A survey of police officers indicated that about 40 percent have a sleep disorder, which was associated with an increased risk of adverse health, safety and performance outcomes, according to a study in the December 21 issue of JAMA. Sleep disorders, such as obstructive sleep apnea, insomnia, and shift work disorder, affect 50 to 70 million U.S. residents. Most are undiagnosed and remain untreated. The study was conducted by Shantha M. W. Rajaratnam, Ph.D., of Brigham and Women’s Hospital, Boston, and colleagues. Included in this report is a video summary of the study results.
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 to 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.
Researchers from Norway have uncovered an association between sleep problems and increased risk of fibromyalgia in women. The risk of fibromyalgia increased with severity of sleep problems, and the association was stronger among middle-aged and older women than among younger women. Results of the prospective study, based on ten years of data, appear in Arthritis & Rheumatism, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology (ACR).
Drinking cherry juice significantly improves both the quality and duration of sleep, according to new findings from Northumbria University. Researchers from the School of Life Sciences have found that Montmorency cherry juice significantly increases the levels of melatonin in the body, the hormone which regulates sleep, and could benefit those who have difficulty sleeping due to insomnia, shift work or jet lag.
Insomnia is costing the average U.S. worker 11.3 days, or $2,280 in lost productivity every year, according to a study in the September 1 issue of the journal Sleep. As a nation, the total cost is 252.7 days and $63.2 billion.
Treating sleep problems with cognitive-behavioral therapy (CBT) for insomnia can reduce suicidal ideation, suggests a research abstract that will be presented Tuesday, June 14, in Minneapolis, Minn., at SLEEP 2011, the 25th Anniversary Meeting of the Associated Professional Sleep Societies LLC (APSS).
In the largest study of it kind to establish a link between sleep and diabetes, researchers found that people with diabetes who sleep poorly have higher insulin resistance, and a harder time controlling the disease.

A brief behavioral treatment consisting of two in-person sessions and two phone calls appears to alleviate insomnia in older adults for at least six months, according to a report posted online today that will be published in the May 23 print issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
Depression appears to be associated with a molecular-level disturbance in the body’s 24-hour clock, new research suggests. Scientists examined genes that regulate circadian rhythm in people with and without a history of depression. As a group, those with a history of depression had a higher level of activity of the so-called Clock gene, which has a role in regulating circadian rhythm, than did people with no mood disorders. The research is published in a recent issue of the Journal of Affective Disorders.
