The following is the The study found a high risk of dementia due to chronic sleep deprivation From Nature communication recommended by recordtrend.com. And this article belongs to the classification: Life data.

Sleep takes up almost a third of your life. It is conceivable that adequate sleep must be of great significance to physiology. However, with the increasing pressure of life, to ensure seven hours of “regular” sleep every night has become an extravagant demand for many people. Occasionally one or two days of lack of sleep, some people may feel slow thinking, attention is not easy to focus.

Long term lack of sleep, the consequences are more serious, more and more scientific research shows that physical and mental health will be harmed.

A new study published today in nature letters adds another piece of evidence for the long-term effects of sleep deprivation: after 25 years of follow-up of nearly 8000 British adults, researchers found that those who regularly sleep less than six hours in middle age, in later life, tend to sleep less than six hours, There is a higher risk of Alzheimer’s disease and other dementia (also known as dementia).

In the past, the evidence for the correlation between sleep time and dementia mostly came from short-term (less than 10 years) follow-up studies, the researchers said in the paper. However, since most pathophysiological changes of dementia can span 20 years or even longer, it is necessary to understand the relationship between sleep duration and the incidence rate of dementia by long-term follow-up study, and begin tracking investigation from the participants before entering the age of 65.

The newly published study includes the health status of nearly 8000 British adults since 1985. Sleep time was measured at the age of 50, 60 and 70. In addition to participants’ self-report of how long they slept, a considerable number of them would also wear special equipment for the night to confirm whether the estimation of duration was accurate.

During a mean follow-up period of 25 years, 521 cases of dementia were diagnosed. Analyzing participants’ sleep time, it was found that those who slept less at the age of 50 or 60 were more likely to develop dementia. Overall, people who sleep less than six hours a night from middle age to old age (50-70 years) have a 30% increased risk of dementia compared with those who sleep seven hours a night for a long time.

The study also analyzed some possible influencing factors and found that the association between sleep time and the risk of dementia had nothing to do with mental illness and cardiovascular metabolism. That is to say, although depression and other mental problems and cardiovascular health are known factors affecting dementia, they can not be used to explain the relationship between less sleep and high risk of dementia.

In the conclusion, the paper emphasizes that the short sleep time in middle age is associated with the increased risk of late-onset dementia. Although this study has not established a causal relationship as a correlation study, these data suggest that sleep may be important for middle-aged brain health.

Researchers point out that more and more evidence suggests that sleep patterns before the onset of dementia may affect the occurrence and development of the disease. Future research may further determine whether improving sleep habits can help prevent dementia. But even if we don’t have a clear result yet, it’s always right to guarantee sleep time.
