Causes of sauna days in three northeastern provinces

Because of the rich water vapor and high air humidity in summer, when the temperature is not too high (relatively speaking), people feel sultry, just like in a steamer. Such weather is called sultry and high temperature. Because people like to take a sauna in this weather, it is also called "sauna day".

The hot and humid "sauna day" is like a big steaming room, fumigating everyone in the city. The public should prevent diseases such as heatstroke, colds and diarrhea.
