Sleeping more than eight hours a day increases the risk of cardiovascular disease



Sleeping more than eight hours a day increases the risk of cardiovascular disease

Sleeping is one of the most enjoyable and necessary activities that a human being does daily. Along with food and water intake, rest is essential to maintain good health both physically and mentally.

There are, however, people who prolong their recommended sleep for more than an hour, believing that when they sleep more, they will be healthier, but this way of thinking is not quite true.

According to a study published in the European Heart Journal, the number of hours a person sleeps, including support, is related to the risk of developing cardiovascular disease.

They found that people who sleep more than eight hours a day are more likely to die, suffer from heart disease or blood vessels in the brain than those who sleep at the recommended time.

The study lasted almost eight years and estimated 116,632 people aged between 35 and 70 in 21 countries. During this period 4381 died and 4365 suffered from cardiovascular disease.

The study revealed that those who slept between eight and nine hours had a 5% risk and those who had between nine and ten hours had a risk of 17% and those who slept for more than ten hours per day, had 41%,

However, everything has to be balanced because those who rest less than six hours represent a risk of 9%.

For every one thousand people who sleep less than six hours, 9.4 developed cardiovascular disease or died each year; among those who slept six to eight hours this happened in 7.8.

In the group that was resting from eight to nine o'clock, she moved to 8.4; those who slept nine to ten o'clock 10.4 and those who slept after 10 o'clock, 14.8.

Leading author Chuangshi Wang, PhD student at McMaster and Peking Union Medical College, said: "Our study shows that the optimum duration of sleep is 6-8 hours per day for adults."

Salim Yusuf, a professor of medicine and executive director of the Institute for Population Health Studies at McMaster University and Hamilton, added: "The public must ensure that they sleep between six and eight hours a day, if you sleep too regularly, more than nine hours a day, you may want to visit a doctor to monitor your overall health.
