Insomnia is one of the highly recognised sleep disorders that continuously affect the sleep patterns of millions of individuals globally. In simple words, it is highly difficult for the people, suffering from insomnia to fall asleep or stay slumbering. Insomnia usually leads to daytime drowsiness, exhaustion, and a familiar feeling of being ailing both psychologically and physically. But now an international team of researchers have found out another high-risk factor of insomnia – its link-up to cardiac issues like heart attack and strokes.

According to the study paper, published today in the European Journal of Preventive Cardiology this week, “Insomnia is dangerously linked to the increased risk of heart attack and stroke.”

Earlier, a number of researchers have revealed the dangerous relationship between insomnia and poor health. But the connection between insomnia and cardiac issues has thus far been conflicting. And for confirming this link in an official manner, researchers, led by Qiao He from China looked into the relationship between the symptoms of insomnia including intricacy initiating sleep, complexity falling asleep, early morning wake up and non-restorative sleep and occurrence or deaths, caused by cardiovascular disease like coronary heart disease, acute myocardial infarction, heart failure, stroke and the combination of all such events.

The new large-scale research, conducted by a team of experts from China Medical University in Shenyang, China has revealed that people suffering from insomnia can be at higher risks of heart attack and stroke. For the study, researchers thoroughly analysed a total of 15 potential cohort research papers, containing at least a two-year notes and with a total of 160,867 sections. The aftermaths of the study revealed that people with the symptoms of insomnia like problems in initiating sleep are linked up with 27% risks of heart diseases and strokes, while individuals with symptoms like intricacy staying asleep and non-restorative sleep are connected with11%, and 18% increased threats of heart illness and stroke, correspondingly in contrast to those with no insomnia symptoms.

However, the study found no connection between early-morning wake-up and the higher risk of the heart diseases and strokes. Moreover, the study also discovered women to be more susceptible to insomnia owing to the genetic, differences as well as dissimilarities in stress and sex hormones, and reaction to stress. The research paper is published in the European Journal of Preventive Cardiology over this weekend.
