热习服是一种对热环境的适应性机制,不仅对热损伤具有保护作用,还可产生交叉耐受现象。虽然关于热习服的研究历史悠久,但不同学者提出了多种机制,热习服的交叉耐受现象是近年来相关领域研究的热点。本文综述了热习服及其交叉耐受的研究进展,以期对其卫生学意义有更好的认识。 Hot acclimatization is a mechanism of adaptation to the thermal environment, not only has a protective effect on thermal damage, but also can produce cross-tolerance phenomenon. Although the research on the heat service has a long history, many scholars put forward a variety of mechanisms. The cross tolerance of the heat service is a hot topic in recent years. This review summarizes the progress of research on heat acclimatization and its cross-tolerance, with a view to gaining a better understanding of its health implications.
