Sleep more than eight hours a day increases the risk of cardiovascular disease
Sleep is one of the most enjoyable and most important activities that a person performs daily. Together with the intake of food and water, rest is essential to maintaining good health both physically and mentally.
However, there are those who prolong their recommended sleep for several hours because they believe that if they sleep more, they will be healthier, but this way of thinking is not entirely true.
According to a study published in the European Heart Journal, the number of people sleeping, including sleeping, is associated with a risk of developing cardiovascular disease.
They found that people who sleep more than eight hours a day are more likely to die, will have heart disease or blood vessels in the brain compared to those who sleep at the recommended time.
The study lasted for nearly 8 years and evaluated 116,632 people aged 35 to 70 in 21 countries. During this period, 4381 and 4365 died of cardiovascular disease.
Research revealed that those who slept between eight and nine hours had a 5% risk, those who were nine to ten hours had a 17% risk, and those who slept more than ten hours had a 41%
Nevertheless, everything has to be balanced because those who rested less than six hours represented a 9% risk.
For every one thousand people who slept less than six hours, 9.4 caused cardiovascular disease or died each year; among those who slept six to eight hours, it happened at 7.8.
In the group that was resting from 8 am to 9 pm she went through 8.4; those who slept nine to ten o'clock 10.4 and those who slept in ten o'clock, 14.8.
Leading author Chuangshi Wang, a PhD study program at McMaster and Peking Union Medical College, said: "Our study shows that the optimal duration of anticipated sleep is for adults six to eight hours a day."
Salim Yusuf, professor of medicine and executive director of the McMaster University Research Institute for Human Health at Hamilton Health Sciences, said: "The general public should ensure that they sleep between six and eight hours a day, and if you sleep too often, more than nine hours a day, you may want to visit a doctor who will monitor your overall health.
