Ambient temperature (T _a, a), body core temperature (T _core, b), mean skin temperature (mean T _sk, c), and skin temperatures of the chest (T _chest, d), index finger (T _index, e), and hallux (T _hallux, f) in the follicular and luteal phases. Values are mean ± SE (n = 8). *P < 0.05, significant differences between the follicular and luteal phases; #P < 0.05, significant differences from the baseline value at 0 min in the follicular phase; §P < 0.05, significant differences from the baseline value at 0 min in the luteal phase
