Honeybee Circadian Rhythms Are Affected More by Social Interactions

118613_web_1.jpg

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.

Researchers Find Possible Missing Link Between Sleep and Improved Memory

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.

Shorter Time in Bed May Protect Against Chronic Insomnia

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).

Weight and Diet May Help Predict Sleep Quality

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.

Implantable Device Cuts Obstructive Sleep Apnea Symptoms

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.

Need Better Sleep? Consider the Cognitive Shuffle

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).

Mapping Neural Networks to Strengthen Circadian Rhythms

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.

Telephone-Based Cognitive Behavioral Therapy Significantly Improves Menopause Symptoms

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.
