Temperature and Biophoton Changes of the Middle Finger during Qigong and Light Imagery Tasks(<Main Topics>Human PSI Forum "Human Potential Science" International Forum : Physical and Physiological Approach Joint with "Mystery of Mind and Body" International Forum and The Fourteenth Symposium on Life Information Science (International Version) 22-27 August 2002, OVTA, Makuhari, Chiba (near Tokyo), Japan)

Abstract

The authors have previously measured physiological changes for subjects during Qigong and light imagery tasks. A skilled Qigong trainer's skin surface temperature of the middle finger decreased during Qigong compared with the value at rest measured by thermography. Moreover, the biophpoton count radiated from the middle finger increased during light imagery task compared with the count at rest measured by PMT. In the present study, a beginner in Qigong and non-trained subjects performed the same experiment. The beginner had a remarkable increase of skin surface temperature of the middle finger during Qigong compared with the temperature at rest (maximum difference was 3.3 ℃, P=0.046<5% in a two-sided t-test), and an untrained female showed her middle finger radiated more biophotons when she did a light imagery task. These results suggested that skin temperature and physiological metabolism might be influenced by Qigong and light imagery tasks.
