The 2013 Rx Sleep Survey, conducted by Harris Interactive on behalf of Targeted Medical Pharma, found the vast majority of Americans don’t get enough sleep. The telephone survey was conducted by Harris between April 25 and 28 among 1,008 U.S. adults 18 years of age and older. Results were weighted for age, sex, geographic region and race when necessary to align them with their actual proportions in the population.
Disrupted sleep is so commonly a symptom of depression that some of the first things doctors look for in diagnosing depression are insomnia and excessive sleeping. Now, however, scientists have observed for the first time a dysfunctional body clock in the brains of people with depression.
Scientists from the University of Tubingen, Germany, have discovered a technique to improve both sleep and memory at the same time by playing sound waves attuned to the frequencies of the brain's oscillations, according to a study published in the journal Neuron.
