日本人成人女子の体温調節反応における暑がりと寒がりの比較

The purpose of present study was to observe the differences of thermoregulatory responses between atugari (=susceptible to the heat) and samugari (=susceptible to the cold). The subjects were 12 healthy young Japanese adult women (age: 21.8±1.7yrs, stature: 160.5±7.8cm, weight: 49.6±7.5kg, BMI: 19.2±2.4). They put on shorts, T-shirts and short pants. Exposure periods were evening (E) and morning (M) during follicular phase (F) and luteal phase (L). The climatic chamber was controlled at 24℃ RH50%, the temperature increased to 29℃ over 60 minutes gradually. The subjects kept the sitting position. Measurement items were rectal temperature (Tr), skin temperature and subjective sensations. We determined atugari and samugari according to the subjective sensations during exposure. The main results were as follows. 1) The order of values of Tr and mean skin temperature was L・E>F・E>L・M>F・M. 2) The theromoregulatry responses were more influenced by circadian rhythm than menstrual cycle. 3) The order of skin temperature of hand and foot was E<M. 4) Atugari had a tendency to feel warm in the peripheral area and to feel cool in the body stem area than samugari.
