  • Marijuana use can affect sleep quality

    Jun 11 2014...
    A new study suggests that marijuana use is associated with impaired sleep quality.

    Results show that any history of cannabis use was associated with an increased likelihood of reporting difficulty falling asleep and struggling to maintain sleep. Participants also reported experiencing non-restorative sleep and feeling daytime sleepiness. READ MORE>>

  • Sleep helps boost production of brain cells

    Sep 05 2013...
    A new study finds yet another reason to get more sleep – it’s beneficial for the brain. Sleep increases the reproduction of the cells that go on to form the insulating material on nerve cell projections in the brain and spinal cord known as myelin, according to an animal study published in the September 4 issue of The Journal of Neuroscience. The findings could one day lead scientists to new insights about sleep's role in brain repair and growth.

    Scientists have known for years that many genes are turned on during sleep and off during periods of wakefulness. However, it was unclear how sleep affects specific cells types, such as oligodendrocytes, which make myelin in the healthy brain and in response to injury. Much like the insulation around an electrical wire, myelin allows electrical impulses to move rapidly from one cell to the next. READ MORE>>
  • Sleep apnea may increase risk of blindness

    Aug 09 2013...
    Countless studies have linked sleep apnea to severe health consequences such as high blood pressure and heart disease. A new study now suggests screening sleep apnea sufferers for glaucoma. Researchers in Taiwan have discovered that people with sleep apnea are far more likely to develop glaucoma compared to those without the sleep condition.

    "We hope that this study encourages clinicians to alert obstructive sleep apnea patients of the associations between obstructive sleep apnea and open-angle glaucoma as a means of raising the issue and encouraging treatment of those who need it," wrote the authors of the study, led by Herng-Ching Lin, Ph.D., of the College of Medical Science and Technology at Taipei Medical University.

  • Study links diabetes risk to melatonin levels

    Apr 03 2013...
    Millions of Americans are diagnosed with type 2 diabetes, yet the exact causes of diabetes still puzzle scientists. Now, new research from Brigham and Women's Hospital (BWH) finds that the amount of melatonin a person secretes during sleep may predict their risk of developing type 2 diabetes.

    "This is the first time that an independent association has been established between nocturnal melatonin secretion and type 2 diabetes risk," said Dr. Ciaran McMullan, a researcher in the Renal Division and Kidney Clinical Research Institute at BWH. "Hopefully this study will prompt future research to examine what influences a person's melatonin secretion and what is melatonin's role in altering a person's glucose metabolism and risk of diabetes."

  • Internal clocks can be ticking time bombs for diabetes, obesity

    Apr 01 2013...
    If you're pulling and all-nighter to finish a term paper, a new parent up all night with a fussy baby, or simply can't sleep like you once could, then you may be snoozing on good health. That's because new research published in The Federation of American Societies for Experimental Biology (FASEB) Journal used mice to show that proper sleep patterns are critical for healthy metabolic function, and even mild impairment in our circadian rhythms can lead to serious health consequences, including diabetes and obesity.

    "We should acknowledge the unforeseen importance of our 24-hour rhythms for health," said Claudia Coomans, Ph.D., a researcher involved in the work from the Department of Molecular Cell Biology in the Laboratory of Neurophysiology at Leiden University Medical Center in Leiden, Netherlands. "To quote Seneca 'We should live according to nature (secundum naturam vivere).'" READ MORE>>
  • Sleep loss precedes symptoms of Alzheimer’s disease

    Mar 12 2013...
    A new study out of Washington University School of Medicine in St. Louis finds that sleep is disrupted in people who likely have early Alzheimer's disease but do not yet have the memory loss or other cognitive problems characteristic of full-blown disease.

    "This link may provide us with an easily detectable sign of Alzheimer's pathology," says senior author David M. Holtzman, MD, the Andrew B. and Gretchen P. Jones Professor and head of Washington University's Department of Neurology. "As we start to treat people who have markers of early Alzheimer's, changes in sleep in response to treatments may serve as an indicator of whether the new treatments are succeeding." READ MORE>>
  • Sleep in America 2013: Sleep & Exercise

    Mar 04 2013...
    While exercise can be an important contributor to your sleep health, a growing body of research suggests that you don’t need a high intensity, grueling workout to sleep better. Even small amounts of routine physical activity may improve your sleep and overall well-being.

    This is good news for the many Americans who are failing to exercise regularly. According to the CDC, about 25 percent of U.S. adults report no leisure-time physical activity. READ MORE>>
  • Sleep deprivation disrupts genes

    Mar 01 2013...
    A new study found that as little as one week of sleep deprivation is enough to alter the activity of hundreds of human genes.

    The study, appearing in the journal PNAS, involved a small group of 26 participants who were exposed to one week of insufficient sleep (5.7 hours) and one week of sufficient sleep (8.5 hours). After each seven day period, the researchers collected and looked at blood samples that included ribonucleic acid (RNA), which transmits genetic information from DNA to proteins produced by cells.
