April Flowers for redOrbit.com - Your Universe Online In an attempt to simulate a 520-day space mission to Mars, researchers in a groundbreaking new study lead by the Perelman School of Medicine at the University of Pennsylvania and the Baylor College of Medicine, have analyzed data on the impact of prolonged operational confinement on sleep, performance, and mood in astronauts. This new study, published online in the Proceedings of the National Academy of Sciences, demonstrates...

A new study shows that both length of time and percentage of overall sleep spent in different sleep stages are associated with decreased metabolic rate, increased hunger, and increased intake of calories (specifically from fat and carbohydrates). The findings suggest an explanation for the association between sleep problems and obesity. Researchers from St. Luke's-Roosevelt Hospital and Columbia University investigated the effects of sleep architecture on hunger to determine whether...

When Thomas Edison tested the first light bulb in 1879, he could never have imagined that his invention could one day contribute to a global obesity epidemic. Electric light allows us to work, rest and play at all hours of the day, and a paper published this week in Bioessays suggests that this might have serious consequences for our health and for our waistlines. Daily or "circadian" rhythms including the sleep wake cycle, and rhythms in hormone release are controlled by a molecular clock...

It's no secret that long-distance, west-to-east air travel — Seattle to Paris, for example — can raise havoc with a person's sleep and waking patterns, and that the effects are substantially less pronounced when traveling in the opposite direction. Now researchers, including a University of Washington biologist, have found hints that differing molecular processes in an area of the brain known as the suprachiasmatic nucleus might play a significant role in those jet lag...

As many as 25 percent of hospital nurses go without sleep for up to 24 hours in order to adjust to working on the night shift, which is the least effective strategy for adapting their internal, circadian clocks to a night-time schedule. That is one of the results of the first study to examine the strategies that night nurses use to adjust between day and night sleep cycles. The study was based on questionnaires from 388 nurses who work at the Vanderbilt University Medical Center and the...

Are your 11- and 12-year-olds staying up later, then dozing off at school the next day? Parents and educators who notice poor sleeping patterns in their children should take note of new research from Tel Aviv University "• and prepare themselves for bigger changes to come. Prof. Avi Sadeh of TAU's Department of Psychology suggests that changes in children's sleep patterns are evident just before the onset of physical changes associated with puberty. He counsels parents and educators to...
