Recommend to others!

Many people especially those who are adults experienced sleeping disorders such as sleepless nights for unknown reasons. This is medically known as insomnia. It is estimated that the major population is affected by this disorder, reaching about 30 to 50 per cent of the general population. Having this disorder is already troublesome. The discomfort it brings during night time to individuals affected with it is stressful because they are already supposed to be having a deep sleep to regain the energy needed for another day’s work. Moreover, insomnia can also increase the risk of an individual to have a heart attack, a new study suggests.

Insomnia is a more of symptom rather than a disease. When people experienced this phenomenon, they are more likely as well to experience weight gain, changes in lifestyle, stress at work and at home, and other environmental issues. Insomnia has significant impact on a person’s life. It can create alteration on the quality of life that may lead to the development of other diseases. In fact, according to the new study, people who experienced difficulty of sleeping at night can have a moderately increase risk of having heart attack.

The new study was reported in Circulation: Journal of the American Heart Association.
The study involves the examination and analysis of data gathered from about 52,610 Norwegian adults. The data collected were part of a national health survey dated back in the year 1995 to 1997. Furthermore, the researchers inspect various hospital records and death registry in order for them to identify individuals who had incidences of first time heart attacks during the eleven (11) years follow up of the study. Then, the researchers identified about 2,368 cases of first time heart attacks.

Other factors that might affect the study such as age, sex, marital status, educational attainment, cholesterol, blood pressure, weight, lifestyle, and shift work were adjusted by the researchers by using a survival analysis. Also, other contributory factors which may cause the occurrence of insomnia were taken into account by the researchers.

Moreover, the conclusions of the study reveal that about 33 per cent of the total population experienced insomnia. In addition, the researchers also concluded that the risk of heart attack for those individuals who experienced having difficulty or trouble in sleeping have about 27 per cent to 45 per cent heightened risk which is considered a moderate increase to the risk, as compared to those who do not or rarely experience sleeping disorders.

    It seems like people don’t take sleep seriously, or else they just don’t understand the significant side effects of not getting enough sleep. Thanks for the article and the interesting statistics!
