For the human body, a standard that can keep the body running is body balance. If a person does not eat, sleep or excrete, then this person's body will not be balanced, which will inevitably lead to extinction and eventually disappear!
People need sleep, mainly because in the state of sleep, the organs of the body can be at rest, thus preparing for the resurrection of the body.
If a person doesn't even have time to sleep, it's a pity that his body has no chance to be in a state of repair. Like our generator, it can't run forever. This does not conform to the law of conservation of energy in nature and is doomed to be unrealistic.
As a person, if you don't eat, then you have no energy. According to the law of conservation of energy, if you want to engage in a certain job, you must pay the corresponding energy. Only in this way can you get what you want. But if you don't eat, your body has no energy consumption at all, which is naturally unrealistic.
Extended data:
People's normal sleep is seven hours.
The figure of seven hours is based on the study of sleep habits of people who live longer. People who don't suffer from diabetes, heart disease and cancer usually control their sleep time to about seven hours, so the researchers concluded that seven hours may be a "magic" number.
A few days ago, the Wall Street Journal reported that a study on the sleep habits of people who live long showed that seven hours' sleep may be the most beneficial to their health. It is generally believed that seven to nine hours of sleep is inaccurate, and long-term sleep over eight hours is not good for your health.
