Many people think that sleeping more is good for the body and can even prolong life. However, the latest research by some scientists suggests that sleeping too much can lead to "early death". Even the once-recognized "8 hours of sleep a day" can have the effect of reducing longevity.

Recently, researchers at the University of California in the United States have come to the latest conclusion after observing more than 1 million adults: those who sleep more than 8 hours a day and less than 4 hours will have their life expectancy shortened to varying degrees. And people who sleep within 6 to 7 hours a day live the longest.

For this reason, scientists propose that six and a half hours of sleep a day is enough for adults in good health. From a health point of view, too much sleep is completely unnecessary. Horn, a professor at the Sleep Research Centre at Loveborough University in the United Kingdom, also pointed out that for a long time, those who thought that sleeping more was good for their bodies were actually misguided.
