Abstract
In this study, we investigated skin thermosensitivity in 10 female subjects (22.8±2.5 years old) to address various
issues related to air-conditioned environments, focusing on menstrual cycle phase (follicular, ovulatory, luteal)
and related hormones. Warm and cool thresholds in each stage of the menstrual cycle were measured in an experimental
room with air temperature 28°C and relative humidity 50%. It was concluded that cold sensitivity was relatively
low in the luteal phase. Furthermore, the results implied that progesterone affected cold sensitivity, with cold
sensitivity becoming less acute with higher progesterone. However, it should be noted that women have higher skin
thermosensitivity than men, regardless of menstrual cycle phase.
