由于高温作用于人体所引起的急性疾病,一般称为中暑。它的发生是由于在高温生产环境或烈日下长期工作,人体体温调节发生障碍和水盐平衡遭到破坏而引起的。根据发病机制,一般将中暑分为三大类型,即热射病、热痉挛、日射病。但三者之间还存在着各种移行型或混合型,很难严格的区别。因此,把三种类型看作同一疾病不同程度的临床表现,是比较合理的。(1)热射病:由于人体从外界吸收的热量,显著超过向外界排出的热量,使体温调节发生障碍,产生热蓄积而引起。主要症状有头痛、头晕、口渴、恶心、心慌、眼花、全身疲乏、出汗多、体温升高,重者可发生昏倒。
Due to the high temperature on the human body caused by acute disease, commonly known as heat stroke. It occurs because of long-term work in high-temperature production environment or the sun, human body temperature regulation obstacles and water and salt balance is destroyed. According to the pathogenesis, heat stroke is generally divided into three types, namely, heat-induced fever, hot spasms, sun-ray disease. However, there are still a variety of migration between the three or mixed, it is difficult to strictly distinguish. Therefore, the three types of the same disease as different levels of clinical manifestations, is more reasonable. (1) heat-induced fever: As the body absorbs heat from the outside world, significantly more than the heat emitted to the outside world, so that regulation of body temperature barriers occur, resulting in heat accumulation. The main symptoms are headache, dizziness, thirst, nausea, palpitation, vertigo, body fatigue, sweating and more, elevated body temperature, severe cases can occur collapsed.
