In winter, many people have trouble with chilliness in their arms and legs. Many women are especially sensitive to cold, and for them the chilliness of the hands and the feet is difficult to ease even after entering a warm room, or taking a bath. They even feel pain owing to coldness of their limbs in daily life. This symptom has been called “hiesho” in Japanese.The problem of this chilliness is difficult to study because this symptom, in general, can be cured when spring comes. Coldness of the limbs has been considered to be one of the symptoms of the climacteric disturbance among middle-aged females.Recently, however, it was reported that many young females also feel pain owing to coldness of the hands and legs in their daily life during winter.This study investigates the problems of chilliness in the limbs of young females in their daily life. By means of a questionnaire, 642 female college students aged from 18 to 20 years answered questions concerning: (1) physical characteristics, (2) physical conditions in their daily life, (3) physical conditions in winter, and (4) physical conditions in summer. The replies to the questionnaires were tested using the χ2 test.The major results were as follows:1. Half of the subjects were sensitive to cold, and had difficulty sleeping owing to chilliness of their limbs in winter even in a warm environment.For the following results the subjects who were sensitive to cold had significant differences (p<0.05) compared to non-sensitive subjects to cold.2. Those subjects who were aware of chilliness in their limbs had high prevalence rates for irregularities in circadian body rhythm, as well as some symptoms such as white fingers phenomenon, numbness of their limbs, and stiffness in their hands.3. The subjects who were aware of chilliness in their limbs were very sensitive to cold in winter, and had female family members who had the same troubles with chilliness in the arms and the legs, too.4. The subjects who were aware of chilliness in their limbs were sensitive to cold even in summer, and had difficulty sleeping owing to chilliness of the limbs.

女子短大の学生を被験者に3週間にわたり,テストステロンの濃度と,リスク選好指標,時間選好などを計測した.リスク選好指標は,選択課題(choice task)と適合課題(matching task)の2種類を用いた.また被験者のT濃度を,グルコース投与によって一時的に低下させて,コントロール群との違いを見た.結果,Tの絶対濃度とリスク選好には選択課題,適合課題ともにはっきりとした関係がなかった.また,30分間隔でのT濃度の変化と,リスク選好の指標である 選択課題の間には有意な正相関があるが,選択課題とでは有意性は示されなかった.T濃度の変化は,確率過程の不明な不確実性(uncertainty)状況では影響を与えるが,確率過程が既知のリスク(risk)状況下では弱い,あるいは与えないことが示唆された.またTは時間選好には影響を与えない.
