This study determined the association of cold-related symptoms with workplace temperature and thermal insulation of clothing among Thai chicken industry workers. Three hundred workers were interviewed regarding cold-related symptoms, which were regressed on worksite temperature and protective clothing. In total, 80% of workers reported respiratory symptoms; 23%, cardiac symptoms; 62%, circulation disturbances; 42%, thirst; 56%, drying of the mouth; and 82%, degradation of their performance. When adjusted for personal characteristics, respiratory symptoms were 1.1‒2.2 times more prevalent at −22‒10°C than at 10‒23°C. At −22‒10°C, cardiac symptoms increased by 45%, chest pain by 91%, peripheral circulation disturbances by 25%, and drying of the mouth by 57%. Wearing protective clothing with at least 1.1 clo units was associated with marked reductions in symptom prevalence. Therefore, temperatures lower than 10°C increased prevalence of cold-related symptoms, which are largely preventable by appropriate clothing use.

这项研究确定了泰国养鸡业工人中与寒冷有关的症状与工作场所温度和衣服隔热的关系。就与感冒相关的症状对300名工人进行了采访，这些症状在工作场所的温度和防护服上有所降低。共有80％的工人报告了呼吸道症状；23％，心脏症状；62％，循环障碍；42％口渴；56％，口干；82％的广告会降低其性能。如果根据个人特征进行调整，则呼吸症状在-22×10°C时的流行度是10°23°C时的1.1〜2.2倍。在-22±10°C下，心脏症状增加45％，胸痛增加91％，周围循环障碍增加25％，口干增加57％。穿着至少有1。1个clo单位与症状发生率显着降低有关。因此，低于10°C的温度会增加与感冒相关的症状的患病率，这可以通过适当的穿着衣物来很大程度上预防。
