Core Tip: Brushing Weibo in the past few days, did you also see the relationship between “sleep time” and “death risk rate”?

Sleep time and mortality table

Influential but not directly proportional

Regarding the relationship between sleep time and the risk of death, there have been many large-scale surveys in foreign countries over the past 10 years, and the conclusions are basically the same: adults have the lowest mortality rate of 7 hours a day.

Dr. Hu Jun from the Department of Neurology of Southwest Hospital said that there is no relevant specific statistics in China.

"The conclusions drawn from large-scale and long-term investigations and studies abroad are of great significance, but they are only a phenomenon that is statistically stated and cannot be directly used as a scientific basis." Hu Jun said that the sample of the investigation In terms of it, a considerable number of people may have diseases or sleep disorders, which will affect the final statistical results, and the medical significance remains to be studied.

"I believe that the length of sleep will have a certain impact on people's longevity, but there is no direct proportional relationship. In addition to sleep time, a person's genetic and physical quality factors are also closely related to the length of life."

Sleep quality is more important than sleep time

Li Zhifu, a professor of endocrinology at the First Affiliated Hospital of the First Affiliated Hospital, believes that this relationship between "sleep time" and "death risk rate" has some truth, but it is not absolute and will vary from person to person. “Some people can be energized with only 6 hours of sleep, and some people need to sleep for 7-8 hours to maintain their energetic energy.” Relatively speaking, the former has better physical function than the latter, and in the same case, death The rate will be lower and live longer.

Both experts believe that the quality of sleep is more important than human sleep. As long as you can fall asleep quickly, wake up, energetic, is a good sleep, there is no need to adjust your sleep time according to this map.

Experts pointed out that in general, doctors recommend that normal adults sleep 6 to 8 hours a day. “People over the age of 60 need 5 to 6 hours of sleep per day; teenagers or infants need to sleep more than 10 hours a day; and adults sleep no less than 6 hours a day.”

Medically, it is believed that the daily sleep time of adults is less than 6 hours and too short. If it is too long, it will affect the body function.

According to legend, the Song Dynasty Taoist Chen Yu was known as Sleeping Fairy, and he created the horizontal sleeping practice. He lived in Huashan in his later years and lived 118 years old. His secrets are as follows:

Remember, sleep at 23 o'clock is the last bottom line of sleep time. Li Zhifu, a professor of endocrinology at the First Affiliated Hospital, said that the sleep time that can achieve better sleep quality is from 9:00 to 11:00 pm. During this period, the human body's energy decreased, the response was slow, and the thinking slowed down, which helped people to switch to slow wave sleep.

The best sleep time is from 11:00 pm to 6:00 pm, and from 11:00 pm to 3:00 pm is the golden time of sleep. At this time, the metabolism of the liver is the most vigorous. If you miss this golden time of sleep for a long time, sleep disorders will occur, leading to disordered bodily functions.

Those who like nightlife or have to work overtime, often falling asleep at 1 or 2 o'clock in the morning, are the first targets of illness and aging, even if you don't notice it for a while.

"Remember, falling asleep at 11 o'clock is the bottom line of sleep time."
