What is the most common sentence we have heard since childhood? God's fairest to people is time, and everyone is 24 hours? . Naive, we believe in it, and when we grow up, we find that even time is unfair. Some people are still groggy after sleeping for eight hours every day, and some people are as energetic as nothing happens after sleeping for four or five hours. So from the beginning, we stood on different starting lines.

Fu Seoul once joked in "Qipa Shuo":? Since I came to the program group "Strange Fear", I discovered that people can't sleep? . Therefore, under the impetus of strong work, people can really resist drowsiness by perseverance. But in addition to one's own willpower, the human body's own factors will also affect the degree of sleepiness.

According to scientific research, if a specific gene in the human body mutates, it can reduce people's sleep time, while people without mutation need longer rest time. The research results were first published in the journal Science, and then new genes related to sleep were discovered one after another, further revealing the deep factors affecting sleep time.

Like what? 1 adrenergic receptor, people with mutations can be energetic as long as they sleep for 6 hours every day, and there is no adverse effect. However, if people without mutations rest for the same time, they will be emotional because of lack of sleep, which is potentially harmful to health.

So don't worry about why some people can still be happy after sleeping for a few hours every day. This is a natural decision. However, it is not normal to be too sleepy. Breathe more fresh air, strengthen exercise, and let the brain have enough oxygen supply.

In addition, improving the quality of sleep can also make people recover faster. The first is to adhere to a regular schedule. Living without a fixed address can easily cause physical problems. Secondly, creating a well-ventilated and clean sleeping environment is more conducive to falling asleep. Finally, don't play mobile phone for too long before going to bed, which will easily excite people's brains and reduce the quality of sleep.
