Greek and Spanish scientists have found that 6-8 hours of sleep per night reduces the risk of developing cardiovascular disease and prolongs life. At the same time, if a person sleeps less than six hours a day or often wakes up at night, then he has an increased likelihood of asymptomatic atherosclerosis.. About this, writes Lenta. ru, according to press releases on EurekAlert!

In the first work, experts analyzed data obtained over the past five years in the course of 11 prospective studies, when several groups of people are observed for a long time, differing in certain characteristics.. In total, more than one million healthy adult patients (1,000,541 people) have been examined.. They were divided into three conditional groups, in one of which people slept less than six hours a day, in the second - more than eight hours, and the third was a control group (six to eight hours of sleep per day).

It turned out that during the 9.3 years of follow-up, compared with the control group, the risk of coronary heart disease and stroke increased by 11 and 33 percent, respectively, in the remaining patients..

Another study involved 3,974 volunteers who wore sleep-tracking devices for seven days.. The average age of the subjects was 46 years. It turned out that those who slept less than six hours a night or had fragmented sleep, increased the risk of atherosclerosis, obesity and diabetes..
