The effect of menstrual cycle phase on foot skin temperature during mild local cooling in young women

摘要

Both young and menopausal Japanese women can experience a sensation of coldness called "hie-sho". Previous studies have shown that the skin temperature (Tskn) of the foot in women with hie-sho decreases in a cold environment. A deficiency and fluctuation in female hormones might be related to hie-sho; however, even in healthy young women, the effect of menstrual cycle phase on Tskn of the foot during local cooling is unknown. Thus, we examined Tskn and partial cutaneous blood flow in the foot duringthe follicular (F) and luteal(L) phases during mild local cooling in healthy young women as a first step in investigating hie-sho.
