Harvard: Good sleep can extend your life by almost 5 years.
Sleep is a restorative process in the body that restores energy and relieves fatigue. During a person’s life, about one-third of the time is spent in sleep. Good sleep is one of the three health standards recognized by the international community, and too short sleep time or poor sleep will affect health.
In China, more than 300 million people suffer from sleep disorders, the incidence of insomnia among adults is as high as 38.2%, and over 90% of primary school students do not sleep up to the standard. rising.
In today’s society, staying up late has become the new normal for many young people. Staying up too late can be very damaging to your body, and lack of sleep is known to be associated with an increased risk of cardiovascular disease, depression, diabetes, high blood pressure, and overall mortality.
Recently, researchers at Harvard Medical School in the United States published a study at the upcoming “American College ” annual scientific meeting.
Studies have shown that good sleep habits can increase life expectancy by 4.7 years for men and 2.4 years for women. Compared with people with 1 good sleep factor, those with 5 good sleep factors had a 30% lower risk of death from any cause, a 21% lower risk of death from cardiovascular disease, a 19% lower risk of death from cancer, and a 19% lower risk of death from heart disease 40% less likely to have causes other than disease or cancer .
In the study, the researchers analyzed 172,321 people who participated in the National Health Interview Survey between 2013 and 2018. The average age was 50 years old, and 54% were women. A study of how several sleep behaviors affect life expectancy by using a nationally representative population.
Based on the answers collected in the survey, five different factors affecting sleep quality were assessed:
- 7-8 hours of sleep per night
- Difficulty falling asleep no more than twice a week
- Insomnia no more than twice a week
- no sleeping pills
- Waking up feeling well rested at least five days a week
One point for each sleep quality factor, up to five points, indicating the highest quality sleep.
During a mean follow-up of 4.3 years, 8681 deaths were recorded, including 2610 from cardiovascular disease, 2052 from cancer and 4019 from other causes.
Compared with people with 0-1 good sleep factors, those with 5 had a 30% lower risk of all-cause death, a 21% lower risk of cardiovascular disease death, a 19% lower risk of cancer death, and a 19% lower risk of death from cardiac causes, the study found . 40% less likely to have causes other than disease or cancer, including infections, neurodegenerative diseases, and more .
In addition, men with 5 good sleep factors had a 4.7-year increase in life expectancy and women with 5 good sleep factors had a 2.4-year increase in life expectancy compared with those with 0-1 good sleep factors .
The researchers say these findings underscore that it’s not enough to just get enough sleep, you really have to be getting restful sleep and not having too much trouble falling asleep and staying asleep. If we could improve sleep overall, it would greatly benefit overall health and perhaps prevent some premature deaths.
In summary, studies have shown that good sleep is particularly important, not only can reduce the risk of death, but also prolong life.
