摘要
研究旨在探究高温高湿环境下高强度劳动对人体生理与主观疲劳的影响规律。通过模拟施工现场环境(温度35℃,湿度70%RH),选取9名健康受试者进行个性化高强度运动实验,监测心率、血压、皮肤温度、口腔温度、鼓膜温度及主观疲劳指数等指标。实验结果表明,高温高湿环境下劳动显著加剧生理负荷:心率、皮肤温度、口腔温度、鼓膜温度与主观疲劳指数显著上升(p<0.05),体力工作效率(握力值)显著下降(p<0.05),脑力工作效率无显著差异(p>0.05)。研究揭示了高温高湿环境下高强度劳动后疲劳的变化规律,以及相应的健康风险,为优化施工环境管理、制定劳动保护措施提供了科学依据。
This study aims to investigate the impact of high-intensity labor on human physiological responses and subjective fatigue under high-temperature and high-humidity environments.By simulating on-site construction conditions(temperature:35°C,humidity:70%RH),nine healthy participants were recruited for personalized high-intensity exercise experiments.Key indicators,including heart rate,blood pressure,skin temperature,oral temperature,tympanic temperature,and subjective fatigue index,were monitored.Results revealed that high-temperature and high-humidity environments significantly exacerbated physiological stress:heart rate,skin temperature,oral temperature,tympanic temperature,and subjective fatigue index increased markedly(p<0.05),while physical work efficiency(measured by grip strength)declined significantly(p<0.05).No significant difference was observed in mental work efficiency(p>0.05).The study elucidates fatigue accumulation patterns and associated health risks under such extreme environmental conditions,providing a scientific basis for optimizing construction environment management and formulating labor protection measures.
