Those who sleep a lot have a higher risk of a stroke
The nap is rigorous, but Chinese scientists warn that those who take them long or sleep more than nine hours at night have a higher risk of suffering a stroke, according to an article.
People who normally take a nap of more than 90 minutes during the day are 25 more likely to suffer a stroke than those who enjoy a nap of no more than half an hour.
The researchers also established that people who do not take a nap or take them between 31 minutes and one hour do not have a greater propensity to have a stroke than those who enjoy it for less than 30 minutes.
“More research is needed to understand how long naps and sleeping more hours at night may be associated with a higher risk of stroke, although previous studies have shown that those who take long naps or long at night have unfavorable changes in their levels of cholesterol and an increase in waist circumference, both risk factors for a stroke, ”said study author Xiaoming Zhang of the Huazhong University of Science and Technology in Wuhan in China.
Long naps and sleeping a lot at night can indicate an inactive lifestyle, which is also related to an increased risk of stroke.
The study involved 31,750 people in China with an average age of 62 years, without a medical history of stroke or serious illness at the beginning of the investigation, although during the six-year follow-up there were 1,557 cases of strokes
The researchers asked the participants in the experiment about their rest habits: In China, as in many other countries, noon naps are very common and 8 of the study participants said they did more than ninety minutes.
In addition, the 24 said he slept nine or more hours at night.
The researchers observed that people who sleep nine or more night hours have a 23-greater risk of having a stroke than those who do it for seven to less than eight hours.
Those who take long naps and sleep many hours at night were at 85 times greater risk of having a stroke than those who are moderate in sleep.
The scientists also asked if they slept well and found that the 29 who recognized that he was doing poorly was more likely to have a stroke than the rest.
"These results emphasize the importance of napping and moderate nighttime sleep, and maintaining good sleep quality, especially among middle-aged adults and the elderly," said Xiaoming.
