Connections Between Circadian And Metabolic Systems Described

A paper by University of Notre Dame biologist Giles Duffield and a team of researchers offers new insights into a gene that plays a key role in modulating the body's circadian system and may also simultaneously modulate its metabolic system. The relationship between circadian and metabolic systems the researchers describe could have important implications for understanding the higher incidence of cardiovascular disease, obesity and diabetes among...

Older People Advised That Taking An Afternoon Nap Can Lead To...

Experts at the University of Surrey discovered that many older people felt that they may be branded lazy for taking afternoon naps so they tried hard to avoid nodding off. But the occasional nap can make older people more able to lead a fully active life by giving them enough energy to take part in recreational and social activities.

Dreaming Takes The Sting Out Of Painful Memories, Research Shows

They say time heals all wounds, and new research from the University of California, Berkeley, indicates that time spent in dream sleep can help us overcome painful ordeals. UC Berkeley researchers have found that during the dream phase of sleep, also known as REM sleep, our stress chemistry shuts down and the brain processes emotional experiences and takes the edge off difficult memories.

Possible Link Between Sleep-Disordered Breathing And Cardiovascular Disease Revealed

Doctors have long known that snoring is hazardous to health for a number of reasons. In addition to restless nights and increased daytime sleepiness, sleep-disordered breathing (SDB) has a series of associated health problems, including increased risk of cardiovascular disease (CVD).

Room Light Before Bedtime May Impact Sleep Quality, Blood Pressure And...

According to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM), exposure to electrical light between dusk and bedtime strongly suppresses melatonin levels and may impact physiologic processes regulated by melatonin signaling, such as sleepiness, thermoregulation, blood pressure and glucose homeostasis.

Body Clock Receptor Linked To Diabetes In New Genetic Study

A study recently published in Nature Genetics has found new evidence for a link between the body clock hormone melatonin and type 2 diabetes. The study found that people who carry rare genetic mutations in the receptor for melatonin have a much higher risk of type 2 diabetes.

Research Identifies The Herbal Supplements That Are Effective In Treating Anxiety

A systematic review of research into the use of nutritional supplements for the treatment of anxiety disorders has found strong evidence for the use of extracts of passionflower or kava and combinations of L-lysine and L-arginine.

Obstructive Sleep Apnea Linked to Blood Vessel Abnormalities

Obstructive sleep apnea may cause changes in blood vessel function that reduces blood supply to the heart in people who are otherwise healthy, according...

Sleep Makes Your Memories Stronger, And Helps With Creativity

As humans, we spend about a third of our lives asleep. So there must be a point to it, right? Scientists have found that sleep helps consolidate memories, fixing them in the brain so we can retrieve them later. Now, new research is showing that sleep also seems to reorganize memories, picking out the emotional details and reconfiguring the memories to help you produce new and creative ideas, according to the authors of an article in Current Directions in Psychological Science.

Brain’s Energy Restored During Sleep, Suggests Animal Study

In the initial stages of sleep, energy levels increase dramatically in brain regions found to be active during waking hours, according to new research in the June 30 issue of the Journal of Neuroscience.

Room Light Before Bedtime May Impact Sleep Quality, Blood Pressure And...

According to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM), exposure to electrical light between dusk and bedtime strongly suppresses melatonin levels and may impact physiologic processes regulated by melatonin signaling, such as sleepiness, thermoregulation, blood pressure and glucose homeostasis.

Popular Sleep Medicine Puts Older Adults At Risk For Falls, Cognitive...

Adults who take one of the world's most commonly prescribed sleep medications are significantly more at risk for nighttime falls and potential injury, according to a new study by the University of Colorado at Boulder.
