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.
经常接触寒冷因素——冷水游泳或冰泳以及冷空气——会导致人体产生多种适应机制，从而提高对寒冷的耐受性。由于缺乏关于极低室外温度对人体循环系统功能影响的科学报告，本研究旨在评估多次创造世界纪录保持者瓦列里安·罗曼诺夫斯基（Valerjan Romanovski）在芬兰北部罗瓦涅米（ Rovaniemi ）的 50 天内暴露于-5°C 至-37°C 的极寒环境下的全血细胞计数和生化血液指标。瓦列里安·罗曼诺夫斯基（Valerjan Romanovski）证明了人类可以在极寒温度下正常运作。在探险前后采集了受试者的血液。结果发现，以下血液指标异常：睾酮增加 60.14%，红细胞减少 4.01%，血红蛋白减少 3.47%，白细胞减少 21.53%，中性粒细胞减少 17.31%，血小板分布宽度增加 5.31%，天门冬氨酸氨基转移酶增加 52.81%，丙氨酸氨基转移酶增加 68.75%，肌酸激酶增加 8.61%，总胆固醇减少 5.88%，高密度脂蛋白增加 28.18%。其他全血细胞计数和生化指标的百分比变化均在标准范围内。受试者（50 天）长期暴露于极端寒冷应激下，对日常功能没有明显的负面影响。
