Lack of Sleep Increases the Chance of Death from Heart Failure

Sleep plays a very important role in our physical health as it involves in the process of healing and repair of our heart and blood vessels. Thus, constant sleep deficiency can be linked to an increased risk of heart ailments and other organ failures.

In a recent study conducted by the U.S. researchers and was published in the Journal of the American Heart Association, the researchers claimed that not getting enough sleep can increase and even double the chances of dying from heart failure or stroke, particularly among the people with risk factors such as diabetes, obesity high blood pressure and high cholesterol.

The said findings were based on some 1,344 adult participants with an average age of 49-year old, and 42 percent of which were men. All of them were randomly selected for a sleep research in Pennsylvania.

The participants were asked to undergo a series of health screenings and spend a night in a sleep laboratory.

Subsequently, the study found out that over 39 percent of them have three risk factors for heart ailments which, when gathered together, are most known as metabolic syndrome.

Said factors include a body mass index (BMI) higher than 30, high cholesterol, high blood pressure, high fasting blood sugar and high triglyceride levels.

Participants were observed for an average of 16 years and some 22 percent of them succumbed to death during the period.

The researchers claimed that those with metabolic syndrome who slept less than six hours were 2.1 times more likely to die from heart disease or stroke than those who do not possess at least three risk factors for heart ailments.

“The short sleepers with metabolic syndrome were also 1.99 times more likely to die from any cause compared to those without metabolic syndrome,”


Participants with high risk who slept more than six hours faced a 1.49 times increased risk of dying than those without the risk factors.

Therefore, researchers suggest the adults should get at least seven to eight hours of sleep at night.

“If you have several heart disease risk factors, taking care of your sleep and consulting with a clinician if you have insufficient sleep is important if you want to lower your risk of death from heart disease or stroke,”

The research was described as the first study to measure sleep duration in an actual sleep laboratory setting, rather than relying on participants’ reports. Also, it was said to be the first time to examine the effect of sleep duration on the risk of death in those people with multiple heart ailment risk factors.

However, because the study was observational in nature, it ceased short of proving any cause and effect according to reports.

“Future clinical trials are needed to determine whether lengthening sleep, in combination with lowering blood pressure and glucose, improves the prognosis of people with the metabolic syndrome,”
