Ochiai: The way of forest therapy is very succinct. That is using five senses. It is to release the senses. Can you release the senses at this place now? I think that you can not do it. Listen carefully, look closely with your eyes, feel the smell, also sharpen the skin sensation such as wind flow. You can not do it even if you are told to do it in this environment now. It can be done when going into the forest. The point is that environment. In other words, entering into the forest can make the five senses work at the same time. Then you can hear various sounds and smell a lot, you can do various things at the same time. What we can do is to have five senses open at the same time. That's why stress is released. It is impossible to do so in an artificial environment. That is forest therapy. To say extremely in short, it is that kind of thing.
Ochiai: Just to do that, the medical effect you said earlier emerges.For example,it is amazing that immunity will improve. If the immune power increases by 30%, 40%, it will become a body that will not catch a cold. Or it can become a body hard to become cancer. It is prevention against various diseases by getting stressed. It includes mental illness.
Ochiai: That is the rule of nature. Even though it was not in a normal state with various stresses until then, but it got becoming in a normal state soon.
Ochiai: When saying the stimulation to the senses received from the forest, sensuousness like mouth seems to be in a special position. When I taste it, I do not understand what the taste is from the forest. It can be understood that eye is related to light,sound is related to ear, smell is related to nose, skin sensation is related to thermal environment etc. However, the relationship between the forest environment and the taste is a bit ambiguous because forest seems to have no taste.
Ochiai: When I think about it, humans body starts from the egg and get out of the intestines. It is the intestines that are first made in our body,then mouth and anus. After all, the structure of a person enters from the mouth and comes out of the anus from the tube structure. So mouth is important as the basic structure of human, not only to eat but also to be the beginning of various cultures and actions. So it is probably the most important thing for children to arrange cuisine and dishes, which is the first step in the code of conduct in human formation and culture. You can say that your mouth is controlling these things.
Ochiai: So preparing meals for children is not an unpleasant task, but rather a fun game and cultural thing. I hope you can link the actions to eat that way to culture.
Ochiai:Ｗe are always under stress. Children also do in the same. The only diseases that have been proven to be caused by stress are listed. Stress is the cause of most diseases. This is not known too much. Everyone has an image of some extent that it becomes a mental illness when there is stress. However, there are many people who do not know that it has influences such as angina pectoris and peptic ulcers. So I think you will understand how important it is to get rid of stress,if you see this table.
Ochiai: This is Meiji Shrine of Tokyo. Such things are in the middle of Tokyo. Humans should originally live in this green part. People should have lived in environmental capsules,such a green capsule. However, We are living in the part that protrudes from there. Then you can see that it is a completely different environment. We feel stressed with this. But everyone can not live in this forest anymore. While living on the protruding side, We have to copy the elements that the green side has. That is the starting point for the idea of forest symbiotic architecture.
Ochiai: What is a forest? What is nature? It is human senses to receive and feel the information of the environment. Therefore, it is easy to understand analyzing the identity of environmental information by dividing it into stimulus signals to the five sensory devices. The most obvious is vision. The forest is full of green light. The reason the leaves are green is because the leaves reflect and transmit the green light in the sun's rays. People who evolved in such an environment feel stressed unless they are as green as possible during the day. When we go to the green place, it feels somewhat pleasant because we are in a state where the genetic structure is oriented.
Ochiai: When thinking about the original human dwelling, it is important to consider how much this green is adopted and how much green light is taken in. However, there is no such idea in contemporary architectural planning. In addition, in terms of important light, in order for human beings to live healthily, we need a mechanism to reset the biological clock every day. For that, blue light in sunlight is necessary. The mechanism to reset the body clock every day by taking a blue light every morning is structured not only in the human body but in all creatures. However, modern dwelling does not have such a function. The light of the sun is used only by the idea of adopting it as energy at the most.
Ochiai: There's one more thing. We turn on electricity as soon as it gets dark in our modern life. It does not happen in the forest. But perhaps our urban environment will be quite bright. This is truly contrary to the natural rhythm. The biological life rhythm and the environmental rhythm conflict.
Ochiai: So in the housing, I think that something like such an interface of light must be secured with considerable importance. When getting up in the morning,blue light will come into your eyes naturally, or in the daytime you must be able to see the green light somehow. And in the evening we can make it dark as it is. Such a construction plan becomes necessary from the viewpoint of light design..
Contact environment and floating feeling Ochiai: The material of the floor is very important. Many people think that they want to make the floor from wood. Actually,the bottom of our feet is always touching to the floor. So the material that touches the back of the foot is very important. Of course I agree to use wood there. At the same time, the stability feeling that the foot stands on the ground surface is also very important. The high rise apartment seems to be popular nowadays, but it is because some sense is becoming insensitive. for person not accustomed to a high place, a distinctive floating feeling is disgusting. After all, floating from the ground does not match the human sense. That is probably a factor of stress. People should not live in more than a tree height(height of the forest) after all.
Static electricity living environment Ochiai: Also, the problem of charging on the human body is serious. It is dangerous to put yourself in the electric field. The environment of artifacts is very charged. There is a potential difference with yourself, and weak current flows constantly in the body. That is our living environment. However, there is no place to be charged in the woods. Since all the electric charge flows on the ground, it is completely neutral in terms of electric potential. In order not to charge the house, do not float the floor with the earth structure. If you do not have space under the floor, you can escape the electrons to the ground so you can prevent the charging environment.
Heat capacity of the soil floor Ochiai: There are lots of other benefits if you also make the soil floor. On the soil floor there is the ability to store the heat that is to say heat capacity. Compared with the ground, the tree building itself has not so much heat capacity. Therefore it is better to store a lot of heat on the ground surface. This heat can be used to make the temperature of the building. Controlling the indoor thermal environment with the building's own body temperature is the most comfortable and healthy way. It is called ground radiant heat environment. Everybody sat on the ground as it was a warm floor in winter. The soil floor is comfortable again because it is cool with the natural temperature in the summer.
Make houses with naturally dried trees Ochiai: We use wooden materials that are natural dry. Since natural drying is not dried with a high-temperature dryer, the tree's life function, such as humidity control function or aroma secretion function and air purification function remains in the tree. Now at a rate of almost 90 percent or more wood is dried at high temperature. Wood that has been dried at high temperature has lost its important life function. Ochiai: You should build a house with trees that are natural-dried and have not lost their original life functions.
