Lee Rannals for redOrbit.com - Your Universe Online Trying to recoup some lost sleep from the crazy work week on the weekend isn't as effective as one might think, according to findings reported in the American Journal of Physiology. A few days of lost sleep can have adverse side effects, such as increased daytime sleepiness, worsened daytime performance, an increase in molecules that are a sign of inflammation in the body, and impaired blood sugar regulation. Although many people...

People sleep significantly better and feel more alert during the day if they get at least 150 minutes of exercise a week, a new study concludes. A nationally representative sample of more than 2,600 men and women, ages 18-85, found that 150 minutes of moderate to vigorous activity a week, which is the national guideline, provided a 65 percent improvement in sleep quality. People also said they felt less sleepy during the day, compared to those with less physical activity. The study, out...

The findings show that missing a night of sleep burns roughly 135 calories, the equivalent of two slices of bread or a 225 ml glass of semi-skimmed milk. In terms of physical exertion, this amounts to walking just under two miles. On the flip side, eight hours of sleep saved the same approximate amount of energy. 'While the amount of energy saved during sleep may seem small, it was actually more than we expected,' says Professor Kenneth Wright, lead author of the study and Director of...

(Ivanhoe Newswire) -- Have you ever wondered how some people go about their busy days on only 4 hours of sleep while others need at least 8 to function? This study suggests that genes may play a role in how the amount of sleep we get affects us. The study examined people who have a gene variant that is closely associated with narcolepsy, a sleep disorder that causes excessive daytime sleepiness. Having the gene variant, called DQB1*0602, doesn't mean that a person will develop narcolepsy....

Chronic sleep deprivation in a mouse model of Alzheimer's disease makes Alzheimer's brain plaques appear earlier and more often, researchers at Washington University School of Medicine in St. Louis report online this week in Science Express. They also found that orexin, a protein that helps regulate the sleep cycle, appears to be directly involved in the increase. Neurodegenerative disorders like Alzheimer's disease and Parkinson's disease often disrupt sleep. The new findings are some of the...

Worsening sleep quality over a five-year period is significantly associated with poorer mental quality of life, U.S. researchers say. Lead author Graciela E. Silva of Arizona State University said the study also found increasing daytime sleepiness symptoms were associated with both poorer physical and mental quality of life. The study obtained polysomnographic -- recordings of biophysiological changes that occur during sleep -- and clinical data from 3,078 patients included in the baseline...

People who say they are addicted to playing video games sleep less but generally don't recognize their pastime could be responsible, U.S. researchers found. Amanda Woolems of the University of Arkansas in Little Rock says previous research had shown excessive gamers spend less time in bed, have longer sleep latency and shorter REM latency. Our statistics revealed that those who admitted addiction scored higher on the Epworth Sleepiness Scale -- sleepiness, Woolems said in a statement. It...

 According to a research abstract that will be presented on Monday, June 8, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, television watching may be an important determinant of bedtime, and may contribute to chronic sleep debt.The study included data from 21,475 people aged 15 or older who completed the American Time Use Survey between the years 2003 and 2006. The study examined the activities participants undertook two hours before and after bed...

A new study could change the way doctors administer certain sleep tests. It looked at protocol used for detecting excessive daytime sleepiness (EDS) in adults who may fall asleep while driving. Researchers found a 40-minute protocol to be more effective than a 20-minute interval.  The study showed more people actually fell asleep during the longer duration.  Results also suggest  the test may not be completely reliable when the strong motivation to keep a driver's license...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
