Means of setting the tropical rainforest environment based on the activation characteristics of the human brain stem to the tropical rainforest environmental data is provided in an urban space, a living space or another life space to thereby set the tropical rainforest environment in the space. Thus, an environment being capable of activating the human brain stem and not harmful to the human brain can be established. The tropical rainforest environmental data has a high density and a high complexity compared with the urban space environmental data, and involves at least one of auditory data, visual data and supersensory data of air vibration. The environment not harmful to the human brain means an environment which is pleasant for human beings and free from any excessive stress. The tropical rainforest environment is an environment which is to be established in order to efficaciously practice the prevention and treatment for diseases caused by stress. |
