FRIDAY, March 31, 2017 -- More worrisome news for people who toss and turn all night: Insomnia appears to be linked to a heightened risk for heart attack or stroke, a research review from China suggests.
"We found that difficulty initiating sleep, difficulty maintaining sleep, or non-restorative sleep were associated with 27 percent, 11 percent, and 18 percent higher risks of cardiovascular and stroke events, respectively," said study co-author Qiao He.
WEDNESDAY, March 1, 2017 -- If you take melatonin supplements to help you nod off, take note: Many brands are inaccurately labeled, containing much less -- or much more -- of the sleep hormone than indicated, a new study reports.
What's more, a laboratory analysis found that eight of 31 melatonin supplements contained significant quantities of the drug serotonin, which is used to treat neurological disorders, the researchers said.
TUESDAY, Feb. 28, 2017 -- When it comes to sleeping pill prescriptions, doctors often stick to the same old routine, a new study suggests.
"Our results illuminate the notion that just as everyone else, many physicians are creatures of habit who tend to rely on cognitive shortcuts in their decision-making," said study first author Andrew Beam. He's a postdoctoral researcher at Harvard Medical School's department of biomedical informatics in Boston.
WEDNESDAY, Feb. 22, 2017 -- Seniors who begin sleeping more than nine hours a night may face a higher risk of dementia down the road, a new study suggests.
The researchers estimated that the risk of dementia grew by almost 2.5 times for those who found themselves recently needing extra sleep. The chances of dementia rose sixfold for people without a high school degree who suddenly needed to sleep nine hours or more, the study contended.
