Sensitivity to cold (hiesho) is a serious health problem in Japan, yet it is minimally understood within Western cultures. The purpose of this study was to clarify the divergence between pregnant Japanese woman living in Japan and pregnant Brazilian women living in Brazil in awareness of hiesho and differences between core body and peripheral temperatures.
The subjects of this study were 230 pregnant Japanese women living in Japan and 200 pregnant Brazilian women living in Brazil. Data was collected in June/July and November 2005 in Japan and from October 2007 to February 2008 in Brazil. The survey methods consisted of measurement of deep body temperatures and questionnaires.
67.0% of Japanese women and 57.0% of Brazilian women were aware of hiesho, which showed a significant difference between the Japanese and Brazilian women (p = 0.034). The difference between forehead and sole temperatures was 2.0°C among Japanese and 2.8°C among Brazilians in June-July (p = 0.01). But in November the difference between those temperatures was 5.2°C among Japanese and 2.8°C among Brazilians (p < 0.001).
There are differences between Japanese and Brazilians both in awareness of hiesho and in body temperatures.
对寒冷敏感（畏寒）在日本是一个严重的健康问题，但在西方文化中对此了解甚少。本研究的目的是阐明居住在日本的日本孕妇和居住在巴西的巴西孕妇在畏寒意识以及核心体温与外周体温差异方面的不同。
本研究的对象是230名居住在日本的日本孕妇和200名居住在巴西的巴西孕妇。2005年6月/7月和11月在日本收集数据，2007年10月至2008年2月在巴西收集数据。调查方法包括测量深部体温和问卷调查。
67.0%的日本女性和57.0%的巴西女性知晓畏寒，这表明日本女性和巴西女性之间存在显著差异（p = 0.034）。6月至7月期间，日本女性额头和脚底的温差为2.0°C，巴西女性为2.8°C（p = 0.01）。但在11月，日本女性的温差为5.2°C，巴西女性为2.8°C（p < 0.001）。
日本人和巴西人在畏寒意识和体温方面均存在差异。
