The purpose of this article is to review and discuss and current preventive and healable measures of heat illness and abstract scientific programs to prevent and cure heat illness.In order to suit with the PLA"s current fight direction and to improve the army"s capacity and levels of the rear service, to keep soldiers healthy and strong in the heat stress environment, by the way of systemic evaluation, we collect a series of successful work and research experience about the heat illness prevent and treatment. After analyzing and comparing these results, then based on the theories of the preventive medicine, we have try out further adaptable programs to prevent heat illness. It consists of 5 chapters, such as "heat acclimatization, water and electrolyte supplement, regulated work/rest cycle limits, lower temperature equipment, drug preventing heat stress".

为有效降低热环境因素对部队的威胁，提高部队的战斗力和应急保障水平，有针对性地形成热区部队中暑防治保障预案，与目前特定的作战方向相适应，我们根据部队当前状况，立足部队应用，大量收集了有关文献，通过应用系统的评价方法，对耐热锻炼、水盐补充、调整作息制度、防暑降温装置和药物防暑这几项主要防暑措施的实施方法进行了全面分析比较和评价，提出了更进一步的修正意见，提炼出了适合当前部队应用的方法，使其更加适于部队的应用；同时，还对中暑急救与治疗方面的有关文献也进行了概括和总结，并根据中暑的发病特点和救治重点，为部队中暑的救治设计了现场急救装置。
