Mastering five key sleeping habits can lower your risk of dying by 30 percent, a study suggests.
Harvard University researchers claim they have carried out one of the most comprehensive pieces of sleep research to date.
They say that while previous research has looked at the duration of sleep, other bedtime behaviors had been neglected.
Using their new five-rule method, the researchers estimate 8 percent of all deaths from any cause in the US can be attributed to poor sleep patterns.
People who hit all five criteria were 30 percent less likely to die for any reason, compared to those who met none or one of the sleep habits, the Harvard researchers found
The five components are: getting seven to eight hours a night, difficulty falling asleep no more than two nights a week, trouble staying asleep no more than two times a week, not using any sleeping pills and feeling well rested after waking up at least five days a week.
Almost a third of US adults routinely fail to get the bare minimum of seven hours of sleep every night recommended by the Centers for Disease Control and Prevention (CDC).
Sleep is essential downtime for the brain and body to recuperate and repair, and those who don’t get enough or wake up repeatedly may have higher risks of a host of illnesses including coronary heart disease and cancer.
It is the first time a nationally representative sample has been used to examine how sleep habits more generally, rather than just sleep duration, might influence life expectancy, the study authors claimed.
Researchers from Harvard’s Beth Israel Deaconess Medical Center in Boston looked at data from 172,321 people between 2013 and 2018.
The data came from people who took part in the National Health Interview Survey, a yearly general health survey by the Centers for Disease Control and Prevention (CDC) and the National Center for Health Statistics which includes questions on sleep.
The research team linked the data to the National Death Index records to investigate the link between people’s sleep factors and cause of death.
The five sleep habits to slash your risk of dying by 30 percent
They examined five different indicators of sleep quality: ideal sleep duration of seven to eight hours a night; difficulty falling asleep no more than two times a week; trouble staying asleep no more than two times a week; not using any sleep medication; and feeling well rested after waking up at least five days a week.
Participants were given a score of zero or one for each criteria depending on whether they met it, with a maximum of five points.
Factors that might have increased people’s likelihood of dying were controlled, such as lower socioeconomic status, smoking and alcohol consumption and other medical conditions.
Those who hit all five criteria were 30 percent less likely to die for any reason, compared to those who met none or one of the sleep habits.
The top sleepers were also 21 percent less likely to die from cardiovascular disease, 19 percent less likely to die from cancer.
They were also 40 percent less likely to die of causes other than heart disease or cancer.
Dr Frank Qian, physician at Beth Israel Deaconess Medical Center and study co-author, said these other causes are likely to be accidents, infections or neurodegenerative diseases including dementia and Parkinson’s, but added that more research is needed.
Limitations of the study included the fact that the sleep habits were self-reported.
There was also no information available about the kind of sleep medication patients were using or how long for.
The full results will be presented in New Orleans at the American College of Cardiology and World Heart Federation joint conference between 4-6 March.
