Gu Ailing once mentioned in a public speech that his secret weapon is to "sleep enough for 10 hours a day."
As long as we sleep for 10 hours a day, we can also go to the peak of life like Gu Ailing? Is there any scientific rationale for this "secret weapon" she is talking about? Can we follow suit?
In fact, if you study Gu Ailing's original words carefully, she was asked by her mother to sleep for 10 hours when she was 8-14 years old. According to scientific studies, children aged 10-13 need more than 9 hours of sleep per night. However, adults in their 20s need less sleep time than adolescents who need to grow and develop, only 7-8 hours.
Will there be an added benefit for adults in their 20s, who also sleep 10 hours a day?
The answer is, not necessarily! Sleeping too little or too much can be one of the manifestations of some health risks. If there are some problems with the human body, it may be reflected in the length of sleep.
For normal adults, the gold standard for how long you sleep is not a thin number. Instead, it is to see if you have enough energy during the day, so that you are not easy to get sleepy.
