New Evidence Of Age-Related Decline In The Brain’s Master Circadian Clock

A new study of the brain's master circadian clock -- known as the suprachiasmatic nucleus, or SCN -- reveals that a key pattern of rhythmic neural activity begins to decline by middle age. The study, whose senior author is UCLA Chancellor Gene Block, may have implications for the large number of older people who have difficulty sleeping and adjusting to time changes.

Wakeup Call For College Students: New Research Finds You Need To...

University of Cincinnati research finds that college students could be undermining their own education, simply because they're not practicing proper sleep habits. The study, led by Adam Knowlden, a UC doctoral student in UC's Health Promotion and Education Program, also holds recommendations for students to form better sleep habits that will ultimately enhance their learning.

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.

Secrets Of The ‘Sleep Hormone’: Discovery Leads To Novel Melatonin Drug...

A team from the Research Institute of the McGill University Health Centre (RI-MUHC) and McGill University has made a major breakthrough by unraveling the inner workings of melatonin, also known as the "sleep hormone." The research, conducted in collaboration with scientists in Italy,...

Mid-Afternoon Slump? Why A Sugar Rush May Not Be The Answer

Protein -- not sugar -- stimulates cells keeping us thin and awake, a new study suggests. A new study has found that protein and not sugar activates the cells responsible for keeping us awake and burning calories. The research, published in the Nov. 17 issue of the scientific journal Neuron, has...

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.

Higher Death Risk With Sleeping Pills

People are relying on sleeping pills more than ever to get a good night's rest, but a new study by Scripps Clinic researchers links the medications to a 4.6 times higher risk of death and a significant increase in cancer cases among regular pill users.

The Longer You’re Awake, The Slower You Get

Anyone that has ever had trouble sleeping can attest to the difficulties at work the following day. Experts recommend eight hours of sleep per night for ideal health and productivity, but what if five to six hours of sleep is your norm? Is your work still negatively affected? A team of researchers at Brigham and Women's Hospital (BWH) have discovered that regardless of how tired you perceive yourself to be, that lack of sleep can influence the way you perform certain tasks.

Light From Self-Luminous Tablet Computers Can Affect Evening Melatonin, Delaying Sleep

A new study from the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute shows that a two-hour exposure to electronic devices with self-luminous "backlit" displays causes melatonin suppression, which might lead to delayed bedtimes, especially in teens.

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.

Adequate Sleep Helps Weight Loss

Adequate sleep is an important part of a weight loss plan and should be added to the recommended mix of diet and exercise, states a commentary in CMAJ (Canadian Medical Association Journal).

Antidepressants, Sleeping Pills And Anxiety Drugs May Increase Driving Risk

Drugs prescribed to treat anxiety, depression and insomnia may increase patients' risk of being involved in motor vehicle accidents, according to a recent study, published in the British Journal of Clinical Pharmacology. Based on the findings, the researchers suggested doctors should consider advising patients not to drive while taking these drugs.
