Sleep time and mortality comparison table

The relationship between sleep duration and mortality risk

Over the past decade, there have been many large-sample surveys conducted abroad, and the conclusions reached are basically the same: adults who sleep 7 hours a day have the lowest mortality rate.

“These conclusions drawn from large sample sizes and long-term research abroad are of great significance, but they are only statistical phenomena and cannot be directly used as scientific evidence.

Experts said that in terms of the survey samples, a considerable number of people may have diseases or sleep disorders, which will affect the final statistical results. The medical significance of this remains to be studied.

"I think the length of sleep will have a certain impact on a person's lifespan, but there is no direct proportional relationship. In addition to sleep time, a person's genes, physical fitness and other factors also have a great relationship with the length of lifespan."

Sleep quality is more important than sleep quantity

This chart showing the relationship between "sleep time" and "mortality risk" makes some sense, but it is not absolute and depends on the individual. "Some people only need 6 hours of sleep to be energetic, while others need 7 to 8 hours of sleep to maintain strong energy." Relatively speaking, the former's physical functions are stronger than the latter. Under the same circumstances, the mortality rate will be lower and they will live longer.

Sleep quality is more important to human health than sleep duration. As long as you can fall asleep quickly and wake up feeling energetic, it is a good sleep. There is no need to adjust your sleep time according to this relationship chart.

Generally speaking, doctors recommend that normal adults sleep 6 to 8 hours a day.

"People over 60 need 5-6 hours of sleep a day; teenagers or infants need more than 10 hours of sleep a day; and adults need no less than 6 hours of sleep a day."

Medically speaking, if an adult's daily sleep time is too short, less than 6 hours, or too long, more than 10 hours, it will have a certain impact on the body's functions.

Sleep time

I recommend a sleeping position, you can try it: According to legend, Chen Tuan, a Taoist priest in the Song Dynasty, was called the Sleeping Immortal. He created the unique method of practicing lying sleeping skills. He lived in seclusion in Mount Hua in his later years and lived to be 118 years old. Here are his tips:

Remember, going to bed at 23:00 is the bottom line of sleep time.

The best time to go to bed and get better sleep quality is between 9pm and 11pm. During this period, the human body's energy decreases, reactions become slow, and thinking slows down, which helps people enter slow-wave sleep.

The best sleeping time is from 11pm to 6am the next day

The golden time for sleep is from 11pm to 3am the next day. The liver's metabolism is most active at this time. If you miss this golden sleep time for a long time, you will suffer from sleep disorders, leading to body dysfunction.

Those who like nightlife or have to work overtime and often fall asleep at 1 or 2 in the morning are the pioneers of disease and aging, even though you cannot notice it for the time being. "Remember, going to bed at 11 o'clock is the bottom line of your sleep time."
