This study assessed the effect of season on cognitive function and psycho-physiological responses during a 14-day swing in mine-service workers. Cognitive function, thermal sensation and comfort, rating of perceived exertion, fatigue, hydration, core temperature and heart rate were assessed throughout a shift, on three separate days over a swing. Working memory and processing efficiency did not differ between seasons (p > 0.05), however counting and recall latencies improved throughout the swing (p < 0.05). Participants reported greater fatigue post-shift compared to pre-shift (p < 0.05). Thermal sensation, thermal comfort, and hydration were significantly elevated in summer compared to winter (p < 0.05). Specifically, workers were significantly/minimally dehydrated in summer/winter (urinary specific gravity = 1.025 ± 0.007/1.018 ± 0.007). Although cognitive function and thermal strain were not impaired in summer compared to winter, it is essential to reinforce worker's knowledge regarding hydration requirements. Additional education and/or incorporating scheduled rest breaks for hydration should be considered to ensure the health and safety of mine workers.

矿山服务人员认知功能和心理生理反应 14 天波动的季节性比较

这项研究评估了季节对矿工在 14 天的轮换期间认知功能和心理生理反应的影响。在秋千的三天内，在整个轮班期间对认知功能、热感觉和舒适度、感知用力程度、疲劳、水合作用、核心温度和心率进行评估。工作记忆和处理效率在不同季节之间没有差异（p > 0.05），但计数和回忆延迟在整个挥杆过程中有所改善（p < 0.05）。参与者表示，与轮班前相比，轮班后疲劳程度更高 (p < 0.05)。与冬季相比，夏季的热感觉、热舒适度和水合作用显着升高（p < 0.05）。具体来说，工人在夏季/冬季明显/轻微脱水（尿比重 = 1.025 ± 0.007/1.018 ± 0.007）。尽管与冬季相比，夏季认知功能和热应激并未受损，但加强工人有关水合需求的知识至关重要。应考虑进行额外的教育和/或纳入预定的补水休息时间，以确保矿工的健康和安全。
