Slight summer heat is the most vigorous time of human yang, "nourishing yang in spring and summer". Therefore, when people are working, they should pay attention to the combination of work and rest to protect the yang of the human body. Although it is not the hottest season in a year, it is followed by the hottest season in a year. There is a folk saying that "it is a little summer and a big summer, and it is cooked and eaten". This is a busy time for people to grow vegetables and prepare for winter. At this time, most areas in China are also busy with the field management of summer and autumn crops. In a hot climate, people should not neglect health care because of sweating, high consumption and fatigue.

"The heat is in the dog days", which is the beginning of entering the dog days. "Squat" means hiding, so people should go out for the summer less. The way people spend the dog days is to eat cold food to cool off the heat. As the saying goes, "jiaozi covers his head with two volts, and pancakes spread eggs with three volts". This way of eating is to make the body sweat more and expel all kinds of toxins from the body.
