"Oct. 24, 2011 -- Poor sleepers who toss and turn most nights may be at risk for more than just daytime sleepiness.
Chronic insomnia has been linked to depression and anxiety, and now a large study from Norway finds that it may also increase the risk of heart attacks.
People in the study with insomnia symptoms had more heart attacks than people without insomnia symptoms, and those with the most symptoms had the highest risk.
Study researcher Lars Erik Laugsand, MD, of the Norwegian University of Science and Technology, says more research is needed to confirm the findings in different populations and to understand how lack of sleep may affect the heart."
