摘要

本文定义了功能性寒冷暴露区,以说明一个人是否有身体机能丧失或寒冷天气受伤的风险。身体特征、活动水平、衣服和防护设备的个体差异都会导致有效暴露的变化。然而,如果有正确的教育、训练和适应寒冷的行为,暴露差异可能不一定会增加冷损伤的风险。为了支持寒冷天气作业的准备过程,本文提出了一项生物物理分析,解释了在同一环境中,不同个体的寒冷暴露风险有多大。研究结果表明,体型较小的人在中等活动水平下容易穿着不足,而体型较大的人则容易穿着过度。这些差异的后果使人们面临不同的表现损失或寒冷天气受伤的风险。尽管如此,即使所有人都在全身水平上穿着得体,手部形态的变化也会影响可以保持的手部皮肤温度;较小的手更容易达到与灵活性丧失或寒冷天气损伤相关的皮肤温度。总之,这项工作的重点是将寒冷科学带给北极战士,证明对抗寒冷压力不是一种一刀切的方法。

We are all exposed, but some are more exposed than others.

This paper defines functional cold exposure zones that illustrate whether a person is at risk of developing physical performance loss or cold weather injuries. Individual variation in body characteristics, activity level, clothing and protective equipment all contribute to variation in the effective exposure. Nevertheless, with the right education, training, and cold-adapted behaviours the exposure differences might not necessarily lead to increased risk for cold injury. To support the preparation process for cold weather operations, this paper presents a biophysical analysis explaining how much cold exposure risk can vary between individuals in the same environment. The results suggest that smaller persons are prone to be underdressed for moderate activity levels and larger persons are prone to be overdressed. The consequences of these discrepancies place people at different risks for performance loss or cold weather injuries. Nonetheless, even if all are well-dressed at the whole-body level, variation in hand morphology is also expected to influence hand skin temperatures that can be maintained; with smaller hands being more prone to reach skin temperatures associated with dexterity loss or cold weather injuries. In conclusion, this work focusses on bringing cold science to the Arctic warrior, establishing that combating cold stress is not a one size fits all approach.

期刊介绍: The International Journal of Circumpolar Health is published by Taylor & Francis on behalf of the Circumpolar Health Research Network [CircHNet]. The journal follows the tradition initiated by its predecessor, Arctic Medical Research. The journal specializes in circumpolar health. It provides a forum for many disciplines, including the biomedical sciences, social sciences, and humanities as they relate to human health in high latitude environments. The journal has a particular interest in the health of indigenous peoples. It is a vehicle for dissemination and exchange of knowledge among researchers, policy makers, practitioners, and those they serve. International Journal of Circumpolar Health welcomes Original Research Articles, Review Articles, Short Communications, Book Reviews, Dissertation Summaries, History and Biography, Clinical Case Reports, Public Health Practice, Conference and Workshop Reports, and Letters to the Editor.
