Despite recently mandated reductions in medical student workload hours, a new study reveals the widespread presence of job stress, and sleep deprivation among physicians and nurses in teaching hospitals. When asked to keep a running account of work activity, patient load, and work stress using handheld computers, physicians reported much higher levels of work stress than nurses.
Sleep deprivation adversely affects automatic, accurate responses and can lead to potentially devastating errors, a finding of particular concern among firefighters, police officers, soldiers and others who work in a sleep-deprived state, University of Texas at Austin researchers say.
Bruxism, the medical term for the grinding of teeth during sleep, is prevalent in Caucasians with sleep disorders, a study has found. There is a high prevalence of nocturnal teeth grinding, or bruxism, in patients with obstructive sleep apnea, particularly in Caucasians.
Don Spence, chief executive officer of Philips Home Healthcare Solutions, has issued a written statement endorsing the Centers for Disease Control and Prevention (CDC) educational initiative to increase awareness about sleep deprivation.
A research collaboration led by biologists and neuroscientists at the University of Pennsylvania has found a molecular pathway in the brain that is the cause of cognitive impairment due to sleep deprivation.
According to research findings presented Wednesday, June 10, at Sleep 2009, the 23rd annual meeting of the Associated Professional Sleep Societies, caffeine use prevents increased risk-taking that occurs after several nights of total sleep deprivation.
Results indicate that despite extreme sleep deprivation, participants who had consumed caffeine did not exhibit increased risky behavior on the Balloon Analog Risk Task (BART), a computerized measure of impulsive risk-taking, according to the findings, released in abstract form, titled, “Caffeine Protects Against Increased Risk-Taking Behavior During.”
Individuals who get less than seven hours of sleep per night appear about three times as likely to develop respiratory illness following exposure to a cold virus as those who sleep eight hours or more, according to recent research findings.
Studies have demonstrated that sleep deprivation impairs some immune function, according to background information in the article. Research indicates that those who sleep approximately seven to eight hours per night have the lowest rates of heart disease illness and death. However, there has previously been little direct evidence that poor sleep increases susceptibility to the common cold.
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.

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.
