The second is ice compress, which carries out heat exchange and conduction with flowing blood through ice placed in large blood vessels of the whole body. At the same time, it can reduce oxygen consumption of brain cells, delay brain cell damage, and be beneficial to body microcirculation.
The third is to lower the ambient temperature, and don't wear too thick clothes.
The causes of fever can be divided into exogenous and internal injuries. Exogenous fever is caused by feeling the evil of six evils and the qi of epidemic disease; Internal injuries and fever are mostly caused by diet fatigue or changes of seven emotions, which leads to imbalance of yin and yang and deficiency of qi and blood. Exogenous fever is excessive, which can be seen in cold, typhoid, epidemic febrile disease, plague and other diseases; There are many internal injuries, such as yin deficiency fever, yang deficiency fever, blood deficiency fever, qi deficiency fever, fatigue fever, yang floating fever, blood loss fever and so on.

Extended data:
The highest tolerance temperature of human body is 40.6 ~ 41.4℃ (105.08 ~106.52f), and the rectal temperature keeps rising over 4 1℃, which can cause permanent brain damage. High fever lasting above 42℃ for 2 ~ 4 hours often leads to shock with serious complications. When the body temperature is as high as 43℃, it rarely survives.
According to the heat type and clinical characteristics, it can be divided into acute fever (the heat range is less than 2 weeks), long-term fever (the heat range is more than 2 weeks and the body temperature is above 38℃ for many times), and repeated fever (periodic fever). It is generally believed that infection is the first cause of acute fever, followed by tumor and vascular-connective tissue disease. These three types of causes summarize the etiological diagnosis of 90% fever with unknown causes.
