Abstract：
Antarctica provides a unique environment for studying human adaptability, characterized by controlled conditions, limited sensory stimulation, and significant challenges in logistics and communication. This longitudinal study investigates the relationship between stress indicators, with a specific focus on mean sleep heart rate, during a COVID-19 quarantine and subsequent 83 days long summer Antarctic expedition at the J. G. Mendel Czech Antarctic Station. Our novel approach includes daily recordings of sleep heart rate and weekly assessments of emotions, stress, and sleep quality. Associations between variables were analyzed using the generalized least squares method, providing unique insights into nuances of adaptation. The results support previous findings by providing empirical evidence on the stress reducing effect of Antarctic summer expedition and highlight the importance of previous experience and positive emotions, with the novel contribution of utilizing physiological data in addition to psychological measures. High-frequency sampling and combination of psychological and physiological data addresses a crucial gap in the research of stress. This study contributes valuable knowledge to the field of psychophysiology and has implications for expedition planners, research organizations, teams in action settings, pandemic prevention protocols, global crises, and long-duration spaceflight missions. Comprehensive insights promote the well-being and success of individuals in extreme conditions.
摘要：
南极洲为研究人类的适应性提供了独特的环境,以受控条件为特征，有限的感官刺激，以及物流和通信方面的重大挑战。这项纵向研究调查了压力指标之间的关系，特别关注平均睡眠心率，在J.G.孟德尔捷克南极站进行的COVID-19检疫和随后83天的夏季南极考察期间。我们的新方法包括每天记录睡眠心率和每周评估情绪，压力，和睡眠质量。使用广义最小二乘法分析变量之间的关联，提供对适应的细微差别的独特见解。结果通过提供有关南极夏季考察的减压效果的经验证据来支持先前的发现，并强调了先前经验和积极情绪的重要性，除了心理测量之外，还利用了生理数据。高频采样以及心理和生理数据的组合解决了压力研究中的关键差距。这项研究为心理生理学领域贡献了宝贵的知识，并对探险计划者具有启示意义。研究机构,行动设置中的团队，大流行预防协议，全球危机,和长期的太空飞行任务。全面的见解促进个人在极端条件下的福祉和成功。
