Introduction to dog days:

Three volts, the initial, middle and final volts, is the hottest period of the year. "V" means being forced to hide underground.

The dog days appear in the Gregorian calendar from mid-July to mid-August every year, and its climatic characteristics are high temperature, low pressure, high humidity and low wind speed. The so-called "heat is in three volts" can be divided into initial, middle and final three volts, and its date is determined by the date of the solar terms.

The dog days are characterized by high temperature, low pressure, high humidity and low wind speed. Research shows that the air humidity is high, the wind speed is low, it is difficult for sweat to evaporate quickly, and it is difficult for human body to dissipate heat, which restricts body temperature regulation.
