OBJECTIVE
Self-pacing or avoidance of physiological strain by adjustment of work rate may be an important protective behaviour for manual workers in severe thermal conditions. Data were gathered at a number of industrial sites in the United Arab Emirates to assess whether self-pacing takes place in these workers.
METHODS
Heart rate and aural temperature were monitored in 150 subjects for 12 h daily over 2 consecutive days. Environmental parameters were measured for quantification of heat stress by the thermal work limit.
RESULTS
There was no evidence of an effect of variation in environmental thermal stress on either average working heart rate or aural temperature.
CONCLUSION
These studies provide evidence that self-pacing is a protective response to working in heat which does not require a highly informed workforce; recognition of this should form part of a holistic approach to management of heat stress in hot climates.
目的
通过调整工作速率进行自我调节或避免生理压力，对于在酷热条件下工作的体力劳动者而言，可能是一种重要的保护行为。在阿拉伯联合酋长国的多个工业场所收集了数据，以评估这些工人是否会进行自我调节。
方法
连续两天每天对150名受试者进行12小时的心率和耳温监测。测量环境参数，通过热工作极限来量化热应激。
结果
没有证据表明环境热应激的变化对平均工作心率或耳温有影响。
结论
这些研究提供了证据，表明自我调节是对高温工作的一种保护反应，这种反应并不需要劳动者具备很高的知识水平；认识到这一点应成为炎热气候下热应激管理整体方法的一部分。
