A guide for preventive measures against heat disorders in hot environment

日本在18年前制定了预防体育活动中高温紊乱的指南。从那时起，人们对预防中暑的措施进行了各种研究，对其预防产生了新的认识。有报道称，儿童和老年人的中暑发病率较高，热适应和衣着是导致这种疾病的因素。我们建议将未适应环境的人、儿童、老人和穿着覆盖全身的衣服的人的WBGT警告(停止剧烈运动)的上限从28℃及以上降至25℃及以上(相当于环境温度28℃)。

The guidelines for the prevention of heat disorders during sports activities were established 18 years ago in Japan. Since then, various studies on preventive measures against heat disorders have been performed, yielding new knowledge about its prevention. It has been reported that the incidence of heat disorders is high in children and the elderly, and heat acclimatization and clothing are the factors involved in this disorder. We proposed to lower the WBGT limit for warning (discontinuation of hard exercise) from 28℃ and over to 25℃ and over (corresponding to an ambient temperature of 28℃) for non-acclimatized persons, children, the elderly, and persons wearing clothes covering the entire body.
