According to new research by Keele University, a 10-hour sleep per night increases – compared to a 7-hour sleep – by 30% the risk of death, 56% the risk of stroke and 49% the risk of cardiovascular mortality
Researchers at Keele University analyzed 74 medical cases related to mortality, cardiovascular effects, sleep duration and quality of sleep, supported by colleagues at the University of Manchester, University of Leeds and University of East Anglia (Norwich, England). The results of their research were published in The Journal of the American Heart Association.
Overall, the behavior and health of more than three million participants were examined to determine whether it was more dangerous to sleep below or above the recommended sleep duration of seven at eight o'clock
Thus, scientists found that a 10-hour sleep increased the risk of coronary heart disease by 44%.
"Our study is important for public health because it shows that excessive sleep is a marker of high cardiovascular risk," said Dr. Chun Shing Kwok.
And to conclude: "Our results have important implications and clinicians should take more into account the duration and quality of sleep during consultations. If they experience excessive sleep, especially eight hours or more, clinicians should consider screening for cardiovascular risk factors and obstructive sleep apnea, a serious sleep disorder. "
