Think about the experience process of having negative emotions through the experience of a disaster. In the process of experiencing a disaster, the body grasps the situation of the disaster with the five senses, feels the situation, and thinks about the process that is scarier than the situation. When a disaster occurs, the human body senses the disaster situation through all the sense organs of the five senses (external acceptance) and the sense of balance (self-acceptance). Information captured by the sensory organs is transmitted to the brain through sensory nerves and processed. It is transmitted to each organ of the body through the nervous system and blood flow, and it is judged and felt by visceral sensation (internal acceptance). People instantly collate the information read the sensory organs with past experiences and start preparations and make decisions so that they can detect and judge dangers. Affects are automatically generated by a beast-like judgment called the old brain. If it is determined to be dangerous at this stage, an escape reaction will occur, and the action will be lifesaving. This escape reaction is a reaction that is executed by judging whether to fight instantly, escape, or be in awe. In parallel with this escape reaction, the body undergoes a process of generating emotions.
Feelings for the slowly felt sensation gradually develop. From the bodily sensation information transmitted to each organ of the body, each organ will feel scared by the comprehensive judgment. It generally takes 2 to 20 seconds from a negative experience to feel scared. It takes a considerable amount of time for a person to be recognized by such scary emotions. The process of obtaining a feeling of scary is transmitted to each organ of the body by two systems, a system that transmits hormones to each organ of the body at high speed through the nervous system and a system that transmits hormones through blood vessels by hormone secretion and generates comprehensive emotions. Finally, the brain recognizes it. These are the states that have been comprehensively judged through a very advanced process. In addition, if the degree of fear during the experience is high, the experience and the situation will be recorded as information on the body together with the captured results. When accompanied by a strong fear (when you feel the danger of life and imagine death), it is not a good situation for humans, but it may be recorded as a mental disorder. These experiences are memorized in the body as life-threatening experiences, and it seems to be a mechanism that is passed down to future generations as essential information that makes the later life cycle work effectively. In order to improve the risk sensitivity due to the disaster experience that we are developing, the experience software considers these processes and sets a biological danger limit in the experience process so as not to cause mental disorders, and damage during the experience. It is necessary to design in consideration of. It is necessary to understand the biological mechanism of human beings and always take the utmost care not to cause mental disorders while touching emotions.
