Poor Sleep Habits Might to Heart Disease


new study proves that a person needs to sleep the right amount of time - not more and not less than seven hours, in order to maintain a healthy heart for a long period of time.

There are a lot of negative effects related to poor sleep habits. Some of them are perceived almost instantly, such as tiredness, loss of concentration and lack of energy to carry out various tasks. Others are seen after a longer period of time. These effects include obesity, cognitive impairment and heart disease.

Now a new study proves that a person needs to sleep the right amount of time – not more and not less than seven hours, in order to maintain a healthy heart for a long period of time.

A group of  Korean researchers surveyed and tested about 47,000 adult people of various ages. During the first stage of the trial, the participants were questioned about their sleep habits and then they were tested to check if there were any coronary artery lesions, by assessing the presence of calcium on the walls of the coronary arteries. Their arterial stiffness was measured as well, by measuring the speed of the pulse wave from the arteries to the upper arm and ankle.

After they looked at the data, it was revealed that the people who slept nine hours or more than that every night had more than 70 percent calcium in their arteries than those who spent the recommended seven hours per night resting. Those who slept five hours or even less than that had 50 percent more calcium than people with good sleeping habits.

“We also observed a similar pattern when we measured arterial stiffness. Adults with poor sleep quality have stiffer arteries than those who sleep seven hours a day or had good sleep quality. Overall, we saw the lowest levels of vascular disease in adults sleeping seven hours a day and reporting good sleep quality,” said study co-author Yoosoo Chang, who is an associate professor in the Center for Cohort Studies at Kangbuk Samsun Hospital.

The study is very relevant for health experts who want to evaluate the risk of suffering from heart disease that their patients might be facing, but also for people, who need to know how important it is to have a good rest every night.

In order to do that, people need to have a healthy diet and get enough exercise, avoid drinking too much coffee, especially before going to bed. They should also go to bed and wake up at about the same hour every day and dim the light in their bedroom before they go to sleep.

The results of the study were published in the journal Arteriosclerosis, Thrombosis and Vascular Biology.
