Well, we all know that not enough sleep is not beneficial for our health, but a recent study also showed that too much rest is also bad for people. More specifically, sleeping more than 8 hours per night increases risks of premature death, reported Advocator, citing the new research carried out by the Keele University.
The researchers reviewed the data from more than 70 previous studies, gathered between 1970 and 2017, which explored the sleeping habits of more than 3 million people.
Besides, the scientists from the Universities of East England, Manchester, and Leeds found that those who sleep more than 8 hours per night present a heart disease risk by 44% higher.
On the other hand, the Keele University’s scientists observed that people who enjoy resting for more than 10 hours present a raised risk for stroke, by 56%, and for cardiovascular diseases, by 49%.
The sleeping pattern, the new study says, is an essential criterium for health evaluation as it is a “marker of elevated cardiovascular risk,” according to the researchers.
Sleeping more than 8 hours per night increases risks of premature death
“Our study has an important public health impact in that it shows that excessive sleep is a marker of elevated cardiovascular risk. If excessive sleep patterns are found, particularly prolonged durations of eight hours or more, then clinicians should consider screening for adverse cardiovascular risk factors and obstructive sleep apnea,” explained Dr. Chun Shing Kwok, the new study’s leading author.
Dr. Kwok also explained that apnea is “a serious sleep disorder that occurs when a person’s breathing is interrupted during sleep,” and, even more, some specialists linked this condition with sleeping more than usual.
However, even though the results are quite surprising, the scientists who worked on this research admitted that the outcomes might be biased as the duration of sleep was self-reported and the subjects could’ve had unknown mental or physical disorders that might influence their sleeping patterns.
The researchers are now looking for further investigation in this direction to see if sleeping more than 8 hours per night is indeed boosting the risks of premature death.
