Abstract
The purpose of this paper is to examine the part to warm effective for the improvement of the cold in winter. The experiments were conducted in a climate chamber. The subjects using the heat- and steam-generating sheet were exposed in 25℃ for 60 minutes. We warmed up each physical part (neck, lower back, abdomen, upper arm, fingertips, calf, and tiptoe). Relative humidity kept up 50% constant, air velocity was still air. The subjects were women's college students who are cold constitution. The results were as follows. In winter, by using in a neck, the skin temperature of each part was high and its skin temperature difference was the smallest. And by using in a neck, thermal sensation of body each part had many warm sides, and they were the most comfortable. The improvement of the cold was recognized by using in a neck or the lower back.
