Heat-related illness (HRI) is a common occupational injury, especially in construction workers. To explore the factors related to HRI risk in construction workers under hot outdoor working conditions, we surveyed vital and environmental data of construction workers in the summer season. Sixty-one workers joined the study and the total number of days when their vital data during working hours and environmental data were recorded was 1165. Heart rate with high-risk HRI was determined using the following formula: 180 - 0.65 × age. As a result of the logistic regression analysis, age, working area, maximum skin temperature, and heart rate immediately after warming up were significantly positively related, and experience of construction was significantly negatively related to heart rate with high-risk HRI. Heart rate immediately after warming up may indicate morning fatigue due to reasons such as insufficient sleep, too much alcohol intake the night before, and sickness. Asking morning conditions may lead to the prevention of HRI. For occupational risk management, monitoring of environmental and personal conditions is required.
热相关疾病（HRI）是一种常见的职业伤害，尤其是在建筑工人中。为了探讨在炎热户外工作条件下建筑工人 HRI 风险相关因素，我们调查了夏季建筑工人的生命和环境数据。61 名工人参加了这项研究，记录了他们工作时间生命数据和环境数据的总天数为 1165 天。使用以下公式确定有高风险 HRI 的心率：180-0.65×年龄。由于逻辑回归分析，年龄、工作区域、最大皮肤温度和热身后立即的心率呈显著正相关，而建筑经验与有高风险 HRI 的心率显著负相关。热身后立即的心率可能表明由于睡眠不足、前一天晚上饮酒过多、生病等原因导致早晨疲劳。询问早晨的情况可能有助于预防 HRI。对于职业风险管理，需要监测环境和个人条件。
