Cold constitution is a condition in which the patient feels uncomfortably chilly especially the fingers, legs, and waist. The disease persists for more than a half year. Cold constitution might be mainly related to the disorder of autonomic nervous system and a lack of female hormone. Previously, we reported the relationships between the peripheral circulatory function evaluated by the accelerated plethysmogram (APG) and the cold constitution in female students. The females without the cold constitution (Normal group) belonged to the types of good circulation, and higher APG scores. However, there were many females having the poor circulation and lower APG scores in the females with the cold constitution (Cold group), compared with Normal group. In the present study, the relationships between the wave components (a, b, c, d, and e) of APG and the cold constitution were explored in many young female students. First of all, they were divided into both Normal group and Cold group. The Cold group was further divided into three subgroups (weak, medium, and strong) by the severity. We found that the amplitude of wave component "c" of APG in Cold group was significantly greater than that of Normal group. In addition, the amplitude of component "d" of APG in strong Cold group was also significantly greater than that of Normal group. These findings suggest that the peripheral circulatory function in Cold group may deteriorate, when compared with Normal group, because old people tend to have a bigger amplitude of components "c", "d", and "e" in APG.
