The nose knows when you’re tired. Sleep deprivation seems to increase the brain’s sensitivity to food smells, researchers reported at the Cognitive Neuroscience Society’s annual meeting in San Francisco.
Sleep deprivation and sleep disorders are dangerous, costly, and impact our health and overall well-being. New research puts forth sleep as a major public health concern, and shows that the effects of a good night's sleep are as beneficial for our happiness and well-being as winning the lottery might be.
Despite decades of warnings from the ‘Back to Sleep’ campaign, many parents are still putting their babies to sleep in ways that raise the risk of sudden infant death syndrome (SIDS), a new study found.
Sleep restores us. And not getting enough of it can put us at greater risk of heart disease and cancer. Sleep even makes us smarter. Yet researchers are finding that more than 10 percent of the population is chronically sleep deprived.
We all know the symptoms that result from running on five hours of sleep (or even less) for a few nights: Our brains feel foggy, thought processes become impaired, and sometimes we feel more anxious than usual. While the most obvious effects of sleep deprivation include feelings of fatigue or lowered productivity, long-term lack of sleep can take a toll on our bodies in often invisible ways.
The old adage about sleeping with one eye open in an unfamiliar place may not be too far off the mark. A new study suggests that one half of the brain remains on high alert during the first night of sleep in a new space, Reuters reported.
