Less Sleep Can Increase The Risk Of Heart Disease

The scientists at the American College of Cardiology have researched that people who sleep for less than six hours at night are prone to heart diseases.

This research was published in the Journal of the American College of Cardiology (JACC) on January 14th, 2019.

The study stated that less sleep increases the risk of heart disease. The risk factors also include an increase in glucose levels, inflammation, blood pressure, and obesity.

Under this new PESA (Progression of Early Subclinical Atherosclerosis) CNIC-Santander study, 3,974 bank employees participated. Two-third of the participants were men and all were reported to be healthy without any heart disease.

The study was led by Valentin Fuster who is the editor-in-chief, MD of JACC. The imaging techniques were used in the study to detect the occurrence of vascular disturbances in people of the age till 46 years.

A small device known as actigraph was used by the participants to measure their sleep. This device continuously analyzed the activities or movements among them for about seven days.

Four groups were formed among the participants: who slept for more than eight hours, who slept seven to eight hours, who slept six to seven hours, and who slept less than six hours.

To check for the changes in the heart, the participants went through cardiac CT scans and 3D heart ultrasound.

José M. Ordovás, the senior study author said, “Cardiovascular disease is a major global problem, and we are preventing and treating it using several approaches, including pharmaceuticals, physical activity, and diet. But this 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.”

Ordovás further explained, “This is the first study to show that objectively measured sleep is independently associated with atherosclerosis throughout the body, not just in the heart.”

This new study is not similar to the previous researches done on sleep and heart health. It is considered to be greater than earlier studies that concentrated on the health of the population.

The previous studies included people with other health problems. Whereas a few studies were based on some questionnaires to find the kind of sleep people get. However, this new study used actigraphs to get real information regarding sleep.

It was found in a new study that people who sleep for less than six hours have a greater risk of atherosclerosis than those who sleep for seven to eight hours.

Atherosclerosis is a disease that develops in the arteries due to the collection of fats in its inner walls.

At the same time, people who have a quality sleep lead a healthy life than those who frequently wake up at night during their sleep.

It was also found that women who slept more than eight hours at night have an increased risk of heart disease. The study revealed that people who consume more caffeine and alcohol gets short and disrupted sleep.

The researchers aim to create a world free of heart diseases with improved health care. For this, the researchers are looking forward to conducting further studies to look out for other causes of heart disorders.

They also suggested that quality sleep should be the preference along with a healthy diet and exercise for an improved lifestyle.
