Abstract：
Regular exposure to a cold factor-cold water swimming or ice swimming and cold air-results in an increased tolerance to cold due to numerous adaptive mechanisms in humans. Due to the lack of scientific reports on the effects of extremely low outdoor temperatures on the functioning of the human circulatory system, the aim of this study was to evaluate complete blood count and biochemical blood indices in multiple Guinness world record holder Valerjan Romanovski, who was exposed to extremely cold environment from -5 °C to -37 °C for 50 days in Rovaniemi (a city in northern Finland). Valerjan Romanovski proved that humans can function in extremely cold temperatures. Blood from the subject was collected before and after the expedition. The subject was found to have abnormalities for the following blood indices: testosterone increases by 60.14%, RBC decreases by 4.01%, HGB decreases by 3.47%, WBC decreases by 21.53%, neutrocytes decrease by 17.31%, PDW increases by 5.31%, AspAT increases by 52.81%, AlAT increase by 68.75%, CK increases by 8.61%, total cholesterol decreases by 5.88%, HDL increases by 28.18%. Percentage changes in other complete blood count and biochemical indices were within standard limits. Long-term exposure of the subject (50 days) to extreme cold stress had no noticeable negative effect on daily functioning.
摘要：
经常暴露于寒冷因素-冷水游泳或冰上游泳和冷空气-由于人类的许多适应机制而导致对寒冷的耐受性增加。由于缺乏关于极低的室外温度对人体循环系统功能影响的科学报告，这项研究的目的是评估多项吉尼斯世界纪录保持者ValerjanRomanovski的全血细胞计数和生化血液指标，在罗瓦涅米（芬兰北部的一个城市），他在-5°C至-37°C的极冷环境中暴露了50天。ValerjanRomanovski证明了人类可以在极端寒冷的温度下工作。在探险之前和之后收集受试者的血液。受试者被发现有以下血液指标的异常：睾酮增加60.14%，红细胞减少4.01%,HGB下降3.47%,白细胞减少21.53%,中性粒细胞减少17.31%,PDW增加5.31%,AspAT增长52.81%,AlAT增长68.75%，CK增加8.61%，总胆固醇下降5.88%,HDL增加28.18%。其他全血细胞计数和生化指标的百分比变化在标准范围内。受试者长期（50天）暴露于极端寒冷的压力对日常功能没有明显的负面影响。
