Harvard study: Less 5 hours sleeping a day more than doubling the risk of dementia and all-cause mortality.

In modern society, daily work, study and life put us under great pressure. One of the most significant problems that these pressures bring us is lack of sleep .

According to the statistics of the World Health Organization (WHO) , the global sleep disorder rate reaches 27% , and In China, the incidence of insomnia among adults is as high as 38.2% , and more than 60% of the post-90s generation feel sleep deprivation.

That is to say, more than 300 million Chinese have sleep disorders, and this data is still increasing year by year.

 

Sleep disturbances and insufficiencies are more common in older adults, and studies have linked them to dementia and risk of all-cause mortality.

 

In February 2021, researchers from the Department of Sleep Medicine at Harvard Medical School and Brigham and Women’s Hospital affiliated with Harvard Medical School published a study in the journal Aging entitled: Examining sleep deficiency and disturbance and their risk for incident dementia and all -Research paper on cause mortality in older adults across 5 years in the United States .

 

This prospective study showed that sleep disturbance and sleep deprivation were associated with an increased risk of dementia and all-cause mortality , with those who slept less than 5 hours a day more than doubling the risk of dementia and all-cause mortality .

 

The findings shed light on the link between sleep deprivation, poor sleep quality and the risk of dementia and death, adding new evidence for the importance of sleep for brain health and suggesting that improving sleep and treating sleep disorders may be a treatment for Alzheimer’s disease. Zheimer’s disease and potential means of reducing the risk of death .

To study the link between sleep quality and sleep duration and the risk of dementia and death, the research team used data from the National Health and Aging Trends Study (NHATS) , a study of Medicare benefits 65 and older.

Longitudinal study of people, survey data from participants has been collected annually since 2011, so the data are very representative. A total of 2,610 participants were surveyed on sleep problems in 2013 and 2014.

 

The researchers surveyed participants on several characteristic questions about sleep disturbances and lack of sleep, including alertness, napping frequency, time it took to fall asleep, sleep quality (good, moderate, poor) , sleep duration, and snoring.

 

The research team then also collected these participants’ follow-up health conditions from the survey, primarily dementia and death from any cause . The overall investigation time is 5 years.

 

Overall, the research team found a strong link between sleep disturbances and sleep deprivation and dementia over time, with those who typically took 30 minutes or more to fall asleep had a 45-fold increased risk of dementia. %, those who slept less than 5 hours a day had a doubled risk of dementia.

In addition, the study also found that low alertness after waking up , frequent naps , poor sleep quality , and less than 5 hours of sleep per night were all associated with all-cause mortality, with less than 5 hours of sleep per night being the most significant, and less than 5 hours of sleep per night. associated with a 138% increased risk of death.

This prospective study shows that for these older adults, sleep deprivation more than doubles the risk of dementia and all-cause mortality over the next 4 to 5 years.

 

The findings shed light on the link between sleep deprivation, poor sleep quality and the risk of dementia and death, adding new evidence for the importance of sleep for brain health and suggesting that improving sleep and treating sleep disorders may be a treatment for Alzheimer’s disease.
