在工作中暴露于极端高温是一种严重的职业危害，因为暴露可能导致与高温有关的疾病，并与事故和伤害的风险增加有关。本研究旨在探讨热暴露是否与个体风险评估心理过程的变化有关，以及习服是否可以减轻热暴露的影响。本研究采用准实验研究设计，比较了男性受试者（N = 6）暴露于热环境、对照组（N = 5）和女性受试者（N = 6）暴露于环境温度时在基线、初始暴露于热环境和适应后暴露时的风险认知和冒险行为。结果表明，参与者认为相同的风险行为风险较低（p = 0.003），并在初始热暴露后表现出增加的冒险行为（p = 0.001）。虽然他们的风险认知在适应环境后恢复到基线水平，但他们的冒险行为仍然增加（p = 0.031）。没有暴露在高温下的参与者在风险认知和风险承担方面没有显着波动。我们的研究结果支持与风险相关的过程可以解释热暴露对增加事故和伤害的影响，而不仅仅是对热相关疾病的直接影响。(C)2017爱思唯尔有限公司版权所有
Exposure to extreme heat at work is a serious occupational hazard, as exposure can result in heat-related illnesses, and it has been linked to increased risk of accidents and injuries. The current study aimed to examine whether heat exposure is related to changes in individuals' psychological process of risk evaluation, and whether acclimatization can mitigate the effect of heat exposure. A study with quasi experiment research design was used to compare participants' risk perceptions and risk-taking behaviors at baseline, initial exposure to heat, and exposure after acclimatization across male participants who were exposed to heat (N = 6), and males (N = 5) and females (N = 6) who were in the control group who were exposed to ambient temperature. Results show that participants perceived the same risky behaviors to be less risky (p = 0.003) and demonstrated increased risk-taking behaviors (p = 0.001) after initial heat exposure. While their risk perceptions returned to baseline level after acclimatization, their risk-taking behaviors remained heightened (p = 0.031). Participants who were not exposed to heat showed no significant fluctuation in their risk perceptions and risk-taking. Our findings support that risk related processes may explain the effects of heat exposure on increased accidents and injuries beyond its direct impact on heat-related illnesses.
