Sleep restriction reduces heart rate variability
WESTCHESTER, Ill. – Chronic sleep restriction has a negative effect on a person's cardiac activity, which may elevate the risk of cardiovascular disease and mortality, according to a research abstract that will be presented Wednesday at SLEEP 2007, the 21st Annual Meeting of the Associated Professional Sleep Societies (APSS).
The study, conducted by Siobhan Banks of the University of Pennsylvania School of Medicine, was based on preliminary analyses of 39 subjects, each of whom participated in a laboratory-controlled chronic sleep restriction protocol. The subjects underwent two nights of baseline sleep followed by five hours of sleep restriction. The results showed a statistically significant decrease in the heart rate variability after five nights of sleep restriction.
"A reduction in the heart rate variability has been reported in several cardiological and non-cardiological diseases," said Banks. "If our finding is sustained by a larger group and further analysis, it may suggest why short sleep duration is associated with a heightened risk of cardiovascular disease and mortality."
The amount of sleep a person gets affects his or her physical health, emotional well-being, mental abilities, productivity and performance. Recent studies associate lack of sleep with serious health problems such as an increased risk of depression, obesity, cardiovascular disease and diabetes.

Experts recommend that adults get between seven and eight hours of sleep each night to maintain good health and optimum performance.
Those who think they might have a sleep disorder are urged to discuss their problem with their primary care physician, who will issue a referral to a sleep specialist.
The annual SLEEP meeting brings together an international body of 5,000 leading researchers and clinicians in the field of sleep medicine to present and discuss new findings and medical developments related to sleep and sleep disorders.
More than 1,000 research abstracts will be presented at the SLEEP meeting, a joint venture of the American Academy of Sleep Medicine and the Sleep Research Society. The four-day scientific meeting will bring to light new findings that enhance the understanding of the processes of sleep and aid the diagnosis and treatment of sleep disorders such as insomnia, narcolepsy and sleep apnea.

美国伊里诺州WESTCHESTER市.慢性睡眠限制为人类心脏活动一个消极影响因素，可能增加心血管疾病的危险性和死亡率，根据某一科研摘要，睡眠专业联合组织（APSS）的21届年会将在2007年汇报况。
The study, conducted by Siobhan Banks of the University of Pennsylvania School of Medicine, was based on preliminary analyses of 39 subjects, each of whom participated in a laboratory-controlled chronic sleep restriction protocol. The subjects underwent two nights of baseline sleep followed by five hours of sleep restriction. The results showed a statistically significant decrease in the heart rate variability after five nights of sleep restriction.
宾夕凡尼亚州立大学医学院siobhan学术团队的研究中， 39个受试者参与实验，他们分别参与控制性的慢性休眠的实验过程。其中，受试者接受两夜睡眠基线，随后，行五个小时睡眠限制，实验结果示：五个晚上睡眠限制后，心率变异性显著降低，有统计学意义。
A reduction in the heart rate variability has been reported in several cardiological and non-cardiological diseases," said Banks. "If our finding is sustained by a larger group and further analysis, it may suggest why short sleep duration is associated with a heightened risk of cardiovascular disease and mortality."
据siobhan学术团队的调研中，在数种心脏和非心脏疾病中，已有心率变异性降低的相关报道。
在调研中提到：如果在接下来的提高样本例数及进一步研究后，其研究结论可能提示，为何
较高危心血管疾病发生率和死亡率与短期睡眠相关。
