s connections, with the goal of determining its degree of heterogeneity. They discuss their work in this week’s CHAOS.
Researchers are making progress in understanding exactly how sleep helps the brain lay down memories and remove waste products. The findings may have implications for diseases in which sleep and memory are impaired. Alzforum reports.
Chatting on the phone with a “sleep coach” and keeping a nightly sleep diary significantly improve sleep quality and reduce insomnia in women through all stages of menopause, according to a new study published in JAMA Internal Medicine. The study also found that such phone-based cognitive behavioral therapy significantly reduced the degree to which hot flashes interfered with daily functioning.
