Most people have experienced insomnia at some stage in their lives. If, however, it becomes chronic, it might be a good idea to get professional help. Bad news for people who toss and turn all night is that insomnia appears to be linked to a heightened risk for heart attack or stroke, a Chinese research review suggests.
"We found that difficulty initiating sleep, difficulty maintaining sleep, or non-restorative sleep were associated with 27%, 11%, and 18% higher risks of cardiovascular and stroke events, respectively," said study co-author Qiao He.
The findings were published in the European Journal of Preventive Cardiology. The reasons why aren't fully understood, said He, a graduate student at China Medical University in Shenyang. However, the study doesn't establish a cause-and-effect relationship.
