Infrared phenomena under the qigong state and blood vessel volume Author: Chen Wenhua//Chai Jianyu Affiliation: Shanghai Qigong Institute, Shanghai 200030, China [1] Conference/Journal: 2nd World Conf Acad Exch Med Qigong Date published: 1993 Other: Pages: 86 , Word Count: 186 Infrared phenomena under the the Chen Wenhua qigong state has been researched for more than ten years. This thesis, on the basis of the research, first studies the infrared phenomena under the qigong state on physiological theory, and discusses the relationship between the infrared phenomena under the qigong state and the changes of vessel volume. In order to study the relationship between the changes of the infrared temperature under the qigong state and the changes of digital vessel volume, we observed 192 volunteers' change of infrared temperature and vessel volume from the pre-qigong state to post-qigong state at the same time. All results indicate that the changes of the infrared temperature under the qigong state were related to the changes of partial vessel volume. It also means that the vessel volume increaces while the infrared temperature is rising. There might be the relationship of cause and result between the two items. Since the skin temperature and digital vessel volume are affected by many factors including influence of personality, the further research will be done on the basis of the development of experimental techniques and more experimental samples.
