Why do people sleep?

Sleeping is a physiological reaction, a part of brain nerve activity, and the result of inhibition of nerve cells in cerebral cortex after continuous excitement. When inhibition is dominant in the cerebral cortex, people will sleep. In life, people have work and rest, and in neural activities, people have excitement and inhibition. Inhibition is to protect nerve cells, make them excited again and let people continue to work.

Sleep is also a process of memory cell metabolism. Aging cells input the arrangement of each memory information into new cells for storage.

Including sports, language areas, balance keys, some past events and memories in daily life.

They are all material, so they also exist in a material way. If a person's long-term lack of sleep leads to the inability of memory cells to live healthily, it is easy to make mistakes, such as aphasia, spasm, convulsion, or shock and fainting caused by forced sleep. It is easy to get cancer after a long time.

Therefore, purely from the perspective of natural science, it is best to wake up naturally, otherwise you will lose your life. A regular life is a good foundation, but long-term fatigue for the sake of "regularity" is dangerous. Scientists suggest that people with financial ability had better let nature take its course, and don't damage their health just to flaunt morality.
