1 and the origin of dog days

The origin of dog days can be traced back to the ancient farming society in China. The ancients observed that there was a period in summer when the weather was particularly hot and the sun was scorching, and crops grew rapidly, which was also a period prone to diseases. Therefore, people began to divide this period into three stages, called dog days.

According to records, the dog days first appeared in the Southern and Northern Dynasties, that is, between the 4th and 6th centuries. The ancients corresponded the first, middle and last three days to the long summer, light summer and great summer in the summer calendar.

The initial stage usually starts from Chang Xia Hou 1 1 day, the intermediate stage starts from Chang Xia Hou 2 1 day, and the final stage starts from Chang Xia Hou 3 1 day, and each stage lasts1day.

In ancient times, the dog days were considered to be the period when the yang was the most vigorous and the yin was relatively weak. It is believed that in dog days, the human body is easily affected by external heat evil, so it is prone to heatstroke and other health problems related to high temperature.

In order to prevent the occurrence of diseases, people will adopt some special eating and living habits, such as drinking more cold drinks and avoiding long-term activities in the scorching sun.
