sleep loss
Most Americans welcome the switch to daylight saving time each March, mostly because of the longer days, but they also dread losing an hour of sleep after they move their clocks ahead one hour. A new study shows that losing just an hour of sleep could pose some dangerous consequences for those in hazardous work environments.
The study’s findings are published in the September, 2009 issue of the Journal of Applied Psychology, which is published by the American Psychological Association.

One-third of Americans are losing sleep over the the U.S. economy and other personal financial concerns, according to a poll released by the National Sleep Foundation (NSF). The poll suggests that inadequate sleep leads to unhealthy lifestyles and negatively impacts health and safety.
NSF’s Sleep in America poll reveals striking disparities in the sleep patterns, health habits and quality of life between healthy and unhealthy Americans. Those in good health are two-times more likely than those in poor health to work efficiently, exercise, or eat healthy because they are getting enough sleep.

Children and teens who get less sleep, especially those who spend less time in rapid eye movement (REM) sleep, may be more likely to be overweight, according to a report in the Archives of General Psychiatry.
The obesity rate has more than tripled among children six-to-11 years in the past 30 years, and approximately 17 percent of U.S. adolescents are now overweight or obese, according to background information in the article.

Post-partum depression (PPD) may lead to poor sleep quality, a study of 46 post-partum women shows.
Sleep deprivation may hamper a mother’s ability to care for her infant because judgment and concentration decline. Sleep-deprived mothers may also inadvertently compromise their infants’ sleep quality as infants often adopt their mothers’ circadian rhythms.

The number of patients assigned to medical residents and the complexity of care patients require has just as much impact on residents’ training as the number of hours they work, according to a study published by researchers at the University of Chicago Medical Center in the September 10, 2008 issue of JAMA.
The study is believed to be the first of its kind using information gathered objectively from medical residents who work long shifts as part of their training.

Loss of sleep, even for a few short hours during the night, can prompt one’s immune system to turn against healthy tissue and organs.
A new article in the September 15, 2008 issue of Biological Psychiatry, by the UCLA Cousins Center research team, reports that losing sleep for even part of one night can trigger the key cellular pathway that produces tissue-damaging inflammation. The findings suggest a good night’s sleep can ease the risk of both heart disease and autoimmune disorders such as rheumatoid arthritis.

Just one night without sleep can increase the amount of the chemical dopamine in the human brain, according to new imaging research in the August 20 issue of the Journal of Neuroscience. Because drugs that increase dopamine, like amphetamines, promote wakefulness, the findings offer a potential mechanism explaining how the brain helps people stay awake despite the urge to sleep.
However, the study also shows that the increase in dopamine cannot compensate for the cognitive deficits caused by sleep deprivation.

~~ Apnea in United States ~~
As of May 2, 2009 at 9:47 p.m. (-0500) (ET), the U.S. population
was 306,340,710. Sleep researchers estimate approximately seven percent
of the population suffers from obstructive sleep apnea. Using that
estimate, there are potentially 21,443,850 apneics in the U.S.
~~ Apnea around the world ~~
As of May 2, 2009 at 9:47 p.m. (-0500) (ET), the world population
