New research in the FASEB Journal demonstrates role of IL-6 on sleep-related consolidation of specific types of memories, particularly during late night REM sleep cycles Good news for procrastinating students: a nasal spray developed by a team of German scientists promises to give late night cram sessions a major boost, if a good night's sleep follows. In a research report featured as the cover story of the October 2009 print issue of The FASEB Journal, these scientists show that a molecule...

The study is the first to show that the impact of alcoholism on sleep is similar in both men and women A study in the Oct.1 issue of the journal Sleep shows that long-term alcoholism affects sleep even after long periods of abstinence, and the pattern of this effect is similar in both men and women. Results indicate that in long-term alcoholics who had not had a drink for up to 719 days, the percentage of slow wave sleep was significantly lower (6.6% in men, 11.1% in women) than in controls...

Experts in sleep studies presented evidence that showed poor quality sleep - whether from insomnia, sleep fragmentation, or nightmares - is associated with increased risk of death, Reuters reported. The results came from several presentations last week in Seattle at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies. One study suggested that insomnia might be as hazardous as obstructive sleep apnea, according to researchers at Penn State College of Medicine in...

This study is the first to examine the relationship between obstructive sleep apnea and type 2 diabetes in a predominantly African-American and Hispanic populationA multi-ethnic study in the June 15 issue of the Journal of Clinical Sleep Medicine reports that there is a statistically significant relationship between obstructive sleep apnea (OSA) episodes occurring during rapid eye movement (REM) sleep and type 2 diabetes.Results indicate that the adjusted odds ratio for type 2 diabetes was...

Good sleep habits that translate into getting a good night's sleep may pay off with a lower mortality risk, U.S. researchers said. The eight-year study based on 5,614 Sleep Heart Health Study participants found two sleep-stage transition types associated with higher mortality risk. In light of this growing body of evidence, people should strive to maintain good sleep habits, such as going to bed and getting up at the same time each day and sleeping for seven to eight hours each night, lead...

Naps with rapid eye movement (REM) sleep refresh the brain's empathetic sensitivity for evaluating human emotions by decreasing a negative bias and amplifying recognition of positive emotions, according to a research abstract that will be presented on Wednesday, June 10, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies.Results show that the emotional brain is not stable across the day, resulting in marked changes in emotional reactivity. Naps with REM...

Jet lag is the bane of many travelers, and similar fatigue can plague people who work in rotating shifts. Scientists know the problem results from disruption to the body's normal rhythms and are getting closer to a better understanding that might lead to more effective treatment. New University of Washington research shows the disruption occurs in two separate but linked groups of neurons in a structure called the suprachiasmatic nucleus, below the hypothalamus at the base of the brain. One...

 Sleep is such an essential part of human existence that we spend about a third of our lives doing it -- some more successfully than others. Sleep disorders afflict some 50-70 million people in the United States and are a major cause of disease and injury. People who suffer from disturbed sleep have an increased risk of heart attack, stroke, hypertension, obesity, depression, and accidents. Nearly a fifth of all serious car crashes, in fact, are linked to sleeplessness.Diagnosing sleep...

German scientists say they've discovered very immature sheep fetuses can enter a dreaming sleep-like state weeks before rapid eye movements develop. The Friedrich Schiller University researchers in Jena, Germany, led by mathematician Karin Schwab noted that after about seven months growing in the womb, a human fetus spends most of its time asleep. Its brain cycles between rapid eye movement sleep and the quiet resting state of non-REM sleep. But whether the brains of younger, immature fetuses...

New research in AIP's journal Chaos reveals sleep cycles in early fetus After about seven months growing in the womb, a human fetus spends most of its time asleep. Its brain cycles back and forth between the frenzied activity of rapid eye movement (REM) sleep and the quiet resting state of non-REM sleep. But whether the brains of younger, immature fetuses cycle with sleep or are simply inactive has remained a mystery, until now. Mathematician Karin Schwab and a team of neuroscientists at...
