What does the dog days of summer mean?

The "Fu" in the dog days of summer means that the Yin energy is forced to hide underground by the Yang energy. The dog days of summer occur between the Lesser Heat and the End of Heat. They are the hottest, most humid and stuffy days of the year . There are three dog days every year, starting from the summer solstice. According to the arrangement of the days based on the stems and branches, the first dog day starts on the third Geng day. The fourth Geng day is the middle of the dog days, and the first Geng day from the beginning of autumn is the first day of the last dog days, which lasts ten days.
The dog days of summer are the best time for people to maintain their health. Chinese medicine believes that "summer is hot and humid, and it is suitable for clearing and nourishing". In the hot summer, people like cold drinks and drink a lot of water, which causes moisture to invade the human body. The external moisture enters the body, causing the spleen to rise and fall, which in turn causes digestive function disorders, water accumulation, and loss of appetite. Summer heat and dampness are very harmful to the spleen, and bitter foods have the function of purging dryness, so they should not be eaten too much. Therefore, it is appropriate to eat more sweet and cool or sweet and cold foods in your daily diet. Moreover, summer is the season of the heart, which likes coolness and responds to sour food. Therefore, you should eat more acidic food in summer.

Why do we say “the heat is in the dog days”?

After the beginning of the dog days, the humidity of the ground becomes higher, and it absorbs more heat every day and emits less heat. The heat on the surface accumulates, so it gets hotter day by day. When the dog days begin, the accumulated heat on the ground reaches its peak, and the weather is the hottest. In addition, there is more rain in summer and the air humidity is high. The heat capacity of water is much greater than that of dry air, which is also an important reason for the hot and humid weather. The subtropical high pressure strengthens in July and August. Under the control of the subtropical high pressure, the downward air flow inside the high pressure makes the weather clear and cloudless, which is conducive to sunlight and ground radiation warming, making the weather even hotter.
