I once read an article at leisure, saying that scientists found that many of people's feelings and perceptions come from the stomach, and there is a very complicated neural network in the stomach. 95% of the neurotransmitters in the human body-serum-based-are produced in the abdomen. This nervous system can store a lot of information and retrieve it when needed, just like an archive. Therefore, scientists call the abdomen the second brain of the human body.
My heart failed when I saw this. I am once again proud of being a China native and proud of the ancient civilization created by our ancestors. Look at our idioms, talented and learned people are praised as "knowledgeable"; People who do many evils are called "full of bad water"; An illiterate person, we call him "gluttonous" ... Look at these, obviously they are closely connected with the brain, but in idioms they are all connected with the stomach. It can be seen that our ancestors never regarded the abdomen as an empty container, but thought that all human knowledge and wisdom were hidden in the abdomen.
The stomach is so important that it not only contains internal organs, but also is the dense place where meridians and qi and blood run. Huangdi Neijing says that the abdomen is "the palace of internal organs, the source of yin, Yang Qi and blood". Actually, it's more than that. The abdomen is also the concentration of wisdom and emotion and the "second brain" that dominates people's thinking.
Speaking of the abdomen as the second brain, many people may wonder: If so, what does the brain need to do? This is a little deeper, and it is related to the origin of species. As we know, the original creatures only had ventral brains, but no brains. In the process of species evolution, the function of ventral brain gradually became insufficient, so the brain came into being. Just like when we are alone, we can live in any small attic, but when we get married and have children, the small attic becomes crowded, and the spacious big house enters the life plan. If there is not enough abdominal brain, the brain will sprout to guide the daily operation of human organs.
The function of the brain is so powerful that we all forget that there is such a "belly brain" hidden in the depths of the human body. However, the ventral brain did not disappear because it was ignored. Although it is willing to be lonely, it will remind people not to forget its existence at an appropriate time. For example, patients with gastrointestinal diseases always feel confused and often have nightmares, making it difficult to sleep well. This is the abdominal brain telling the brain through the meridians that its "body" is uncomfortable. An obvious example is that you ate a delicious food several years ago, and after many years, you still remember it. When you see that thing, you will have a strong desire to taste it. This is actually the memory function of the abdominal brain.
Speaking of which, I don't know if you have such an idea. If we develop the function of belly brain, wouldn't we have a "dual core" like a computer now? Needless to say, scientists are really studying. There is an introduction at the bottom of that magazine, saying that experts have tried to develop abdominal brain through ancient exercise methods.
Playing Tai Ji Chuan often is good for abdominal health, preferably outdoors with fresh air.
Speaking of which, I'm going to snicker again. They thought about it, and the way they found was Taiji Chuan. Also, what other method can be as suitable for all ages as Tai Ji Chuan, with simple movements, but it can go deep into the viscera and stimulate the most hidden abdomen? Tai Ji Chuan's first step is to "sink qi into the abdomen". He points directly at the abdomen, so that qi is injected into the abdomen, which will drive the abdominal viscera to operate. These viscera transmit information and communicate with the brain through neural networks. Then every step, every movement, every gesture, every movement is centered on the waist and abdomen. I think Tai Ji Chuan is the most ready-made and effective choice to develop the "belly brain".
We used to say that a person is very smart and can always use his quick wits, and that he has a plan with a frown, which means that he can come up with a plan with a frown. If the ventral brain is developed, it is estimated that one day, when we say that a person is very intelligent, we may look at his abdomen and become "a bulging belly, and the plan will come to mind"!
