What is the concept of a temperature of 33 degrees?
When the daily maximum temperature reaches or exceeds 35℃, it is called high temperature, and the high temperature weather process that lasts for several days (more than 3 days) is called high temperature heat wave (also called high temperature heat wave). Due to the frequent occurrence of high temperature and heat waves in recent years, the disasters caused by high temperature are becoming more and more serious. To this end, China's meteorological departments have specially formulated high-temperature warning signals to defend against high-temperature weather.
The high temperature of 34℃ is a threshold. In daily life, whether it is cold or hot, it will cause physical discomfort. People's normal body temperature is maintained at around 37℃. According to international experiments, the comfortable temperature of human body is 19℃~24℃ in summer and 12℃~22℃ in winter. Therefore, in the hot summer, when the humidity is high and the temperature reaches 34℃, people need to pay attention. When the temperature and humidity reach a certain limit, the human body's heat cannot be dissipated, and the body temperature will rise, exceeding the human body's tolerance limit, causing fatal accidents.
