摘要
研究目的我们的研究旨在评估热应激对高温环境下户外工作者的水分摄入和认知能力的影响：方法： 使用 Quest Temp WBGT 监测器测量区域热应激评估。方法：使用 Quest Temp WBGT 监测器测量区域热应激评估值，并使用标准程序记录脱水的出汗率和急性认知处理的反应时间：热应激测量值介于 23.8 °C - 42 °C 之间。当暴露在高温环境中时，50% 以上的工人出汗率较高（>1.2 升/小时）。WBGT、出汗率和反应时间之间呈正相关，这表明高热对神经网络处理有影响。心率和反应时间也随着 WBGT 的升高和大量运动而增加：结论：在热应激条件下，认知功能（反应时间）会受到损害。因此，反应时间可用于评估热应激对神经调节的短期影响，并有助于规划有效的干预策略，降低工人的发病率和死亡率。
Impact of heat stress on thermal balance, hydration and cortical response among outdoor workers in hot environment - an exploratory report from North East India.
Objective: The objective of our study was to assess the impact of heat stress on hydration and cognition among outdoor workers in hot environment.
Methods: Area heat stress assessments were measured using Quest Temp WBGT monitor. Sweat rate for dehydration and reaction time for acute cognitive processing were recorded using standard procedures.
Results: Heat stress measurements ranged from 23.8 °C - 42 °C. More than 50 % of the workers had high sweat rate (>1.2 L/h) when exposed to high environmental temperatures. Positive correlation was obtained between WBGT, sweat rate and reaction time which indicates that hyperthermia has an impact on neural network processing. Heart rate and reaction time also increased with rise in WBGT and heavy physical activity.
Conclusions: There was impairment of cognitive functions (reaction time) under heat stress conditions. Hence, reaction time can be used to assess the short-term impact of heat stress on neural modulation and will help to plan effective intervention strategies to reduce morbidity and mortality among workers.
期刊介绍：
The Journal of Basic and Clinical Physiology and Pharmacology (JBCPP) is a peer-reviewed bi-monthly published journal in experimental medicine. JBCPP publishes novel research in the physiological and pharmacological sciences, including brain research; cardiovascular-pulmonary interactions; exercise; thermal control; haematology; immune response; inflammation; metabolism; oxidative stress; and phytotherapy. As the borders between physiology, pharmacology and biochemistry become increasingly blurred, we also welcome papers using cutting-edge techniques in cellular and/or molecular biology to link descriptive or behavioral studies with cellular and molecular mechanisms underlying the integrative processes. Topics: Behavior and Neuroprotection, Reproduction, Genotoxicity and Cytotoxicity, Vascular Conditions, Cardiovascular Function, Cardiovascular-Pulmonary Interactions, Oxidative Stress, Metabolism, Immune Response, Hematological Profile, Inflammation, Infection, Phytotherapy.
