A new study is about correlating sleep times with the possibility of premature death. In particular, people who sleep more than eight hours each night face a higher cardiovascular risk and are more likely to die prematurely than those who sleep for seven hours, according to a new major British study.
Those who usually sleep around ten hours a day (which is, of course, uncommon in our time) have a 30% greater risk of premature death than those who sleep for seven hours (considered “normal”). Ten-hour sleep is also associated with a 56% increased risk of fatal stroke and 49% fatal heart attack.
Researchers at the University of Manchester, Kilk, Linz and East of England, who published the publication in the American Journal of American Heart Association, evaluated (meta-analysis) the findings of 74 studies on both duration and sleep quality and the impact on health.
Researchers have pointed out that excessive sleep should be considered as evidence of a potential cardiovascular risk. The study also concluded that inadequate and poor quality sleep is associated with a 44% increase in risk for coronary artery disease.
