Sleeping lessons illuminate the alarm for pillow lovers | Spanish.xinhuanet.com



BEIJING, 13 dec. (Xinhua) – To leave the heat in bed in winter is difficult for many people. But a new study that connects excess sleep hours with health risks may sound the alarm for those who sleep late.

The study, published in the European Heart Journal, shows that people who sleep more than eight hours a day may also have an increased risk of heart disease and blood disorders and even death.

Researchers from Beijing Fuwai Hospital in China and from McMaster University in Canada worked on the study involving 116,632 people aged 35-70 in 21 countries since 2003. After nearly eight years, researchers recorded 4,381 deaths and 4,365 cases. of cardiovascular disease.

Experts took into account factors that could affect results such as age, sex, smoking, alcohol consumption, family history of cardiovascular disease, diabetes and blood pressure.

They found that people who slept six to eight hours a day had the lowest fatalities and diseases. Sleep less or more than what was associated with an increased risk, but the surplus showed greater danger than lack of sleep.

Sleeping eight to nine hours a day increased the risk by five percent; from nine to 10 hours, 17 percent and more than 10 hours, 41 percent. Less than six hours increased the risk by nine percent.

The researchers also found that nap during the day (about 30 to 60 minutes) could increase the risk, except in people sleeping less than six hours at night.

This research has limitations, including the assumption that sleep duration did not change during the follow-up period, and no information on sleep disturbances such as insomnia and apnea was collected, which also had an effect on sleep and could affect sleep. health

But the result looks like a survey conducted by British researchers last month, which showed that women who slept more than eight hours a night had a 20 percent higher risk of breast cancer for each additional sleep.

The duration of sleep can help doctors identify people at high risk of cardiovascular disease or death problems, said Wang Chuangshi, lead author of the study.
