Lack of sleep can put your heart at risk, says new research


The study has been published in the Journal of the American College of Cardiology.

If you are a proud insomniac, don’t be happy. Be scared. Yes, if you are among those men who don’t sleep much, your heart may be at risk.

A new study has shown that men who sleep less than six hours a night may face an increased risk of heart diseases in comparison to men who enjoy a seven to eight hours sleep.

According to the study, not having enough sleep can increase the risk of atherosclerosis by 27 per cent compared to seven to eight hours of sleep.

The build-up of fats, cholesterol and other substances in and on the artery walls throughout the body is known as Artherosclerosis.

The research suggests that women who sleep more than eight hours a night were at a greater risk of Artherosclerosis.

“Cardiovascular disease is a major global problem and we are preventing and treating it using several approaches, including pharmaceuticals, physical activity and diet,” Jose M. Ordovas, researcher at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) in Madrid, was quoted as saying by news agency IANS.

“But the study emphasizes we have to include sleep as one of the weapons we use to fight heart disease — a factor we are compromising every day,” Ordovas added.

To conduct the study, a team of 3974 bank employees were surveyed among which all were without known heart disease and two-thirds were men.

The study has been published in the Journal of the American College of Cardiology.

The study also shows that consumption of caffeine and alcohol can cause short and disrupted sleep.

“Many people think alcohol is a good inducer of sleep, but there’s a rebound effect. If you drink alcohol, you may wake up after a short period of sleep and have a hard time getting back to sleep. And if you do get back to sleep, it’s often a poor-quality sleep,” Ordovas said.

That a lack of sleep can result in cardiovascular diseases has always been a known fact. Lack of sleep can put the heart at risk by increasing heart disease risk factors such as glucose levels, blood pressure, inflammation and obesity.
