A recent discovery pointed out oversleeping increases the risk of strokes. Scientists proved people who sleep more than eight hours per night have high changes of suffering a stroke. It was estimated those who sleep longer than recommended increase their risk of having a stroke by 146 percent.
Strokes are known to occur either as a result of brain bleeding or when clots cut off blood flow to the brain. Strokes result in serious brain injuries which are the cause of adults’ disability. It was estimated that strokes, besides heart failure and cancer, are also causing many deaths among people. In England, 110, 000 citizens were reported to have experienced a stroke each year.
Also, health issues, such as high amounts of cholesterol, heart problems and diabetes can increase the chances of a stroke. A group of scientists from the New York University School of Medicine conducted a study which showed oversleeping is not healthy for one’s life. For the study, experts involved 288, 888 individuals in a survey which lasted from 2004 to 2013.
The research took into consideration factors such as health, lifestyle and demographic features. 77 percent of participants were white citizens. Half of them were aged 45 or older. Experts examined people’s sleep durations as well as physical activity, such as walking, swimming or gardening. This way they wanted to point out which factors could determine a stroke.
The results showed those who slept seven to eight hours per night had 25 percent less chances to suffer a stroke. Long sleepers, with over eight hours per night, showed 146 percent risk of experiencing a stroke. In addition, individuals who slept less than seven hours per night had 22 percent chances to suffer a stroke. Moreover, it was estimated that seven to eight hour sleep combined with daily exercising substantially decreases stroke risks.
According to scientists, there is significant evidence which points out that seven or eight hours of sleep is healthiest for most people. Researchers also discovered that people who have six to eight hours’ sleep per night are likely to live longer and have better health. On the other side, individuals who sleep less than six hours are prone to premature death.
Nonetheless, experts are not sure yet why oversleeping increases the risk of strokes. Their theory is that oversleeping can reduce the quality of sleep, making individuals feel more tired than before going to bed. Sleep disorders affect one’s memory, shrinks the brain and increase stress risk.
