I know you must want to emphasize: Oh, my head hurts when I do the problem. Isn't thinking so hard consuming brain cells? Actually, it's not. Let me give you a simple example, and you will understand. Take fitness as an example. If you want to make your muscles stronger, you must train very hard, right? In fact, the process of solving problems is like muscle training. The harder the problem, the more you can exercise your brain and be smarter.

This is the conclusion reached by scientists. When you are doing a difficult problem, it is precisely when brain cells are most active. You may not think that the more difficult the topic is, the more connections between brain cells will be established. This connection has a technical term called "neural pathway", which is used to develop your brain and enhance your brain power, thus helping you think more smoothly.

Do brain cells never die? No, there are two kinds of brain cell death: natural death and accidental death. The first kind, natural death, means that whether you are using your brain or not, brain cells will "leave you", which is a normal human development phenomenon.

Do you know that when you are born, the number of your brain cells will reach more than 654.38+000 billion? Only after birth will the number of brain cells begin to decline, because the brain will automatically destroy those brain cells that have not been used for a long time, and the brain cells that are often used will become more and more active. A cell biologist has specially studied and estimated that after the age of twenty, everyone will lose at least 9,000 brain cells every day. Of course, the premise is that you take good care of yourself and don't let your brain cells die unexpectedly.

Many bad living habits and behaviors will make brain cells die unexpectedly. For example, persistent insomnia will kill brain cells. You think, if you can't sleep for a long time, your brain won't get energy supply when you rest, and cells will die. In addition, there is smoking. You know, there are about 7,000 kinds of toxic chemicals in smoke, some of which affect the brain specifically. In addition, prolonged hypoxia will directly lead to brain cell death, such as fire and drowning.
