Abstract
Physiology measurements were made to compare effects on the human body when wearing plain polyester cloth and polyester cloth made from fibers containing a special tourmaline powder(AP fibers). The clithing made from AP fibers was effective for heating the human body by a far infrared ray effect. It was understood that the parasympathetic nervous system became dominant based on changes of R point voltage of the ECG and also GSR data, and that the AP fiber had good effects on oxygen concentration and blood pressure.
