High temperature weather refers to hot weather where the daily maximum temperature reaches or exceeds 35 ℃, and is the main meteorological disaster in summer in China. High temperature weather not only causes physiological stress related to temperature regulation, but also triggers diseases such as heatstroke, cold, stroke, diarrhea, etc. due to the human body being in a state of heat stress. It may also worsen the symptoms of existing cardiovascular and cerebrovascular diseases, among which heatstroke is the most common.
Heatstroke is not something that can be achieved overnight. Due to the effects of heat damage factors on the body, a series of pathological and physiological changes occur, which is a continuous process from mild to severe, with concealment and confusion. If not taken seriously and developed into severe heatstroke, the condition will rapidly deteriorate and even endanger life.
