Abstract
Objective: This study aimed to determine the differences between the core body and peripheral temperatures of young women with hie using deep temperature, and to demonstrate an objective and simple method for hie evaluation. Methods: This study measured the deep body and skin temperatures of 24 young women from July to October 2018. We divided the participants into two groups: a hie group who has awareness of cold sensation and a non-hie group. We compared the deep temperature difference between the forehead and the instep in the two groups. We calculated the ratio of the number of pixels below a specific temperature to the total number of pixels in the instep based on a thermographic image. Results: Nine participants were in the hie group and 15 were in the non-hie group. The deep temperature difference of the hie group was significantly larger than that of the non-hie group (p = 0.030). The temperature difference positively correlated with the ratio of pixels for the temperature distribution ≤ 31.0 ℃ on the instep (rs= 0.869, p < 0.001). Conclusion: Young women with a large deep temperature difference can be simply screened by thermography based on the ratio of the lowtemperature region of the instep.
